RIL Hikes Polypropylene Prices by Up to ₹5,000/MT

Reliance Industries Limited (RIL) has raised domestic polypropylene (PP) prices by up to ₹5,000 per tonne effective September 11, 2026, one of the sharpest single-day polypropylene price hikes in India this year. The increase covers PP raffia-copolymer (RCP), injection moulding (IM), fibre and filament (F&F), and homopolymer/copolymer grades, directly raising input costs for thousands of plastic converters and packaging manufacturers across the country.

According to pricing data tracked by industry platforms, RIL increased PP RCP prices by ₹5,000 per tonne, PP IM and F&F grades by ₹4,000 per tonne, while all other homopolymer and copolymer grades went up by ₹3,000 per tonne. The move follows an earlier PVC price increase of ₹2,000 per tonne effective September 7, 2026, and a parallel polyethylene (PE) price revision by Indian Oil Corporation’s polymer division on the same date, signalling a broader upward push across India’s polymer complex in September 2026.

Why Did RIL Raise Polypropylene Prices in September 2026?

Polymer producers typically adjust domestic prices in response to international feedstock costs, naphtha and propylene spreads, and import parity pricing. Converters and market trackers note that firmer international propylene values and tightening regional supply have pushed producers to pass on costs. As India’s largest polymer manufacturer with an annual capacity of more than 5.8 million tonnes per annum (MMT) across PE, PP, PVC and PET, RIL’s pricing decisions set the benchmark that other domestic producers, including Haldia Petrochemicals and GAIL, generally follow within days.

What Does This Mean for India’s Plastics Industry?

The polypropylene price hike lands at a sensitive time for India’s plastics sector, which the Mordor Intelligence estimates will be worth roughly $47.04 billion in 2026, growing at a compound annual growth rate of 6.24% through 2031. Packaging, which accounts for over 41% of total plastics demand, is among the segments most exposed to raw material cost swings, since PP is a core input for woven sacks, BOPP films, caps and closures, and rigid packaging. Small and medium converters, who typically hold limited inventory and cannot easily pass on costs to retail brands mid-contract, are expected to feel the immediate margin squeeze most acutely.

Market Reaction and Industry Response

Trade sources tracking daily polymer pricing say downstream converters have already begun renegotiating supply contracts with brand owners to reflect the higher PP costs. Distributors report that buying interest has turned cautious, with many processors restocking only need-based quantities in anticipation of further volatility. The price move also comes as Reliance and Adani’s combined PVC capacity additions are expected to narrow India’s roughly 2.5-million-tonne local supply gap by 2027, a factor that market watchers say could eventually stabilise pricing once new capacity comes online.

What Happens Next?

Industry watchers expect other domestic producers to announce matching or near-matching increases within the next one to two weeks, a pattern typically seen after a lead producer like RIL moves first. Converters and packaging associations are likely to raise the issue at upcoming price-review discussions, particularly if crude oil and naphtha prices continue trending higher through the October-November festive demand season, when packaging and consumer goods volumes traditionally rise. Buyers should watch for the next scheduled RIL price circular, typically issued on a fortnightly basis, for signs of whether the increase holds or reverses.

Frequently Asked Questions

Why did polypropylene prices increase in India in September 2026?

Reliance Industries raised PP prices by up to ₹5,000 per tonne effective September 11, 2026, citing firmer international propylene costs and tightening supply. The increase applies across RCP, IM, F&F and homopolymer/copolymer grades.

How much did PP prices go up and which grades are affected?

PP RCP grades rose by ₹5,000/MT, PP IM and F&F grades by ₹4,000/MT, and other homopolymer and copolymer grades by ₹3,000/MT, based on RIL’s September 11, 2026 price circular.

Who is most affected by the polypropylene price hike?

Small and medium plastic converters producing packaging, woven sacks, and rigid containers are most exposed, since PP is a key raw material and many operate on thin margins with limited pricing power over downstream brand customers.
