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.
