Last updated: July 2026 dataCellular wood panels — lightweight sandwich-construction panels with a hollow or honeycomb wood core bonded between face veneers or wood-based sheet material — are widely used in furniture, interior fit-out, and door manufacturing as a weight-reducing alternative to solid or particleboard substrates. Canada leads US imports under this heading, with Germany, China, Italy, and Brazil also among the top suppliers, reflecting both proximity and Europe's established panel-manufacturing industry. Chinese-origin panels may carry Section 301 tariff exposure, and the single US tariff line 4418920000 covers the full range of cellular panel constructions.

The defining characteristic of a cellular wood panel is its hollow or honeycomb internal structure, which differentiates it from solid-core panels like MDF, particleboard, or plywood. CBP focuses on the core construction: a panel with a grid, honeycomb, or otherwise hollow wood-based core bonded between face layers classifies under 4418920000, while solid-core panels fall under Chapter 44 headings for plywood or fiberboard.
Yes. Composite wood products, including panels with wood-based face layers or cores bonded with adhesives, are subject to EPA TSCA Title VI formaldehyde emission standards, administered through the California Air Resources Board (CARB) ATCM framework as incorporated into federal law. Importers must ensure products are certified by an EPA-recognized third-party certifier and that documentation accompanies the shipment.
