Product classification
HS code for Stainless steel elbows: 7307.22
Steel, stainless, tube or pipe fittings, threaded elbows, bends and sleeves.
Classification of stainless steel elbows under HS 7307.22
Stainless steel elbows are classified under HS code 7307.22. This code falls under Chapter 73, which covers articles of iron or steel, and heading 7307, which covers tube or pipe fittings. Subheading 7307.22 is specific to threaded elbows, bends, and sleeves made of stainless steel. The classification distinguishes between different types of fittings based on their method of connection and their material. For an item to fall under 7307.22, it must be made of stainless steel and feature threads for connection. If the elbow is designed for butt-welding rather than threading, it would be classified under subheading 7307.23. This precise categorization ensures that trade statistics and tariff applications are accurate for specific industrial components. Elbows are used to change the direction of flow in a piping system, typically at 45 or 90-degree angles. The "threaded" requirement is a key determinant for this specific code, as it excludes fittings that are joined by other means. The material must meet the definition of stainless steel as provided in the Chapter 72 notes, which require a minimum chromium content of 10.5% and a maximum carbon content of 1.2%.

Codes often confused with 7307.22
Common mistake. The most common misclassification is confusing 7307.22 with 7307.23. The latter is for butt-welding fittings, which do not have threads. Another error is using 7307.29, which is a residual category for "other" stainless steel fittings that are neither flanges, threaded elbows/sleeves, nor butt-welding fittings. Additionally, elbows made of carbon steel or other non-stainless alloys must be classified under 7307.92, not 7307.22.

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).
