DGFT CLEARANCE

HSN 8483 40 00 (Gear boxes and other speed changers, including ball or roller screws) is governed by the ITC (HS) import policy administered by the Directorate General of Foreign Trade (DGFT), with imports classified as Free subject to policy condition no. 5 of Chapter 84. Where the imported gear boxes or ball screws have an end-use in wind-operated electricity generation, mandatory prior registration on the Renewable Energy Equipment Import Monitoring System (REEIMS) of the Ministry of New and Renewable Energy is required under DGFT Notification 40/2025-26.

Compliance steps

1
Determine whether the imported gear boxes or ball or roller screws are destined for wind-operated electricity generation. If yes, register on the REEIMS portal of the Ministry of New and Renewable Energy before shipment — at least five days in advance for sea and land route cargo and at least two days in advance for air cargo.
DGFT Notification 40/2025-26 dated 10-10-2025 · Policy condition no. 5 of Chapter 84
2
Ensure the REEIMS registration is current: each registration is valid for three months, is specific to a designated seaport, airport, or land port, and carries no registration fee. Multiple consignments may be cleared under a single registration provided the port designation matches the bill of entry.
DGFT Notification 40/2025-26 dated 10-10-2025
3
File the end-use declaration for the imported products or components as required under the REEIMS portal at the time of registration. Where wind-energy end-use does not apply, the import proceeds as Free under the ITC (HS) policy without REEIMS registration, but the importer should retain documentary evidence of the non-wind end-use to address any customs query.

A word of counsel

The critical error on this tariff line is importing gear boxes or ball screws for wind-energy projects without completing REEIMS registration before dispatch. The policy condition applies across all modes — air, sea, and land — and the advance-registration window (five days for sea/land, two days for air) means a last-minute registration attempt after vessel departure will leave the consignment without a valid registration at the bill-of-entry stage, attracting detention and potential ITC (HS) Restricted-policy enforcement despite the Free base status.

Frequently asked

Does HSN 8483 40 00 require BIS certification?

No, gear boxes and speed changers under this tariff line are not covered by any BIS Quality Control Order. Import is governed by the ITC (HS) policy administered by the Directorate General of Foreign Trade, with REEIMS registration required solely where the end-use is wind-operated electricity generation under DGFT Notification 40/2025-26.

Is REEIMS registration required for all imports of HSN 8483 40 00, or only for wind-energy applications?

Registration on REEIMS is required only where the items under HSN 8483 40 00 have an end-use in wind-operated electricity generation. Imports for other industrial or mechanical applications are Free under the ITC (HS) policy without a REEIMS obligation, subject to the importer being able to evidence the non-wind end-use.

How long does a REEIMS registration remain valid, and can it cover multiple shipments?

Each REEIMS registration is valid for three months from the date of issue and is specific to a designated seaport, airport, or land port; multiple consignments may be processed under a single registration provided the port of import matches the registered designation.
