About HS Code 740931

This HS code covers bronze strip (copper-tin base alloys) with a thickness greater than 0.15mm, supplied in coiled form. Bronze strips are highly valued in international trade for their superior strength, wear resistance, fatigue resistance, and good corrosion properties, making them ideal for demanding mechanical and electrical applications. They are extensively used in the production of springs, connectors, bearings, bushings, and electrical contacts, particularly in automotive, electronics, and marine industries. Industrialized nations with advanced manufacturing sectors, such as Germany, Japan, and the United States, are significant importers, requiring these specialized materials for high-performance components. Exporters often include countries with strong metallurgical industries and advanced rolling capabilities, like China, South Korea, and Germany. Key trade considerations include the specific bronze alloy (e.g., phosphor bronze, tin bronze), temper, dimensions, and surface quality, all critical for precision manufacturing.

Products Under This Code

Phosphor bronze strip, Tin bronze strip, C51000 phosphor bronze coil, C52100 phosphor bronze coil, Bearing bronze strip, Spring bronze strip, Electrical contact bronze strip

Real World Examples

Wieland Phosphor Bronze Strip, KME Bronze Coil, Aurubis Bronze Strip, Luvata Phosphor Bronze Coil

Common Misclassification

This code can be confused with 740939 if the bronze is in flat sheets rather than coils, or with 740921 if the material is brass instead of bronze. The key is the specific copper-tin alloy and the coiled form.
