THE DETAIL THAT MATTERS

Can I copy a supplier's tariff code without checking it?

Classify the actual product by material, construction and use. A supplier's code is a starting point, not a binding destination-country decision.

ILLUSTRATIVE EXAMPLE

Similar appearance, different classification facts

A chair’s materials, construction and intended use can affect its classification. Give the broker a product specification and photos; do not copy a code from an unrelated chair listing.

Product codes do different jobs

Code	Purpose
HS	International goods classification at six digits
National tariff code	Destination-specific tariff detail
ECCN	U.S. export-control classification
SKU	A business’s own inventory identifier
