Cupro-Nickel & Nickel-Silver Tubes and Pipes

Cupro-nickel alloys are copper-nickel binary or near-binary alloys (commonly 90/10 or 70/30 Cu/Ni grades) with no significant zinc content. Nickel-silver adds zinc to the copper-nickel base, producing a silvery appearance used in decorative and instrument applications. Both fall under 7411220000, but the alloy designation on the mill certificate must clearly identify the base system to support the classification.

Mexico's position reflects established manufacturing capacity for specialty copper alloy tubular products serving North American industrial and HVAC markets. As a USMCA partner, qualifying goods of Mexican origin may be eligible for preferential duty treatment, provided the product meets the applicable rules of origin — including tariff shift and, where required, regional value content thresholds. Importers should confirm USMCA eligibility with a licensed customs broker.
