HS code · 6-digit subheading
HS Code 7306.50 – Steel, alloy; tubes, pipes and hollow profiles (other than stainless steel or seamless), welded, of circular cross-section, n.e.c. in chapter 73
HS code 7306.50 is the 6-digit subheading for steel, alloy, tubes, pipes and hollow profiles (other than stainless steel or seamless), welded, of circular cross-section, n.e.c. in chapter 73. It is used for boiler tubes, automotive exhaust components, hydraulic cylinder tubing, high-pressure steam pipes and mining equipment structural tubes.
What HS 7306.50 covers
This HS code pertains to welded tubes, pipes, and hollow profiles made from alloy steel (excluding stainless steel), with a circular cross-section. These products are traded internationally for applications requiring specific material properties beyond those of standard carbon steel, such as enhanced strength, heat resistance, or wear resistance. Importers are typically manufacturers in power generation, automotive, heavy machinery, and specialized construction sectors that demand materials tailored for extreme operating conditions. Exporters are nations with sophisticated metallurgical industries capable of producing specialized alloy steels. Key trade factors include the specific alloying elements (e.g., chromium, molybdenum), required heat treatments, and adherence to application-specific performance standards, which dictate their suitability for demanding engineering tasks.

Codes often confused with 7306.50
Common mistake. Can be confused with 730630 (non-alloy steel) if the alloy content is minor or overlooked, or 730690 (other tubes) if the cross-section isn't strictly circular or the alloy type is ambiguous.
Top exporters and importers of HS code 730650, 2025
In 2025, the largest exporter of HS code 730650 in UN Comtrade data was Germany, with 21% of world exports; the largest importer in UN Comtrade data was Mexico, 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 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).
