Prepared Glues, Adhesives & Retail-Packaged Adhesive Products

The heading explicitly includes products put up for retail sale in packages not exceeding one kilogram net weight, regardless of the adhesive chemistry. This means a small tube of cyanoacrylate or a consumer epoxy kit qualifies here even if the same chemistry in bulk form might classify under a more specific heading. Importers should verify that the net weight per retail unit is accurately declared, as misclassification between retail and bulk can affect both duty rates and labeling requirements.

For adhesives potentially subject to Section 301 tariffs — particularly those sourced from or transshipped through China — CBP expects a manufacturer's affidavit or certificate of origin, production records demonstrating where substantial transformation occurred, and, for complex formulations, a bill of materials identifying the origin of key chemical inputs. Working with a licensed customs broker is advisable when supply chains involve multiple processing countries.
