HS Code 7306.11 – Steel; stainless; line pipe of a kind used for oil or gas pipelines n.e.c. in chapter 73, welded, (not seamless)
HS code 7306.11 is the 6-digit subheading for steel, stainless, line pipe of a kind used for oil or gas pipelines n.e.c. in chapter 73, welded, (not seamless). It is used for stainless steel sour gas pipelines, offshore stainless steel risers, chemical process pipelines, high-pressure stainless steel oil lines and refinery transfer pipes.
What HS 7306.11 covers
This code specifically covers welded stainless steel line pipe used for oil or gas pipelines, which are not seamless and fall under the "not elsewhere specified" within Chapter 73. These pipes are critical components in the energy sector, particularly where corrosion resistance is paramount due to the nature of the transported fluids (e.g., sour gas, corrosive crude oil) or environmental conditions. Key importers and exporters are countries with significant oil and gas production, refining, and transportation infrastructure, such as the USA, Canada, Saudi Arabia, Russia, and various European nations. The trade is driven by new pipeline construction, maintenance, and upgrades in challenging environments. Buyers include oil and gas exploration and production companies, pipeline operators, and engineering, procurement, and construction (EPC) firms. The "stainless steel" aspect is crucial, distinguishing these pipes from standard carbon steel pipes, offering enhanced durability and longevity in demanding applications.

Codes often confused with 7306.11
Common mistake. This code is often confused with 730619 (non-stainless line pipe) or 730411 (seamless stainless line pipe) due to similar applications, but the key differentiators are the material (stainless steel), welding (welded), and specific use (oil/gas line pipe).
Top exporters and importers of HS code 730611, 2025
In 2025, the largest exporter of HS code 730611 in UN Comtrade data was China, with 59% of world exports; the largest importer in UN Comtrade data was the United Arab Emirates, with about 19% 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).
