Do you believe recent price increases for raw materials justify higher costs for finished consumer goods?
Polyethylene producers successfully implemented a 5 cents per pound contract price increase across the US and Canada in September 2026. This move followed a surge in export prices and rising global feedstock costs.
Why it matters
Rising export prices and supply concerns fueled by the US-Iran war have supported higher domestic costs for manufacturers. Producers are now looking to build on these gains by announcing additional contract increases for October.
Polyethylene contracts settled 5 cents per pound higher in September, while US export prices rose by 4 to 8 cents per pound between September 2 and 9. Producers have now announced further increases of 7 cents per pound for October contracts.
The details
Manufacturers maintained firm pricing despite notable buyer resistance throughout the month. Export pricing saw specific spikes, including an 8 cents per pound increase for high-density polyethylene high molecular weight film and a 4 cents per pound rise for linear low-density polyethylene butene.

Macro View
The rise in plastics prices follows a pattern set by the impact of the US-Iran war on global crude oil supply, which currently dictates energy and feedstock costs. This trajectory mirrors historical inflationary environments where geopolitical instability directly translates into higher industrial material costs.
The increase in contract prices will likely lead to higher manufacturing costs for businesses relying on polyethylene materials. Consumers may eventually see these costs passed down through price adjustments on a wide range of plastic-based retail goods.
The takeaway
Manufacturers should prepare for continued upward pressure on material costs as producers push for a 7 cent increase in October. Businesses may benefit from diversifying suppliers to navigate the firm pricing environment sustained by current supply concerns.
