Top 10 Companies in the Acid Copper Chromate (ACC) Market (2026): Market Leaders Powering Global Wood Preservation

MARKET INSIGHTS

The global Acid Copper Chromate (ACC) market was valued at USD 173.5 million in 2025 and is projected to reach USD 233.5 million by 2034, exhibiting a CAGR of 4.4% during the forecast period.

ACC is a wood preservative primarily used for pressure‑treated lumber, offering protection against fungal decay and insect damage. It belongs to the class of copper‑based preservatives that have gained prominence due to their effectiveness and relatively lower environmental impact compared to older arsenic‑based alternatives. The market’s growth is driven by increasing construction activities, particularly in residential and commercial sectors, alongside rising demand for durable outdoor structures.

North America currently dominates the market, holding over 45% of the global share, followed by Europe and Asia‑Pacific. The United States remains the largest consumer, driven by its robust construction industry and the widespread use of pressure‑treated wood in decking, landscaping, and structural applications. Stringent regulations regarding wood preservation, particularly in North America and Europe, also contribute to market growth by mandating specific treatment standards for various applications.

However, the market faces challenges from alternative wood treatment technologies and non‑wood materials. The shift towards more environmentally friendly preservatives may also impact certain segments. Nonetheless, the cost‑effectiveness and proven performance of ACC ensure its continued relevance, particularly in regions with high humidity or termite pressure.

The market is segmented by application into decking, landscaping, construction, and others. Decking represents the largest segment due to the high demand for outdoor living spaces and the need for durable, low‑maintenance materials. The landscaping segment is growing rapidly, driven by increased investment in public parks, gardens, and commercial landscapes.

Key players include Koppers Inc., Lonza Group, Viance LLC, Dolphin Bay, Goodfellow, Jinan Delan Chemicals, CRM Yingtan, Foshan Liyuan Chemical, Boda Biochemistry, and Jinan GreenChem.
