Product classification
HS code for Stainless steel pipe bends: 7307.22
Steel, stainless, tube or pipe fittings, threaded elbows, bends and sleeves.
Classification of stainless steel pipe bends under HS 7307.22
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.

Codes often confused with 7307.22
Common mistake. 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.
Top exporters and importers of HS 730722 (the code used for stainless steel pipe bends), 2025
In 2025, the largest exporter of HS 730722 (the code used for stainless steel pipe bends) in UN Comtrade data was the United States, with 33% of world exports; the largest importer in UN Comtrade data was the United States, with 10% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about stainless steel pipe bends
What is the HS code for Stainless steel pipe bends?
The HS code for Stainless steel pipe bends is 730722 (Steel, stainless; tube or pipe fittings, threaded elbows, bends and sleeves). The HS code for threaded stainless steel pipe bends is 7307.22. If the bends are for butt-welding, the code is 7307.23.
How do I classify Stainless steel pipe bends for customs?
Stainless steel pipe bends is classified under HS code 730722 — Steel, stainless; tube or pipe fittings, threaded elbows, bends and sleeves. This is a 6-digit subheading level code.
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.
Which countries are the top exporters of stainless steel pipe bends (HS 730722)?
