Dangerous Goods to Canada: TDG Rules for China Exporters
Introduction
Every week, freight forwarders in Shenzhen, Ningbo, Shanghai and Qingdao hear the same question from factory owners and cross-border sellers: can this product go to Canada, and what do we need to do to make it legal? The answer is almost always yes, provided the cargo is classified correctly, packed in approved packaging, described accurately on paper and handed to a carrier that is willing to move it. What catches exporters out is rarely the existence of the rules. It is the fact that two different regimes apply to the same carton at different points of its journey.
On the Chinese side, the cargo is governed by China’s export requirements for dangerous goods and by the international modal codes, the IMDG Code for ocean freight and the IATA Dangerous Goods Regulations for air freight. Once the goods land in Canada, the Transportation of Dangerous Goods Act, 1992 and the Transportation of Dangerous Goods Regulations, usually shortened to the TDG Regulations or TDGR, take over for every kilometre moved by truck or rail from the port to the consignee’s door. Transport Canada enforces them, and its inspectors will stop a shipment whose marks, documents and contents do not tell the same story.
2026 has added a new layer. Transport Canada published a major amendment package, registered as SOR/2026-112, in the Canada Gazette, Part II, on June 17, 2026. It rewrites the air transport rules in Part 12 and pushes Canada’s rules further towards the UN Model Regulations, the IMDG Code, the ICAO Technical Instructions and the US 49 CFR. This guide explains what the TDG rules mean in practice for Chinese exporters, what has changed this year, which mistakes cost the most money, and how to build a repeatable workflow so dangerous goods bound for Canada arrive on schedule instead of sitting in a terminal.
How the Canadian TDG System Is Built
The legal structure is simple to describe and tedious to apply. The Transportation of Dangerous Goods Act, 1992 is the framework statute. The TDG Regulations, registered as SOR/2001-286, contain the detailed rules, and the Justice Laws website shows the consolidated text as current to June 17, 2026. The Regulations in turn incorporate by reference a long list of standards, including Canadian General Standards Board packaging standards, CSA standards for cylinders and tanks, and the international modal codes. A shipper who reads only the main text of the Regulations will miss a good part of what is actually required.
The parts of the Regulations that matter most to an exporter are easy to remember. Part 2 deals with classification, Part 3 with shipping documents, Part 4 with safety marks such as labels and placards, Part 5 with the standards for packaging and other means of containment, Part 6 with training, Part 7 with Emergency Response Assistance Plans, Part 8 with reporting accidental releases, and Part 12 with air transport. Each part contains exceptions, special provisions and quantity-based exemptions, which is why two shipments of the same product can be treated very differently depending on the amount per package and per transport unit.
Canada also layers other federal rules on top of the transport rules. Explosives such as fireworks need authorization under the Explosives Act administered by Natural Resources Canada. Pesticides need registration with Health Canada’s Pest Management Regulatory Agency. New chemical substances may need notification to Environment and Climate Change Canada. Radioactive materials involve the Canadian Nuclear Safety Commission. None of these bodies cares whether the carton was packed perfectly for transport; they care whether the product may enter the country at all. A forwarder who checks transport compliance but ignores product-entry rules can still end up with a container held at the terminal.
Who Is Responsible: Exporter, Importer, Carrier and Forwarder
Responsibility is the single most misunderstood point in China-to-Canada dangerous goods shipping. Many Chinese factories assume that once the cargo has been loaded and the bill of lading issued, their obligations end. Many Canadian importers assume the opposite, that the shipper in China has handled everything and that the goods will arrive ready to deliver. Neither assumption is safe, because the TDG system assigns duties to whoever is acting as the consignor, the carrier or the consignee at each stage.
The Chinese Shipper
The factory or trading company in China is responsible for classifying the product, selecting UN-certified packaging that has been properly tested and used within its limits, marking and labelling the packages, and supplying an accurate Safety Data Sheet. It must also complete the dangerous goods declaration for the modal carrier and keep records that support every statement on the declaration. For ocean freight, Chinese customs and the port authorities typically require evidence that the packaging has been inspected for dangerous goods export use, so the shipper should confirm the current inspection and certificate requirements with its local customs broker before packing.
The Canadian Importer
Under the TDG framework, the party that imports dangerous goods into Canada or offers them for transport inside Canada generally takes on the duties of a consignor. In practical terms, that means the importer or its customs broker is answerable to Transport Canada for the shipping document that accompanies the goods on the road or rail leg, for the safety marks being correct, and for the Emergency Response Assistance Plan when one is required. If the Chinese shipper has supplied wrong information, the Canadian party is still the one standing in front of the inspector, which is why serious importers audit their suppliers before the first order rather than after the first violation.
The Forwarder and Carrier
The freight forwarder or NVOCC sits between the two and usually decides whether the shipment can move at all. Forwarders check the declaration against the SDS, confirm the carrier will accept the UN number and class on the chosen service, and make the booking. Ocean carriers and consolidators carry their own acceptance rules that can be stricter than the law. The trucking company and the railway on the Canadian side then take responsibility for transporting the goods in line with the Regulations. Each party can be held accountable for its own part of the chain.
Table 1. Who does what on a China-to-Canada dangerous goods shipment
| Party | Main responsibilities before Canada | Main responsibilities in Canada |
| Chinese shipper | Classification, SDS, UN packaging, marks and labels, DG declaration, China export inspection | Provides accurate data and a reachable contact for questions |
| Freight forwarder / NVOCC | Document check, carrier acceptance, booking, container packing coordination | Passes correct data to the Canadian broker and carrier |
| Ocean carrier | Accepts or refuses the cargo, stowage and segregation under IMDG | Delivers to terminal; may restrict certain classes |
| Canadian importer | Confirms product may be imported, arranges ERAP and training if needed | Acts as consignor for the inland leg; answers to Transport Canada |
| Canadian broker and trucker | Customs entry, advance cargo data | TDG shipping document, placards, safe delivery to consignee |
What Changed in 2026: The Part 12 and International Harmonization Update
The amendment package published on June 17, 2026 did not appear out of nowhere. Transport Canada had been consulting on it since the proposal first appeared in the Canada Gazette, Part I, in November 2022, and the department has stated publicly that aligning the TDG Regulations with international codes is a priority because misalignment imposes costs on shippers and carriers who have to satisfy two sets of rules for the same goods. For Chinese exporters the practical value is that a Canadian shipment prepared to international standards is now less likely to need rework once it reaches the Canadian side of the border or port.
The package covers many topics, and only some affect an exporter directly. Air shipments are affected by the full rewrite of Part 12, including a move to monthly electronic reporting of undeclared or misdeclared dangerous goods in place of immediate reporting by phone. Packaging suppliers are affected by changes to the standards that the Regulations incorporate. Everyone who prints labels or documents should look closely at the revised rules on marks, languages and formatting. Table 2 summarizes the items most relevant to China-based shippers, based on Transport Canada’s published amendments and industry summaries available at the time of writing.
Table 2. 2026 changes most relevant to China exporters
| Area | What changed in practice |
| Lithium battery mark | The requirement to show an emergency telephone number on the lithium battery mark has been removed, aligning the mark with the international version. |
| Air transport of lithium-ion batteries | The state-of-charge limit of 30 percent for lithium-ion cells and batteries shipped by air is aligned with ICAO and IATA expectations. |
| Limited quantity mark | The mark must be durable and legible on at least one side and must not be placed on the top or bottom of the package. |
| Language on labels and placards | Required wording on labels and placards may appear in either English or French. |
| Document formatting | Apart from the proper shipping name, capitalization, spelling and punctuation in shipping document text may follow UN or US 49 CFR formats. |
| UN number on labels | UN numbers may be shown inside hazard labels in a rectangular box, with sizes for small packages aligned to IMDG and ICAO rules. |
| Packaging standards | CAN/CGSB-43.150 replaces TP 14850 and CAN/CGSB-43.126; CGSB-43.145, 43.147 and 43.149 cover large packagings, rail tank cars and ton containers. |
| 150 kg and 500 kg gross mass exemptions | Wording clarified to state which requirements are exempt and under what conditions. |
| US recognition | Greater recognition of US special permits and US inhalation hazard marks for cross-border movements. |
Timing deserves care. Transport Canada has historically allowed a six-month transition after publication during which shippers may follow either the old or the new rules, and at least one industry compliance guide published in 2026 points to June 4, 2027 as the date by which the main changes must be fully followed. Because individual provisions can carry their own coming-into-force dates, exporters should not rely on a single date they have read in a blog post. Ask your Canadian importer or forwarder to confirm which version of each provision applies to your sailing date, and keep that confirmation with the shipping file.
The harmonization also has a flip side. Flexibility for Canada–US movements does not mean that following one country’s rules automatically satisfies the other’s. A container routed from Shenzhen through a US port and then into Canada still has to be checked against both countries’ requirements, which is one more reason to route dangerous goods directly to Canadian ports wherever the schedule allows.
Classification and UN Numbers: Getting the Basics Right
Everything else in the process depends on classification. The UN number, the proper shipping name, the class, the packing group and any subsidiary risks decide which packaging you must use, which labels go on the box, which limits apply per package, how the goods may be stowed on the vessel and whether an ERAP is needed in Canada. A wrong classification is the most expensive mistake an exporter can make, because it contaminates every document that follows it.
Canada uses the same nine hazard classes as the UN Model Regulations and the IMDG Code. Table 3 lists them with examples of products that regularly leave Chinese factories bound for Canada, and flags the points that tend to cause trouble.
Table 3. Hazard classes and typical China-to-Canada products
| Class | Name | Typical products | Watch-outs for Canada |
| 1 | Explosives | Fireworks, flares, ammunition | Needs Natural Resources Canada authorization; most consolidators refuse it |
| 2 | Gases | Aerosols, lighters, refrigerant gas, cylinders | Cylinder specifications and quantity limits; some toxic gases need ERAP |
| 3 | Flammable liquids | Paint, adhesive, ink, nail polish, perfume | Packing group and flash point must match the SDS; limited quantity rules apply |
| 4 | Flammable solids | Matches, sulphur, magnesium products | Water-reactive and self-heating goods need extra care in containers |
| 5 | Oxidizers and organic peroxides | Pool chemicals, bleaching agents, peroxide | Segregation from flammables; temperature control for some peroxides |
| 6 | Toxic and infectious | Pesticides, reagents, lab samples | Pesticides need Health Canada registration; infectious items need special handling |
| 7 | Radioactive | Industrial gauges, sources | Requires Canadian Nuclear Safety Commission involvement |
| 8 | Corrosives | Cleaners, acids, lead-acid batteries | Leak-proof inner packaging and absorbent material are often checked |
| 9 | Miscellaneous | Lithium batteries, magnets, dry ice | Largest share of e-commerce dangerous goods; see the lithium section below |
Classification and the Safety Data Sheet
Most classification disputes start with the Safety Data Sheet. Chinese SDS documents are often prepared to the national GB format, and they sometimes show a transport section that lists a UN number but leaves the flash point, packing group or test result unclear. Forwarders should read Section 14 of the SDS together with the physical and chemical properties in Section 9. If the flash point is 21 degrees Celsius and the document claims packing group III, the declaration is wrong, and the carrier’s DG desk will spot it.
Canada also has a separate workplace regime, the Workplace Hazardous Materials Information System, under which a hazardous product sold or imported for use in a Canadian workplace needs a supplier label and an SDS in both English and French. This is not the same thing as the TDG rules, but the two overlap in practice because the importer will ask for the SDS in both formats at the same time. Preparing a bilingual SDS early saves your Canadian buyer a delay later.
Packaging, Marks and Labels
The TDG Regulations expect packaging to be designed, tested and used in accordance with the standard that applies to the goods. For most non-bulk goods that means a UN-specification package that carries the UN marking and conforms to CAN/CGSB-43.150, which, following the 2026 amendments, consolidates requirements that were previously spread over several documents. Large packagings such as intermediate bulk containers fall under CGSB-43.145, and rail tank cars and ton containers have their own standards. Because the standards are incorporated by reference, a UN packaging that is certified by a competent authority in China and used within its tested limits is normally accepted at the Canadian end, but the markings must be legible and the use must match the certification.
Exporters should be careful with the performance rating. A box that was tested for a certain gross mass, specific gravity and packing group cannot be loaded with a heavier or more hazardous product just because it looks sturdy. Inspectors in Canada and carriers in China will check the UN code on the package against the goods and the declared packing group, and a mismatch can result in the package being rejected or the shipment being rewritten at the exporter’s expense.
Marks, Labels and Placards
Each package must show the proper shipping name, the UN number prefixed by the letters UN, and the hazard labels corresponding to the class and any subsidiary risk. For ocean containers, placards and the UN number panel on all four sides of the container are standard under the IMDG Code, and the TDGR expects the same visibility once the container is moving on Canadian roads or rail. The 2026 amendments make it easier on the language front by accepting required words in either English or French, and by allowing UN numbers to appear within a label, but they do not allow marks to be hidden, damaged or placed where a handler cannot see them.
The limited quantity mark deserves its own mention because e-commerce products such as aerosols, nail polish, perfume and cleaning sprays often move under limited quantity rules. Under the revised text, the mark must be durable, legible and on at least one side of the package, but not on the top or the bottom. A shipper that has pre-printed cartons with the mark on the lid will need to change the artwork.
Table 4. Packaging and marking checklist before loading
| Item | What to confirm |
| UN packaging code | The code on the package matches the product, packing group and gross mass being shipped |
| Proper shipping name and UN number | Printed legibly on the outer package and identical to the declaration |
| Hazard labels | Correct class and subsidiary risk labels, in good condition, not covered by tape |
| Orientation arrows and closure | Required for liquids in combination packaging; closures secure |
| Limited quantity mark | On at least one side, not on top or bottom, only for qualifying quantities |
| Container placards | All four sides of the container with the UN number displayed |
| Container packing certificate | Signed by the person who packed the container for ocean shipments |
Shipping Documents Canada Expects
Documents are where most shipments live or die. For ocean freight out of China, the primary documents are the dangerous goods declaration in the IMDG format, the container or vehicle packing certificate, the bill of lading marked to show dangerous goods, the commercial invoice and the packing list, together with the SDS. When the container clears at a Canadian port and the goods move inland, a TDG shipping document is needed for the road or rail leg. In many cases the Canadian broker or carrier prepares it from the IMDG declaration, which is why the information on the declaration has to be complete.
A Canadian shipping document normally shows the consignor’s name and address, a description of the dangerous goods that includes the UN number, the proper shipping name, the primary class and any subsidiary class, the packing group where applicable, and the quantity and number of packages. It also shows an emergency telephone number that is answered at all times during transport by a person who has detailed knowledge of the goods and what to do in an emergency, and the ERAP reference number where an ERAP is needed. If the cargo includes residue in an empty container, the 2026 amendments clarify when the words Residue or Residue Last Contained should appear on the document.
The cargo data that the ocean carrier sends to the Canada Border Services Agency before loading at the foreign port also flags dangerous goods and normally includes the UN number. A mismatch between that electronic data and the physical declaration can create customs holds that have nothing to do with the TDG Regulations themselves but cost the importer just as much time.
Table 5. Core documents for ocean dangerous goods to Canada
| Document | Prepared by | Why it matters |
| Dangerous goods declaration | Chinese shipper | Legal statement of classification, packaging and quantities for the carrier |
| Container packing certificate | Packer of the container | Confirms segregation, securing and placarding of the unit |
| Safety Data Sheet | Manufacturer | Supports classification; Canadian importers may require English and French |
| Packaging inspection certificate | China inspection body | Evidence that UN packaging is suitable for the goods |
| Bill of lading and manifest | Carrier or forwarder | Marked with dangerous goods details; feeds customs cargo data |
| TDG shipping document | Canadian importer, broker or carrier | Accompanies the goods on Canadian roads and rail |
ERAP, Emergency Numbers and CANUTEC
Some dangerous goods are hazardous enough that the shipper must have a Transport Canada approved Emergency Response Assistance Plan, known as an ERAP, in place before the goods move. Whether a plan is needed depends on the UN number and the quantity, and the thresholds are published in the ERAP index column of Schedule 1 of the Regulations. Typical candidates include certain toxic gases, highly toxic liquids and large quantities of some flammable liquids. Most consumer goods exported from China fall well below these limits, but bulk chemical shipments often do not.
The ERAP is the responsibility of the consignor, which in an import scenario is generally the Canadian party. Chinese exporters therefore need to tell their buyer early if a product is on the ERAP list, because obtaining an approved plan takes time, and no one should discover the need for one when the container is already at sea. The ERAP reference number goes on the shipping document next to the emergency number.
Canada’s national emergency centre for dangerous goods incidents is CANUTEC, operated by Transport Canada and reachable at 1-888-226-8832, or 613-996-6666. Many shippers use it as the emergency response number on the shipping document where the TDGR allows, but others contract a commercial response service. Whichever arrangement is used, the number must be answered whenever the goods are in transport, and it must be a number that someone in Canada can actually dial from the road.
Lithium Batteries and Class 9: The Most Common Trouble Spot
If dangerous goods trouble were measured by volume, lithium batteries would win by a wide margin. China is the world’s largest producer of cells, power banks, e-bikes, scooters, wearables and consumer electronics that contain them, and Canada is a rapidly growing destination for all of them. Because lithium batteries can enter thermal runaway after a short circuit or damage, they are regulated as Class 9 miscellaneous dangerous goods, and every transport mode scrutinizes them closely.
The UN numbers to know are UN3480 for lithium-ion batteries shipped alone, UN3481 for lithium-ion batteries packed with or contained in equipment, UN3090 for lithium metal batteries shipped alone and UN3091 for lithium metal batteries packed with or contained in equipment. Cells and batteries must be of a type that has passed the UN Manual of Tests and Criteria, section 38.3, and the manufacturer must be able to produce a test summary. A supplier who cannot provide one should be treated as a warning sign, whatever the product’s price.
The 2026 changes help in two ways. Dropping the phone number from the lithium battery mark makes the label simpler, and the alignment of air rules with ICAO and IATA on the state of charge limit removes a source of contradictory instructions. They do not relax the substance of the rules. Packaging, wattage-hour or lithium content limits, protection against short circuits and correct declaration are all still checked. Lithium batteries that are damaged, defective or recalled are in a separate and much stricter category and should never be shipped as ordinary goods.
Ocean carriers and consolidators also set their own policies for lithium batteries, particularly for LCL. Some accept only batteries packed within equipment, some insist on additional documentation such as the UN 38.3 summary and the cell manufacturer’s certificate, and some do not accept them on specific services. Ask before you pack, not after.
Ocean, Air and Inland Modes Compared
The mode you choose changes the rules, the documents and the cost. Ocean freight is the default for volume cargo, air freight serves urgent or high-value items, and both end with a Canadian inland movement under the TDGR. Table 6 compares the main features for shippers who are choosing between them.
Table 6. Comparing modes for dangerous goods from China to Canada
| Mode | Governing rules | Typical Canadian gateways | Key points for exporters |
| Ocean FCL | IMDG Code for the sea leg; TDGR for the inland leg | Vancouver, Prince Rupert, Montreal, Halifax | Full control of packing and placarding; carrier acceptance per UN number is critical |
| Ocean LCL | IMDG Code; consolidator policy; TDGR inland | Same ports, often via Vancouver and Toronto rail ramps | Many consolidators decline some classes; longer lead time for DG approval |
| Air freight | IATA DGR and ICAO TI; TDGR Part 12 | Vancouver, Toronto, Montreal | Strict quantity limits, trained staff required, 30 percent state of charge for lithium-ion |
| Rail and truck inland | TDGR Parts 3 to 7 | Port to inland terminals and consignees | TDG shipping document, placards, ERAP where required |
For ocean freight, the choice between FCL and LCL matters even more with dangerous goods than with general cargo. An FCL container gives the exporter full control over how the goods are packed, secured and placarded, and it avoids the problem of incompatible cargo being consolidated in the same box. LCL is cheaper for small quantities, but the consolidator has to accept every shipment and must keep incompatible classes apart, so approval can take several days and not every class is accepted. Class 1 explosives and Class 7 radioactive materials are rarely accepted in LCL at all, and many consolidators restrict toxic gases, organic peroxides and infectious substances.
Cost follows the same logic. Dangerous goods are usually charged at a premium compared with general cargo, through a DG surcharge from the carrier, additional handling at the terminal and extra documentation fees. Those charges differ widely by carrier, trade lane and class, so any figure quoted in an article like this would be out of date quickly. Ask for a written quote that lists every DG-related line, and be wary of an unusually low rate, which sometimes means that the goods will be declared as general cargo, a practice that carries real legal and safety risks for everyone involved.
A Practical Workflow for a Compliant Shipment
A reliable process turns the rules above into a routine. The following four stages reflect how experienced forwarders handle China-to-Canada dangerous goods, and they can be applied to almost any product.
Before You Book
Start with the product. Collect the SDS, any test reports for flash point or corrosivity, and the lithium battery test summary if applicable. Decide the UN number, class and packing group, and then check whether the product is subject to Canadian entry rules from Natural Resources Canada, Health Canada or Environment and Climate Change Canada. Next, ask the forwarder to confirm that the chosen carrier or consolidator accepts the UN number on the intended service and to quote the DG-related charges in writing. Have the Canadian importer confirm whether an ERAP, a bilingual SDS or any special permit is required.
At Packing and Loading
Use a UN-certified package rated for the product, and make sure the inner packagings, closures and absorbent materials match the certification. Apply marks and labels, confirm the limited quantity mark position if applicable, and keep photographs of the packed cartons. For FCL, the person who packs the container completes the container packing certificate and places the placards on all four sides. Make sure incompatible goods are not loaded together and that cargo is secured against movement.
At the Port of Loading
Submit the dangerous goods declaration and supporting documents within the cut-off required by the carrier, which for dangerous goods is normally earlier than for general cargo. Check that the information on the booking, the declaration, the bill of lading and the cargo data sent to Canadian customs is identical, down to the UN number and the net quantity. A single inconsistent digit can lead to the container being rolled to a later vessel.
On Arrival in Canada
Once the container is discharged, the Canadian broker clears customs and arranges the inland movement. The TDG shipping document is produced from the declaration data, placards are checked, and the trucker or railway receives the goods under the TDGR. If the consignee is in a province with additional local requirements, such as Quebec’s bilingual labelling expectations for products sold to consumers, the importer should handle those separately from the transport rules. Keep copies of everything for at least the period required by the Regulations, since inspectors may ask for records after the delivery is complete.
Common Mistakes, Penalties and How to Avoid Them
Transport Canada enforces the TDG Act through inspections, compliance orders and, for serious or repeat violations, prosecution that can lead to substantial fines. Carriers and terminals add their own consequences, from rejected containers and demurrage charges to blacklisting of shippers who repeatedly misdeclare. The mistakes below account for a large share of the problems that forwarders see on the China–Canada lane.
Table 7. Frequent errors and how to prevent them
| Mistake | Likely consequence | Prevention |
| Declaring dangerous goods as general cargo | Cargo seizure, carrier penalties, possible prosecution | Always classify from the SDS and test data, never from price or habit |
| Using packaging not rated for the product | Rejection at the port or fines in Canada | Match the UN code to goods, packing group and gross mass |
| Missing or unreachable emergency number | Shipment held, document considered non-compliant | Use a monitored number valid for the whole time in transport |
| No ERAP where required | Goods cannot move on Canadian roads or rail | Check the Schedule 1 ERAP index with the importer before booking |
| Old labels after the 2026 changes | Marks challenged during inspection | Review artwork for lithium and limited quantity marks |
| Inconsistent data across documents | Customs hold, rolled cargo, extra storage | Use one master data sheet for every document |
| Ignoring product-entry rules | Containers held by regulators | Check Explosives Act, pesticide and chemical notification needs |
The most effective prevention is a single master data sheet per product, signed off by the person responsible for compliance, from which every document in the chain is produced. It should record the UN number, proper shipping name, class, packing group, net and gross weights, packaging codes and the lithium test summary reference. Forwarders who work from a master sheet make fewer mistakes than those who retype data for every booking.
Training is the other pillar. The TDG Regulations require that anyone who handles, offers for transport or transports dangerous goods in Canada is trained and holds a certificate, and further changes to Part 6 on training have been signalled by Transport Canada for future consultation. Chinese exporters are not directly bound by Canadian certification for the work they do in China, but they are bound by the equivalent Chinese and IMDG training requirements, and their Canadian partners will want proof of competence.
How Topway Shipping Supports Dangerous Goods Shipments to Canada
Since 2010, Topway Shipping, headquartered in Shenzhen, China, has been a professional provider of cross-border e-commerce logistics solutions. The founding team has more than 15 years of experience in international logistics and customs clearance, with a strong focus on China–U.S. transportation. That background matters for Canadian dangerous goods because the same disciplines apply on both lanes: tight document control, realistic carrier acceptance checks and clear communication with the party who will clear the goods at the other end.
Topway Shipping covers the entire logistics chain, including first-leg transportation, overseas warehousing, customs clearance and last-mile delivery. The company also offers flexible full-container-load and less-than-container-load ocean freight services from China to major ports worldwide, which gives shippers of regulated cargo a choice between a dedicated container and a consolidated service depending on volume, class and timing. For dangerous goods, the practical advantage of an integrated provider is that classification questions, packing instructions, booking and Canadian delivery planning are handled by one team rather than passed between several companies.
If you are planning a first shipment of aerosols, adhesives, cleaning products, lithium battery products or similar goods to Canada, contact Topway Shipping before you finalize packaging and cartons. Sending the SDS, product photos and intended quantities up front lets the team review the likely classification, check which service can accept the cargo and identify documents that your Canadian importer needs to prepare. Finding a problem at that stage costs almost nothing compared with finding it at the terminal.
Conclusion
Shipping dangerous goods from China to Canada is neither mysterious nor impossible. It rewards exporters who treat compliance as a process and punishes those who treat it as paperwork to be fixed at the last minute. Classification must come first, UN-certified packaging and correct marks next, and consistent documents throughout, with an ERAP and an emergency number in place where the goods require them.
The 2026 amendments, published on June 17, 2026, make the Canadian rules friendlier to shippers who already follow international standards. They simplify the lithium battery mark, relax formatting and language requirements, tighten how the limited quantity mark is placed, update packaging standards and modernize the air rules in Part 12. The detailed coming-into-force dates, including the transition period, should be confirmed with your Canadian importer and forwarder for each sailing.
Above all, remember that responsibility is shared. The Chinese shipper, the forwarder, the carrier and the Canadian importer each hold a piece of the compliance chain, and the strongest chains are the ones where everyone talks early. Choose a forwarder that asks the hard questions before the booking rather than after the container is on the water.
FAQs
Q: Does a Chinese exporter need to follow the TDG Regulations directly?
A: The TDGR apply to dangerous goods handled, offered for transport or transported in Canada, and the Canadian importer usually carries the consignor duties for the inland leg. The Chinese exporter must still classify, package, mark and declare the goods correctly under Chinese rules and the IMDG Code or IATA regulations, and should supply the data that the Canadian side needs.
Q: Can I ship lithium batteries to Canada by sea?
A: Yes, subject to the IMDG Code, the UN 38.3 test summary and the carrier’s own policy. Many carriers and LCL consolidators restrict or specially approve lithium batteries, so confirm acceptance before packing.
Q: Are the 2026 TDG changes already mandatory?
A: The amendments were published on June 17, 2026, and a transition period applies during which either the old or new rules can generally be followed. Industry guidance cites June 2027 for key changes, so confirm the specific provisions and dates with your importer or forwarder.
Q: When is an ERAP required?
A: When the UN number and quantity exceed the thresholds in the ERAP index of Schedule 1 of the TDG Regulations. It is usually the consignor in Canada who arranges it, so raise the question with your buyer before booking.
Q: Do I need bilingual labels?
A: Under the revised rules the required words on TDG labels and placards may be in English or French. Consumer product labelling and the workplace SDS rules in Canada are separate and may require both languages.
