Union Budget 2026 – Customs & Trade Facilitation Overhaul: Practical Guide to Key Changes

Union Budget 2026 puts strong emphasis on Customs reforms – combining tariff restructuring, exemption pruning, export promotion, logistics facilitation and process digitisation. While GST/IGST changes are relevant, this write-up focuses entirely on Customs and trade facilitation proposals, explaining the “before vs after” scenario and practical impact for businesses, importers, exporters and intermediaries.

Most provisions relating to customs processes and tariff changes are designed to reduce friction, accelerate clearances and support Make in India and export-oriented manufacturing. However, several exemptions have been withdrawn or rationalised, and a few duty increases have been proposed, which require close attention to ensure that landed cost computations and pricing models are updated in time.

Below is a structured, topic-wise analysis of the Customs-related announcements in the Union Budget 2026.

A1. Policy Direction: Exemption Review & Tariff Simplification

Strategic Objectives in Budget Speech (Para 1–3)

The Budget speech lays down three broad policy pillars for Customs:

  • Tariff rationalisation and simplification
  • Selective roll-back of long-standing exemptions
  • Improved trade facilitation and ease of doing business

Exemption Review – Moving Away from Legacy Reliefs

Historically, numerous customs exemptions have continued for goods that are now either manufactured locally in sufficient quantity or see marginal import volumes. The Budget proposes to:

  • Identify such legacy exemptions; and
  • Withdraw them for specified products where:
    • Domestic manufacturing is adequately developed; or
    • Imports are negligible and the exemption no longer serves an economic purpose.

This leads to a more neutral duty framework and reduces classification and notification disputes.

Tariff Simplification – Shifting Effective Rates into the Tariff Schedule

Multiple items currently enjoy effective duty rates by way of exemption notifications, creating a gap between the statutory rate in the Customs Tariff and the actual rate paid.

The Budget moves to:

  • Incorporate these effective rates directly into the First Schedule of the Customs Tariff Act, 1975; and
  • Reliance on parallel exemption notifications is correspondingly reduced.

Note: This change will make it easier to identify the applicable rate from the tariff itself, improving transparency and reducing errors in BoE filings.

A2. Export Promotion – Sectoral Incentives & Extended Time Limits

Duty-Free Inputs for Seafood Exports (Para 4 / Annexure D.1)

For enterprises engaged in seafood exports, the duty-free import limit for specified inputs is being substantially expanded.

  • Earlier: Limit pegged at 1% of prior year FOB export turnover
  • Now: Limit increased to 3% of prior year FOB export turnover

This higher ceiling allows exporters to import more inputs without customs duty, supporting competitiveness and value-added seafood exports.

Inclusion of Shoe Uppers in Duty-Free Export Scheme (Para 5 / Annexure D.3)

Exports of shoe uppers are now explicitly brought within the ambit of duty-free input schemes.

  • Earlier: Exports of shoe uppers did not enjoy the notified duty-free input benefit
  • Now: Shoe uppers are covered, enabling import of specified inputs at concessional / nil duty for export production

This measure deepens support to the leather and footwear value chain.

Extended Period for Export of Final Product (Para 6 / Annexure D.2)

To provide operational flexibility, the time limit for effecting export of final products has been extended:

  • Earlier: Standard export period – 6 months
  • Now: Export period enhanced to 12 months / 1 year

This helps exporters manage production and logistics disruptions, especially for complex products and seasonal demand.

A3. Sector-Specific Customs Duty Reliefs

Li-ion Cells for Battery Energy Storage Systems (BESS) (Para 7)

Existing exemptions on capital goods used for manufacturing Li-ion cells (batteries) are now extended specifically to Li-ion cells for BESS.

  • Earlier: Exemption limited to Li-ion cells used in batteries
  • Now: Exemption also covers Li-ion cells for Battery Energy Storage Systems (BESS)

This aligns with the push towards grid-scale energy storage and renewable integration.

Input for Solar Glass – Sodium Antimonate (Para 8)

Customs duty on sodium antimonate, a critical input for solar glass, is being fully exempted.

  • Earlier: Basic Customs Duty (BCD) was chargeable
  • Now: BCD is exempt, lowering cost of solar glass manufacturing

This reduces project costs across the solar value chain.

Nuclear Power Projects – Extended Exemption Horizon (Para 9)

The Budget continues and enlarges the customs duty benefit for nuclear power project imports:

  • Earlier: Exemption existed but was limited in scope and timeline
  • Now:
    • Exemption is extended up to 2035; and
    • Coverage is widened to all nuclear plants irrespective of capacity

This grants long-term visibility for nuclear project developers and import planners.

Capital Goods for Processing Critical Minerals (Para 10)

To support domestic processing of strategic/critical minerals, BCD on capital goods required for such processing is fully relieved.

  • Earlier: BCD was applicable on capital goods for mineral processing
  • Now: BCD exempt, incentivising investments in critical mineral value chains.

Civil Aviation – Aircraft Manufacturing Components (Para 12)

BCD is being exempted on components and parts used for manufacture of aircraft.

  • Earlier: BCD payable on such imported parts
  • Now: BCD exempt, improving viability of domestic aircraft manufacturing.

Defence Aviation – MRO Raw Materials (Para 13)

For defence sector MRO, BCD on raw materials used in manufacture of aircraft parts for MRO by defence units is withdrawn.

  • Earlier: BCD levied on such raw materials
  • Now: BCD exempt, strengthening the domestic defence maintenance, repair and overhaul ecosystem.

Electronics – Microwave Oven Components (Para 14)

To encourage deeper value addition in the appliance sector, certain parts for microwave ovens are granted BCD exemption.

  • Earlier: BCD payable on specified microwave oven parts
  • Now: BCD exempt on notified inputs, aiding domestic assembly and manufacturing.

SEZ Units – One-Time Facilitated DTA Sale (Para 15)

Eligible SEZ units are to be allowed one-time sale to DTA at concessional duty, subject to a cap linked to export performance.

  • Earlier: Regular SEZ to DTA rules applied, with no such one-time concession
  • Now: A limited concessional duty window is introduced, tied to the unit’s export proportion

This measure is designed to unlock idle capacities while retaining safeguards against misuse.
