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

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.

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.
