CESTAT Mumbai- Customs Cannot Calculate Import IGST on Exempted BCD

The CESTAT Mumbai has held that where imports qualify for a Basic Customs Duty (BCD) exemption under a valid Duty-Free Import Authorisation (DFIA), IGST must be calculated without adding the notional tariff-rate BCD to the assessable value.
In TGI International v. Commissioner of Customs, Nhava Sheva-III, the Customs, Excise and Service Tax Appellate Tribunal (CESTAT), Mumbai set aside an order that had rejected the importerβs challenge to IGST assessments on 105 Bills of Entry. The Tribunal ruled that the relevant statutory test is the customs duty actually βchargeableβ after giving effect to a valid exemption notification, not the BCD shown in the tariff schedule.
Background: 105 DFIA-based fabric imports
TGI International, a fabric trader, imported polyester viscose fabrics through 105 Bills of Entry. It claimed full exemption from BCD under Notification No. 19/2015-Customs dated 1 April 2015, which applies to eligible imports made against a valid DFIA issued by the Directorate General of Foreign Trade (DGFT).
The DFIA scheme permits duty-free import of specified inputs subject to prescribed conditions, including production of the authorisation at clearance and endorsements relating to the export obligation and resultant product. In this matter, the Tribunal found that the importer had complied with the applicable DFIA and notification requirements.
Although the BCD claimed on the imports was nil, the Indian Customs EDI System (ICES) calculated IGST by adding BCD at the normal tariff rate of 20% to the transaction value. The importer paid the system-calculated IGST because the Bills of Entry could not be amended through the system, then appealed the assessments.
The core legal issue
The dispute concerned the meaning of βduty of customs chargeableβ when determining the value on which IGST is levied on imported goods.
Section 3(8) of the Customs Tariff Act, 1975 requires IGST to be calculated on an aggregate value comprising:
- the value of imported goods determined under Section 14 of the Customs Act, 1962; and
- any customs duty chargeable on the goods under Section 12 of the Customs Act.
TGI International argued that once the DFIA exemption reduced BCD to zero, there was no BCD amount to add to the assessable value for IGST. Customs authorities, however, treated the tariff-rate BCD as part of the IGST base, even though the importer did not pay that duty in cash.
Tribunalβs findings
Effective duty, not tariff duty, governs the IGST base
The Tribunal held that an exemption notification issued under Section 25 of the Customs Act must be given effect while determining the customs duty βchargeableβ under Section 12. Although the tariff rate of BCD on the goods was 20%, the effective BCD was nil because the imports were covered by the DFIA exemption.
Accordingly, the Tribunal concluded that the effective duty liability, rather than the unadjusted tariff rate, must be added to the import value when calculating IGST.
No duty debit was made under the DFIA
The Commissioner (Appeals) had reasoned that the customs duty was effectively discharged through debit in the DFIA authorisation. CESTAT rejected this conclusion as factually unsupported.
The Bills of Entry showed βzeroβ against the duty-debit field. The DFIA documentation recorded the permitted CIF value and quantity of dyed polyester fabrics, but did not require debit of the BCD amount as a precondition for the exemption. The Tribunal therefore found that it was incorrect to treat the tariff BCD as a duty discharged through the authorisation.
ICES could not override the legal valuation rule
The Tribunal noted that ICES had added a notional BCD amount while computing IGST and had not taken account of the exemption claimed under Notification No. 19/2015-Customs. System-generated assessments cannot displace the statutory requirement to use the duty actually chargeable after the applicable exemption is applied.
Reliance on earlier decisions
CESTAT found support in earlier Tribunal rulings that distinguish the tariff rate from the effective rate after exemptions:
- In Morarjee Brembana Ltd., the Tribunal held that only the effective customs duty, after applying the applicable exemption notification, should be added for calculating additional customs duty.
- In Parasrampuria International, the Tribunal held that where BCD is nil due to an exemption, no BCD amount can be added to the assessable value merely because a tariff rate otherwise exists.
The Revenue relied on Poddar Pigments Ltd., but CESTAT held that the case was distinguishable because it concerned interest on delayed IGST payment, not the correct BCD component for IGST valuation.
Why the ruling matters
The decision clarifies an important valuation principle for DFIA and other exemption-based imports: the IGST base must reflect the effective customs-duty liability, not a hypothetical duty calculated at the tariff rate.
For eligible DFIA imports, this means a nil BCD exemption should result in zero BCD being added to the IGST valuation base. The ruling also reinforces that customs assessment systems must apply the substantive benefit of a valid exemption notification rather than mechanically loading tariff-rate duty into the calculation.
Conclusion
By allowing TGI Internationalβs appeals, CESTAT Mumbai confirmed that a valid BCD exemption under the DFIA scheme must be fully reflected in IGST valuation. Where the effective BCD is nil, Customs cannot add the tariff-rate BCD notionally to inflate the IGST payable on imported goods.
