Section 301 Tariffs Explained for Ecommerce Sellers

How Section 301 tariff exposure can affect imported product costs and what sellers should model before pricing.

Quick Answer

Section 301 tariffs are additional duties on Chinese goods, 7.5-25%+ on top of standard rates. Most consumer goods from China are affected. A product facing 25% Section 301 on 8% standard rate pays 33% total duty.

Why It Matters

Section 301 is often the largest single cost after the product. Ignoring it is the fastest way to destroy margin.

Formula / Framework

Total Duty Rate = Standard Rate + Section 301 Rate. Total Import Cost = Customs Value x (1 + Total Rate) + Fees.

Example Scenario

$5,000 Chinese home goods. Standard 3.4%, Section 301 at 7.5%.

Standard Duty (3.4%)$170.00
