INTEGRATED GOODS AND SERVICES TAX ACT, 2017
Chapter VII — ZERO RATED SUPPLY (Section 16)
Chapter Index — fourteen-section practitioner architecture
Effective from 1 July 2017 (IGST Act, 2017) | First Edition | May 2026
[Single-section chapter — the operational centrepiece of India's export-promotion architecture under GST; definition + ITC preservation + LUT vs IGST-paid refund routes + FA 2021 amendments]
1. Scope at a Glance
Chapter VII of the IGST Act has a single section — s. 16 — which is the operational centrepiece of India's export-promotion architecture. Sub-section (1) defines zero-rated supply as (a) export of goods/services or (b) supply to SEZ developer/unit (restricted to 'authorised operations' post FA 2021 amendment when notified). Sub-section (2) preserves ITC despite zero-rated character — the critical override of standard s. 17(2) CGST blocking. Sub-section (3) provides the refund mechanism (LUT route as default post FA 2021, with non-realisation deposit proviso). Sub-section (4) (inserted by FA 2021) gives Government power to notify classes eligible for IGST-paid route. Pre FA 2021 notification, both LUT and IGST-paid routes remain available to all exporters.
