HS-4 · Heading

2519Natural magnesium carbonate (magnesite); fused magnesia; dead-burned (sintered) magnesia, whether or not containing small quantities of other oxides added before sintering; magnesium oxide, pure or not

Chapter 25: Salt; sulphur; earths and stone

Plain-language overview

Use HS-4 2519 when importing natural magnesium carbonate, commonly found in products like magnesite. For example, if you're shipping a bulk load of magnesite for industrial use, this code applies directly.

When deciding between the HS-6 lines, consider that 251910 specifically covers natural magnesium carbonate. If your product is pure magnesite, this is the correct classification. In contrast, 251990 includes fused or dead-burned magnesia, which may contain other oxides and is not classified as natural.

If your shipment includes processed magnesia, such as sintered magnesia used in refractory materials, you’ll want to use 251990. This line captures products that have undergone additional processing compared to the natural form in 251910.
