Last updated: August 2026 dataParticle board — manufactured by bonding wood chips, shavings, or sawdust with synthetic resins under heat and pressure — is a foundational panel product for furniture, cabinetry, and interior construction. Formaldehyde emissions from the resin binders are regulated under the California Air Resources Board (CARB) ATCM and the federal Formaldehyde Standards for Composite Wood Products Act, administered by EPA, making emissions certification a mandatory compliance step for US importers. Certain particle board imports, particularly from China, have been subject to antidumping and countervailing duty proceedings.

Under the EPA Formaldehyde Standards for Composite Wood Products Act (TSCA Title VI), importers must ensure particle board meets Phase 2 emission limits and is produced by a CARB-approved or EPA-recognized third-party certifier. Importers must also maintain records of certification and be prepared to provide them to CBP or EPA upon request. Non-compliant product can be refused entry or recalled.
The 'similar board' language captures oriented strand board (OSB) and other engineered panels made from wood particles or strands bonded with adhesives, provided they are not more specifically described elsewhere. Medium-density fiberboard (MDF), which uses finer wood fibers, is typically classified under a separate heading. Importers should confirm the panel's raw material form — particles vs. fibers — to determine the correct classification.
