Import Tips

Obtain supplier certification confirming MDF density (0.45-0.80 g/cm³), thickness ≤5mm, and edge profiling meets 'tongued, grooved or rabbetted continuously' specs

Include technical datasheets proving dedication for wall/ceiling construction to avoid reclassification as general panels under 4411.12.20

Test for formaldehyde emissions (CARB Phase 2 or TSCA Title VI compliance) as required for US building product imports
