What HS code 7304 covers

It is where customs puts pipe that was made as one solid piece, with no joint along its length.

The range is wide. It takes in seamless steel pipes for oil and gas work, plain round tubes, and hollow profiles. The six-digit codes split these goods by use, by material and by finish.

HS 7304 six-digit codes by pipe type

Find the pipe type first. Then match the material. Each pair below differs in only one point.

  • 730419 is any other iron or steel.
  • 730423 is any other iron or steel.
  • 730429 is any other iron or steel.
  • 730439 is not.
  • 730449 is not.
  • 730459 is not.
  • 730490 is the catch-all for seamless goods that fit none of the codes above.

How to pick the right 7304 code

Ask these questions in order. Stop when one code fits.

  • Is the pipe made for oil or gas work? If so, check line pipe, drill pipe, and casing and tubing first.
  • What is the material? Stainless, alloy (not stainless) and non-alloy steel each have their own codes.
  • Was it cold-drawn or cold-rolled? This choice splits each round-tube pair.
  • Is the cross-section circular? If it is not, and nothing else fits, 730490 may apply.

HS 7304 vs 7303, 7305, 7306 and 7307

The first test is the seam. Heading 7306 takes pipes and tubes that are not seamless and are not named elsewhere in the chapter. Heading 7305 is also not seamless, but it is only for round pipes with a very large outer diameter.

The second test is the metal. Heading 7303 is for cast iron, so cast iron never goes under 7304.

The third test is whether the item is a pipe at all. Couplings, elbows and sleeves are fittings, and they go under heading 7307. Parts prepared for building structures may fall under heading 7308. If you are still unsure, try the HS code classifier.
