HS Code 7307.23 – Steel, stainless; tube or pipe fittings, butt welding fittings

HS code 7307.23 is the 6-digit subheading for steel, stainless, tube or pipe fittings, butt welding fittings. It is used for stainless steel butt-weld elbows, stainless steel butt-weld tees, stainless steel butt-weld reducers, stainless steel butt-weld caps and stainless steel butt-weld crosses.

What HS 7307.23 covers

This HS code specifically covers butt-welding fittings made from stainless steel, which are designed to be welded directly to pipes, creating a permanent, leak-proof connection. These fittings are essential for constructing high-integrity piping systems in critical applications where strength, corrosion resistance, and flow efficiency are paramount. Industries such as oil and gas, petrochemicals, power generation, and chemical processing heavily rely on these fittings for their robust performance under extreme conditions. Importers are typically large-scale industrial project contractors, engineering procurement construction (EPC) firms, and specialized distributors globally. Exporters are often found in countries with advanced steel manufacturing and fabrication capabilities. Key trade considerations include material grade (e.g., 304/304L, 316/316L), wall thickness schedule, dimensional accuracy, and compliance with international standards like ASME B16.9.

Codes often confused with 7307.23

Common mistake. Can be confused with threaded fittings (730722) or flanges (730721) if the specific 'butt-welding' connection method is not clearly identified, leading to incorrect classification.

Top exporters and importers of HS code 730723, 2025

In 2025, the largest exporter of HS code 730723 in UN Comtrade data was China, with 23% of world exports; the largest importer in UN Comtrade data was the United States, with 12% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
