Not customs or legal advice

MetalAttest provides data for the importer's and customs broker's review. We do not classify goods and we do not give customs or legal advice. Your licensed customs broker decides classification and files the entry. The scope reference reproduces CBP's published lists for HTS numbers you look up; the calculator performs arithmetic on the weights you enter. Neither determines the classification, origin, or duty treatment of any product.
