Transmission shafts, cam shafts, crank shafts, and cranks
HSN 8483 10 99 (Other transmission shafts — including cam shafts, crank shafts, and cranks) 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. Shafts and cranks classified as parts of specific machinery — engines, compressors, or vehicles — may fall under a more specific tariff line in Chapter 84 or Chapter 87 that carries its own compliance regime.
The principal risk at this tariff line is misclassification: cam shafts and crank shafts supplied as dedicated parts for internal combustion engines or automotive applications are frequently re-classified by customs to the relevant machinery or vehicle parts heading. A re-classification on examination triggers retrospective compliance obligations and detention pending resolution. Verify the product's intended use and the contractual description against the customs tariff — particularly whether the shaft is a general-purpose power-transmission component or a dedicated engine or vehicle part.
