Aluminium Price Today Kolkata — April 30, 2026

Aluminium Price Today Kolkata in the Local Market

For buyers in Kolkata, the aluminium price today Kolkata usually matters more as a practical buying rate than as a headline number. A fabricator in Howrah, a trader in Burrabazar, and a contractor sourcing sheet for site work all care about the same thing: what the metal will cost after freight, taxes, and conversion are added. The live benchmark on this page sits at ₹0.31 and changes with the broader Indian aluminium market.

The raw price still starts outside the city. MCX aluminium futures give the Indian reference, while LME aluminium sets the global tone. By the time the metal reaches a Kolkata stockist, the number already reflects exchange movement, rupee swings, and the cost of getting stock into eastern India. That is why the same alloy can look cheap on a chart and feel expensive at the warehouse gate.

• 1 gram: ₹0.31
• 10 grams: ₹3.10
• 100 grams: ₹31.00
• 1 kg: ₹310.00
• 1 metric tonne: ₹310,000.00

That tonne figure is the one serious buyers watch. Aluminium is fundamentally a bulk industrial metal, so the per-kg and tonne numbers tell the real story far better than a decorative per-gram quote ever will.

Why the Kolkata Aluminium Rate Moves the Way It Does

The Kolkata aluminium rate does not move in isolation. It follows the imported benchmark first, then the domestic market catches up. LME grade A aluminium is the global reference for primary metal, and Indian pricing is usually built from that base after USD conversion, basic customs duty of roughly 7.5%, GST, and local logistics are folded in. One sharp rupee move can change the final price more than a quiet day on the exchange.

Primary metal, scrap and alloy stock do not trade at the same level

Primary aluminium costs more because it begins with smelting from bauxite and finishes as a clean, consistent grade that matches exchange specifications. Secondary aluminium, which comes from scrap, usually trades at a discount. The spread is not fixed. Clean scrap, melting loss, contamination, and alloy mix all matter. A batch of 6061 extrusion stock will not price the same way as plain 1100 series material, and any Kolkata buyer who handles both already knows that from experience.

Demand also matters, and not in some abstract textbook way. Packaging plants need foil and can stock. Builders need sheet, coil and section material for facades and window frames. Cable makers need high-conductivity metal. On top of that, China still produces roughly 60% of the world’s primary aluminium, so any change in Chinese smelter output or power costs can shake the whole market. That is why a Kolkata buyer should not look only at the local quote; the real pressure comes from global supply, energy tariffs, and industrial demand running through the supply chain.

What Buyers and Traders Should Watch Next

Aluminium stays cyclical. It rises when construction picks up, when packaging demand gets busy, and when the market begins to price tighter supply. It softens when industrial demand slows or when smelter output catches up. Kolkata traders who track the metal daily usually keep one eye on MCX aluminium futures and another on LME aluminium spot because the spread between the two often tells you more than the headline price itself.

Seasonality still has a place in this market. Construction usually improves before the summer peak, monsoon slows on-site work, and festive-season packaging demand can add a bit of support later in the year. None of that creates a straight line, of course. One quiet freight market or a stronger rupee can blunt the move quickly. That is the part people forget when they try to read aluminium like a simple retail commodity.

Domestic capacity matters too. India has been building out smelting and downstream aluminium production for years, with major names such as Hindalco and Vedanta keeping the market supplied. Even so, imported metal and global pricing still influence the Kolkata market heavily. For industrial buyers, the best habit is plain enough: watch the exchange, watch the dollar, and never assume yesterday’s number will still hold by lunchtime.
