HS Code for Steel flanges
Steel flanges are categorized under HS code 7307.91. This code is situated within Heading 7307, which encompasses tube or pipe fittings of iron or steel. The classification distinguishes between different types of fittings (such as couplings, elbows, and sleeves) and different material compositions. Subheading 7307.91 is specifically reserved for flanges made of iron or non-alloy steel, excluding stainless steel. Flanges are essential components used to connect pipes, valves, pumps, and other equipment to form a piping system. They provide easy access for cleaning, inspection, or modification. The classification depends heavily on the metallurgical properties of the steel. If the flange contains more than 10.5% chromium, it would likely be reclassified as stainless steel under 7307.21. Furthermore, the classification assumes the product is a finished or semi-finished fitting ready for installation in a piping network. The distinction between cast and non-cast fittings is also vital, as cast iron fittings fall under 7307.11 or 7307.19. For 7307.91, the product is typically forged or machined from carbon steel.
Products Included

Common Misclassification
The most frequent misclassification occurs between 7307.91 (non-alloy steel flanges) and 7307.21 (stainless steel flanges). Customs authorities strictly enforce the material composition; any flange meeting the definition of stainless steel must be moved to the 7307.2x series. Another common error is confusing flanges with other pipe fittings like elbows or tees, which are classified under 7307.92 or 7307.99. Finally, cast iron flanges are often incorrectly placed here instead of under 7307.19, which covers cast articles of iron or steel.
