Top 10 Companies in the Ammoniacal Copper Zinc Arsenate (ACZA) Market (2026): Market Leaders Driving Global Wood Preservation

MARKET INSIGHTS

Global Ammoniacal Copper Zinc Arsenate (ACZA) market size was valued at USD 298.7 million in 2024. The market is projected to grow from USD 312.4 million in 2025 to USD 412.9 million by 2032, exhibiting a CAGR of 4.1% during the forecast period.

Ammoniacal Copper Zinc Arsenate (ACZA) is a waterborne wood preservative that provides long‑term protection against fungal decay and insect damage. This chemical formulation combines copper as the primary fungicide, zinc as a secondary fungicide and corrosion inhibitor, and arsenic as an insecticide. ACZA is particularly effective for treating difficult‑to‑penetrate wood species and is widely used in heavy‑duty applications where durability is critical.

The market growth is driven by increasing demand for preserved wood in construction and infrastructure projects, particularly in North America and Asia‑Pacific regions. However, environmental concerns regarding arsenic content have led to stricter regulations in some markets, creating challenges for manufacturers. Key players like Koppers and Lonza continue to invest in product development to meet evolving environmental standards while maintaining efficacy.
