HS-6 · Subheading
730431
Iron or non-alloy steel (excluding cast iron); seamless, cold-drawn or cold-rolled, tubes, pipes and hollow profiles of circular cross-section
Heading 7304 — Tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel
Chapter 73: Articles of iron or steel
Plain-language overview
Use HS-6 730431 when importing or exporting seamless tubes and pipes made of non-alloy iron or steel. For instance, if you're shipping a batch of cold-drawn steel pipes for construction, this code applies.
This code specifically covers seamless, cold-drawn or cold-rolled tubes and pipes with a circular cross-section. It differs from HS-6 7304XX, which includes welded tubes and pipes, making it essential to choose the right classification based on your product's manufacturing process.
If you're dealing with seamless pipes that are not made from cast iron, this is the right classification. In contrast, HS-6 730432 pertains to alloyed steel tubes, which have different properties and applications.
When considering the HS-6 code, think about the end-use of the product. Seamless tubes are often used in industries like oil and gas, construction, and automotive, where strength and reliability are crucial.
