Product classification
HS code for Steel pipe fittings: 7307.99
Iron or steel, tube or pipe fittings, n.e.c. in item no. 7307.9, other than stainless steel.
Classification of steel pipe fittings under HS 7307.99
HS code 730799 is utilized for tube or pipe fittings made of iron or steel, specifically those that are not made of stainless steel and are not cast iron. Heading 7307 is the primary category for all fittings used to join or close pipes, such as couplings, elbows, and sleeves. The classification process first distinguishes between cast fittings (730711/730719) and non-cast fittings. Then, it separates stainless steel (730721-730729) from other types of steel. Within the "other" steel category, specific subheadings exist for flanges (730791), threaded elbows/sleeves (730792), and butt-welding fittings (730793). HS code 730799 acts as the "other" category for fittings that do not fall into those specific geometric or functional sub-categories, ensuring all non-stainless steel pipe components are accounted for. This includes a variety of specialized connectors used in plumbing, industrial fluid transport, and structural piping systems.

Codes often confused with 7307.99
Common mistake. Steel pipe fittings are often misclassified under 730729 if the user assumes all high-quality steel is stainless; however, 730729 is strictly for stainless steel. Another common error is 730711 or 730719, which are reserved for cast iron fittings. If the fitting has a valve mechanism to control flow, it must be classified under heading 8481 (taps, cocks, and valves) rather than 7307. Additionally, threaded elbows and sleeves should be placed in 730792 rather than the 730799 basket 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).
