7507.12.00.00 - Of nickel alloys

This HTS classification covers nickel alloy tubes and pipes. These items are designed for conveying fluids or gases and are distinguished by their composition, which includes nickel as a primary component along with other alloying elements that modify its properties. This category encompasses hollow cylindrical products used in various industrial applications where the specific metallurgical characteristics of nickel alloys, such as corrosion resistance or high-temperature strength, are required.

This category is distinct from HTS code 7507.11.00.00, which covers tubes and pipes made of nickel that is not alloyed. The key differentiator lies in the material composition: this classification specifically addresses articles where nickel is combined with other metals or non-metals to form alloys, whereas the sibling category is for pure nickel. The presence and type of alloying elements are the crucial factors for correct classification.

As this is a terminal node within the Harmonized Tariff Schedule, there are no further subcategories branching from this specific HTS code. Classification at this level is based on the material being nickel alloys, and the form factor being tubes or pipes. Therefore, any imported or exported goods meeting these criteria would be classified here, assuming they are not fittings, which fall under a separate HTS heading.
