Navigating Section 301 Tariffs on Chinese Goods

What Are Section 301 Tariffs?

Section 301 tariffs are additional duties imposed by the United States Trade Representative (USTR) on goods imported from China, authorized under Section 301 of the Trade Act of 1974. Originally imposed in 2018, these tariffs were a response to China's practices regarding intellectual property theft, forced technology transfer, and unfair trade practices. The tariffs affect approximately $370 billion worth of Chinese imports and add 7.5% to 25% additional duty on top of the standard Column 1 General rate. For many products, Section 301 tariffs have fundamentally changed the economics of sourcing from China.

The Four Tariff Lists

• List 1 (effective July 2018): $34 billion in goods, 25% additional tariff. Covers industrial machinery, electronics, and aerospace components.
• List 2 (effective August 2018): $16 billion in goods, 25% additional tariff. Covers semiconductors, chemicals, plastics, and motor vehicles.
• List 3 (effective September 2018, escalated May 2019): $200 billion in goods, 25% additional tariff. Broadest list, covering thousands of consumer and industrial products.
• List 4A (effective September 2019): $120 billion in goods, 7.5% additional tariff. Covers consumer goods, apparel, and electronics not on earlier lists.

How to Check if Your Product Is Affected

Section 301 tariffs apply based on the 8-digit HTS code and the country of origin. To determine if your product is affected: 1) classify the product under the correct HTS code, 2) check whether that HTS code appears on any of the four Section 301 lists, and 3) confirm that the country of origin is China. The USTR maintains the complete lists on its website, and USITC provides a searchable HTS database with Section 301 annotations. TariffPro automatically flags Section 301 tariffs when you classify a product, showing the applicable list and additional duty rate.

Exclusion Process

The USTR has periodically offered exclusion processes where importers can request that specific products be excluded from Section 301 tariffs. Exclusion requests must demonstrate that the product is not available from non-Chinese sources, that the tariff causes severe economic harm to the requestor, and that the product is not strategically important to China's industrial policy goals. Exclusions are time-limited (typically 12 months) and may or may not be renewed. As of 2026, most previously granted exclusions have expired, and new rounds are limited.

Strategies to Manage Section 301 Exposure

• Supply chain diversification: Source from non-China origins (Vietnam, India, Mexico, Thailand) where economically viable.
• Tariff engineering: Evaluate whether product modifications change the HTS classification to a code not on the Section 301 lists.
• First sale valuation: Use the first arm's-length sale price as the customs value to reduce the base on which the additional tariff is calculated.
• Foreign Trade Zones (FTZs): Admit goods into an FTZ under privileged foreign status to lock in the tariff rate; assess duties only when goods enter US commerce.
• Duty drawback: If you re-export goods or use them in products that are exported, you can recover up to 99% of the Section 301 duties paid.
• Bonded warehouse: Defer duty payment by storing goods in a bonded warehouse until you are ready to sell them domestically.

Using TariffPro to Navigate Section 301

TariffPro flags Section 301 tariffs automatically during classification. When you enter a product description, the results show the standard duty rate and any applicable additional tariffs, including the specific Section 301 list. You can also use TariffPro to model alternative classifications — enter different product descriptions or variations to see whether a legitimate product modification could result in an HTS code not covered by Section 301. This scenario analysis is invaluable for supply chain planning and tariff engineering.
