Importers should provide a commercial invoice that clearly states the material is distributed free of charge or at nominal cost for promotional purposes, along with a description of the intended distribution method (e.g., trade show giveaway, direct mail to customers). A letter from the foreign supplier confirming the advertising purpose can also support the classification claim if CBP questions the entry.

Trade-remedy measures (antidumping, countervailing duty, Section 301) are product- and country-specific. Printed advertising materials are not typically subject to active trade-remedy orders, but importers sourcing from countries with broad Section 301 coverage should verify the specific HTS subheading at the 10-digit level, as applicability depends on the precise classification rather than the general heading.
