Compliance varies significantly by destination market. For the US market, ensure exporters comply with CARB Phase 2 or TSCA Title VI for formaldehyde emissions in composite wood, and TB117-2013 for flame retardancy. For the EU market, products must meet REACH chemical regulations and EN 12520 for strength and safety. Always request FSC (Forest Stewardship Council) certification to ensure the timber is legally and sustainably sourced, which is a critical requirement for customs clearance in many developed nations.
