Mosaic floor panels consist of small wood fingers, slats, or blocks — typically under 6 cm in width — assembled into a larger tile or sheet, often with a paper, mesh, or foil backing. They are distinguished from standard parquet panels and multilayer planks by the small element size and the geometric or decorative pattern formed by the assembly. CBP may request product samples or technical specifications to confirm the mosaic classification.

Both subheadings carry the same general column 1 rate of duty, but the distinction matters for accurate statistical reporting and for any trade remedy scope analysis. Solid mosaic panels (4418741000) are composed entirely of wood without a composite backing, while 4418749000 captures panels with backing materials or mixed construction. Correct subheading selection also ensures proper Lacey Act species declarations.
