Product classification
HS code for Stainless steel threaded fittings: 7307.22
Steel, stainless, tube or pipe fittings, threaded elbows, bends and sleeves.
Classification of stainless steel threaded fittings under HS 7307.22
Stainless steel threaded fittings are classified under HS code 7307.22. This classification falls within Chapter 73, which covers articles of iron or steel. Heading 7307 is dedicated to tube or pipe fittings, including couplings, elbows, and sleeves. The 7307.2x sub-series is specifically designated for fittings made of stainless steel. Subheading 7307.22 is restricted to threaded elbows, bends, and sleeves. The classification is determined by three main factors: the material (stainless steel), the function (connecting pipes or tubes), and the method of connection (threading). Threaded fittings feature internal or external screw threads that allow for a mechanical connection without the immediate necessity of welding, although they are often used in conjunction with sealants in high-pressure fluid systems. The distinction between threaded and butt-welding or flange-type fittings is a fundamental requirement for correct customs declaration.

Codes often confused with 7307.22
Common mistake. A frequent mistake is using HS code 7307.21, which is specifically for flanges, or 7307.23, which is for butt-welding fittings. Butt-welding fittings lack threads and are joined by melting the metal. Furthermore, other types of stainless fittings that are not elbows, bends, or sleeves (such as tees, crosses, or plugs) should be classified under 7307.29. Misidentifying the connection type is the leading cause of duty errors in this category.

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).
