HS Code 7307.99 – Iron or steel; tube or pipe fittings, n.e.c. in item no. 7307.9, other than stainless steel
HS code 7307.99 is the 6-digit subheading for iron or steel, tube or pipe fittings, n.e.c. in item no. 7307.9, other than stainless steel. It is used for flanged steel fittings, socket weld fittings, compression fittings, grooved fittings and victaulic-style fittings.
What HS 7307.99 covers
This "catch-all" HS code for non-stainless iron or steel tube or pipe fittings covers items not specifically classified under threaded or butt-welding types within the 7307.9 subheadings. It includes a diverse range of fittings that might use other connection methods like flanged, socket-weld, or compression, or specialized designs for unique applications. These fittings are vital for completing complex piping systems across various sectors, from industrial manufacturing and chemical processing to water treatment and construction. Importers are typically countries with broad industrial bases and diverse infrastructure needs, such as the United States, Germany, and Japan. Exporters often come from nations with versatile manufacturing capabilities in steel products, including China, India, and various European countries. Understanding the specific connection type, pressure rating, and material grade (e.g., carbon steel, ductile iron) is crucial for accurate classification and trade. This code captures the niche and specialized fittings that ensure the integrity and functionality of fluid conveyance systems globally.

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).
