HS Code for Natural corundum

Natural corundum, along with emery and natural garnet, is classified under HS code 2513.20. This classification is situated within Chapter 25, which covers mineral products used primarily for industrial purposes. Heading 2513 includes pumice stone and various natural abrasives. Subheading 2513.20 specifically addresses emery, natural corundum, and natural garnet. These materials are characterized by their extreme hardness—corundum ranks 9 on the Mohs scale—and are used extensively in grinding, polishing, and abrasive blasting. The classification applies even if the minerals have been heat-treated to improve their abrasive properties or color, provided they remain in their natural mineral form and are not of gem quality. It is important to distinguish these industrial-grade minerals from gem-quality corundum, such as rubies and sapphires. The industrial application and natural origin are the defining factors for 2513.20. This code covers the mineral in its crude form, as well as when it has been crushed or ground into grains or powder for use in abrasive papers or grinding wheels. The classification ensures that natural industrial abrasives are distinguished from synthetic alternatives.

Products Included

• Natural corundum (non-gem grade)
• Emery
• Natural garnet
• Crushed natural abrasives
• Heat-treated natural corundum grains

Common Misclassification

Natural corundum is most frequently misclassified as artificial corundum (synthetic aluminum oxide), which is classified under HS code 2818.10. Another critical distinction is with gem-quality corundum (rubies and sapphires), which must be classified under heading 7103. If the corundum is already bonded onto a backing (like sandpaper), it moves to heading 6805.

FAQ

What is the HS code for natural corundum?

The HS code for natural corundum, emery, and natural garnet is 2513.20.

Are rubies classified under the same HS code as natural corundum?

No, while rubies are a form of corundum, gem-quality stones are classified under HS code 7103, whereas industrial natural corundum is 2513.20.
