SEZ Units — Law of Taxation Notes

SEZ Units

Inside India, yet treated as outside it for customs — a Special Economic Zone is a duty-free enclave where an exporter can import inputs and machinery without paying customs duty, so long as he produces for export. It is a deliberate carve-out to make Indian exports globally competitive.

The SEZ concept

A Special Economic Zone (SEZ) is a specially delineated duty-free enclave governed by the Special Economic Zones Act, 2005, deemed to be foreign territory for the purposes of trade operations, duties and tariffs. A unit set up in an SEZ (“SEZ unit”) enjoys:

• Duty-free import (and domestic procurement) of goods — capital goods, raw materials, consumables — for its authorised operations, without customs duty;
• Exemption/benefits on exports and specified taxes, subject to conditions;
• A single-window clearance and a simplified regulatory regime;
• An obligation to be a net foreign-exchange earner (broadly, to export more than it imports over a period).

Customs treatment. Because the SEZ is deemed outside the customs territory of India:

• Goods going from the Domestic Tariff Area (DTA) into an SEZ are treated as exports (zero-rated under GST — Unit III);
• Goods coming from an SEZ into the DTA are treated as imports and attract customs duty as if freshly imported.

Under GST, supplies to an SEZ unit/developer are zero-rated (s.16 IGST), so the SEZ dovetails with the export-promotion policy.

🧩 WORKED EXAMPLE — Movement to and from an SEZ

Facts. (a) A DTA supplier sells inputs to an SEZ unit; (b) the SEZ unit later sells finished goods into the DTA.

Rule. An SEZ is deemed foreign territory: DTA-to-SEZ = export (zero-rated); SEZ-to-DTA = import (customs duty applies).

Apply. (a) The DTA supplier’s supply to the SEZ is a zero-rated export — no GST, ITC preserved. (b) The SEZ unit’s clearance into the DTA is treated as an import, so the DTA buyer pays customs duty (and IGST) as on any import.

Conclusion. Selling into an SEZ is duty-free (export); bringing goods out of an SEZ into India attracts import duty — the enclave is inside India geographically but outside it for customs.

In Simple Terms: An SEZ (SEZ Act, 2005) is a duty-free zone treated as foreign territory for customs. An SEZ unit can import inputs and machinery duty-free for export production. Selling into an SEZ counts as an export (zero-rated); bringing goods out into the rest of India counts as an import and attracts customs duty.

Case Laws

• Commissioner of Customs v Dilip Kumar & Co. (2018) — exemptions and duty-free benefits (including enclave schemes) are strictly construed; the claimant must meet every condition.
