Improving the sustainability of our products

In 2019 THOM developed a strategy to improve the sustainability of its products so as to encourage more responsible consumption and reduce its environmental footprint. This strategy is based on 4 pillars:

• Defining technical specifications, updated on a yearly basis, to ensure the strength and therefore the durability of products. For example: strength of chains and clasps, quality of setting, metal finish, etc. The return rate of products due to quality issues is 3.26% for 2025 (compared to 3.64% for 2024), which represents an improvement of 10%.
• Conducting on-site quality control at the end of production. In FY25, 100% of production was subject to quality control by suppliers. 7.7% of shipments were additionally inspected by THOM at the suppliers’ premises prior to shipment (compared to 6.8% in FY24).
• Implementing product improvement program (launched in 2023), focusing on the quality enhancement of the most defective and best-selling items on a quarterly basis.
• Performing regular in-depth analysis of defects or weaknesses observed in real-life situations by our teams and customers, to continuously improve product quality.

In 2025, THOM made significant investments in optimising product quality, reducing the number of customer returns due to defects. Over 350,000 pieces are inspected each year. The result of this process has been a consistent reduction in the rate of defective products returned across all of our brands in 2025, confirming the crucial role of our quality control strategy. In 2026, the Group will carry out further investments to modernise its quality control systems.
