7412.20.00.35 - Other

This classification, HTS 7412.20.00.35, encompasses fittings for copper or copper alloy tubes and pipes that are specifically threaded and made from copper-zinc base alloys, commonly known as brass. These fittings are distinct from nipples (HTS 7412.20.00.25), which are typically short, straight lengths of pipe with external threads on both ends used for connecting two other fittings or pipes. The "Other" designation within this subcategory indicates fittings that, while threaded and made of brass, do not fall under the specific description of a nipple. Examples may include threaded elbows, tees, couplings, unions, or adapters designed for connecting threaded copper alloy piping systems where a specific nipple form is not applicable.

The defining characteristic for inclusion in this category is the combination of threaded ends and construction from copper-zinc alloys. Unlike fittings made from pure copper, these brass fittings offer enhanced strength and corrosion resistance suitable for a wider range of applications and pressures. The threaded nature is crucial, distinguishing them from compression fittings, sweat fittings, or flared fittings which rely on different connection mechanisms and are classified elsewhere.

As this is a leaf node in the HTS structure, there are no further subdivisions. Therefore, the focus for classification under HTS 7412.20.00.35 rests on accurately identifying the material as a copper-zinc alloy and confirming the presence of threaded connections, ensuring it is not specifically a nipple fitting.
