Section 301 (China) tariffs

Section 301 tariffs — the extra ad-valorem duties on many China-origin goods under Chapter 99 (the 9903.88.xx headings) — often matter more to landed cost than the base HTS rate. These case studies are CBP rulings where a Section 301 measure is part of the picture: how the product was classified, and why the China-origin duty exposure turns on getting the HTS right. Educational reading — always verify the current Chapter 99 status and any exclusions with a licensed customs broker before entry.

This is general educational information compiled from public CBP CROSS rulings to help importers understand classification reasoning, duty differences and compliance risks. It is not a formal HTS classification, customs-broker service, entry instruction, duty determination, or legal advice for any specific shipment. Final classification depends on a product's actual material, construction, use, accessories, invoice description, country of origin, and current legal status. Importers should confirm with a licensed customs broker or trade counsel, or request a binding ruling from CBP, before entry.
