Flexible coupling

Flexible couplings for shaft power transmission

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 8483 60 10 (Flexible coupling) 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 mechanical power-transmission components within Chapter 84 — such as gearboxes, torque converters, or clutch assemblies — may be classified under distinct tariff lines that carry separate compliance obligations.

No partner government agency notification covers this tariff line.
A word of counsel

Flexible couplings are precision mechanical components, and the correct tariff line depends on design and function: a jaw coupling, disc coupling, or gear coupling may each be described as 'flexible' yet differ in classification risk if customs re-characterises the assembly as a clutch or a universal joint within the same heading. Re-classification on examination triggers retrospective compliance and potential detention. Confirm the product's functional description and engineering specification against the customs tariff before shipment.

Frequently asked
Does HSN 8483 60 10 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 coupling is classified as a clutch or universal joint instead of a flexible coupling?
Clutches and universal joints sit within the same subheading 8483 60 but under distinct 8-digit lines, and any such re-classification by customs may trigger retrospective compliance obligations applicable to that specific tariff line.
