Official Chapter Guide

Copper metals and various alloys including brasses, bronzes, and nickel silvers, excluding certain chemical compounds.

Tariff Landscape

Chapter 74 goods are typically susceptible to duties, particularly copper products being affected by global trade measures.
Certain products may be subject to Section 301 tariffs if sourced from China.
Watch for anti-dumping and countervailing duty measures, especially concerning Chinese copper alloy products.

Common errors arise when distinguishing between refined copper, copper alloys, and master alloys.
To correctly classify copper alloys, ensure that the other elemental contents meet or exceed specified limits.
Brasses, bronzes, and nickel silvers have distinct component ratios that must be strictly adhered to.

Refined copper must contain at least 99.85% copper, or meet specific element limits if between 97.5% and 99.85%.
Copper alloys are defined by the prevalence of copper by weight but include other elements above specified limits.
Master alloys include more than 10% copper and are defined by their purpose rather than malleability.
Copper phosphide, when containing more than 15% phosphorus, is excluded and falls under heading 2853.
Defines specific alloy categories: brasses, bronzes, nickel silvers, and copper-nickel alloys with varying elemental compositions.
