What HS code 7303 covers
The Harmonized System, or HS, is a world list of codes for traded goods. The World Customs Organization looks after it. An HS heading is the first four digits of a code. A hollow profile is a long piece with an empty centre.
The material is what puts a product here. If the pipe is made of cast iron, think of 7303. If it is made of other iron or of steel, you will probably need a different heading. The next sections show which ones.
Customs officers, freight agents and traders all use this code. It tells them what is in the box before anyone opens it. It also lets them group shipments of the same kind of goods, in any country that follows the WCO nomenclature.
HS code 730300 and the six-digit subheading
A six-digit subheading splits a heading into smaller parts. Heading 7303 has no such split. All goods in it share one six-digit subheading, 730300.
Countries are free to add more digits after those six. They do this for their own tariff and statistics needs. These longer national codes always start with 730300, but their extra digits can differ from one country to the next. Always check the code your own customs office uses before you file.
If you are unsure, try the HS code classifier. It helps you test a product description against the code list.
Cast iron pipes vs steel pipes: 7303, 7304, 7305 and 7306
Many buyers mix up 7303 with the steel pipe headings that sit next to it. The simple rule is to ask two questions. Is the pipe cast iron? Use the list below to sort your product.
- This is the key difference between HS 7303 and 7304: the material and the seamless build.
- 7306: other tubes, pipes and hollow profiles of iron or steel, not cast iron, that are not seamless and are not named elsewhere in Chapter 73.
- A fitting joins pipes. It is not a pipe itself.
- 7325: other cast articles of iron or steel. If a cast iron product is not a tube, pipe or hollow profile, look here.
