Understanding HS Codes and Tariffs for China Imports at Port of Portland
Introduction
If you are bringing goods into the US from China through the Port of Portland, you need to know Harmonized System (HS) codes and the tiered tariff system that applies to Chinese commodities. This is no longer optional; it is necessary to be lucrative and legal. Since 2018, trade between the US and China has changed a lot. In 2025, things became even worse: tariff rates shot up to an all-time high of 145% before going back down after a deal was made in November 2025.
At the same time, the Port of Portland has changed a lot. Since January 2026, California-based Harbor Industrial Services has been in charge of Terminal 6, which is now called the Oregon Container Terminal (OCT). The state of Oregon put $20 million into the project. This change has made container operations stable again, which were about to close for good. It has also given importers who depend on this Pacific Northwest gateway fresh confidence.
This guide will teach you everything you need to know about HS codes, how tariffs work, what changed in 2025, and how to protect your margins through smart classification and compliance strategy. It doesn’t matter if you’re a seasoned importer or a new business bringing goods from Chinese suppliers for the first time.
What Is an HS Code and Why Does It Matter?
The World Customs Organization (WCO) runs the Harmonized System (HS), which is a system for classifying commodities that are traded around the world. It gives every product, from soybeans to transistors, a number code and is the language of world trade. When your products get to the Port of Portland, U.S. Customs and Border Protection (CBP) utilizes the Harmonized Tariff Schedule of the United States (HTSUS), which is the U.S. version of this system, to figure out how much duty you owe.
There are ten digits in HTSUS codes. The first six characters are the same as the international HS code used by China and most other countries. The latter four digits are only for the United States and tell you the exact duty rate, quota treatment, and statistical reporting category for your product. This difference is more important than most importers think: a Chinese supplier may provide a 6-digit HS code on their export papers, but when you file your entry with U.S. customs, they need a complete 10-digit classification.
Getting the code properly isn’t just a matter of filling out forms. The HTSUS code you declare sets your base Most Favored Nation (MFN) duty rate, tells you if Section 301 tariffs apply and at what rate, if any anti-dumping or countervailing duty orders are in effect, and if your product is being investigated for trade remedies or import restrictions. If you misclassify something, even if you didn’t mean to, you could get a fine from CBP that is up to four times the amount of duty you didn’t pay. CBP also has the power to look into your import history for the prior five years.
How the 10-Digit HTSUS Code Is Structured
| Digits | What It Represents | Example (Cotton T-Shirt) |
| 1–2 | Chapter (broad product category) | 61 (Knitted apparel) |
| 3–4 | Heading (product family) | 6109 (T-shirts, singlets) |
| 5–6 | Subheading (material/type) | 610910 (Of cotton) |
| 7–8 | U.S. heading (further specification) | 61091000 |
| 9–10 | Statistical suffix (U.S. only) | 6109100020 |
The Tariff Stack: How Duties Layer on Chinese Goods
One of the most expensive mistakes importers make is thinking that their product has only one tariff rate. In actuality, Chinese goods that come into the United States, even through the Port of Portland, have to pay a lot of different taxes. The primary tariff layers will look like this in early 2026, after the Kuala Lumpur Joint Arrangement between the U.S. and China in November 2025.
Layer 1: MFN Base Rate
This is the regular duty rate for goods coming into the US from nations that have normal commercial ties with the US. It varies a lot by product, from 0% on various industrial inputs to more than 37% on some types of clothing. The HTSUS sets this as your starting point.
Layer 2: Section 301 Tariffs
These duties, which started in 2018 under Section 301 of the Trade Act of 1974, are meant to stop unfair activities connected to technology transfer and intellectual property. They only apply to goods coming from China. The rates are either 7.5% or 25%, depending on the goods. Most categories were given an extension until November 2026 after the Trump-Xi agreement in November 2025. As part of that deal, 178 product exclusions were renewed. This means that it’s important to verify to see if any exclusion applies to your individual HTSUS category.
Layer 3: IEEPA Fentanyl Tariff
The Trump administration put an extra tariff on all Chinese imports in February 2025. They did this because China had not stopped suppliers of fentanyl precursors. As part of talks between the two countries, this tax started at 10%, went up to 20% for a short time, and then went back down to 10% on November 10, 2025. It should stay at 10% until at least November 2026, unless the president takes action.
Layer 4: IEEPA Reciprocal Tariff
As part of the larger U.S.-China trade pressure campaign, a separate reciprocal tariff was put in place. At its highest point in the middle of 2025, the combined IEEPA-based taxes made the effective rate on Chinese goods reach an all-time high of 145%. The November 2025 agreement keeps the 10% baseline IEEPA reciprocal tariff in place, on top of the MFN and Section 301 tariffs.
Layer 5: Anti-Dumping and Countervailing Duties (AD/CVD)
CBP also collects AD/CVD fees on several types of products, like solar panels, steel, furniture parts, tires, seafood, and more. These can be very high, sometimes more than 300% of the declared value. AD/CVD rates can be changed after the fact, which means you could get an extra bill months after your products cleared customs. This is different from other charges that are charged up front. The customs broker or Chinese supplier is not totally responsible; the importer of record is.
Estimated Total Tariff Rate for Common Chinese Product Categories (Early 2026)
| Product Category | MFN Rate | Section 301 | IEEPA (Combined ~20%) | Estimated Total |
| Consumer Electronics | 0% | 7.5%–25% | ~20% | 27.5%–45%+ |
| Apparel & Footwear | 12%–37% | 7.5%–15% | ~20% | 39.5%–72%+ |
| Furniture | 0%–9.5% | 25% | ~20% | 45%–54.5% |
| Machinery & Equipment | 0%–3.9% | 7.5%–25% | ~20% | 27.5%–48.9% |
| Steel Products | 0%–15% + Sec. 232 (25%) | 25% | ~20% | 70%+ (excl. AD/CVD) |
| Plastic Goods | 3.4%–6.5% | 25% | ~20% | 48.4%–51.5% |
| Toys & Games | 0% | 0%–7.5% | ~20% | 20%–27.5% |
Note: These ranges are merely meant to show you what they are. The actual rates depend on the 10-digit HTS code, any restrictions that apply, and any AD/CVD orders. Always check with a licensed U.S. customs broker.
The End of De Minimis: A Fundamental Change for Small-Value Shipments
Importers and e-commerce enterprises had a big advantage until 2025. Under the de minimis clause (19 U.S.C. 1321), shipments worth $800 or less could enter the U.S. without paying any taxes. This exemption was especially useful for enterprises who shipped tiny packages directly to customers from China.
That time is now over. The de minimis exemption for all commodities coming from China, Hong Kong, and Macau ended on May 2, 2025. The U.S. stopped de minimis for all countries on August 29, 2025. Now, every shipment from China, no matter how much it costs, needs to go through formal entry processing and pay the full tariff stack. This is a structural change that requires businesses who rely on de minimis treatment to completely rethink how they set prices, find suppliers, and handle logistics.
Importers transporting products through the Port of Portland must now pay complete documentation, customs bonds, and duty on even modest LCL consolidation shipments that used to be able to avoid these procedures. The cost of compliance each entry is pretty much the same no matter how much the shipment is worth, therefore extremely small shipments may have to pay more than their fair share. Companies who used to send five or ten tiny items a week now have to decide if it makes more sense to send all of their packages at once every month.
How to Classify Your Products Correctly
There is both art and science in classifying products. There are more than 17,000 different line items in the HTSUS. For a lot of products, especially those that employ more than one type of material or have more than one use case, finding the right 10-digit code can be very hard. The Binding Ruling Program from CBP helps importers figure out what HS code their product should have. Importers can make a formal request for a legally binding decision on the right HS code for their product.
It takes about 30 days and costs nothing to get a binding ruling. You can use it for customs reasons until CBP changes or cancels it. This is one of the greatest ways to make sure you’re following the rules, especially for items from China where misclassification can lead to Section 301 tariff responsibility on top of the charge. This is especially true for high-volume import programs or products that aren’t clear on their categorization.
The General Rules of Interpretation (GRIs) tell us how to sort out products that aren’t clear. Section, chapter, and heading notes are the first things that GRI 1 uses to decide classification. GRI 3 talks about composite goods. It says that specific trumps general, essential character wins for mixtures, and if all else fails, the highest tariff code number applies. The main thing that most importers should remember is to never guess. Hire a registered customs broker that knows a lot about your type of goods, write down why you classified it the way you did, and review it every time your product specs change.
Key Documentation for China Imports at Port of Portland
In addition to having your HTSUS code and the correct tariff rate, you also need to have a full and consistent set of import documentation in order to get through customs at the Port of Portland. If there is any difference between the documents, even a small one in weight or product description, customs may hold or examine them. This can lead to demurrage and examination fees that quickly eat away at your profits.
| Document | Purpose | Key Risk to Avoid |
| Commercial Invoice | Declares product, value, buyer/seller, Incoterms | Vague descriptions, undervalued prices, wrong currency |
| Packing List | Details quantity, weight, dimensions per carton | Mismatch with invoice quantities or weights |
| Bill of Lading (OBL) | Proof of contract with ocean carrier | Wrong consignee name, incorrect container number |
| Importer Security Filing (ISF) | 10+2 filing, must be submitted 24 hrs before vessel loading | Late filing = $5,000 CBP penalty per violation |
| Country of Origin Declaration | Confirms goods are product of China | Missing for UFLPA compliance documentation |
| Customs Bond (CBP Form 301) | Guarantees duty payment to U.S. government | Wrong bond amount; single entry vs. continuous |
| Entry Summary (CBP Form 7501) | Filed by broker to declare and pay duties | Wrong HTS code, incorrect valuation method |
The ISF Filing: A Critical Pre-Departure Requirement
Your customs broker must send the Importer Security file (ISF), also known as the 10+2 file, to CBP using the Automated Commercial Environment (ACE) system at least 24 hours before the cargo is loaded onto the ship at the Chinese port of origin. It has 10 pieces of information from the importer, such as the buyer and seller, the ship-to party, the place where the container is stuffed, and the HTSUS code. It also has 2 pieces of information from the ocean carrier. If you file your ISF late or incorrectly, you will be fined $5,000 for each infraction, even if there are no other compliance issues. This is one of the most typical compliance blunders that people make while moving from China to the U.S. ocean freight.
UFLPA Compliance: Supply Chain Transparency Is Now Table Stakes
The Uyghur Forced Labor Prevention Act (UFLPA) has made it much harder for China to import goods from 2022. UFLPA makes it illegal to import items into the U.S. under 19 U.S.C. 1307 if they were mined, produced, or made in whole or in part in Xinjiang or by companies on the UFLPA Entity List.
In 2025, UFLPA enforcement went far beyond items created in Xinjiang. If your product’s parts, raw ingredients, or precursor inputs include Xinjiang-sourced cotton, polysilicon, aluminum, certain steel grades, tomatoes, or other protected agricultural goods, CBP can hold your shipment even if the final goods were put together in another part of China. For businesses who import textiles, electronics, solar items, and a growing number of industrial commodities, supply chain traceability is becoming a must-have.
Importers who are put on a UFLPA hold must show clear and persuasive proof—usually factory audits, certifications of where they get their raw materials, third-party supply chain mapping, and transaction records—to get their shipment released. The costs of a UFLPA hold, such as bonded warehouse storage, legal fees, and the possibility of losing the cargo, might potentially be more than the value of the items itself. It costs a lot less to build traceability into your sourcing process before you place an order than it does to try to do so after a hold.

Port of Portland in 2025–2026: What Importers Need to Know
The container port at the Port of Portland has had a lot of problems in the past few years, but things are looking better as we head into 2026 than they have in almost ten years. Starting January 16, 2026, Terminal 6, which is now called the Oregon Container Terminal and is run by Harbor Industrial Services, will be open five days a week instead of four. The terminal now has direct container routes from China and South Korea, with MSC and SM Line being the main carriers.
The U.S.-China tariff truce in May 2025, which temporarily lowered IEEPA rates from 145% to 30% for 90 days of talks, had a big impact on the amount of goods coming into Portland. Before the announcement, the port had predicted that container arrivals would drop by 30%. This shows how trade policy may directly affect the amount of cargo that comes into a regional port. For importers, this shows how important it is to include scenario-based tariff planning in their buying decisions instead of just assuming that current rates would stay the same.
New USTR port taxes on ships built in China or owned or operated by Chinese people went into effect on October 14, 2025. About 25% of direct China–West Coast services have been redirected through hubs like Busan or Singapore to avoid the extra cost. Importers should check with their freight forwarder to find out which ships will carry their goods and whether any changes to the route will effect how long it takes to get to Portland.
| Port of Portland Fast Facts (Early 2026) | Details |
| Terminal Operator | Harbor Industrial Services (since Jan 2026), 7-year lease |
| Weekly Operating Days | 5 days (expanded from 4 as of Jan 16, 2026) |
| Active Carriers on China Route | MSC, SM Line |
| Typical Ocean Transit (Shanghai → Portland) | 15–18 days |
| Typical Door-to-Door (China → Oregon) | 22–30 days under normal conditions |
| Additional Time if Exam Selected | +5–10 business days |
| De Minimis for China Origin | Eliminated as of May 2, 2025 |
| Chinese Vessel Port Fees | Active since Oct 14, 2025; affects some route schedules |
Practical Tips to Minimize Your Tariff Burden and Classification Risk
There is no legal way to avoid paying tariffs, but there are legal and very effective techniques to lower your risk and avoid paying extra fines.
Before you start importing a lot of a new type of product, you should first get a CBP Binding Ruling. A binding ruling clears up any confusion about your categorization and gives you a legal argument if CBP later questions your code. It doesn’t cost anything, takes about 30 days, and is especially useful for things that are complicated or made of more than one material. This process is basically required for electronics assembly, hybrid items, or machines that have software built in.
Second, do a thorough Section 301 exclusion check on all of your products. Even in early 2026, there are still current exceptions for several HTSUS subheadings. These can lower or get rid of the 25% Section 301 surcharge. The Trump-Xi deal in November 2025 added 178 product-specific exclusions that will last until November 2026. Your customs broker should do this check before a shipment is on its way, not just when it is.
Third, look into First Sale Valuation if your supply chain includes a Chinese trading company or middleman. Instead of the amount that the U.S. importer pays their Chinese agent, first sale value looks at the price of the transaction at the factory level. This can lower your dutiable value by a lot for things with big markups in the middle, which means you’ll pay less in duties overall. To do this, you need to keep good records of the factory-level sale. But for importers who bring in a lot of goods, the savings can be considerable each year.
Finally, make sure to register your customs entry before the ship arrives. You can file with CBP up to five days before the ship gets to Portland. If you file before you arrive, your entry will be checked while the ship is still at sea. If it is accepted, the cargo can be released within hours of docking. This one operational approach can cut terminal dwell time by two to four days and greatly lower the danger of demurrage.
Conclusion
In 2025 and 2026, when you import goods from China through the Port of Portland, you need to know a lot about customs and tariffs that you didn’t five years ago. The new tariff structure, which includes MFN rates, Section 301 surcharges, IEEPA tariffs, and possible AD/CVD charges all stacking on top of each other, as well as the end of de minimis treatment, the expansion of UFLPA enforcement, and changes at Terminal 6, mean that compliance is now a core operational competency, not just something that happens in the back office.
If you want to move goods from China to the U.S. market in a way that is both environmentally friendly and profitable, you need to know your HTSUS code inside and out, know which tariff layers apply, set up a documentation process that CBP is happy with on the first review, and work with experienced logistics partners.

Frequently Asked Questions (FAQs)
Q: What is the difference between an HS code and an HTS code?
A: The Harmonized System (HS) code is a 6-digit code that most countries use to classify products. The Harmonized Tariff Schedule (HTS) code is the U.S. version, which has 10 digits. You need to utilize the complete 10-digit HTS code when bringing anything into the United States. China has a 13-digit categorization system for its exports. This is why you should always check codes with a U.S.-licensed customs broker before filing for entry.
Q: How do I find the correct HTS code for my product from China?
A: You can look up the HTSUS at hts.usitc.gov, but if you’re bringing in a lot of goods for business, it’s best to work with a licensed U.S. customs broker. If you have a product that is worth a lot of money or is hard to understand, you might want to ask CBP for a Binding Ruling. It’s free, legally binding, and you should get it in around 30 days.
Q: What is the total tariff rate on Chinese goods entering Portland in 2026?
A: It depends on the HTS code you have. Most Chinese imports have to pay at least three different taxes: the MFN base rate, Section 301 tariffs (7.5% or 25%), and IEEPA charges of about 20% that are added together. For several types of products, the total effective rates are higher than 40%–55%, and for some items with AD/CVD orders, the rates are even higher than 100%. Before making a sourcing decision, always figure out your whole landed cost.
Q: Can I still ship small parcels from China to Portland duty-free?
A: No. On May 2, 2025, the $800 de minimis exemption for goods from China was taken away. All goods from China, no matter how much they cost, now need to go through customs and pay the right taxes. On August 29, 2025, the de minimis exemption for commodities from all other countries was similarly put on hold.
Q: What happens if my product is detained under UFLPA?
A: CBP will send you a notice of detention, and you will have a chance to show that your supply chain does not involve forced labor from Xinjiang with clear and convincing proof. This usually means checking the factory, keeping records of where raw materials come from, and getting third-party supply chain documents. The things may not be allowed in if there isn’t enough proof. It’s much better to work with a logistics partner like Topway Shipping that focuses on compliance before shipping than to deal with a UFLPA hold after the fact.
Q: How can Topway Shipping support my China-to-Portland import program?
A: Topway Shipping provides full logistics support, including FCL and LCL ocean freight from major Chinese ports to Portland, the initial leg of transportation in China, customs clearance coordination, foreign warehousing, and delivery in the U.S. Topway was founded in 2010 and is based in Shenzhen. Its team has more than 15 years of experience working between China and the U.S. They have experience with logistics and can assist you pre-classify products, organize paperwork appropriately, figure out the real landing cost, and handle the whole import procedure from the manufacturer to the Oregon warehouse.
