Grinding wheels and stones of agglomerated diamond, other types

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 6804 21 90 (grinding wheels and similar tools of agglomerated synthetic or natural diamond, other than those mounted on frameworks) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code, bill of entry, commercial invoice, packing list. Other abrasive tools within Chapter 68 — particularly grinding wheels of agglomerated non-diamond abrasives or ceramics — may fall under sibling tariff lines with distinct classification consequences.

No partner government agency notification covers this tariff line.

A word of counsel

The principal risk at this tariff line is misclassification: diamond abrasive tools mounted on frameworks, or tools combining diamond with non-diamond bonding matrices, may be classified differently within Chapter 68 or under Chapter 82 (hand tools and tool parts), each carrying its own duty and compliance treatment. A customs re-classification on examination triggers retrospective duty recovery and potential detention pending resolution. Confirm the precise bonding type, diamond content, and mounting configuration against the customs tariff before import.

Frequently asked

Does HSN 6804 21 90 require any pre-import registration?

A valid Importer-Exporter Code is required for any commercial import; no product-specific registration applies to this tariff line.

What changes if the grinding wheel uses non-diamond abrasives or is made of ceramics?

Non-diamond abrasive or ceramic grinding wheels fall under separate subheadings within Chapter 68 and should be verified against the customs tariff, as classification differences may affect applicable duty rates.
