Wrought copper fittings — couplings, elbows, tees, reducers, and sleeves — are joining components for plumbing, HVAC, and industrial piping systems, and are among the copper products most frequently subject to antidumping and countervailing duty orders from multiple origins. ASME B16.22 (wrought copper) and ASME B16.18 (cast copper alloy) are the governing dimensional standards in the US market, and importers must confirm which standard applies to their product, as the distinction affects both classification and buyer acceptance. The fitting type (solder-joint, press-fit, or flare) and pressure rating are specification variables that should be documented on commercial invoices. Given the history of trade-remedy actions in this product category, importers are strongly advised to conduct origin and scope analysis before committing to a supply source.

Copper fittings have been among the most actively litigated product categories in US antidumping and countervailing duty proceedings, with orders covering imports from multiple countries at various times. Even small changes in supplier country can dramatically affect landed cost. Importers should verify the current status of any applicable orders with the International Trade Administration and obtain a scope ruling if the product's coverage is ambiguous.
Wrought fittings are formed from copper or copper alloy that has been mechanically worked (drawn, extruded, or forged) and typically conform to ASME B16.22; cast fittings are produced by pouring molten metal into a mold and conform to ASME B16.18. The manufacturing method affects both the applicable ASTM/ASME standard and, potentially, the tariff classification. Mill or manufacturer certifications identifying the production method should accompany the import entry.
