Trinseo issues price increases on ABS, SAN and PS in May versus April, amid firmer raw material prices.

In a note on its website the company noted that polystyrene (PS) will increase €90/mt.

Styrene acrylonitrile (SAN) and acrylonitrile butadiene styrene (ABS) will increase by €60/mt.

The increases follow yet another increase in the contract prices of the major raw material styrene in May, which went up €84/mt.

In terms of market dynamics, the PS market was relatively tight because of supply issues.

The picture was different for ABS and SAN. The SAN market has seen no change and remains well supplied.

But the European ABS market during the last few months has been gradually moving from a position of severe tightness to balanced-to-long.


Trinseo increases prices by €350-500/mt, replacing and revising up the increases announced earlier in the month.

General purpose polystyrene (GPPS) and high impact polystyrene (HIPS) will increase €350/mt.

Polycarbonate (PC) will increase €500/mt.

While styrene acrylonitrile (SAN) and acrylonitrile butadiene styrene (ABS) will increase €350/mt.

The increases, effective from 8 March, reflect the recent surge in energy prices driven by the conflict in the Ukraine.

Price Increase

Trinseo increases prices in January on PS, ABS, SAN, and PC by €155-210/mt, according to a note on its website.

Polycarbonate (PC) will increase €210/mt versus December, while Acrylonitrile Butadiene Styrene (ABS) will increase €155/mt)

Styrene acrylonitrile (SAN) will also increase by €155/mt.

Meanwhile, general purpose polystyrene (GPPS) and high impact polystyrene (HIPS) will increase €175/mt.

high prices

After the spike of more than €200/mt of the styrene contract price in November, Trinseo announces triple-digit increases on ABS, SAN, and PS.

However, the increases are more than the cost increase of the main raw material styrene. This is most probably to do with the recent surge in utility costs.

INEOS Styrolution has also announced similar increases on polystyrene (PS), namely €300/mt and higher than the increase in the styrene contract of €232/mt.

Trinseo’s increases on general purpose polystyrene (GPPS) and high impact polystyrene (HIPS) are €290/mt.

While the increase on styrene acrylonitrile (SAN) is €240/mt. And acrylonitrile butadiene styrene (ABS) is €230/mt.

There is a strong chance that the announced increases will be accepted. The markets remain highly uncertain and volatile amid supply shortages, especially for ABS but also for PS. As such, buyers may have little choice but to accept the entire increases.


Trinseo seeks utilities surcharge of €200-300/mt on styrenics and polycarbonates products from 1 November.

Trinseo will implement €200/mt surcharge on the following products: styrene monomer (SM); polystyrene (PS); styrene acrylonitrile (SAN); and acrylonitrile butadiene styrene (ABS).

However, a surcharge of €300/mt will be implemented on polycarbonate (PC), PC/ABS Resins, and ABS Long Glass Fiber (ABS LGF).

The company noted that “these surcharges are in response to unprecedented and escalating pressure from energy prices and apply to all current agreements and contracts.”

Trinseo is not the only company to have take the step to implement surcharges in response to the spike in energy prices.

Many other polymer producers are taking the same step. For example, Celanese is applying a surcharge of €500/mt on POM.

If energy prices will continue to increase amid short supply of many polymers, producers will probably succeed in passing on the extra costs.

The higher energy costs adds yet another factor fuelling volatility across the entire value chain of the polymer industry.

As the increasing turmoil in many markets reduces visibility further, many players expect a prolonged volatile period ahead.
