Plain-language overview

Use HS-6 730640 when importing or exporting welded stainless steel tubes and pipes with a circular cross-section. For example, if you're shipping a batch of stainless steel pipes used in plumbing systems, this is the correct code.

This code specifically covers welded tubes and pipes made from stainless steel, which distinguishes them from other materials like carbon steel or cast iron. For instance, if you have a shipment of carbon steel pipes, you would need a different classification under this heading.

If you’re dealing with seamless stainless steel tubes, you would classify those under a different HS code. HS-6 730640 is strictly for welded varieties, so ensure you check the specifics of your product before proceeding.

Understanding the nuances between this code and others in the same heading is crucial. For example, HS-6 730630 covers non-welded stainless steel tubes, which would not apply if your product is welded.
