Yes, antidumping and/or countervailing duty orders have been applied to refined copper tube and pipe from certain countries. Importers must verify current orders and scope rulings at the specific tariff line and country of origin, as the scope of these orders can be narrowly defined and subject to change.

Tubes and pipes are classified under 7411, while the fittings used to join them — couplings, elbows, sleeves, and similar articles — are separately classified under heading 7412. Importing both together does not change their individual classifications; each component is assessed independently.
