India Union Budget 2026-27 — Customs Notification 02/2026 zero-rates BCD on critical-minerals processing capital goods, BESS Li-ion cell machinery, and 12 critical minerals

Mechanism

The Budget 2026-27 customs package operates through three layered moves:

1. Notification-based BCD waivers (effective 2 Feb 2026) — Notification No. 02/2026-Customs zero-rates BCD on (a) the full equipment stack for critical-mineral processing (crushing, beneficiation, refining, chemical-processing reactors, separation / purification units, metallurgical and alloy-making machinery), and (b) capital goods for lithium-ion cell manufacturing dedicated to battery energy storage systems. The 2024-25 budget had already extended the cell-equipment waiver to EV applications; the 2026-27 budget closes the remaining stationary-storage gap, recognising that India's 500 GW non-fossil target by 2030 requires a much larger BESS build-out than originally modelled. The notification also adds 12 additional critical minerals, cobalt powder and lithium-ion battery scrap to the BCD-exempt list, building on the 25 minerals exempted in FY24-25.

2. Tariffisation (effective 1 May 2026) — critical minerals (including monazite / rare-earth concentrate) migrate from the customs-exemption notification regime into the First Schedule of the Customs Tariff Act at Nil BCD. This is structurally important: notification waivers can be reversed annually at budget time, whereas First Schedule entries require an act of Parliament to amend. It signals durable commitment and reduces policy-uncertainty risk premia for domestic processors sizing decade-long capex.

3. Processing corridors — the Budget speech commits dedicated critical-mineral and rare-earth-magnet processing corridors in Andhra Pradesh, Odisha, Kerala and Tamil Nadu. Odisha and AP have substantial monazite (REE) reserves; Kerala has the Indian Rare Earths Ltd plant at Aluva; Tamil Nadu hosts the IREL Manavalakurichi monazite operation. The corridor language complements the REPM sintered-rare-earth-magnet scheme (Nov 2025) which earmarked ₹1,345 cr in production-linked subsidies.

This is the fiscal counterpart to NCMM. NCMM funds the capex and overseas mineral acquisitions (₹34,300 cr, seven-year horizon); this Budget removes the import-duty drag on the equipment that actually materialises NCMM-funded projects. Without the BCD waivers, a typical beneficiation/refining line faced 7.5-15% landed-cost inflation on imported European, Japanese or Chinese equipment, eroding the competitiveness gains NCMM was trying to engineer.

Downstream implications

• Lower landed cost for processing capex. Domestic refiners targeting

lithium hydroxide, cobalt sulphate, separated REE oxides, and graphite spheronisation see roughly 7.5-15% reduction in equipment landed cost. Materially affects project IRRs for greenfield refining capacity.

• REPM scheme economics improve. The Nov 2025 sintered-rare-earth

magnet scheme (₹1,345 cr PLI) selects bidders; the equipment-BCD waiver lowers their capex and improves the subsidy multiplier. Watch for accelerated final investment decisions from REPM bidders post-Budget.

• BESS economics step-change. Indian BESS auctions had been running

at landed Li-ion cell costs ~25-30% above merchant Chinese cells; closing the cell-equipment BCD gap allows domestic cell makers (Reliance, Ola, Tata) to scale BESS-grade lines without a domestic-vs-import equipment penalty.

• First Schedule Nil BCD reduces reversal risk. Equity in

Indian critical-minerals processors (NALCO, HCL, GMDC, Vedanta) faces lower regulatory-reversal risk premia after 1 May 2026 tariffisation.

• Pull-through to Quad / India-Brazil minerals MOUs. The corridor

commitment in AP/Odisha/Kerala/TN gives KABIL and partner state PSUs named landing zones for off-take from Argentina (lithium), Brazil (REE / lithium — see India-Brazil critical minerals MOU, Feb 2026), and Australia (lithium / cobalt) supply lines.

• REMX / LIT thesis. Adds a fourth allied buyer of non-China

refining / processing capacity alongside US IRA §45X, EU CRMA strategic projects, Canada CMS — but with a substantially lower capex floor for participants thanks to BCD-zero on equipment.

Open questions

• Which specific HSN codes are listed under the new equipment-BCD

exemption? The Notification 02/2026 attachment is the authoritative list — currently summarised by trade press but not parsed in full here. Need to read the dojstru1.pdf attachment for the precise scope.

• Does the BESS cell-equipment exemption define BESS narrowly

(grid-scale only) or broadly (including C&I and behind-the-meter)? Definition matters for project pipeline accounting.

• Is the May 2026 First Schedule shift Nil BCD only, or does it also

bind IGST treatment? IGST is the larger landed-cost item for many intermediate inputs and is governed separately under GST law.

• How does the new exemption interact with the FTA-route imports

(Korea, Japan, ASEAN)? FTA-origin equipment was already preferential-rate; this benefits non-FTA (EU, Switzerland, US, China) origin which is where most processing equipment actually comes from.

• Will the four announced corridors (AP, Odisha, Kerala, TN) be backed

by SEZ-style tax holidays or just industrial-park land allocation? Treatment under the upcoming Special Economic Zones (Amendment) Bill is unclear.
