Crank shaft for engines of heading 8408
Crankshaft for compression-ignition internal combustion engines
HSN 8483 10 92 (crankshaft for engines of heading 8408) 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 transmission shafts, gearboxes, and mechanical power-transmission components within Chapter 84 may carry product-specific compliance depending on end-use application or the machinery they are designed to serve.
The principal risk at this tariff line is misclassification: crankshafts intended for spark-ignition engines (heading 8407) are classified separately, and a customs officer who re-determines the correct heading triggers retrospective compliance and potential detention pending resolution. Confirm the engine type — compression-ignition versus spark-ignition — against the supplier's technical documentation before filing the bill of entry, as the distinction is the operative basis for tariff-line assignment.
