About heading 7609
Aluminum tube or pipe fittings (for example, couplings, elbows, sleeves)
Heading 7609 covers aluminum tube or pipe fittings, meaning the connectors that join pieces of aluminum pipe or tube, such as couplings, elbows and sleeves. It has a single declarable line, 7609.00.00.00, so there are no subheadings to pick among. The heading covers fittings only, not the pipe or tube itself, and not valves or structural assemblies.

Frequently asked questions
What is the HTS code for aluminum tube or pipe fittings?
Aluminum tube or pipe fittings, including couplings, elbows and sleeves, are classified under 7609.00.00.00. The general (MFN) duty rate for that line is 5.7%.
What is the duty on aluminum pipe couplings and elbows?
They enter under 7609.00.00.00 and the general (MFN) rate is 5.7%. The rate is the same for all fittings in the heading because there is only one declarable line.
How do I classify an aluminum elbow used to join two pipes?
Classify it as 7609.00.00.00 at a general (MFN) rate of 5.7%, because it is an aluminum fitting that joins pipe. If the item is instead a valve or a finished structural assembly, it does not belong in heading 7609.
