Aluminum tube or pipe fittings (for example, couplings, elbows, sleeves)
1 declarable lines
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.
Products in this heading
- Aluminum pipe couplings
- Aluminum elbows for tube and pipe
- Aluminum sleeves and nipples
- Aluminum tees and crosses for pipe
- Aluminum reducers and adapters
- Aluminum flanges for welded or bolted pipe joints
- Aluminum threaded unions for tube lines
How to choose the right subheading
- Material: the article must be aluminum; the same shape in plastic or steel goes to a different heading.
- Function: the article must join, connect or terminate tube or pipe, not control flow.
- Article type: fittings are separate pieces, while pipe and tube in lengths go to 7608.
- Level of assembly: loose fittings stay in 7609, while assembled structural frames go to 7610.
- There is only one line, 7609.00.00.00, so no further split is required once the article is confirmed as an aluminum pipe fitting.
Often confused with
- Heading 7608Aluminum tube or pipe in straight lengths
The pipe or tube itself is classified in 7608; 7609 covers only the fittings that join it.
- Heading 8481Valves and valve bodies of aluminum
Valves control flow and are classified as valves, not as pipe fittings.
- Heading 3917Plastic pipe fittings
Material decides the heading; plastic fittings do not belong in chapter 76.
- Heading 7610Aluminum railings and other structures made with fittings
Fabricated structural assemblies are classified as structures, not as individual fittings.
- Heading 7616Aluminum bolts, nuts and threaded fasteners
General fasteners are not pipe fittings and fall to the residual aluminum heading.
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.
