Under the Lacey Act, importers must file a plant and plant product declaration stating the genus and species of the wood, the country of harvest, and the quantity. Failure to declare accurately can result in seizure or penalties, so verifying species information with the foreign supplier before shipment is essential.

The two subheadings (441410 for tropical wood and 441490 for non-tropical wood) carry separate tariff lines and may face different duty treatment. Additionally, Section 301 measures apply based on country of origin, so frames from China face additional tariffs regardless of wood species. Confirm the applicable rate at the 10-digit HTS level with a licensed customs broker.
