Plastics and articles thereof — ruling case studies
Chapter 39 covers plastics and articles of plastics — and it is one of the trickiest chapters to classify in, because it is full of headings that look interchangeable but carry hidden conditions. Heading 3918 (floor coverings of plastics) only applies to goods 'in rolls or in the form of tiles'; heading 3921 covers other plates and sheets; and heading 3926 is the residual 'other articles of plastics' where goods land when no more specific heading fits. The case studies below show how a plausible-sounding plastics heading can still be the wrong one, and why construction and form matter more than the product's marketing name.

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.
