Gallium nitride epitaxial thin film on substrate

DGFT CLEARANCE

HSN 3818 00 30 (Gallium nitride epitaxial thin film on substrate) is governed by the ITC (HS) import policy administered by the Directorate General of Foreign Trade (DGFT), and import is classified as Free under DGFT Notification 40/2024-25 dated 26-11-2024. No additional sectoral PGA licence or permit is required at the bill-of-entry stage.

Compliance steps

1
Confirm the import policy status at the bill-of-entry stage by referencing DGFT Notification 40/2024-25 dated 26-11-2024, which designates HSN 3818 00 30 as Free under the ITC (HS). No prior licence or permit from DGFT is required, but the CTI and policy status must be correctly declared on the bill of entry.

2
Ensure accurate classification at the 8-digit level. Misclassification to an adjacent CTI within heading 3818 that carries a Restricted or conditional policy status would trigger an incorrect duty and policy enforcement; verify the substrate type and epitaxial process against the tariff descriptor before filing.

A word of counsel

The single most common error on this tariff line is misclassification — filing under a neighbouring 3818 CTI (for example, a silicon-doped wafer or compound semiconductor disc) rather than the specific gallium nitride epitaxial thin film entry. A misclassification to a Restricted CTI within the same heading triggers an ITC (HS) policy bar, consignment detention, and potential re-export, even though the correctly classified product imports freely under DGFT Notification 40/2024-25.

Frequently asked

Does HSN 3818 00 30 require BIS certification?

No. No BIS Quality Control Order covers gallium nitride epitaxial thin films. Import of this product is Free under the ITC (HS) policy as per DGFT Notification 40/2024-25 dated 26-11-2024, with no BIS licence, registration, or conformity-assessment requirement applicable.

Was HSN 3818 00 30 previously restricted or subject to a prior condition before DGFT Notification 40/2024-25?

The regulatory record records the current Free status as established by DGFT Notification 40/2024-25 dated 26-11-2024; importers should verify any prior policy history directly with DGFT for goods shipped or contracted before that date.

Are any other regulatory approvals or end-use certificates required for import of GaN epitaxial substrates used in defence or aerospace applications?

The ITC (HS) import policy for HSN 3818 00 30 is Free with no end-use condition recorded in the regulatory record; however, downstream use in defence or dual-use applications may attract separate export-control or SCOMET-related obligations under DGFT policy that should be assessed at the transaction level.
