Natural calcium phosphates, natural aluminum calcium phosphates and phosphatic chalk
2 declarable lines
Heading 2510 covers natural calcium phosphates, natural aluminum calcium phosphates and phosphatic chalk, which are phosphate-bearing minerals used mainly for fertilizer production and industrial filler. The heading is split by physical form into two lines: unground material in 2510.10.00.00 and ground material in 2510.20.00.00. Both lines carry a general (MFN) rate of Free.
Products in this heading

- Apatite mineral concentrate of natural origin
How to choose the right subheading
- Confirm the material is a natural calcium phosphate, natural aluminum calcium phosphate or phosphatic chalk, not a processed chemical.
- Determine whether the goods are in unground form, which falls in 2510.10.00.00.
- Determine whether the goods have been ground, which falls in 2510.20.00.00.
- Check that the product is not mixed with other nutrients or put up as a fertilizer of chapter 31.
- Check that the mineral has not been calcined or chemically treated.
Often confused with
- Heading 3105Ground phosphate rock mixed with other fertilizer nutrients or made up as a fertilizer product
Mixtures and packaged fertilizer goods of chapter 31 are classified there, not as raw mineral.
- Heading 2835Calcined or chemically treated phosphates such as dicalcium phosphate
Chemically processed phosphates are separate chemical compounds of chapter 28.
- Heading 2511Natural barium sulfate (barytes)
Barium minerals have their own heading in chapter 25.
- Heading 2505Natural sands of all kinds
Sand, even calcareous sand, is classified as natural sand.
- Heading 2517Crushed limestone or chalk used as aggregate
Stone crushed for concrete, road metalling or ballast goes to the aggregates heading.
