Section 301 Tariffs Explained: What Importers Need to Know in 2026

Quick answer

Section 301 tariffs are extra duties the U.S. Trade Representative imposes on goods from countries found to engage in unfair trade practices. Chinese goods carry the original list rates of 7.5% to 25%, with some products at 50% or 100%. Since July 2026, a 12.5% forced-labor tariff stacks on top.

Key takeaways

• Section 301 of the Trade Act of 1974 lets the U.S. Trade Representative impose tariffs in response to unfair foreign trade practices. It began with China in 2018.
• Chinese goods on Lists 1, 2, and 3 generally pay 25%, List 4A goods pay 7.5%, and List 4B was never imposed.
• The 2024 four-year review raised rates on strategic goods, including electric vehicles to 100% and solar cells and semiconductors to 50%, phased in through 2026.
• Since July 24, 2026, a separate forced-labor Section 301 tariff adds 12.5% on most Chinese goods, on top of the original lists, and 10% or 12.5% on 59 other economies.
• The importer of record pays Section 301 duties at entry, calculated on the goods' dutiable value, not on freight and insurance.

If you import anything from China, you've been living with Section 301 tariffs since 2018. But the environment has changed dramatically, and what worked as a cost strategy a few years ago may not hold up now. This is not a political analysis. It is a practical explanation of what Section 301 tariffs are, how they work, what changed recently, and what options U.S. importers actually have.

What is Section 301?

Section 301 is a provision of the Trade Act of 1974 that gives the U.S. Trade Representative (USTR) authority to investigate and respond to foreign trade practices found to be unfair or discriminatory. That response can include tariffs on a specific country's goods, imposed without going through the standard WTO dispute process.

In 2018, USTR used Section 301 to impose tariffs on Chinese goods after concluding that China engaged in unfair technology transfer and intellectual property practices. Those tariffs were rolled out in four lists. Later administrations kept them and added to them, and in 2026 Section 301 became the main tool for broad new tariffs on many countries after the Supreme Court struck down the IEEPA tariffs in February.

What are the Section 301 China lists and rates?

The original China tariffs are organized into four lists. Lists 1, 2, and 3 generally carry 25%, List 4A carries 7.5%, and List 4B was never imposed. Together they cover hundreds of billions of dollars of Chinese goods across nearly every product category, from machinery and electronics to furniture and apparel.

List 3 was the big one. It started at 10% and rose to 25% in May 2019. List 4A took effect at 15% in September 2019 and was cut to 7.5% in February 2020 under the Phase One trade deal. List 4B was suspended, which is why many laptops and smartphones carry no list-based Section 301 duty. To see which list covers your product, you need its exact HTS code. See how to read an HTS code.

What changed in Section 301 from 2024 to 2026?

Three things changed. The 2024 four-year review raised rates sharply on strategic Chinese goods, phased in through 2026. The IEEPA tariffs that drove most 2025 increases were struck down in February 2026. And in July 2026, USTR imposed new forced-labor Section 301 tariffs on 60 economies, including China.

The 2024 four-year review

According to the presidential memorandum on the four-year review, the increases target strategic sectors, with several phased in over three years:

Medical products such as syringes, needles, and medical gloves also saw large increases. The rest of the China tariffs stayed at their existing levels.

2025 and the IEEPA reversal

Most of the new tariffs on Chinese goods in 2025 came under the International Emergency Economic Powers Act (IEEPA), not Section 301. The Supreme Court struck those down on February 20, 2026, and they are now being refunded. A temporary 10% Section 122 surcharge filled the gap until July 24, 2026.

The 2026 forced-labor tariffs

On July 24, 2026, forced-labor Section 301 tariffs replaced the Section 122 surcharge. According to Global Trade Alert's overview of the final action, the duties are 10% or 12.5% across 60 economies, and China, Brazil, Vietnam, and others pay the flat 12.5% rate. These tariffs stack on top of the original China lists. USTR's separate excess-capacity investigation into 16 economies could add another layer.

How are Section 301 tariffs calculated at the border?

Section 301 tariffs are calculated as a percentage of the goods' dutiable value, which is generally the transaction value excluding international freight and insurance. They are added on top of the regular duty rate. The importer of record pays them at entry, and each Section 301 action is reported with its own Chapter 99 number.

Here is an illustrative example for a Chinese-origin product on List 3 with a 3% regular duty rate:

That is a 40.5% duty on every shipment of that product. The tariff is assessed on the importer of record. Your Chinese supplier does not pay it. Any supplier who says the tariff is their problem is mistaken or folding the cost into its price.

Not every product carries every layer. Goods already subject to Section 232 duties, such as covered steel and aluminum articles, are exempt from the forced-labor tariff, and USMCA-qualifying goods from Mexico and Canada are exempt too. Section 301 actions are cumulative with one another, according to Davis Wright Tremaine's analysis.

Why does country of origin matter so much?

Country of origin decides which Section 301 actions apply, so it matters as much as classification. Origin is not simply where goods shipped from. It is decided by substantial transformation: if a Chinese product gets only minimal processing elsewhere, it can still be Chinese-origin for tariff purposes, and CBP scrutinizes these cases closely.

Transshipment, which means routing Chinese goods through a third country without meaningful transformation to avoid tariffs, is customs fraud. Companies that do it face civil and criminal penalties that make the tariff look small. If a supplier pitches a country-of-origin arrangement that sounds too convenient, treat it as a serious red flag. Genuine diversification, with real manufacturing in Vietnam, Mexico, India, or elsewhere, is legitimate. It requires real supply chain changes, not a different stamp on the box.

How can you reduce Section 301 tariff exposure? 7 strategies

Seven legitimate strategies reduce Section 301 exposure: HTS classification review, first sale valuation, existing exclusions, duty drawback, bonded warehouses and FTZs, USMCA-qualifying diversification, and total landed cost modeling. None is a magic fix, but combined they cut real cost without creating compliance risk.

1. HTS classification review

The most common and most underused strategy is making sure goods are classified correctly. Different codes in the same product family can fall on different lists or none at all. Overpaying because of misclassification is surprisingly common, and a licensed customs broker can confirm whether you're paying more than you owe.

2. First sale valuation

Duties are normally calculated on the price you pay your seller. If you buy through a trading company and there was an earlier sale from the factory to that intermediary, U.S. law may let you use the lower first-sale price as dutiable value, provided the sale was for export to the U.S. and is well documented. That lowers the base for every Section 301 layer.

3. Existing exclusions

According to Thompson Hine, the 178 remaining China Section 301 exclusions were extended into November 2026. Great Lakes Customs Law notes there is no opportunity to request new exclusions under this process. If your product matches an exclusion exactly, claim it now, and watch for USTR's decision before the November expiration.

4. Duty drawback

Section 301 duties are drawback-eligible, including the forced-labor tariffs. If you export goods that contain Chinese components, or re-export imported goods, you may recover 99% of eligible duties. See our duty drawback guide for the rules.

5. Bonded warehouses and FTZs

Goods in a bonded warehouse or foreign trade zone don't owe duty until they enter U.S. commerce, and goods re-exported from them may never owe it. However, goods subject to Section 301 must be admitted to FTZs in privileged foreign status, which locks in their duty treatment. These tools defer cost more than they reduce it.

6. Diversification, especially USMCA

Moving production outside China avoids the China lists, but most alternatives now face the forced-labor tariff. The biggest structural advantage belongs to USMCA-qualifying goods from Mexico and Canada, which are exempt. See nearshoring to Mexico for what that requires.

7. Total landed cost modeling

Section 301 is often the largest variable in the landed cost of Chinese goods. Beyond Logix's strategic sourcing team models landed cost across sourcing scenarios so you can compare real totals before committing to a supply chain shift.

What are importers getting wrong about Section 301?

The most common Section 301 mistakes are relying on old classification decisions, treating the tariff as a fixed cost, underestimating the paper trail CBP expects, and ignoring downstream effects on pricing and competitiveness. Each one quietly costs importers money or exposes them to audit risk.

Frequently asked questions

What is Section 301 and why does it exist?

Section 301 is a provision of the Trade Act of 1974 that lets the U.S. Trade Representative respond to foreign trade practices found to be unfair or discriminatory, including by imposing tariffs. The first modern Section 301 tariffs on China began in 2018 after an investigation into technology transfer and intellectual property practices.

What are the current Section 301 tariff rates on Chinese goods?

Goods on Lists 1, 2, and 3 generally pay 25%, and List 4A goods pay 7.5%. Strategic products carry higher rates after the 2024 review, including electric vehicles at 100% and solar cells and semiconductors at 50%. Since July 24, 2026, most Chinese goods also pay a separate 12.5% forced-labor Section 301 tariff.

Who pays Section 301 tariffs?

The U.S. importer of record pays Section 301 tariffs at customs entry, based on the dutiable value of the goods. The foreign supplier does not pay them. If a supplier offers to handle the tariff, clarify exactly what you are being charged and who is the importer of record.

Does Section 301 apply only to China?

Not anymore. The original Section 301 lists apply to Chinese goods, but in July 2026 USTR imposed forced-labor Section 301 tariffs of 10% or 12.5% on 60 economies, and a separate Section 301 action applies to Brazil. Each action has its own rates, exemptions, and Chapter 99 codes.

Can I get an exclusion from Section 301 tariffs?

Only for products already covered by an active exclusion. The 178 remaining China exclusions were extended into November 2026, but there is currently no open process for new exclusion requests under those extensions. Exclusions are product-specific, time-limited, and must match the exact product description.

How do I know which Section 301 rate applies to my product?

Start with the correct 10-digit HTS code and the country of origin. Then check the code against each Section 301 action, including the China lists, the four-year review increases, and the forced-labor tariff, plus any exclusions or exemptions. A licensed customs broker handles this as part of every entry.

Are Section 301 tariffs permanent?

They have no fixed end date. Section 301 tariffs stay in effect until USTR modifies or ends them, and actions are subject to periodic statutory reviews. The China tariffs have now lasted since 2018 across multiple administrations, so importers should plan around them continuing rather than expecting removal.

Can I avoid Section 301 tariffs by shipping from Vietnam or Mexico?

Only if the goods genuinely originate there through substantial transformation. Routing Chinese goods through another country without real manufacturing is transshipment and customs fraud. Genuine production in Vietnam avoids the China lists but still faces the forced-labor tariff, while USMCA-qualifying goods from Mexico are exempt from it.

Conclusion: plan for Section 301 to stay

Section 301 tariffs are no longer a China-only program. Chinese goods carry the original lists, higher strategic rates, and a 12.5% forced-labor layer, while 59 other economies face their own forced-labor rate. Correct classification, first sale valuation, exclusions, drawback, and smart sourcing remain the legitimate ways to reduce the cost.
