India's aluminium tariff architecture has a structural contradiction at its centre that has been quietly compressing the margins of MSME aluminium manufacturers for years — and that came to the formal policy stage in July 2026 when two major downstream industry associations submitted a joint representation to the Ministry of Mines calling for immediate rationalisation of the effective 8.25 percent import levy on primary aluminium. The Federation of All India Aluminium Utensils Manufacturers and the Cable and Conductor Manufacturers Association of India filed their joint submission on July 14, 2026, joining the Aluminium Secondary Manufacturers Association and broader downstream coalitions that have maintained similar policy positions over an extended period. For aluminium casting foundries — who sit in the same downstream position in India's aluminium value chain — the policy debate and its outcome matter directly and materially.
How the 8.25 Percent Levy Works — and Why It Hits Downstream More Than It Appears
India's basic customs duty on primary aluminium is 7.5 percent, with an additional 0.75 percent Social Welfare Surcharge bringing the effective import levy to 8.25 percent. The duty was designed with a clear upstream protection objective: to prevent cheap imported primary aluminium from undercutting the domestic smelting industry — NALCO, Vedanta, and Hindalco — whose production is the policy's intended beneficiary. The logic is straightforward: protecting domestic primary production maintains smelting investment, energy sector employment, and the upstream aluminium value chain that India's industrial development depends on.
The mechanism through which the levy affects downstream manufacturers — including casting foundries — is not the direct tariff itself but import-parity pricing. India's domestic primary aluminium producers price their output at the landed cost of equivalent imported material, inclusive of the duty margin. This means that a downstream manufacturer who purchases domestically produced primary aluminium pays a price that reflects the import protection margin — even though the metal they purchase has never been subject to import duty, was produced entirely within India, and the tariff that justifies the pricing premium was never paid on it.
The commercial consequence is that Indian aluminium casting foundries pay for primary aluminium at a price inflated by a tariff they never actually incur — and they pay this import-parity premium on every tonne of domestic primary aluminium they consume, regardless of whether they ever consider importing. The Aluminium Vision Document cited in the downstream industry submissions estimated that import-parity pricing resulted in downstream aluminium manufacturers paying approximately USD 470 million more to domestic primary producers in 2022 than they would have paid at globally competitive prices. This is the scale of the downstream subsidy to the upstream smelting industry that the 8.25 percent levy mechanism generates.
The Inverted Duty Structure — Where the Paradox Becomes Acute
The import levy on primary aluminium creates a structural paradox when viewed alongside the tariff treatment of finished aluminium goods entering India under Free Trade Agreements. India has concluded FTAs with ASEAN, Japan, South Korea, and the UAE, among others, under which finished aluminium products — extruded sections, fabricated components, and manufactured goods with significant aluminium content — enter India at zero or near-zero tariff rates. Finished aluminium product imports reached USD 4.1 billion in FY2025-26, with approximately one quarter entering under FTAs at zero or near-zero duty.
The paradox is direct: a foreign manufacturer who exports finished aluminium components to India faces no or minimal import barrier. An Indian MSME manufacturer producing the same finished components faces input costs inflated by import-parity pricing linked to the 8.25 percent primary aluminium levy. The policy inadvertently advantages the finished import over the domestically manufactured equivalent — exactly the opposite of the Make in India objective that domestic manufacturing policy is intended to advance. As one analysis of the duty structure noted, the effective burden on downstream manufacturers is significantly higher than the headline 8.25 percent rate when GST and working capital costs are incorporated, with the total cost impact rising to around 27 to 30 percent on working capital for downstream players operating on thin margins.
For aluminium casting foundries specifically, the inverted duty paradox operates through the casting export channel as well as the domestic manufacturing channel. A Kolhapur foundry exporting aluminium castings to a European customer is using domestically produced aluminium at import-parity inflated prices to produce a product that competes in the European market against Chinese, Turkish, and Eastern European foundries who access aluminium at globally competitive prices without the import-parity premium. The 8.25 percent levy does not protect the casting exporter — it disadvantages them relative to international competitors who face no equivalent upstream cost inflation.
What the Budget 2026-27 Decision Means — and What Remains Unresolved
The government's decision in Budget 2026-27 to not raise the primary aluminium import duty to 15 percent — a level that the domestic smelting industry had advocated for — was a recognition that the downstream industry's concerns have political and commercial weight alongside the upstream protection argument. Avoiding the duty increase reflected the government's assessment that higher import levies on primary aluminium would increase inflation in aluminium-intensive manufacturing sectors, elevate project costs for infrastructure programmes with significant aluminium content, and add pressure to manufacturing cost structures at a time when export competitiveness is a policy priority.
But the Budget decision not to raise the duty does not resolve the downstream industry's primary concern — which is not about a potential increase but about the existing 8.25 percent rate and its import-parity pricing mechanism. The current duty remains in place, the import-parity pricing mechanism continues to inflate domestic aluminium prices above globally competitive levels, and the inverted duty paradox — finished imports entering duty-free while domestic manufacturers pay import-parity primary aluminium costs — continues to disadvantage Indian downstream manufacturers relative to their import competitors.
The July 2026 joint submission to the Ministry of Mines represents an escalation of the downstream industry's policy advocacy from informal representations to formal ministerial submissions. The Ministry's response — and any policy adjustment that follows — will determine whether the duty structure is rationalised in a way that reduces the downstream cost burden, or whether the upstream protection argument continues to prevail in the policy balance. Foundries and downstream manufacturers who are tracking this debate should monitor the Ministry of Mines' response to the July submission, as any duty revision in the 2027-28 budget cycle would directly affect their raw material cost structure.
What Casting Foundries Can Do Within the Existing Structure
The aluminium import levy and import-parity pricing mechanism are policy-level issues that individual foundries cannot resolve within their own operations — they are structural features of the cost environment that the industry operates in. What foundries can control is how they manage their raw material strategy within this environment, and there are three levers that consistently deliver results independently of the policy outcome.
Secondary aluminium — produced by remelting scrap rather than from primary smelting — is not subject to the same import-parity pricing mechanism as primary aluminium. Secondary aluminium ingot from domestic remelters is priced at the market level for recycled metal, which reflects scrap acquisition costs and remelting energy rather than primary metal import-parity pricing. The basic customs duty on aluminium scrap is 2.5 percent — significantly lower than the 8.25 percent effective levy on primary metal — which means that secondary aluminium imported from overseas sources also faces a lower duty burden than primary. Foundries that maximise their use of verified, quality-controlled secondary aluminium — managing the composition and tramp element risks discussed in earlier blog content — reduce their exposure to the import-parity pricing mechanism that inflates primary aluminium costs.
Process scrap management — maximising the recovery and reuse of the foundry's own gates, runners, and rejected castings as internal secondary feed — is the most cost-effective raw material management lever available to any casting operation. Internal process scrap returns to the furnace at a material cost that reflects only the original purchase price of the input metal, without any markup or pricing premium. Minimising dross losses in scrap remelting, maximising the metal recovery from process returns, and reducing the rejection rate that generates scrap in the first place all contribute directly to reducing the foundry's effective raw material cost per kilogram of acceptable casting produced.
Industry association engagement — through the Institute of Indian Foundrymen, the Aluminium Secondary Manufacturers Association, or the broader MSME manufacturing coalitions that are making downstream policy representations — is the channel through which individual foundries can contribute to the policy advocacy that may ultimately address the structural cost burden. The July 2026 joint submission to the Ministry of Mines succeeded in formally placing the inverted duty concern before the relevant policy authority. Its success in generating a policy response will depend in part on the breadth of downstream industry participation in the advocacy, and casting foundries who engage through their industry associations add weight to a case that directly serves their commercial interests.
