India probes Chinese, Malaysian, Vietnamese and Thai aluminium dumping
India's trade watchdog has launched an anti-dumping investigation into aluminium extrusion imports from China, Malaysia, Vietnam and Thailand following a complaint from domestic manufacturers.
The Aluminium Extrusion Manufacturers Association of India has formally requested an anti-dumping probe into imports from four Asian countries. The Directorate General of Trade Remedies initiated a suo motu investigation on November 9, 2026, based on representations from ALEMAI, which represents 228 manufacturers of aluminium extrusion profiles, structures and articles.
These products are used in industrial, transport, electrical and engineering applications. They include windows, doors, railings, solar mounting structures, and bicycle parts. The finance ministry will make the final decision on whether to impose duties.
DGTR confirms investigation scope and timeline
The Directorate General of Trade Remedies has opened a formal investigation covering aluminium extrusion products from April 2025 to June 2026. The probe period spans 15 months. The notification was published on November 10, 2026. Nine domestic producers who are members of ALEMAI have sought anti-dumping duties.
Domestic industry seeks relief from dumped imports
Indian manufacturers report significant profitability declines and underutilized capacity due to low-cost imports. The domestic industry is largely fragmented and comprises micro, small and medium enterprises. It has suffered injury due to dumped imports, including a significant decline in profitability and losses. The industry is facing a decline in cash profits and return on capital employed. It is also experiencing significant underutilization of production capacities. The DGTR stated that it is prima facie observed that the domestic industry has suffered injury.
Methodology and procedural details
The DGTR will calculate normal values using Indian production costs and determine duty amounts based on transaction-adjusted import pricing. It constructed normal values for all four countries using production-cost information from three Indian manufacturers. Export prices were calculated using transaction-wise import data after adjusting for freight, port expenses, bank charges and commissions. The investigation will determine the existence, degree and effect of alleged dumping and recommend anti-dumping duty amounts. Three producers submitted cost information and estimates of dumping and injury margins.
The product scope under investigation is broad.
Current trade defence landscape
India has previously imposed anti-dumping duties on other imported goods under WTO rules. All countries involved in the probe are World Trade Organization members. Anti-dumping duties are imposed under the WTO multilateral regime. India has already imposed anti-dumping duties on several products to address cheap imports. An anti-dumping duty is already in force on imports of anodised aluminium frames for solar panels and modules from China, imposed in September 2024.
Countries conduct anti-dumping probes to determine if domestic industries have been hurt by cheap import surges. The DGTR will publish its preliminary findings after the 37-day submission window closes.
