Import Tips & Compliance

Provide lab analysis or supplier certification for stain composition to prove it qualifies as a 'preservative' under tariff terms

Inspect for over-treatment; excessive paint-like coatings may shift classification to painted wood articles

Declare exact species (e.g

white oak) for accurate nonconiferous status and quota considerations
