Product classification
HS code for Stainless steel pipe fittings: 7307.29
Steel, stainless, tube or pipe fittings, n.e.c. in item no. 7307.2.
Classification of stainless steel pipe fittings under HS 7307.29
Stainless steel pipe fittings are classified under HS code 7307.29, which serves as a residual category for fittings not specifically named in other subheadings of 7307.2. Heading 7307 covers tube or pipe fittings such as couplings, elbows, and sleeves. The classification logic requires first identifying the material as stainless steel (Chapter 72, Note 1e). Once the material is confirmed, the specific type of fitting is evaluated. Subheading 7307.21 covers flanges, 7307.22 covers threaded elbows, bends, and sleeves, and 7307.23 covers butt-welding fittings. Therefore, 7307.29 is used for other types of fittings, such as compression fittings, certain types of valves bodies (if classified as fittings), or specialized connectors that do not meet the definitions of the preceding subheadings. This classification is vital for ensuring that the diverse range of components used to join or close pipe systems are correctly taxed and regulated based on their specific geometry and connection method.

Codes often confused with 7307.29
Common mistake. The most frequent misclassification occurs with 7307.22 (threaded elbows and sleeves) and 7307.23 (butt-welding fittings). Importers often default to 7307.29 without checking if the fitting is threaded or designed for butt-welding. Additionally, if a fitting is made of iron or non-stainless steel, it must be moved to 7307.91 through 7307.99. It is also important to distinguish between a fitting and a valve; valves are classified under heading 8481.
Top exporters and importers of HS 730729 (the code used for stainless steel pipe fittings), 2025
In 2025, the largest exporter of HS 730729 (the code used for stainless steel pipe fittings) in UN Comtrade data was Germany, with 15% of world exports; the largest importer in UN Comtrade data was China, with 11% of world imports.

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).
