Advance Authorisation vs DFIA: Which Duty Exemption Scheme Should You Use?

What Is Advance Authorisation?

Advance Authorisation (AA) is a duty exemption scheme under Chapter 4 of the Foreign Trade Policy that allows exporters to import inputs (raw materials, components, consumables, packing materials, and fuel) without paying customs duty. The condition is straightforward: the imported inputs must be used in the manufacture of the export product.

The quantities of inputs you can import duty-free are governed by norms. If your product has a Standard Input-Output Norm (SION) published by DGFT, those norms apply automatically. If no SION exists for your product, you can apply for ad-hoc norms. DGFT's Norms Committee will fix input-output ratios specific to your manufacturing process.

AA is product-specific and input-specific. The authorisation ties a particular export product to particular imported inputs. You cannot divert the imported inputs to a different product or sell them in the domestic market. This "actual user" condition stays in force throughout the life of the authorisation.

Key Features of Advance Authorisation

• Duty-free imports. Exemption from Basic Customs Duty, IGST, and Compensation Cess on imported inputs.
• SION or ad-hoc norms. Input quantities are fixed by published norms or determined case by case.
• Export obligation period. 18 months from the date of authorisation.
• Pre-export or post-export. You can import inputs before exporting the finished product, or export first and import inputs later.
• Non-transferable. The authorisation and the imported inputs cannot be sold or transferred to another party.

What Is DFIA?

Duty Free Import Authorisation (DFIA) is another duty exemption scheme under Chapter 4 of the Foreign Trade Policy. On the surface it looks similar to Advance Authorisation. It lets you import inputs duty-free for export production. But DFIA has one critical difference: the authorisation becomes transferable after the export obligation is met.

DFIA is issued only for products that have published SION norms. You cannot get a DFIA for products that require ad-hoc norms. This makes the scheme narrower in scope than Advance Authorisation but simpler to administer. The input-output ratios are already published, so there is no waiting for a Norms Committee decision.

The transferability feature is what makes DFIA attractive. Once you complete the export and obtain your Export Obligation Discharge Certificate (EODC), the DFIA scrip can be sold in the open market. Any importer (not just exporters) can buy your DFIA and use it to import goods duty-free. These scrips typically trade at 3-5% of the duty value saved, giving you a direct revenue stream even if you do not need the duty-free imports yourself.

Key Features of DFIA

• Transferable after EODC. The scrip can be sold to any importer once the export obligation is discharged.
• SION norms only. Available only for products with published Standard Input-Output Norms.
• Export obligation period. 12 months from the date of authorisation.
• Post-export only. DFIA is issued after exports are made (you cannot import before exporting under DFIA).
• Market value. Transferable scrips trade at approximately 3-5% of the duty value saved.

Head-to-Head Comparison: AA vs DFIA

The table below compares Advance Authorisation and DFIA across 10 key parameters that matter for your duty exemption decision.

Advantages of Advance Authorisation

Advance Authorisation is the more flexible of the two schemes, primarily because it is not restricted to SION-listed products.

• Available for any product. If no SION exists, you can apply for ad-hoc norms. This makes AA the only option for custom-manufactured, niche, or new-to-market products.
• Pre-export imports allowed. You can import duty-free inputs before making the export. This is critical for manufacturers who need to procure raw materials before production begins.
• Lower value addition threshold. AA requires 15% minimum value addition compared to 20% for DFIA. For products with thin processing margins (like certain chemicals or intermediates), this lower threshold can be the deciding factor.
• Flexibility in input sourcing. AA allows you to specify your actual inputs, and with ad-hoc norms, the quantities are tailored to your real manufacturing process rather than standardised averages.
• Can be combined with [EPCG](/resources/epcg-scheme). An exporter can hold both an Advance Authorisation (for duty-free inputs) and an EPCG licence (for duty-free capital goods) simultaneously, maximising duty savings.

Advantages of DFIA

DFIA's transferability feature creates opportunities that Advance Authorisation simply cannot match.

• Transferable scrips have market value. DFIA scrips typically trade at 3-5% of the duty value saved. On a large export order with significant duty entitlement, this can amount to a meaningful addition to your margins.
• Monetise even without imports. If you source all your inputs domestically and do not need duty-free imports, you can still apply for DFIA and sell the scrip. With AA, the authorisation is worthless if you do not import.
• Simpler norms. Because DFIA uses only published SION norms, there is no waiting for Norms Committee decisions or ad-hoc approvals. The input-output ratios are known upfront.
• Useful for merchant exporters. Merchant exporters who buy finished goods from manufacturers and export them can benefit from DFIA's transferability, selling the scrip rather than using it for imports.
• Faster EODC. The EODC process for DFIA is typically faster because SION norms are standardised and verification is more straightforward.

When to Choose Advance Authorisation

Advance Authorisation is the better choice when you genuinely need duty-free imported inputs for your manufacturing process. Here are the specific scenarios where AA wins:

• You actually import inputs for manufacturing. If your production depends on imported raw materials, components, or consumables, AA directly reduces your input cost.
• Your product does not have SION norms. DFIA is not available for products without SION. AA with ad-hoc norms is your only duty exemption option.
• You need to import before exporting. If your production cycle requires procuring inputs first, AA's pre-export import facility is essential. DFIA only works post-export.
• Your value addition is between 15-20%. If your manufacturing process adds less than 20% value but more than 15%, you qualify for AA but not DFIA.
• You want flexibility in input specifications. Ad-hoc norms under AA can be tailored to your actual manufacturing process, allowing more accurate input-output ratios than standardised SION norms.

A good example is a chemical manufacturer exporting a speciality compound that does not appear in the SION list. The manufacturer imports three specific reagents from Germany and Japan. Advance Authorisation with ad-hoc norms lets the manufacturer fix input quantities based on actual batch consumption, import those reagents duty-free, and export the finished compound. All within the authorisation period. DFIA would not be an option here because the product lacks SION norms.

When to Choose DFIA

DFIA is the smarter choice when you want to monetise your duty entitlement rather than use it for imports, or when you want the option to do either.

• Your product has SION norms. This is the basic eligibility requirement. Check the DGFT portal for published SION norms for your export product.
• You source inputs domestically. If you buy raw materials from Indian suppliers and do not need duty-free imports, DFIA lets you sell the transferable scrip for 3-5% of duty value.
• You want optionality. With DFIA, you can either use the scrip to import duty-free (before EODC) or sell it in the market (after EODC). AA locks you into the import-and-use path.
• You export regularly in SION categories. For repeat exporters with predictable volumes in SION-listed products, DFIA becomes a consistent revenue stream on top of export proceeds.
• You are a merchant exporter. Merchant exporters who procure finished goods domestically for export can earn DFIA scrips and sell them, adding margin without any import requirement.

Consider a textile exporter who buys fabric from domestic mills and exports garments to Europe. The exporter does not import any raw materials. Under Advance Authorisation, there would be no benefit. The AA scrip is non-transferable and useless without imports. Under DFIA, the exporter applies post-export, gets the EODC, and sells the scrip to an importer of polyester yarn who needs duty-free imports. The textile exporter earns 3-5% of the duty saved. Pure additional margin. Read more about related incentives in our Duty Drawback guide.

The GST Angle: Where Both Schemes Get Complicated

Both Advance Authorisation and DFIA exempt imports from IGST at the customs border. This is a significant benefit. IGST on imports is calculated on the assessable value plus Basic Customs Duty, so the exemption covers a substantial amount.

However, the GST treatment of domestic purchases under these schemes creates a practical challenge. When you buy inputs from domestic suppliers under an Advance Authorisation, the supplier charges you GST (CGST + SGST or IGST for interstate purchases). Since your final export is zero-rated, you accumulate Input Tax Credit (ITC) that you need to claim as a refund.

This creates two problems. First, the ITC refund process under GST is slow. Expect 2-6 months for processing. Second, there are frequent mismatches between your GSTR-2B (auto-populated from supplier returns) and your actual ITC claims, leading to queries and delays.

Some exporters choose to pay IGST on imports and claim it as ITC, rather than taking the IGST exemption under AA or DFIA. This simplifies the GST return filing process but requires more upfront capital. The decision depends on your cash flow position and how quickly your jurisdictional GST office processes refunds.

Frequently Asked Questions

Can I use both Advance Authorisation and DFIA for the same export product?

No. You must choose one duty exemption scheme per export consignment. You cannot claim Advance Authorisation and DFIA for the same shipment. However, different consignments of the same product can use different schemes. For example, you could use AA for one order where you need to import specific inputs, and DFIA for another order where you plan to source domestically and sell the scrip.

What happens if I fail to meet the export obligation under Advance Authorisation or DFIA?

If you fail to fulfil the export obligation within the prescribed period (18 months for AA, 12 months for DFIA), you must pay the exempted customs duty along with interest (currently 15% per annum) to the customs authorities. DGFT may also impose a penalty and restrict future authorisation issuance. You can apply for an extension of the export obligation period in genuine cases, but this requires documented justification and is not guaranteed.

Is DFIA transferable immediately after export?

No. A DFIA becomes transferable only after the export obligation is fully met and the Regional Authority of DGFT endorses the EODC (Export Obligation Discharge Certificate) on the licence. Until then, the DFIA is subject to an actual user condition, meaning only the licence holder can use it to import goods. Once the EODC is endorsed, the DFIA scrip can be freely sold to any importer in the market.
