HS Code for Carbon steel pipe
Carbon steel pipe of the welded variety is classified under HS code 7306.30. This classification is based on the manufacturing method, the cross-sectional shape, and the material composition. Heading 7306 covers tubes, pipes, and hollow profiles of iron or steel that are welded, riveted, or similarly closed, distinguishing them from the seamless pipes found in heading 7304. For a product to fall under 7306.30, it must be made of iron or non-alloy steel and have a circular cross-section. Furthermore, this code is generally applicable to pipes with an external diameter not exceeding 406.4 mm; pipes larger than this are typically classified under heading 7305. The term "non-alloy steel" refers to steel where the weight of any element does not exceed the limits specified in Note 1(f) to Chapter 72. These pipes are often produced via Electric Resistance Welding (ERW) or Longitudinal Submerged Arc Welding (LSAW). They are used in a wide range of applications, including water distribution, structural support, and low-pressure industrial fluid transport.
Products Included
- ERW (Electric Resistance Welded) carbon steel pipes
- Black steel pipe for plumbing and gas
- Galvanized welded steel pipes (circular)
- Schedule 40 and Schedule 80 welded carbon steel pipes
- Structural carbon steel tubing (circular)
Common Misclassification
The most common misclassification is placing welded pipe under 7304.31 or 7304.39, which are reserved for seamless pipes. Seamless pipes are manufactured through extrusion or piercing and have no longitudinal weld seam. Another error is using 7306.61 for square or rectangular tubing; 7306.30 is strictly for circular cross-sections. Additionally, if the pipe is made of stainless steel, it must be classified under 7306.40. Finally, large-diameter welded pipes (over 406.4 mm) must be moved to heading 7305.
