HS Code for Stainless steel pipe bends

Stainless steel pipe bends are classified under HS code 7307.22 because they fall within Chapter 73, which covers articles of iron or steel, and specifically under heading 7307 for tube or pipe fittings. The classification is determined by the material composition and the specific function of the component. As these items are manufactured from stainless steel, they are directed toward the subheadings for stainless steel fittings (7307.21 through 7307.29). Subheading 7307.22 is explicitly reserved for threaded elbows, bends, and sleeves. The classification process follows the General Rules of Interpretation (GRI), specifically GRI 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Since these bends are threaded to allow for mechanical connection to pipes without the immediate necessity of welding, they meet the precise criteria for this code. The stainless steel designation requires a minimum chromium content of 10.5% and a maximum carbon content of 1.2% by weight, ensuring the product meets the metallurgical definitions of Chapter 72, which informs the material basis for Chapter 73.

Common Misclassification

A frequent error in classification involves confusing 7307.22 with 7307.23. While both cover stainless steel fittings, 7307.23 is strictly for butt-welding fittings. If the bend is designed to be welded rather than threaded, it must be moved to 7307.23. Additionally, 7307.21 is often mistakenly used; however, that code is reserved specifically for flanges. Another common misclassification is 7307.29, which is a residual category for \"other\" stainless steel fittings that are neither threaded nor butt-welding, such as compression fittings or socket-weld fittings.

FAQ

What is the HS code for stainless steel pipe bends?

The HS code for threaded stainless steel pipe bends is 7307.22. If the bends are for butt-welding, the code is 7307.23.

Does the grade of stainless steel change the HS code?

Generally, no. Whether the bend is made of Grade 304 or Grade 316 stainless steel, it remains under 7307.22 as long as it is a threaded fitting.
