Diamond impregnated wheels
Diamond impregnated grinding wheels, agglomerated synthetic or natural diamond
HSN 6804 21 10 (Diamond impregnated wheels) 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 wheels and grinding tools classified elsewhere in Chapter 68 — particularly those of agglomerated non-diamond abrasives or ceramics — may attract distinct classification treatment depending on composition and intended use.
Diamond impregnated wheels shade into closely related tariff lines depending on bond type, grit specification, and whether the wheel is mounted or unmounted — details that customs examination can resolve against the importer's favour. Re-classification to a sibling line within heading 6804 or to a related abrasives heading can trigger retrospective duty recovery and detention pending resolution. Confirm the precise bond matrix, diamond concentration, and intended industrial application against the tariff descriptor before shipment.
