Anti-dumping / countervailing risk — read this before you buy
Separate from the tariffs above, these trade-remedy cases are linked to this code. They are not included in the 41.2% above, because they depend on the exact product and the company that made it.
What we found: the case(s) below name products under this code.
Why it may affect your shipment: if your product falls inside the case's written scope, extra duties — sometimes over 100% — are collected at entry.
What is still missing: only the written scope in the official order decides; a shared code is not proof.
Where to check: read the scope in the official order (linked from the case number via our sources page) or ask your customs broker before ordering.
