A Special Economic Zone (SEZ) is a duty-free enclave treated as foreign territory for trade operations under the SEZ Act 2005. A unit gets duty-free import and DTA procurement, zero-rated GST supplies and single-window clearance, against a positive Net Foreign Exchange obligation over five years.
Overview
An SEZ is a specifically delineated, duty-free enclave deemed to be foreign territory for the purposes of trade operations, duties and tariffs. The regime is governed by the Special Economic Zones Act, 2005 and the SEZ Rules, 2006, administered by the Department of Commerce through a Development Commissioner for each zone. Goods and services going into an SEZ from the Domestic Tariff Area (DTA) are treated as exports, and goods coming out into the DTA are treated as imports.
Legal Basis
The core enactment is the SEZ Act 2005, supported by the SEZ Rules 2006. Customs treatment flows from Section 51 of the SEZ Act, which gives the Act overriding effect, read with the Customs Act 1962 for assessment on DTA clearance. The income-tax benefit was routed through Section 10AA of the Income-tax Act. GST treatment comes from Section 16 of the IGST Act, which makes supplies to an SEZ developer or unit "zero-rated".
Setting Up a Unit — Step by Step
- Choose a zone and confirm the sector is permitted there.
- File Form F (application for setting up a unit) with the Development Commissioner, with a project report and NFE projection.
- Unit Approval Committee considers the proposal and issues the Letter of Approval (LoA), generally valid for five years.
- Execute a Bond-cum-Legal Undertaking (BLUT) with the Development Commissioner and Specified Officer (Customs).
- Obtain registrations — GST, IEC from DGFT, and lease the built-up space or plot inside the processing area.
- Commence operations and begin filing periodic reports.
Benefits
- Duty-free import and domestic procurement of capital goods and inputs, without payment of Basic Customs Duty and IGST at the point of entry into the zone.
- Zero-rated GST on supplies received from the DTA, so DTA suppliers can supply under LUT or claim refund.
- Single-window clearance and self-certification of goods within the zone.
- Income-tax deduction under Section 10AA — but note the sunset: only units that began manufacture/service before 1 April 2020 enjoy it (100% of export profit for 5 years, 50% for the next 5, and a further reinvestment-linked 50% for 5 years). Verify current position for your unit.
Net Foreign Exchange Obligation
Under Rule 53 of the SEZ Rules, a unit must be a net foreign exchange earner, computed cumulatively for a block of five years from commencement. Broadly, NFE = A − B, where A is FOB value of exports and B is the CIF value of imports and other specified outflows. If, say, a unit exports goods of ₹40 crore and imports inputs of ₹22 crore over the block, its NFE is a positive ₹18 crore, satisfying the obligation.
DTA Sale and Exit
An SEZ unit may sell finished goods into the DTA on payment of applicable customs duties, treated as an import by the DTA buyer, provided NFE stays positive. On exit, the unit surrenders the LoA, pays duties on unutilised imported capital goods and inputs on the depreciated/transaction value, and gets a No-Dues certificate.
Compliance Calendar
| Return / Filing | Frequency | Filed With |
|---|---|---|
| Quarterly Progress Report | Quarterly | Development Commissioner |
| Annual Performance Report (APR) | Annual | Development Commissioner / UAC |
| Softex (services exports) | Monthly | Authorised Dealer bank / STPI |
| GST returns (GSTR-1, 3B) | Monthly / Quarterly | GSTN |
Common Pitfalls
- Assuming a fresh Section 10AA holiday for a unit commencing after 31 March 2020 — it is not available.
- Missing the cumulative NFE test because DTA sales were treated as exports.
- Not executing or renewing the BLUT, which stalls duty-free procurement.
- Confusing an SEZ (SEZ Act) with an EOU (FTP scheme) — they are separate regimes.
