The Sustainable Leather Foundation is a UK-based, not-for-profit organisation focused only on the leather value chain. Its audit standard assesses leather companies against the three pillars of sustainability (environmental, social and governance) and shows the results on the SLF Transparency Dashboard™, so brands and consumers can see a facility’s performance at a glance. SLF also maps a facility’s existing third-party certifications onto the dashboard, so it complements rather than duplicates schemes such as the Leather Working Group.
Saigon TanTec has been an SLF partner since November 2025. Its partner profile covers leather manufacturing from tanned to finished leather, for use in leather goods, and shows every audited area across the environmental, social and governance modules as passed.
In the 2026 audit, Saigon TanTec reached the higher “Passed Plus” level in eight areas: three under Environmental Responsibility and five under Governance Responsibility, including ethical business practice, animal welfare practices, and occupational health and safety.
