Section 301 Tariffs on Chinese Imports: What US Importers Need to Know in 2026
What Are Section 301 Tariffs?
Section 301 tariffs are additional duties imposed by the United States on goods imported from China. The Office of the United States Trade Representative (USTR) authorized these tariffs under Section 301 of the Trade Act of 1974 after an investigation determined that China’s trade practices related to technology transfer, intellectual property, and innovation were unreasonable and discriminatory.
The tariffs were implemented in four rounds (Lists 1 through 4) beginning in July 2018. They affect approximately $370 billion worth of Chinese goods entering the United States annually. The tariff rates range from 7.5% to 25% depending on the product list, and they apply on top of the standard Most Favored Nation (MFN) duty rates already in effect.
The USTR maintains the official list of affected products on its website at ustr.gov/issue-areas/enforcement/section-301-investigations. Every importer shipping from China to the USA should verify their specific Harmonized Tariff Schedule (HTS) codes against this list before booking freight.
Which Products Are Affected?
The four tariff lists cover a broad range of product categories. Here is the breakdown by list and rate:
List 1 (25% tariff, effective July 2018)
Covers $34 billion in Chinese goods. Primary categories include industrial machinery, electrical equipment, aircraft parts, medical devices, and nuclear reactor components. The full schedule is published in Federal Register Notice 83 FR 40823.
List 2 (25% tariff, effective August 2018)
Covers $16 billion in additional Chinese goods. Primary categories include semiconductors, chemicals, plastics, motorcycles, and railway equipment. Published in Federal Register Notice 83 FR 47974.
List 3 (25% tariff, effective May 2019)
The largest list at $200 billion in Chinese goods. Originally set at 10%, increased to 25% in May 2019. Covers thousands of product categories including furniture, leather goods, building materials, auto parts, agricultural products, textiles, and consumer electronics. Published in Federal Register Notice 83 FR 47974.
List 4A (7.5% tariff, effective February 2020)
Covers approximately $120 billion in Chinese goods. Includes consumer products such as smartphones, laptops, clothing, footwear, toys, and sporting goods. Originally set at 15%, reduced to 7.5% under the Phase One trade agreement. Published in Federal Register Notice 84 FR 57144.
How Section 301 Tariffs Are Calculated
Section 301 duties are calculated on the customs value of the imported goods (typically the transaction value under Incoterms FOB or CIF) and are assessed in addition to the regular MFN duty rate. The calculation works as follows:
For a shipment of industrial machinery (HTS 8479.89.9899) valued at $50,000 FOB Shanghai:
– MFN duty rate: 2.5% = $1,250
– Section 301 tariff (List 1, 25%): $12,500
– Total duty: $13,750 (27.5% effective rate)
– Merchandise Processing Fee (MPF): 0.3464% = $173.20
– Harbor Maintenance Fee (HMF, ocean only): 0.125% = $62.50
The total government charges on this shipment would be $13,985.70 before any state or local taxes.
US Customs and Border Protection (CBP) collects Section 301 duties at the time of entry. The importer of record is responsible for payment. CBP’s Automated Commercial Environment (ACE) system applies the additional duties automatically based on the HTS classification and country of origin. The official CBP guidance on Section 301 duties is published at cbp.gov/trade/programs-administration/entry-summary/section-301-trade-remedies.
Exclusions and Exemptions
The USTR has granted product exclusions for specific HTS subheadings where the tariffs cause disproportionate economic harm to US businesses. These exclusions have been granted, expired, and in some cases reinstated multiple times since 2018.
Key points about exclusions:
– Exclusion requests are filed through the USTR’s online portal at exclusions.ustr.gov
– Each exclusion specifies the exact HTS code, product description, and annual import volume
– Granted exclusions are retroactive to the date the applicable tariff took effect
– Most exclusions have expiration dates and must be renewed
– The Federal Register publishes all granted and denied exclusion decisions
As of 2026, the majority of previously granted exclusions have expired. The USTR periodically announces new exclusion processes, so importers should monitor the Federal Register and USTR announcements.
Impact on Freight Forwarding and Logistics
Section 301 tariffs have fundamentally changed the economics of China-to-USA freight forwarding. The additional 7.5% to 25% duty on top of existing MFN rates means that accurate HTS classification is no longer just a compliance exercise. It directly determines whether a product is commercially viable to import from China.
For freight forwarders and customs brokers, the operational impacts include:
HTS classification accuracy is critical. A single digit difference in the HTS code can mean the difference between 0% and 25% in additional duties. CBP has increased audits and penalties for misclassification. The Binding Ruling process through CBP (rulings.cbp.gov) provides definitive classification guidance.
Country of origin determination matters more. Products substantially transformed outside China may avoid Section 301 tariffs even if components originate in China. CBP applies the “substantial transformation” test on a case-by-case basis. This has led to significant supply chain shifts toward Vietnam, India, Mexico, and other manufacturing countries.
Customs bond sufficiency. The increased duty amounts mean that continuous customs bonds may need to be increased. A standard $50,000 continuous bond may not be sufficient for importers with high-value Chinese goods. CBP can demand additional bond security if duty deposits exceed the bond amount.
Forced labor enforcement. The Uyghur Forced Labor Prevention Act (UFLPA) adds an additional layer of compliance for Chinese imports. CBP’s Forced Labor Division reviews shipments flagged under UFLPA, which can result in detentions lasting weeks. The entity list is maintained at dhs.gov/uflpa-entity-list.
Strategies to Manage Section 301 Costs
1. Verify your HTS classifications. Request a binding ruling from CBP for your top-volume products. This provides legal certainty and protects against reclassification penalties.
2. Check for active exclusions. Monitor the USTR exclusion portal and Federal Register for your specific HTS codes. Even if a previous exclusion expired, new rounds are periodically announced.
3. Evaluate Foreign Trade Zones (FTZ). Importing goods into an FTZ allows you to elect the duty rate at the time of entry into US commerce rather than at the time of importation. This can be advantageous if you re-export some goods or if duty rates change. The FTZ Board maintains the list of approved zones at enforcement.trade.gov/ftzpage.
4. Consider duty drawback. If you export goods that were previously imported with Section 301 duties, you may be eligible for a 99% refund of the duties paid. CBP’s drawback program is detailed at cbp.gov/trade/programs-administration/entry-summary/drawback.
5. Diversify sourcing. For products where Section 301 tariffs make Chinese sourcing uncompetitive, evaluate manufacturing in countries with US free trade agreements (FTAs) or Generalized System of Preferences (GSP) eligibility. The USTR maintains the list of FTA partner countries at ustr.gov/trade-agreements/free-trade-agreements.
6. First Sale valuation. If your supply chain involves a middleman (buying agent or trading company), you may be able to declare the “first sale” price (manufacturer to middleman) as the customs value rather than the higher “last sale” price (middleman to importer). This reduces the value on which duties are calculated. CBP has specific requirements for first sale eligibility.
