Heading 7412

Copper tube or pipe fittings (for example couplings, elbows, sleeves)

8 declarable lines

Heading 7412 covers copper tube or pipe fittings such as couplings, elbows, sleeves and nipples. It is split first by material: refined copper under 7412.10 and copper alloys under 7412.20. The alloy lines then split by brake hose use for certain vehicles, brass versus other copper alloys, threaded versus other, and nipples versus other.

How to choose the right subheading

Decide whether the item is a fitting for joining tube or pipe, not the tube or pipe itself.
Check the metal: refined copper goes to 7412.10, copper alloys to 7412.20.
For copper alloys, identify whether the alloy is copper-zinc base (brass) or another copper alloy.
Determine whether the fitting is threaded and whether it is a nipple, since those split the alloy lines.
Check whether the fitting is for brake hoses on the listed vehicle types, which has its own alloy line.
