HS Code for Bronze fittings

Bronze fittings are classified under HS code 7412.20. This heading covers tube or pipe fittings made of copper or copper alloys. The classification is based on the function of the product as a connector or component in a piping system. Subheading 7412.20 specifically applies to fittings made of copper alloys, which includes bronze (copper-tin alloys). These products are designed to join pipes or tubes, change the direction of flow, or adapt pipe sizes. The manufacturing process often involves casting or machining from bars or tubes. It is important to distinguish these from the pipes themselves (heading 7411) and from valves or similar appliances (heading 8481), which have a mechanical function beyond simple connection. Bronze is preferred for fittings in marine and plumbing environments due to its superior resistance to dezincification and salt-water corrosion. Classification requires that the fitting be primarily composed of a copper alloy where tin is a significant alloying element.

Products Included

• Bronze pipe elbows
• Bronze tube couplings
• Bronze T-junctions
• Bronze pipe sleeves
• Bronze unions and caps

Common Misclassification

Bronze fittings are frequently misclassified under 7412.10, which is reserved for fittings made of refined copper. They are also often confused with 8481.80 if the fitting includes a valve mechanism, as valves are classified by function rather than material. Additionally, cast iron fittings (7307) are sometimes confused with bronze if the surface finish is similar, though the base metal determines the chapter.

FAQ

What is the HS code for bronze fittings?

The HS code for bronze fittings is 7412.20, covering tube or pipe fittings of copper alloys.

Are bronze valves classified under the same HS code as bronze fittings?

No, bronze valves are generally classified under heading 8481 because they have a mechanical function to regulate flow, whereas 7412.20 is for static connection fittings.
