The Lacey Act requires importers of products containing plant materials — including teak furniture — to file a Plant and Plant Product Declaration (PPQ 505) at entry, identifying the genus and species (Tectona grandis for teak), the country where the wood was harvested, the quantity, and the unit of measure. Failure to file an accurate declaration can result in civil or criminal penalties. Importers should obtain chain-of-custody documentation from suppliers to support the declaration.

The US tariff schedule isolates teak (Tectona spp.) furniture at 9403608089 because teak is a commercially and regulatorily distinct species — it commands premium pricing, has specific sustainability and origin-documentation concerns, and has historically been subject to trade-policy scrutiny related to tropical hardwood sourcing. The dedicated line allows CBP and other agencies to track teak imports separately from general wooden furniture.
