Linear acting (cylinders)

Pneumatic or hydraulic linear-acting cylinders (actuators)

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 8412 31 00 (linear-acting cylinders) 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 engines and motors under Chapter 84 — particularly those incorporating electrical drives or intended for use in pressure vessels — may fall under sibling tariff lines that carry compliance obligations.

No partner government agency notification covers this tariff line.

A word of counsel

Linear-acting cylinders are classified within the broader 'other engines and motors' heading (8412), and customs re-examination of the precise mechanism — whether pneumatic or hydraulic, combined with an electric motor, or forming part of a pressure system — can shift classification to a line that does carry compliance. Retrospective re-classification triggers detention and potential duty recovery. Ensure the technical specification submitted with the bill of entry accurately describes the actuation medium and intended application.

Frequently asked

Does HSN 8412 31 00 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 cylinder is combined with an electric motor or forms part of a pressure system?

Combined electro-mechanical actuators or cylinders integral to pressure equipment may be classified under a different tariff line within Chapter 84 that attracts its own compliance requirements.
