HS Code 7307.93 – Iron or steel; tube or pipe fittings, butt welding fittings, other than stainless steel

HS code 7307.93 is the 6-digit subheading for iron or steel, tube or pipe fittings, butt welding fittings, other than stainless steel. It is used for butt weld elbows, butt weld reducers, butt weld tees, butt weld caps and butt weld stub ends.

What HS 7307.93 covers

This category covers non-stainless iron or steel butt welding fittings, which are critical components for creating permanent, high-integrity connections in piping systems. Unlike threaded fittings, these are welded directly to pipes, offering superior strength and leak resistance, making them ideal for high-pressure and high-temperature applications in industries like oil and gas, petrochemicals, power generation, and shipbuilding. Countries with extensive industrial infrastructure and ongoing energy projects, such as the United States, Saudi Arabia, and India, are significant importers. Leading exporters typically possess advanced metallurgical and manufacturing capabilities, including China, Italy, and Germany. Key considerations in this trade involve adherence to international welding standards (e.g., ASME, ASTM), material grades (e.g., carbon steel, alloy steel), and precise dimensional tolerances to ensure proper fit-up and structural integrity. The demand for these fittings is closely tied to global energy consumption, industrial expansion, and the maintenance of critical infrastructure.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
