Pistons

Pistons for spark-ignition internal combustion piston engines

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 8409 91 12 (pistons for spark-ignition internal combustion piston engines) 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 engine parts and assemblies within Chapter 84 — including complete engines under heading 8407 or fuel-injection components — may attract separate compliance requirements.

No partner government agency notification covers this tariff line.

A word of counsel

The absence of compliance at this tariff line applies specifically to pistons classified here; related parts such as piston rings, connecting rods, or cylinder liners may be classified under sibling lines within heading 8409 that carry distinct treatment. Re-classification by customs — for example, from a parts line to a sub-assembly or complete engine line — triggers retrospective compliance and potential detention. Confirm the part's function, material specification, and intended engine type against the customs tariff before import.

Frequently asked

Does HSN 8409 91 12 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 piston is for a compression-ignition engine rather than a spark-ignition engine?

Pistons for compression-ignition internal combustion engines are classified under a different subheading within heading 8409 and must be assessed separately for any applicable compliance requirements.
