Directorate General of Trade Remedies recommends a five-year extension of anti-dumping duties on Chinese flat-rolled aluminium and on aluminium foil from China, Thailand, Malaysia and Indonesia
NEW DELHI, September 23, 2026
India’s Directorate General of Trade Remedies has recommended extending anti-dumping duties on flat-rolled aluminium products from China and on aluminium foil from China, Thailand, Malaysia and Indonesia for a further five years, according to sunset review findings reported on September 23.
The recommended rates are substantial. On most Chinese suppliers of flat-rolled aluminium products, the investigating authority has proposed a duty of 449 United States dollars per tonne. On aluminium foil of Chinese origin, the recommended range runs from 506.81 to 976.99 dollars per tonne depending on the exporter. Thai foil producers face a recommended range of 93.53 to 339.93 dollars per tonne. Malaysian foil is recommended at 850.45 dollars per tonne.
The measures cover aluminium foil of 80 microns thickness and below, the gauge band that includes household foil, flexible packaging laminate stock, pharmaceutical blister foil and battery foil.
The recommendation is not yet law. Under Indian practice, the Directorate General of Trade Remedies investigates and recommends, and the Ministry of Finance, acting through the Central Board of Indirect Taxes and Customs, decides whether to impose. The revenue department has in the past declined to accept trade remedy recommendations, and importers should treat the recommended rates as probable rather than certain until a customs notification issues.
Background to the case
The original anti-dumping duty on these products traces to Notification No. 51/2021-Customs (ADD) of September 2021. Under the World Trade Organization Anti-Dumping Agreement and India’s implementing rules, definitive anti-dumping duties lapse after five years unless a sunset review determines that expiry would be likely to lead to continuation or recurrence of dumping and injury.
The Directorate General of Trade Remedies initiated the sunset review on September 29, 2025. The existing duty had already been extended to December 15, 2026 while the review was under way, a standard procedural step. The recommendation reported this week is the substantive outcome of that review.
The applicants included Hindalco Industries, part of the Aditya Birla group and India’s largest aluminium producer, and SRF Altech, the packaging films arm of SRF Limited. Between them the applicants represent a significant share of Indian domestic capacity in the affected product range.
This case sits within an exceptionally heavy September for Indian trade remedy activity. The same authority issued final findings on hydrofluorocarbon blends and on the HFC component R-32 from China on September 18. On September 16 it initiated a case on chlorinated polyvinyl chloride resin against Korea and China, accompanied by an anti-circumvention notification covering Malaysia, Japan and Thailand. On September 22 it initiated an anti-dumping investigation into glycine from China, registered as case number AD/OI/045/2026 and covering tariff codes 2922.49.10 and 2922.49.90. Indian trade press has reported roughly 15 final findings issued across September spanning glass fibre, steel, solar cells and chemicals.
That cadence is itself the story. India has become one of the world’s most active users of trade remedy instruments, and the aluminium recommendation is a data point in a much larger pattern.
Why aluminium, and why now
Global aluminium markets have been characterised for more than a decade by Chinese capacity that substantially exceeds Chinese domestic requirements. Downstream aluminium processing, which is where flat-rolled products and foil sit, has seen particularly rapid Chinese capacity growth, and Chinese producers have consistently placed surplus output in export markets.
The response from importing countries has been a proliferating set of trade defence measures. The European Union has anti-dumping duties on Chinese aluminium flat-rolled products and on aluminium converter foil. The United States maintains both anti-dumping and countervailing duties across a range of aluminium products. Numerous other jurisdictions have their own measures.
The consequence is a well documented phenomenon that trade remedy practitioners call cascading. When one large market closes to a producer, volumes redirect to markets that remain open, which then experience an import surge and impose their own measures. India, as a large and growing consumer of aluminium products with a domestic industry investing heavily in capacity, has been on the receiving end of that redirection.
The inclusion of Thailand, Malaysia and Indonesia in the foil case is significant and reflects the second-order version of the same dynamic. Southeast Asian aluminium rolling and foil capacity expanded substantially over the past decade, in part financed by Chinese investment, and part of that capacity was built specifically to serve markets where Chinese origin material faced duties. Whether that constitutes legitimate investment or duty circumvention is one of the more contested questions in contemporary trade remedy practice.
The anti-circumvention notification attached to the separate chlorinated polyvinyl chloride case, which covers Malaysia, Japan and Thailand, shows that Indian authorities are alert to the question across multiple product families.
Stakeholder reactions
Indian primary and downstream aluminium producers have argued consistently that the domestic industry cannot compete against material sold at prices that do not recover the cost of production. Hindalco and other Indian producers have made substantial capital commitments in rolling and foil capacity, including capacity targeted at battery foil for the electric vehicle supply chain, and the return on those investments depends on being able to sell at prices that reflect Indian cost structures.
The counter-argument comes from Indian downstream users, who are numerous and in aggregate employ more people than the producers. Indian flexible packaging converters, pharmaceutical packaging manufacturers, food processors and, increasingly, battery cell manufacturers all buy aluminium foil as an input. For them, a duty of 500 to 977 dollars per tonne on Chinese foil is a direct cost increase on a material that is a significant share of their input bill.
Indian packaging industry representatives have argued in past proceedings that domestic capacity in specific technical grades is insufficient, and that blanket duties on a product category force converters to pay protected prices for grades that are not actually produced competitively in India. The battery foil question is particularly acute, since Indian cell manufacturing is at an early stage and depends on imported foil of specifications that Indian producers are only now qualifying.
Exporters in Thailand and Malaysia will consider whether to challenge the determination. Thai producers face a wide recommended range, from 93.53 to 339.93 dollars per tonne, which indicates that some Thai exporters cooperated in the investigation and obtained individual margins while others did not. The single Malaysian rate of 850.45 dollars per tonne is high and suggests limited or unsuccessful cooperation.
Economic impact analysis
The measures affect a market of meaningful size. India’s aluminium foil consumption has been growing at high single digit to low double digit annual rates, driven by packaged food, pharmaceuticals and, increasingly, energy storage.
Converting the recommended duties into percentage terms is instructive. With aluminium foil trading in the broad range of 3,000 to 4,000 dollars per tonne depending on gauge and specification, a duty of 500 dollars per tonne is roughly 13 to 17 percent ad valorem. A duty of 977 dollars per tonne is roughly 24 to 33 percent. The Malaysian rate of 850.45 dollars per tonne lands in a similar band. These are not nuisance duties. They are large enough to reorder supply decisions entirely.
On flat-rolled products, a duty of 449 dollars per tonne against a product price commonly in the 2,800 to 3,500 dollar range implies roughly 13 to 16 percent, again commercially decisive.
The distributional effect is the familiar one in trade remedy economics. The gains are concentrated among a small number of domestic producers who can identify precisely what they gained. The costs are diffused across a large number of downstream users, each of whom absorbs a modest increase, and ultimately across consumers. The concentrated interest is better organised than the diffuse one, which is a substantial part of why trade remedy proceedings usually end in measures.
There is a second-order effect worth noting. Duties on imported foil raise the cost of Indian flexible packaging, which raises the cost of Indian packaged goods, which affects the competitiveness of Indian packaged food and pharmaceutical exports. In a heavily integrated production system, protecting an upstream sector taxes the downstream sectors that use its output. India’s pharmaceutical export sector, which is globally competitive and a significant foreign exchange earner, is a substantial consumer of blister foil.
Implications for global importers and exporters
Several practical consequences follow.
Importers into India of the covered products should model landed cost at the recommended rates immediately, while recognising that imposition is not certain. Contracts for delivery after the current duty expiry on December 15, 2026 should contain explicit provisions allocating the risk of duty imposition between buyer and seller. Failure to address this in contract drafting is one of the most common and most expensive mistakes in trade remedy exposed commodity purchasing.
Exporters in the covered countries should assess whether any legal or commercial response is available. Where a company obtained a favourable individual margin, protecting that position matters, since company specific rates are a substantial competitive asset relative to the residual rate applied to non-cooperating exporters.
Exporters outside the covered countries have an opportunity. Aluminium foil producers in the Gulf, in Turkey, in South Korea, in Japan and in Europe face an Indian market where four significant competing origins now carry duties. That margin of preference is commercially real.
Buyers globally should anticipate redirection. Volumes that can no longer profitably enter India will look for other destinations. Trade remedy authorities in Latin America, the Gulf, Africa and Southeast Asia should be expected to see increased import pressure in aluminium foil over the next 12 to 24 months, and importers in those markets should factor in the possibility of new measures where domestic industries exist.
More broadly, firms with any exposure to aluminium downstream products should treat the trade remedy environment as a permanent feature of their planning rather than an episodic disruption. The number of measures in force globally on aluminium products has been rising steadily for a decade, and nothing in the current environment suggests reversal.
The mechanics of a sunset review
Because the commercial stakes are high and the procedural detail is often misunderstood, it is worth setting out what a sunset review actually decides.
Under Article 11.3 of the World Trade Organization Anti-Dumping Agreement, definitive anti-dumping duties must terminate no later than five years from imposition unless the investigating authority determines, in a review initiated before that date, that expiry would be likely to lead to continuation or recurrence of dumping and of injury. The test is prospective. The authority is not asked whether dumping is occurring now, but whether it would resume if the duty were removed.
That prospective framing is why sunset reviews so frequently result in continuation. Once a duty has been in place for five years, imports from the covered origins have usually fallen sharply, which means present injury is often absent. The authority then reasons that the absence of injury is itself evidence that the duty is working, and that removal would restore the conditions that produced the injury in the first place. Domestic industries have learned to build their submissions around evidence of continuing overcapacity, continuing exports at low prices to third markets, and the attractiveness of the domestic market as a destination.
Exporters seeking to defeat a sunset review must therefore show something structural has changed, which is a demanding evidentiary burden. In practice, the great majority of sunset reviews in most jurisdictions result in extension.
The individual rate structure in this case tells its own story. The Chinese foil range of 506.81 to 976.99 dollars per tonne indicates that some Chinese exporters participated in the proceeding, submitted verifiable data and obtained company specific margins, while others either did not participate or had their submissions rejected and received the residual rate. The same pattern appears in the Thai range of 93.53 to 339.93 dollars per tonne, where the lowest rate is low enough to remain commercially viable and the highest is not. Malaysia’s single rate of 850.45 dollars per tonne, with no range, suggests either a single exporter or no successful individual applications.
The practical lesson for exporters is that participation pays. The cost of responding to a questionnaire is meaningful but bounded. The cost of receiving a residual rate that effectively excludes a company from a growing market is not.
The battery foil complication
One aspect of this case deserves separate treatment because it cuts across India’s own industrial policy objectives.
Aluminium foil below 80 microns includes battery foil, the aluminium current collector used on the cathode side of lithium ion cells. Specifications are demanding, with tight tolerances on thickness uniformity, tensile strength, surface cleanliness and pinhole density. The qualification process for a new supplier into a cell production line is lengthy and expensive.
India has made electric vehicle and cell manufacturing a central plank of industrial policy, with substantial production linked incentive support directed at both vehicle assembly and cell manufacturing. Several large Indian cell projects are in construction or early production.
Those projects need battery foil. Indian domestic capacity in qualified battery grade foil is limited and building. In the interim, cell makers import, and the principal sources of competitively priced qualified battery foil are exactly the countries covered by this proceeding.
This creates a direct tension between two arms of Indian policy. Trade remedy policy protects domestic aluminium rolling capacity. Industrial policy subsidises domestic cell manufacturing, whose costs rise when foil is dutied. Whether the final customs notification carves out battery grade specifications, or applies end use exemptions, or simply applies the duty across the board, will say something about how that tension is being resolved.
Indian practice has occasionally included end use based exemptions in anti-dumping notifications where domestic supply of a specific grade was demonstrably absent. Cell manufacturers and their trade associations will be pressing hard for exactly that treatment. Domestic foil producers will resist it, arguing that an exemption removes the incentive to invest in the qualification work needed to serve the segment.
Importers with battery foil exposure should be engaging with the process now rather than waiting for the notification.
The wider pattern
The aluminium recommendation should be read alongside the volume of activity from the same authority this month. Fifteen final findings in a single month across glass fibre, steel, solar cells and chemicals, plus multiple new initiations and an anti-circumvention notification, describes an administration using trade remedy instruments systematically as a component of industrial policy.
That is not unique to India. The European Commission reported on September 18 that it had opened 30 trade defence investigations over the preceding year, almost three times its historical average. Trade remedy activity is rising across most major jurisdictions simultaneously.
The common driver is the same in each case, which is the redistribution of manufacturing surplus, principally but not exclusively Chinese, into whichever markets remain open. Each individual measure is defensible on its own terms under World Trade Organization rules. The aggregate effect is a steadily thickening layer of product specific and origin specific duties that makes global sourcing progressively more complicated and more expensive.
For importers and exporters, the operational implication is that trade remedy exposure has to be managed as an ongoing function rather than handled reactively when a duty lands. That means monitoring initiations in every market a firm ships into, participating in proceedings where the firm has a material interest rather than ignoring questionnaires, and building duty risk into pricing and contracting as a matter of routine.
It also means treating classification with the seriousness it deserves. Anti-dumping duties attach to a described product, and the description in this case, aluminium foil of 80 microns and below, draws a line that some products sit very close to. Foil at 78 microns is covered. Foil at 85 microns is not. That kind of threshold invites both legitimate product redesign and illegitimate misdeclaration, and customs authorities know it. Importers should expect scrutiny of gauge declarations and should be able to substantiate them with mill certificates and independent measurement where necessary.
The same applies to origin. Duties attach to goods originating in the named countries, and non-preferential origin rules determine where a good originates for this purpose. Aluminium foil rolled in one country from coil produced in another raises a substantive origin question, and the answer depends on whether the rolling operation confers origin under the applicable rules. Importers who assume that the country of shipment is the country of origin are exposed, and retrospective duty assessments in these cases can run to several years of entries.
Finally, firms should recognise that the four covered origins in the foil case account for a large share of internationally traded foil capacity. The set of unaffected alternatives is not unlimited, and availability from those alternatives at the volumes Indian converters require cannot be assumed. Sourcing teams should be qualifying alternative mills now rather than after the notification issues, because qualification takes longer than the gap between recommendation and imposition.
The Central Board of Indirect Taxes and Customs will now decide whether to accept the recommendation. On recent form, acceptance is more likely than not, and the market should plan accordingly.
