Iran’s Barez Industrial Group has disclosed that it will raise the average selling price of its radial tyres by 21% from Monday, 19 October 2026. The company cited higher raw-material, labour and other production-input costs. Radial tyres generated 64% of the company’s sales revenue in the previous financial year, making the adjustment material for the tyre supply chain.
The announcement follows a separate price increase by another Iranian tyre maker and suggests that cost pressure is becoming sector-wide rather than company-specific. Carbon black is a key tyre ingredient: it provides colour, reinforcement, abrasion resistance and longer service life. Barez did not disclose its carbon black purchase volumes or prices, so the effect on domestic carbon black demand must still be tested against monthly production and sales data.
Analysis of this news
A 21% selling-price increase can help transfer part of the cost shock to the market, but it does not guarantee a matching rise in profit. The outcome depends on sales volumes, demand elasticity, product mix, inventory valuation and the timing gap between raw-material purchases and tyre deliveries. For carbon black suppliers, the immediate signal is that tyre manufacturers are attempting to restore purchasing power after a sharp rise in operating costs.
Two scenarios matter. If tyre demand remains resilient, the revised prices may protect production schedules and sustain procurement of reinforcing grades. If end users delay replacement purchases, tyre output and therefore carbon black consumption could soften despite higher nominal prices. Suppliers should watch Barez’s October and November production reports, inventory trends and disclosures from other manufacturers.
In this environment, shorter quotation validity, price-adjustment clauses and closer credit monitoring become more valuable. The disclosure is therefore a useful demand-chain indicator, but not proof of higher carbon black consumption on its own.
