Gear shaper, spur and helical
Gear shaper machines for spur and helical gears
HSN 8461 40 25 (gear shaper, spur and helical) 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 within Chapter 84 — particularly numerically controlled or CNC variants — may fall under sibling tariff lines that carry distinct classification consequences.
The principal risk at this tariff line is misclassification: gear grinding, gear finishing, and CNC-controlled gear cutting machines are each separately enumerated within heading 8461, and customs re-classification to a more specific sub-heading triggers retrospective duty recovery and potential detention. Confirm that the machine's operating principle — shaping by reciprocating cutter — and its gear-profile type (spur or helical) are accurately reflected in the technical specification submitted with the bill of entry.
