Mulhouse, March 16th, 2026

Due to the recent closure of the Strait of Hormuz and the resulting disruption in global supply chains, the cost of several key raw materials used in additives production has increased significantly.

As a result, a price increase of 15–20% will be implemented for selected additives, including ADK STAB AO-50 grades, ADK STAB AO-60 grades, ADK STAB 2112 grades, binary blends containing these products, ADK STAB AO-40, ADK STAB PEP-8T, ADK STAB FP-600S and liquid phosphites.

The adjustment will be effective starting from April 2026.

This revision reflects the current increase in raw material costs and does not yet fully incorporate the ongoing escalation in freight costs. Market conditions continue to be closely monitored, and further updates will be communicated as necessary.
