Linear acting (cylinders)

Hydraulic linear-acting cylinders and similar actuators

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 8412 21 00 (hydraulic 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 — including pneumatic cylinders, hydraulic power packs, or complete hydraulic systems — 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

The principal importer risk at this tariff line is misclassification: hydraulic cylinders forming part of a larger hydraulic or pneumatic system may be re-classified by customs to a more specific line within Chapter 84, triggering retrospective compliance and detention pending resolution. Product documentation should clearly state the actuator type, operating medium (hydraulic fluid), and intended standalone or integrated use before the bill of entry is filed.

Frequently asked

Does HSN 8412 21 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 operates on compressed air rather than hydraulic fluid?

Pneumatic linear-acting cylinders are classified under a separate tariff line within Chapter 84 and should be verified against that line's compliance status before import.
