What HS code 25 covers

Chapter 25 is about minerals in their natural or lightly worked state. It starts with salt and sulphur. It then runs through sands, clays and chalk, and on to stone, lime and cement. Industrial minerals such as mica, talc, feldspar and fluorspar sit at the end.

Most goods here are raw, crushed, cut or calcined. When a material is worked further, it often moves to a different chapter. That is why the exact wording of each heading matters.

Salt HS code in Chapter 25: heading 2501

Salt has its own heading, 2501. The wording is wide. It covers table salt and denatured salt. It covers pure sodium chloride, whether or not it is dissolved in water. It also covers sea water.

The heading holds one six-digit code, 250100, so the heading and the code carry the same text. The code does not split edible salt from industrial salt. If you ask how to tell them apart, start from the product itself and the exact words of the heading, then check the rules of the country you ship to.

HS code for marble, granite, gypsum and portland cement

Stone and binders are the busiest part of the chapter. These are the headings most people look for.

For stone, the form of the goods decides the code. Blocks and slabs sit in the stone headings. Crushed material sits in 2517.

  • 2515: marble, travertine and alabaster.
  • 251611 is crude granite. 251612 is cut granite. 251620 is sandstone.
  • 2520: gypsum, anhydrite and plasters.
  • 2523: cement. 252310 is cement clinker. 252321 is white portland cement. 252329 is portland cement other than white.

How to choose the right Chapter 25 code

Read the heading text first, then the six-digit lines under it. Ask what the goods are, what form they are in, and whether they have been worked.

For stone, compare 2515, 2516 and 2517. Marble and travertine go to 2515. Granite and sandstone go to 2516. For binders, compare 2520, 2522 and 2523: gypsum and plasters, lime, and cement. For clays, kaolin has its own heading, 2507. Other clays, such as bentonite and fireclay, fall under 2508.

Some goods are pushed out of this chapter. Expanded clays belong to heading 6806, not 2508. Barium oxide belongs to 2816, not 2511. Calcium oxide and hydroxide belong to 2825, not 2522.

HS Chapter 25: common questions

What does HS chapter 25 cover?

It is the chapter for natural minerals that are raw, crushed, cut or calcined. Salt, stone, gypsum and cement are typical examples.

What is the HS code for salt?

Salt falls under heading 2501, and its single six-digit code is 250100. Open the heading page to see how it is described.

Does HS 2501 include sea water and salt solutions?

Yes. The heading covers pure sodium chloride whether or not it is in aqueous solution. Sea water is named in the heading text too.

What is the HS code for portland cement?

Portland cement is in heading 2523. Use 252321 for white cement and 252329 for other portland cement. Cement clinker has its own code, 252310.

What is the HS code for marble and granite slabs?

Marble is in heading 2515, with 251511 for crude or roughly trimmed and 251512 for merely cut. Granite is in heading 2516, with 251611 and 251612 for the same two forms.

What is the difference between Chapter 25 and Chapter 26 ores?

Chapter 26 covers ores, slag and ash. Chapter 25 covers earths, stone and other minerals. Heading 2505 leaves out metal-bearing sands, which go to Chapter 26.
