Supplies to SEZ under GST – Role of LOA, Approved List, DPF/DSPF, Endorsements and Tax Implications

One of the most misunderstood areas under GST is the treatment of supplies made to SEZ units or SEZ developers. Many businesses assume that every supply to an SEZ automatically becomes zero-rated. However, in practice, GST authorities verify whether the supply is specifically approved for “authorized operations” of the SEZ unit.

This is where documents such as:

• Letter of Approval (LOA),
• Approved list of goods/services,
• DTA Procurement Form (DPF),
• DTA Service Procurement Form (DSPF), and
• Endorsement from Specified Officer become critically important.

A supplier must understand not only the GST provisions but also the SEZ procedural framework to avoid tax disputes and refund rejections.

---

1. Meaning of LOA (Letter of Approval)

The Letter of Approval (LOA) is an approval issued by the Development Commissioner of the SEZ to an SEZ unit or SEZ developer under the SEZ Act, 2005.

The LOA authorizes:

• establishment of the SEZ unit,
• nature of business activities,
• approved operations,
• permitted procurement and imports.

In simple terms:

LOA is the foundational approval proving that the entity is a legally approved SEZ unit/developer.

However, merely having an LOA is not always sufficient for GST zero-rating benefits.

---

2. Is LOA Alone Sufficient?

Practical Position – NO

In GST assessments and refund proceedings, officers generally insist on:

1. LOA,
2. Approved list/Annexure of goods and services,
3. SEZ online approval forms,
4. Endorsement from specified officer.

The reason is simple:

• LOA confirms SEZ status,
• Annexures confirm whether the particular goods/services are approved for authorized operations.

Therefore:

LOA establishes existence of SEZ unit, but annexures establish eligibility of specific procurement.

---

3. What is the “Approved List” or Annexure?

After issuance of LOA, the SEZ authorities approve:

• list of goods,
• list of services,
• capital goods,
• consumables,
• input services required for authorized operations.

These approvals are generally issued as annexures or approved procurement lists.

---

4. Why is Approved List Important?

GST zero-rating is available only if:

• goods/services are used for authorized operations.

Therefore, during audits or refund verification:

• authorities compare the supplier invoice
  with
• approved annexure list.

If the supplied item is not appearing in the approved list, authorities may deny zero-rated treatment.

---

5. DTA Procurement Forms – DPF (Data Procurement Form) and DSPF (Data Service Procurement Form)

Supplies from Domestic Tariff Area (DTA) to SEZ are generally processed through SEZ online systems.

---

A. DPF – DTA Procurement Form

Used for:

• procurement of goods from DTA into SEZ.

Purpose:

• approval and tracking of inward movement of goods into SEZ.

The form typically contains:

• supplier details,
• GSTIN,
• invoice details,
• description of goods,
• quantity/value,
• purpose/use,
• approval references.

---

B. DSPF – DTA Service Procurement Form

Used for:

• procurement of services by SEZ units from DTA suppliers.

Purpose:

• approval of services for authorized operations.

Contains:

• service description,
• vendor details,
• service period,
• value,
• approval references.

---

6. SEZ Online Portal Processing

Most SEZs now process procurements through SEZ online systems.

Typical process:

Step	Activity
1	SEZ unit raises DPF/DSPF
2	Internal approval by SEZ unit
3	Submission to Specified Officer
4	Approval/endorsement
5	Supplier supplies goods/services
6	Endorsed invoice generated

---

7. What is Endorsement from Specified Officer?

The “Specified Officer” is an officer authorized under SEZ law to supervise SEZ operations.

The endorsement confirms:

• goods/services were actually received in SEZ,
• supplies are for authorized operations.

This endorsement is one of the most important documents under GST.

---

8. Why is Specified Officer Endorsement Critical?

Under GST refund procedures, endorsement acts as evidence that:

• zero-rated supply conditions are fulfilled.

Without endorsement:

• refund claims may be rejected,
• zero-rating benefit may be disputed.

---

9. Documents to be Verified Before Supply

A. Mandatory Basic Documents

Document	Purpose
GST Registration	Verify SEZ status
LOA	Confirm SEZ approval
Approved Annexure List	Verify authorized goods/services
DPF/DSPF	Procurement authorization
Purchase Order	Commercial documentation
LUT copy	If supply without IGST

---

B. Additional Important Documents

Document	Importance
SEZ online approval screenshot	Audit support
Authorization letter	Authorized signatory verification
Service agreement	For service supplies
Delivery instructions	Movement evidence

---

10. Pre-Supply Verification – Practical Checklist

Before issuing invoice, supplier should verify:

Goods Supply

• Whether goods appear in approved annexure.
• Whether DPF is approved.
• Whether SEZ GSTIN is valid.
• Whether place of delivery is SEZ premises.
• Whether LUT is valid (if no IGST charged).

---

Service Supply

• Whether service appears in approved service list.
• Whether DSPF is approved.
• Whether service relates to authorized operations.
• Whether service location and agreement support SEZ usage.

---

11. What if Goods/Services Are NOT in Approved Annexure?

This is one of the most critical practical issues.

Goods Not Approved for Authorized Operations

If supplied goods/services are NOT covered in:

• approved annexure,
• DPF/DSPF,
• authorized operations approval,

then supply may lose zero-rated benefit.

In such cases:

• supplier should generally treat supply as normal taxable supply.

---

12. Which Tax Should Be Charged – IGST or CGST/SGST?

The answer depends on place of supply provisions.

---

A. Supply to SEZ Is Always Inter-State Supply

As per Section 7(5)(b) of IGST Act:

Supply to or by SEZ is treated as inter-state supply.

Therefore:

Even if zero-rating benefit is denied,
the transaction generally remains:

• an inter-state supply.

Hence:

• IGST should be charged.

---

B. Practical Interpretation

Scenario	Tax Treatment
Approved for authorized operations	Zero-rated (with LUT or IGST refund route)
Not approved for authorized operations	IGST applicable as normal taxable inter-state supply

Thus:

If goods are not covered in annexure/authorized operations, supplier should generally raise invoice with IGST, not CGST+SGST.

---

13. Can CGST & SGST Ever Apply?

Normally, no.

Because supplies to SEZ are specifically deemed inter-state supplies under IGST Act irrespective of location.

Therefore:

• CGST + SGST usually should not be charged on SEZ supplies.

---

14. Reporting in GSTR-1 and GSTR-3B

One of the most important compliance aspects is proper GST return reporting.

Incorrect reporting frequently results in:

• refund rejection,
• GST notices,
• mismatch proceedings,
• denial of zero-rated benefit.

---

A. Where to Report Eligible Zero-Rated SEZ Supplies

In GSTR-1

Table 6B – Supplies Made to SEZ Unit/Developer

Report supplies here when:

• goods/services are for authorized operations,
• approved annexure exists,
• DPF/DSPF approval available,
• endorsement from specified officer available.

Applicable for:

• supply under LUT without payment of IGST,
• supply with payment of IGST.

---

In GSTR-3B

Table 3.1(b) – Outward Taxable Supplies (Zero Rated)

This table covers:

• exports,
• SEZ zero-rated supplies.

---

B. Where to Report Supplies NOT Approved for Authorized Operations

If:

• supplied goods/services are not included in approved annexure,
• DPF/DSPF approval absent,
• endorsement unavailable,
• supply not linked to authorized operations,

then:

zero-rated benefit may not be available.

In such cases, although recipient is an SEZ unit, the supply should generally be treated as a normal taxable inter-state supply.

---

Reporting in GSTR-1

Table 4 – Taxable B2B Supplies

Reason:

• transaction loses zero-rated status,
• but remains taxable inter-state B2B supply.

---

Reporting in GSTR-3B

Table 3.1(a) – Outward Taxable Supplies (Other than zero rated, nil rated and exempted)

Reason:

• normal taxable outward supply,
• IGST payable.

---

15. Practical Reporting Summary

Situation	GSTR-1	GSTR-3B	Tax Treatment
Authorized operations approved	Table 6B	Table 3.1(b)	Zero-rated
Not approved/not endorsed	Table 4 (B2B)	Table 3.1(a)	Normal IGST supply

---

16. Post-Supply Documents to be Maintained

A. For Goods

Document	Purpose
Tax invoice	Primary GST document
E-way bill	Movement proof
LR/Transport proof	Delivery evidence
Endorsed invoice	SEZ receipt proof
Gate entry acknowledgment	Physical entry evidence
Approved DPF	Authorized procurement proof

---

B. For Services

Document	Purpose
Invoice	GST compliance
DSPF approval	Service authorization
Agreement/work order	Nature of service
Service completion report	Delivery proof
Endorsed invoice	SEZ officer confirmation

---

17. Refund Risk Areas

GST officers commonly scrutinize:

• mismatch between invoice and annexure,
• missing endorsement,
• expired LOA,
• invalid LUT,
• absence of DPF/DSPF,
• services not linked to authorized operations,
• incorrect reporting in GSTR-1 and GSTR-3B.

---

18. Important Practical Recommendation for Suppliers

Suppliers should never rely solely on verbal confirmation from SEZ customers.

Always obtain:

• LOA,
• approved annexure,
• approved DPF/DSPF,
• specified officer endorsement.

This protects the supplier during:

• GST audit,
• refund proceedings,
• departmental investigations.

---

19. Suggested Internal SOP for SEZ Supplies

Pre-Supply SOP

Verify:

✔ GSTIN
✔ LOA validity
✔ Annexure approval
✔ DPF/DSPF approval
✔ LUT validity
✔ PO and agreement

---

Post-Supply SOP

Collect:

✔ Endorsed invoices
✔ Delivery proof
✔ E-way bill
✔ Transport documents
✔ Service reports
✔ Refund reconciliation

---

Conclusion

Supplies to SEZ are legally inter-state supplies and therefore attract IGST under GST law. However, when supplies are made for authorized operations and proper documentation is maintained, the transaction qualifies as a zero-rated supply.

The most important practical takeaway is:

LOA alone is not sufficient.

Suppliers should additionally verify:

• approved annexures,
• DPF/DSPF approvals,
• specified officer endorsements.

If the supplied goods or services are not included in the approved authorized operations list, zero-rated benefit may not be available. In such cases:

• supplier should generally charge IGST,
• report the transaction in GSTR-1 Table 4,
• report it in GSTR-3B Table 3.1(a) as a normal taxable supply.

Only supplies genuinely qualifying for authorized operations and supported by proper documentation should be reported as:

• GSTR-1 Table 6B, and
• GSTR-3B Table 3.1(b).

In SEZ transactions, documentation is the foundation of GST compliance. Proper verification before supply and proper endorsement after supply are essential to safeguard zero-rating benefits and avoid future litigation.

Official GSTN Advisory · May 2026 Enhancements in the e-Way Bill Portal

Enhancements in the
e-Way Bill Portal

A comprehensive guide to the mandatory Ship-To GSTIN requirement and the new voluntary EWB Closure facility — what you need to know before June 15, 2026.

Advisory No. 661Issued By GSTNDate 20 May 2026Production Cutover 15 Jun 2026

⚠ Action Required Before June 15, 2026

GSTN has announced two significant functional changes to the e-Way Bill (EWB) portal — mandatory Ship-To GSTIN capture and a new voluntary EWB Closure facility. Production deployment is scheduled for 15 June 2026. All taxpayers, transporters, ERP vendors, GSPs, and ASPs must prepare their systems now.

Why Is GSTN Upgrading the EWB System?

The Goods and Services Tax Network (GSTN), in its Advisory No. 661 dated 20 May 2026, has announced key functional enhancements to the e-Way Bill portal. These changes are driven by a clear mandate: strengthen data integrity across the supply chain, improve traceability of goods movement, and enable systematic closure of completed transactions.

Since the launch of the e-Way Bill system, a persistent challenge has been the lack of accurate destination data — particularly in Bill-To/Ship-To scenarios where goods are invoiced to one party but physically delivered to another. This gap created discrepancies in GSTIN-level tracking, audit trails, and tax enforcement. Simultaneously, there was no formal mechanism for taxpayers to signal the completion of a delivery against a generated EWB, leaving a large number of "ghost" EWBs floating in the system even after goods were delivered.

The two enhancements announced by GSTN directly address these pain points.

📍

Mandatory Ship-To GSTIN

The "Ship To GSTIN" field in Bill-To/Ship-To transactions will now be a required data element during EWB generation — closing a critical data gap.

✅

Voluntary EWB Closure

A brand new facility enabling suppliers, recipients, transporters, and drivers to voluntarily close an EWB once delivery of goods is completed.

Mandatory Capture of "Ship-To GSTIN" in Bill-To/Ship-To Transactions

This is the more immediately impactful change for businesses involved in multi-party supply chains — particularly manufacturers, distributors, and e-commerce operators who regularly handle Bill-To/Ship-To transactions.

What Is a Bill-To/Ship-To Transaction?

A Bill-To/Ship-To scenario arises when the party to whom a tax invoice is raised (the Bill-To party) is different from the party to whom the goods are physically delivered (the Ship-To party). This is extremely common in:

• Dealer/distributor arrangements where an OEM invoices the dealer but goods go directly to the sub-dealer or end customer.
• Drop shipments arranged through e-commerce marketplaces.
• Procurement-on-behalf arrangements in large corporate groups.
• Export-oriented units where billing and physical delivery locations differ.

What Has Changed?

Under the revised EWB generation framework, the "Ship To GSTIN" field will be treated as a mandatory data element in all Bill-To/Ship-To transactions. Previously, this field was either absent or optional, leading to a situation where the actual recipient's GSTIN was not captured in the system.

In cases involving Bill-To/Ship-To scenarios, the field relating to the "Ship To GSTIN" shall now be captured as a mandatory data element during e-Way Bill generation.

— GSTN Advisory No. 661, dated 20 May 2026

Special Rule for Unregistered Consignees

Where the party receiving the goods does not hold a GST registration (i.e., an unregistered person or consumer), taxpayers must enter the value "URP" (Unregistered Person) in the "Ship To GSTIN" field. This ensures the field is never left blank while distinguishing unregistered recipients from registered ones.

Ship To GSTIN field rules:

→ Registered consignee : Enter consignee's valid GSTIN
→ Unregistered consignee: Enter "URP"
→ Field left blank : ❌ EWB generation will FAIL

Why Does This Matter?

This change directly tightens the loop between e-Way Bill data and GSTR-1/GSTR-3B returns. By mandating Ship-To GSTIN, GSTN can now systematically cross-verify whether the declared recipient in the EWB matches the Input Tax Credit (ITC) claimed by that GSTIN in their returns. It also helps tax authorities track the physical movement of goods more accurately, making it harder for fraudulent transactions to go unnoticed.

Scenario	Bill-To GSTIN	Ship-To GSTIN	Status
Goods billed and delivered to same party	Party's GSTIN	Same as Bill-To	Standard
Goods billed to A, delivered to B (registered)	A's GSTIN	B's GSTIN (mandatory)	New Rule
Goods delivered to unregistered consumer	Supplier's GSTIN	"URP"	New Rule
Drop-ship to dealer's customer	Dealer's GSTIN	Customer's GSTIN or URP	New Rule

Introduction of the Voluntary e-Way Bill Closure Facility

The second major enhancement is entirely new in concept — the introduction of a formal EWB Closure mechanism. Until now, there was no structured way in the EWB system for a taxpayer or transporter to signal that goods had been delivered and the EWB's purpose was fulfilled. This led to a proliferation of "open" EWBs in the system long after the underlying transactions were completed.

Who Can Close an EWB?

The closure facility has been made available to multiple parties involved in the supply chain:

1. 1. Supplier — The party who generated the EWB and dispatched the goods.
   
   2. Recipient — The party to whom the goods were delivered (the Bill-To party).
   
   

2. 3. Transporter — The logistics provider involved in the movement of goods.
3. 
   
4. 4. Driver / Authorised Person — A driver or other authorised individual whose mobile number has been linked to the EWB at the time of generation for closure purposes.

How Can EWBs Be Closed? Three Methods Available

Method A — Portal Login (Logged-in Users)

For suppliers, recipients, and transporters, the EWB Closure option is available directly after logging in to the e-Way Bill Common Portal under the e-Way Bill section. Closure can be performed in two modes:

• EWB-wise closure:
  Search and close a specific e-Way Bill by its number.
• Date-wise closure:
  Close all EWBs generated on or before a specified date, useful for batch reconciliation at the end of the day.

Method B — Mobile Number-Based Closure (Drivers / Authorised Persons)

A mobile number may be entered at the time of EWB generation specifically for closure purposes. This is currently voluntary and can be updated during vehicle updation, consolidated EWB operations, or validity extension processes.

The mobile number-based closure facility has been placed under the Search option on the EWB Common Portal. All active EWBs linked to the concerned mobile number are displayed, enabling the authorised person (e.g., a delivery driver) to close them directly without needing to log in with a GSTN username.

Method C — API-Based Closure (System Integrators)

For businesses using ERP systems or API integrations, a dedicated API has been provided. 

Important Time Rule for Closure

EWBs can only be closed:

• On thesame day of delivery, or
• On theimmediately succeeding day(i.e., the day after delivery).

This time restriction ensures that the closure is tied as closely as possible to the actual delivery event, preserving the integrity of the system.

💡 Key Insight

The EWB Closure facility is currently voluntary. However, GSTN's broader objective of enabling "system-driven closure of transactions" strongly suggests that mandatory EWB closure may be introduced in future phases. Early adoption now will prepare your business for that eventuality.

API & System Integration — What You Need to Do

The National Informatics Centre (NIC) has already released the updated API specifications in the Sandbox environment. Production deployment is confirmed for 15 June 2026. This gives ERP vendors, GSPs, ASPs, and system integrators approximately three weeks to test and certify their integrations.

Frequently Asked Questions

1. Is the EWB Closure facility mandatory from 15 June 2026?

No. As per the advisory, the EWB Closure facility is being introduced on a voluntary basis. However, GSTN's stated objective of "enabling system-driven closure of transactions" suggests this may become mandatory in a future phase. Businesses are encouraged to adopt it now to build compliance readiness.

2. What happens if I forget to close an EWB on the delivery day?

EWBs can be closed on the same day of delivery or on the immediately succeeding day. If neither window is used, the EWB will remain in "open" status in the system. While there is no immediate penalty (given the facility is currently voluntary), unresolved open EWBs may create reconciliation challenges in future audits or when GSTN introduces mandatory closure.

3. What if the Ship-To party is a consumer with no GST registration?

In such cases, enter "URP" (Unregistered Person) in the Ship-To GSTIN field. This is the prescribed approach for all unregistered consignees and must not be left blank.

4. Can the closure mobile number be changed after EWB generation?

Yes. The mobile number linked for closure purposes can be updated during vehicle updation, consolidated EWB operations, or validity extension. This provides flexibility for situations where a different driver takes over a delivery mid-route.

5. Where can ERP vendors access the updated API specifications?

The updated API specifications are available in the Sandbox environment of the EWB Common Portal managed by NIC. Vendors are advised to access these immediately and complete testing well before the 15 June 2026 production cutover. For implementation queries, GSTN's designated helpdesk channels should be contacted.

6. Does the Ship-To GSTIN need to match GSTR-1 data?

Yes, the intent of the Ship-To GSTIN requirement is precisely to enable cross-verification between EWB data and GST returns (GSTR-1 and GSTR-3B). Businesses should ensure that the GSTIN entered as Ship-To GSTIN is the party actually claiming ITC on those goods, as mismatches will likely trigger notices or flags in the GSTN reconciliation system.

What This Means for the GST Ecosystem

GSTN's Advisory No. 661 represents a meaningful step forward in the maturation of India's e-Way Bill infrastructure. The mandatory Ship-To GSTIN requirement closes one of the most significant data gaps in the current system — the inability to track who actually receives goods as distinct from who is billed for them. Combined with the voluntary EWB Closure facility, the overall health of transaction data on the portal is set to improve substantially.

For businesses, the immediate priority is ensuring that ERP systems are updated, master data for Ship-To GSTINs is in order, and teams are trained on the new workflows before 15 June 2026. For transporters and logistics companies, activating the mobile number-based closure mechanism for drivers represents a simple yet effective way to bring supply chain closure data into the GST system in real time.

Tax professionals and GST consultants should proactively reach out to their clients — particularly those in multi-party supply chain arrangements — to assess the impact and ensure seamless compliance from day one of production rollout.

The enhancements are being implemented to strengthen data integrity, improve traceability of goods movement, and enable system-driven closure of transactions.
