HS Code 2510Natural calcium phosphates; natural aluminium calcium phosphates and phosphatic chalk

What HS code 2510 covers

The heading name lists three goods. The word natural matters. It points to minerals that come from nature, not to products made in a chemical plant.

Chapter 25 mineral products are mostly raw or lightly worked materials, such as earths, stone and lime.

You may also see this heading written as HSN code 2510 or HTS 2510. The first four digits are the same in each list. Individual countries may add extra digits after the six-digit level, so always check the rule in the country you ship to.

HS 251010 vs 251020: unground or ground

Only one thing separates the two codes. It is the state of the material. HS 251010 is for unground goods. HS 251020 is for ground goods.

Unground means the material has not been milled or crushed into powder. If your shipment is raw material as it left the mine, look at 251010. If it is a milled powder, look at 251020.

The same split applies to all three goods in the heading. The rule is the same for aluminium calcium phosphates and for phosphatic chalk.

• Ask your supplier if the goods were milled before they were loaded.
• Use the same code on the invoice, packing list and customs form.
• If a lot is part ground and part unground, check how your customs office treats mixed lots.

Headings to rule out in Chapter 25

Some nearby headings sound close but cover other goods. Phosphatic chalk is named in heading 2510, so it stays here. Plain chalk goes to heading 2509.

Barium minerals such as barytes go to heading 2511. Siliceous fossil meals, such as diatomite, go to heading 2512. These are different minerals with their own rules.

Heading 2530 is for mineral substances that are not named anywhere else. Use it only after you have ruled out every specific heading, including 2510. If a product is hard to place, run its description through the classifier.
