Wood products & panels

Panels are classified by construction, not by what they will be used for. The buyer thinks in terms of grades and finishes. The tariff thinks in terms of ply count, ply thickness, the species group of the outer layer and whether the surface is covered. Those are different vocabularies, and the gap between them is where wrong entries are made.

Getting the subheading right

Within plywood and laminated wood, the breakouts depend on whether any single ply exceeds six millimetres, whether the outer ply is coniferous, one of the tropical woods named in the chapter notes, or another non-coniferous species, and whether the face is surface covered. Fibreboard is split by density and by mechanical treatment. Particleboard, oriented strand board and laminated veneer lumber each sit somewhere different again, and builders’ joinery is a separate heading from the panel it was cut from.

This is the single most common defect we find when we take over a file from another broker: a plausible ten digit code that was right for one product and has been reused for four years across a catalogue that has since changed. We rebuild the classification against the construction sheet once, then hold it.

Formaldehyde: TSCA Title VI

Hardwood plywood, medium density fibreboard and particleboard are regulated for formaldehyde emissions, as are finished goods made with them. The federal standard came out of the California Air Resources Board Phase 2 programme, but it is the federal rule that is enforced at the border.

Compliance is a chain, and every link is checkable. The panel is certified by a third party certifier that EPA recognises. The panel is labelled. The importer files a certification with the entry and keeps the supporting records. When EPA or CBP asks a question, they ask for the whole chain, so a certificate on its own is not an answer.

The failures are consistent. A certificate that names a mill which is not the mill that pressed your panels. A certifier whose recognition has lapsed. A laminated product treated as exempt when the exemption no longer covers it. We check the certifier against EPA’s published list and the mill against your purchase order before the entry goes in, because after the container is on a hold you are buying time as well as compliance.

Antidumping follows the supply chain

The hardwood plywood cases have moved the way the trade has moved. The original order covered China. An anti-circumvention inquiry then reached panels finished elsewhere in Asia on Chinese cores, and later petitions have been aimed at those countries directly. Changing the country on the bill of lading has not been a strategy for some years.

Scope is decided by the written description in the order, not by the HTS number, which is included only for convenience. Two panels that look identical on a pallet can be in and out of scope depending on core composition, face species and thickness. Where the answer is genuinely unclear, the route is a scope ruling request to Commerce, not an optimistic entry. Deposits are cash, liquidation can be years away, and an entry filed without a required case number is a false statement rather than a disagreement.

Tariff exposure

The Section 232 action on timber and lumber reaches panel products and an expanding list of downstream wood articles, with rates that stepped up at the start of 2026 for the derivative categories. Section 301 applies where the origin is China. Tariffs imposed under the emergency economic powers statute apply by country and sit on top. Origin for a panel is where it was manufactured, which means where the veneers were laid up and pressed, not where it was packed or transshipped.

Where a rate is under challenge, we keep entries positioned so a refund can actually be claimed: a post summary correction while the entry is unliquidated, a protest within one hundred and eighty days after it liquidates. That only works if somebody is watching the liquidation dates, which is part of the job here and not an extra.

What we need from you

• A construction sheet per item: number of plies, thickness of each, species by layer, core type, adhesive, surface treatment.
• The third party certificate and the name of the mill that pressed the panel.
• Lacey Act species and harvest country for each layer. Our lumber and flooring page goes through that declaration in detail.
• Any CBP ruling you have relied on, and any Commerce scope ruling that covers your product.
• Invoice and packing list keyed to the same item numbers as the construction sheet, so the entry can be built from data rather than from a phone call.
