Lapping machines

Lapping machines for finishing metal or cermets

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 8460 40 20 (lapping machines) 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 (IEC), bill of entry, commercial invoice, packing list. Other machine-tools under Chapter 84 — particularly numerically controlled grinding or gear-finishing machines — may be classified under sibling tariff lines that carry distinct compliance requirements.

No partner government agency notification covers this tariff line.

A word of counsel

The principal risk at this tariff line is misclassification: lapping machines share Chapter 84 with honing machines (the sibling 6-digit subheading 8460 40), grinding machines, and gear-finishing machines under heading 8461, and customs re-classification to a more specific tariff line triggers retrospective compliance and potential detention. Importers should confirm that the machine's primary finishing action — lapping, using charged laps or abrasive slurries — is accurately described in the technical specification and bill of entry before shipment.

Frequently asked

Does HSN 8460 40 20 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 machine performs honing rather than lapping?

Honing machines fall under the same 6-digit subheading (8460 40) but a different 8-digit line, and any compliance obligations must be verified independently for that classification.
