Silicon carbide epitaxial thin film on substrate

DGFT CLEARANCE

HSN 3818 00 20 (Silicon carbide epitaxial thin film on substrate) is governed by the ITC (HS) import policy administered by the Directorate General of Foreign Trade (DGFT), under which import is classified as Free per DGFT Notification 40/2024-25 dated 26-11-2024. No licence or permit is required at the bill-of-entry stage beyond standard customs documentation.

Compliance steps

1
Confirm the import policy status as Free under the ITC (HS) schedule at the time of filing the bill of entry. The Free status for silicon carbide epitaxial thin film on substrate was confirmed by DGFT Notification 40/2024-25 and no import licence or DGFT authorisation is required.
DGFT Notification 40/2024-25 dated 26-11-2024
2
Ensure the bill of entry correctly describes the product as silicon carbide epitaxial thin film on substrate under CTI 3818 00 20. Misclassification into an adjacent doped-semiconductor or chemical-compound heading may attract a different import policy condition and delay customs out-of-charge.

A word of counsel

The single most consequential error on this tariff line is misclassification: silicon carbide wafers and substrates without an epitaxial layer may fall under a different CTI with a distinct import policy condition. Confirm that the product description on the commercial invoice and packing list explicitly states 'epitaxial thin film on substrate' before filing; a mismatch in the product descriptor can trigger re-assessment and potential detention pending classification resolution.

Frequently asked

Does HSN 3818 00 20 require BIS certification?

No, no BIS Quality Control Order covers silicon carbide epitaxial thin film on substrate. Import is governed solely by the ITC (HS) import policy administered by the Directorate General of Foreign Trade, under which this CTI carries a Free import status per DGFT Notification 40/2024-25.

Is an import licence from DGFT required for this tariff line?

No. The import policy for CTI 3818 00 20 is Free as per DGFT Notification 40/2024-25 dated 26-11-2024, meaning no licence, authorisation, or permit from DGFT is required at the bill-of-entry stage.

What distinguishes HSN 3818 00 20 from other doped-semiconductor headings in Chapter 38?

HSN 3818 00 20 covers silicon carbide specifically in epitaxial thin-film form on a substrate; bare silicon carbide wafers or other doped chemical elements in disc or wafer form without an epitaxial layer classify under different eight-digit CTIs, which may carry separate policy conditions.
