CDA 932 Bearing Bronze Ingot
CDA 932 bearing bronze is a copper-tin alloy containing about 83% copper, 7% tin, and 7% zinc, cast into ingots for further processing. It falls under HTS 7403.29.01 as an unwrought copper-tin base alloy (bronze) that does not meet master alloy specifications. These ingots are melted down to produce bushings and bearings.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If zinc-predominant brass alloy
Shifts to copper-zinc base alloys (brasses) per subheading note (a) when zinc exceeds other elements.
If processed into billets or bars
Unwrought ingots become semi-manufactured products under heading 7407 once shaped or worked.
If qualifying as master alloy
Master alloys of copper for metalworking use fall under heading 7405, distinct from standard unwrought alloys.

Import Tips & Compliance
• Provide detailed alloy composition certificates confirming tin predominance and zinc under 10% to verify bronze classification
• Ensure ingots are free of impurities exceeding subheading tolerances; test reports prevent reclassification as waste
• Declare exact weight and dimensions; bulk shipments often trigger valuation disputes
