Special Economic Zones (SEZs) in India operate as deemed foreign territory for customs purposes — meaning imports into an SEZ are treated differently from regular domestic imports. Whether you are an SEZ unit importing from abroad or a DTA supplier shipping goods into an SEZ, the bill of entry rules are distinct and require specific documentation.

What Is an SEZ for Customs Purposes?

Under the Special Economic Zones Act, 2005 and SEZ Rules, 2006, an SEZ is treated as a port of import for customs purposes. Goods entering an SEZ from:

Importing Directly into an SEZ from Abroad

When an SEZ unit imports goods directly from a foreign country, the bill of entry is filed at the SEZ customs authority (each SEZ has a designated Development Commissioner and customs officer). Key differences from regular imports:

DTA Supplier Sending Goods to an SEZ

When a domestic business (DTA) supplies goods to an SEZ unit, it is treated as a deemed export. The DTA supplier:

  1. Issues a tax invoice and marks it as "Supply to SEZ under Bond/LUT"
  2. Files GST Form GSTR-1 with the SEZ supply details
  3. Can supply with zero-rated GST (under LUT) or with IGST (and claim refund)
  4. May claim duty drawback on the central excise / customs component through the ARE-1 process

SEZ Unit Sending Goods to DTA (SEZ to DTA Sale)

This is effectively an import into India from a deemed foreign territory. The DTA buyer must:

  1. File a bill of entry as if importing from abroad
  2. Pay applicable basic customs duty and IGST on the transaction value
  3. Claim IGST as ITC if registered under GST

Frequently Asked Questions

Do SEZ units pay GST on imports?

No — SEZ units are exempt from IGST on imports of goods and services used for authorized operations. Capital goods and raw materials imported by SEZ units are duty-free under Section 26 of the SEZ Act.

Can a DTA buyer claim ITC on purchases from an SEZ?

Yes, if the SEZ unit charges IGST on the sale, the DTA buyer can claim ITC. However, since SEZ-to-DTA is treated as import, the bill of entry IGST is the claimable document, not a regular tax invoice.

What happens if an SEZ unit uses duty-free imports for DTA supply?

The SEZ unit must pay full customs duty plus interest on any duty-free imported goods that are diverted to DTA use. This is a serious compliance issue and is monitored through annual verification.
