Customs code · HS subheading 7305 31

Final code reached

Large-diameter longitudinally welded iron or steel pipes

Over 406.4 mm, not for oil or gas pipelines or extraction

This is a complete 8-digit customs code. Exports and Intrastat use it as it is. For an import into the EU the declaration uses 7305 31 00 00: this code with 00 added.

This code covers non-seamless pipes with a circular cross-section made of iron or steel, with an outside diameter over 406.4 mm and a longitudinal weld. It excludes pipes of the kind used for oil or gas pipelines or for extracting oil and gas.

For example

  • A longitudinally welded iron pipe with a circular cross-section and an outside diameter over 406.4 mm, for a use other than oil or gas pipelines or oil and gas extraction
  • A longitudinally welded steel pipe with a circular cross-section and an outside diameter over 406.4 mm, for a use other than oil or gas pipelines or oil and gas extraction

Before you use the code

Check the facts that sit outside the code

The code can be right while what you pay still changes, because of where the goods come from, when they arrive, or extra EU measures.

Classify your own product, free Look up the current rates and rules
  1. The product and its form Check that your product really matches this description, including what it is made of and the form it arrives in.
  2. Country of origin Trade agreements, sanctions and extra measures can change the treatment of the very same code.
  3. Current tariff measures Check today's rate, any restrictions or licences, and the quantity customs asks for, with Toldstyrelsen or TARIC.
