Section 301 + 232 + IEEPA: How to Stack Your Real Landed Cost Before You Quote a Customer
Introduction
If you are quoting a customer on enormous cargo coming from China to the United States or Europe in 2026 and you have not previously computed the whole tariff stack before you send that amount, you are pricing in the dark. The preceding 18 months have resulted in one of the most radical rewrites of U.S. trade law in a generation. Section 301, Section 232, and the partially knocked down IEEPA reciprocal framework each introduced their own independent layer of costs to China-origin imports—they did not replace each other. They build up, they add on to the same shipment, the same HTS code, the same container.
The figures aren’t academic for importers and logistics buyers working with large products – furniture, appliances, workout equipment, industrial machinery, massage chairs, treadmills. A sofa set that seemed like a bargain at FOB Guangdong could arrive at a U.S. port with an effective duty burden of more than fifty percent of the declared value, and a supplier offering suspiciously cheap DDP terms may simply be undervaluing the shipment at customs; this makes the buyer liable for fraud he did not commit. Not only is following this stacking process a compliance issue. That’s a commercial survival skill.
The Three Tariff Authorities and What Each One Does
Section 301 of the Trade Act of 1974 authorizes the U.S. Trade Representative’s authority to levy retaliatory tariffs when a trading partner is deemed to be engaged in unfair trade practices. Under this jurisdiction, China was targeted beginning in 2018, and four lists of targeted commodities were issued with a combined annual import value of hundreds of billions of dollars. The majority of the items originating in China will be subject to Section 301 charges of 7.5 percent or 25 percent by early 2026, depending on which list their HTS code is on. After USTR’s mandated four-year review in 2024, some critical categories earned big rate increases: 100 percent for electric vehicles, 50 percent for solar cells and 25 percent for lithium batteries.
232 of the commerce Expansion Act of 1962 is predicated on somewhat different basis, one that is based on national security rather than unfair commerce. In 2025, Section 232, which was first used in 2018 to impose 25 percent tariffs on steel imports and 10 percent tariffs on aluminum imports, was greatly enlarged. Steel prices increased to 50 percent, all country level exclusions were removed and 407 derivative product codes placed into its ambit. This is significant for oversized cargo shippers because many large consumer goods — appliances, exercise equipment, metal-framed furniture — contain enough steel or aluminum that the derivative product rules can bring the finished product under Section 232 coverage as well as any Section 301 rate that is already in place.
The foundation for the extensive reciprocal tariff structure revealed in April 2025, which set a baseline 10 percent rate on imports from nearly every country and higher rates on some trading partners, was the IEEPA – International Emergency Economic Powers Act. On February 20, 2026, the Supreme Court ruled 6-3 to strike down the IEEPA tariffs, saying the Act does not permit the president to apply tariffs. The court voided some $160 billion in duties collected. But the administration replied with replacement procedures under Section 122 of the Trade Act, which temporarily imposes emergency balance-of-payments tariffs on certain trade flows at roughly 10 percent. The legal situation remains fluid and importers who paid IEEPA charges between April 2025 and the February 2026 ruling may be able to seek refunds from CBP — but statute of limitations deadlines necessitate swift action.
How Stacking Actually Works: The Layer Cake of Duties
Cumulative is the operative word in every landing cost computation. CBP does not choose one tariff authority and apply it, but applies all applicable authorities concurrently, each computed against the customs value of the items. Some fees are capped and some are not, therefore the order in which you do the calculations counts.
Start with the base MFN duty rate, the rate you see in the HTSUS for your 10-digit HTS code. This can be anything from zero on various devices to 37.5 per cent on some textiles. If your items are of Chinese origin and are on any of the active listings, add Section 301. If your items are steel, aluminum, or copper, review Section 232 derivative product coverage. Then, if your HTS code is currently covered by Section 122, include that also. Then compute the Merchandise Processing Fee, 0.3464 percent of the customs value, with a minimum of $31.67 and a maximum of $634.62 per entry. maritime shipping, add the Harbor Maintenance Fee of .125 percent. If you have a specific product and manufacturer covered by active antidumping and countervailing orders, the duties stack on top of all of that .
Thus, the actual duty rate on goods originating in China in 2026 bears virtually little relation to what a casual glance at the MFN column of the HTSUS would indicate. The table below shows how this stacking works across product categories typical in large freight.
| Product Category | HTS Example | MFN Base | Section 301 | Section 232 | Approx. Total Duty |
| Upholstered sofa (China) | 9401.61 | 0% | 25% (List 3) | N/A | ~25% |
| Treadmill / fitness equipment | 9506.91 | 3.7% | 7.5% (List 4A) | N/A | ~11.2% |
| Steel-framed bookcase | 9403.20 | 0% | 25% (List 3) | 50% (232 derivative) | ~75% |
| Washing machine (large) | 8450.20 | 1% | 25% (List 3) | N/A | ~26% |
| Massage chair | 9402.90 | 0% | 7.5% (List 4A) | N/A | ~7.5% |
| Electric scooter | 8711.60 | 0% | 25% (List 3) | N/A | ~25% |
| Aluminum outdoor furniture | 9401.79 | 5.3% | 25% (List 3) | 25%+ (232 alum.) | ~55%+ |
| Range hood / kitchen appliance | 8414.60 | 1.4% | 25% (List 3) | N/A | ~26.4% |
Note: Rates are estimated and for illustration purposes based on publicly accessible data as of June 2026. Verify precise HTS classification and relevant Chapter 99 overlays with a licensed customs broker before quoting. Totals do not include Section 122 surcharges and MPF/HMF costs.
The Oversized Freight Dimension: Why Large Items Face Greater Exposure
Oversized cargo, which refers to commodities that exceed regular parcel limits, generally over 150 kilos or with a longest edge over four meters, bears compounding risk in tariff stacking for reasons that extend beyond simple rate calculations. First, large items are disproportionately concentrated in the product categories most heavily targeted by section 301; Furniture, household appliances, fitness equipment and industrial machinery make up a large part of China’s outsized cross-border shipments, and these fall clearly within Lists 3 and 4A. Second, the customs value tends to be high per shipment for big products even if the per-unit margin is thin, so that tiny percentage variances in effective duty rate translate into huge absolute dollar amounts.
Third, the actual handling of big freight is difficult, making it more likely that categorization errors may occur. A sofa that comes in five boxes can be categorized differently from a sofa that is already built. A treadmill’s motor and frame may be transported disassembled to save on costs, in which case they may fall under various HTS codes with varied Section 301 exposure. Every misclassified commodity means the estimate of landed costs is off by a factor, and if in the seller’s favor then the buyer pays for the difference at the port.
Fourth, big freight by definition requires last mile delivery services beyond conventional small parcel drop-off: appointment scheduling, liftgate service, room-of-choice placement, assembly and debris cleanup. Those charges are actual and material and they ought to be inside the landed cost amount before any quote is sent to a customer.
Building the Real Landed Cost: A Step-by-Step Framework
The goal is one number that reflects the real cost of taking the items from the manufacturing floor to the customer’s hand, including all the fees, duties and handling charges that will be invoiced along the route. Go through these elements in succession.
Step 1: Establish the Correct HTS Classification
The whole tariff stack rests on getting this right. Do not rely on HTS codes provided by suppliers without independent verification. Suppliers have an incentive to understate rates and misclassification generates CBP liability for the importer. Use the USITC HTSUS database. Cross-check with published Section 301 product listings accessible from USTR. Verify Section 232 derivative coverage through the appropriate Federal Register announcements. Legal assurance for complex items through a binding ruling request from CBP.
Step 2: Calculate the Full Duty Stack
Apply each tariff layer in sequence to the transaction value (usually the price you paid for the items, in USD, including aids, if applicable). Section 301. Increase MFN base tariff rate. Review Section 232 derivative product coverage and include if applicable. Add if appropriate . Check current Section 122 applicability . Add all relevant rates and apply to transaction value Run MPF separately at 0.3464 percent, check against floor, check against cap. If the shipment is moving by ocean, run HMF.
Step 3: Add All Freight and Accessorial Charges
This is more significant for big cargo than for ordinary freight. The table below illustrates a realistic cost structure for a China-to-U.S. large shipment and the significant impact that freight associated charges might have on the final landing cost.
| Cost Component | Typical Range | Notes |
| Factory gate price (FOB China) | Varies by product | Base for duty calculation |
| Origin handling & crating | $80 – $350 per piece | Higher for fragile or bulky items |
| Ocean freight (LCL/FCL) | $150 – $600 per CBM | Rate-volatile; lock in early |
| Destination port handling | $200 – $500 per consignment | THC, PCS, ISF |
| Customs brokerage | $150 – $350 per entry | More for complex multi-HTS shipments |
| Customs duties (stacked) | See rate table above | Calculated on transaction value |
| MPF | 0.3464%, capped at $634.62 | Per entry, not per piece |
| HMF (ocean only) | 0.125% of dutiable value | Applied to ocean shipments |
| Drayage (port to warehouse) | $300 – $800 per load | Distance and equipment dependent |
| Last-mile oversized delivery | $150 – $500 per piece | Appointment + liftgate + placement |
| Assembly and debris removal | $75 – $200 per piece | Customer-facing expectation |
Step 4: Apply Insurance and Add Contingency
Cargo insurance cost for large products is usually 0.3 to 0.8 percent of the declared cargo value. Given the physical handling difficulty of products such as massage chairs, treadmills and large appliances, the upper end of this range is reasonable. Also, include a contingency buffer of 3 to 5 percent in each quote to cover tariff rate variations, currency moves, accessorial charges that arise at delivery and re-delivery expenses if the consignee misses their appointment window.
The De Minimis Elimination and What It Means for Your Supply Chain
One of the biggest structural changes in the trading environment in 2025 to 2026 has been the removal of de minimis treatment for goods of China and Hong Kong origin. As of May 2025, shipments worth at or less $800 may enter the United States duty-free under the de minimis clause. Originally this provision was deleted for China and Hong Kong, and then withdrawn more generally from February 24, 2026 so that now all shipments are subject to formal entry regardless of value.
Oversized freight carriers are not as dramatically affected as small package direct-to-consumer shippers, since oversized goods rarely qualified for de minimis to begin with. But the shift is causing rippling effects through the logistics ecosystem: customs brokers are processing much greater entry volumes, clearance times are stretching and bonded warehouse operations are under stress. Allow a little extra time for clearances and verify your customs broker is adequately staffed and has appropriate system capacity.
DDP Traps: Why Low Supplier Pricing Can Be Customs Fraud
In a situation where effective duty rates on Chinese-origin goods can be more than 50 percent, some suppliers have responded to client demand for landed cost certainty by offering DDP terms at prices that seem to ignore the arithmetic. The method is generally customs undervaluation, where the supplier reports a lower customs value to CBP than the real transaction price, decreasing the duty base. “That’s fraud. The importer of record, not the supplier, is legally exposed.”
Since 2023, CBP has increased its inspection of shipments of big items from China and identifies undervalued entries through transaction value databases, comparisons to market prices, and analysis of related-party transactions. A $2,000 massage chair from a Chinese source would have DDP duties of $150 although the correct duty rate should be $600.That disparity is the deception. For careless violations, penalties under 19 U.S.C. 1592 can amount to four times the unpaid duties, and for fraudulent offenses, they can be much higher.
The correct way is to utilize CIF or CPT terms, secure a fully recorded commercial invoice representing the true transaction value, and have your licensed customs broker file the entry on accurate figures. The duties are what they are. Hiding them creates a liability that makes the original cost reduction meaningless.

Topway Shipping is a competent cross-border e-commerce logistics solutions provider in Shenzhen, China since 2010. The founding team boasts over 15 years of experience in international logistics and customs clearance, particularly China to US. and China to Europe transport for the large and heavy-cargo segments.
Topway is one of the few logistics companies that has built its whole service infrastructure around what it terms the super-large item segment: single items that can weigh as much as 8 metric tons, with the longest edge up to 8 meters and height below 2.57 meters. This includes the whole gamut of product types most affected by the tariff stacking explored in this article – sofas, treadmills, massage chairs, washing machines, refrigerators, electric vehicles, commercial kitchen equipment, mahjong tables and industrial machinery – categories where misquoting the landed cost has immediate commercial ramifications.
We offer a full range of services along the whole logistic chain. Topway has consolidation warehouses in Shenzhen that are recorded for large-format crating and cargo loading. It offers direct ocean freight services on reliable routes to key U.S. and European ports, and China-Europe rail freight via the China-Europe Express Train network, with transit periods of 30 to 45 days and scheduled departure schedules on a daily or weekly basis. Air freight is used for high value seasonal products where the 12 to 15 day transit duration makes the additional cost worthwhile. The company also provides customizable FCL and LCL agreements for both large and small volume shippers, enabling it to be accessible to cross-border sellers across the volume spectrum.
Overseas warehouse provides B2B and B2C last mile delivery with full appointment scheduling, liftgate service and room-of-choice placement, with locations in the U.S. and Europe.

Legitimate Ways to Reduce Your Tariff Stack
The first and most important lever is diversification by country of origin. Section 301 applies only to products made in China. Moving manufacture to Vietnam, India, Thailand or Mexico gets rid of the Section 301 surcharge totally if the product is truly made there. CBP keeps a tight eye on transshipments. Shipping Chinese made items through a third nation without major alteration does not alter the origin or lower the tariffs. Manufacturing change has to be real.
The second lever is the correct classification of HTS. Tariff rates can vary widely from one HTS code to another, and even slight but reasonable changes to a product – changing a material, adding a component, changing assembly sequence – can move a product into a classification with lower Section 301 exposure. This is not an evasion, it is product design. But legally and ethically it is important . The product has to actually qualify for the new classification .
Third, look at the active Section 301 exceptions and see whether any apply to your unique HTS code. These exclusions are product specific, restrictive and time limited although a small number are still in force. USTR has a process for exclusion requests for products that are not available from domestic or non-China sources. Fourth, for items comprising steel and aluminum, confirm whether Section 232 derivative product coverage actually applies to your final good. The derivative product restrictions are cumbersome and there are products with metal that are not covered under Section 232.
Finally, if you paid IEEPA tariffs from April 2025 through the February 2026 Supreme Court verdict, contact a licensed customs broker today about the filing of a refund claim through a Post Summary Correction. The statute of limitations is running on these cases and the amounts at stake for big volume importers might be substantial.
Conclusion
The U.S. tariff landscape in 2026 will not be a momentary interruption that will normalize once trade discussions are concluded. The section 301 tariffs on Chinese imports are baked into supply chain choices and unlikely to be rolled back. Section 232 has been enlarged and strengthened. Instead, Section 122 is in effect as a substitute for the IEEPA framework thrown down. It is not an aberration that various authorities stack on the same items. It is a fundamental element of the existing trading environment.
For every seller, logistics buyer, customs broker or e-commerce operator dealing with enormous cross-border freight, the only appropriate action is to assess the total landing cost before any pricing is quoted. That requires understanding the exact HTS code, identifying each tariff layer that applies, factoring in true freight and last-mile costs for the product category and building in sufficient buffers for regulatory volatility.
The winners in this context are those that have made landed cost accuracy a key operational capability, not an afterthought. A competitive edge, and increasingly, a baseline requirement for successful cross-border commerce, is partnering with a logistics provider who knows the mechanics of freight and the duty stack for big items.
FAQs
Q: Can Section 301, Section 232, and Section 122 all apply to the same shipment at the same time?
A: Yeah. These tariff authority are autonomous and cumulative. A steel-framed piece of furniture from China can be subject to MFN base duty, a Section 301 overlay, a Section 232 derivative product surcharge and a Section 122 reciprocal surcharge, all at the same time. They are calculated separately on the customs value and summed up.
Q: Did the Supreme Court ruling eliminate all additional tariffs on China imports?
A: Nope. That verdict in February 2026 expressly nullified tariffs based on IEEPA. Section 301 tariffs are still in full force. Tariffs on steel, aluminum under Section 232 still in force. The administration has created Section 122 as a separate process for some of the reciprocal tariff functions. Importers should consult with CBP advice and a registered broker to determine current applicability to specific HTS codes.
Q: How do I handle a supplier offering DDP pricing that seems too low given current tariff rates?
A: Ask for complete documentation of the calculation of the duty, including the HTS code used, the customs value declared and the entry number if the items have previously been imported. If the math doesn’t work out at legal duty rates, the supplier is probably undervaluing the package at customs. The ultimate customer (you) should not be put at risk of liability for someone else’s misrepresentation to CBP.
Q: Is there a way to estimate landed cost without hiring a customs broker?
A: Some online tariff calculators now include Section 301, Section 232, and current surcharge stacking for certain HTS codes. But these instruments estimate, they don’t make legal determinations.” Before moving any cargo with substantial commercial value, the classification and overlaying should be verified by a professional customs broker.
Q: What types of oversized products does Topway Shipping handle?
A: Topway is involved in goods up to 8 metric tons per piece and up to 8 meters on the longest edge including sofas, massage chairs, treadmills, refrigerators, washing machines, dishwashers, electric vehicles, mahjong tables, industrial machinery, street lighting equipment, commercial printers and a wide range of home and business equipment. Supports B2B and B2C last-mile delivery in the U.S. and 25 EU nations.
