Risk of sourcing from Ancient and Endangered Forests

Tangshan Sanyou completed and released the results of their second CanopyStyle Audit in September 2020. The audit confirmed that Tangshan Sanyou had taken immediate action to remove all known high risks in their supply chain. Through their policy implementation and audit process, the company has taken meaningful actions to improve transparency and to help fill information gaps, when incomplete raw materials sourcing information was provided by some of their dissolving pulp suppliers. 

While the audit did not fully confirm low risk, the company is engaging its supply chain partners to gather sourcing information to assess and is actively working to address sourcing risks including requiring suppliers to attain Forest Stewardship Council (FSC) certification and implement science-based conservation planning of Ancient and Endangered Forests through supply contracts. 

Tangshan Sanyou is set to commence its third audit in Fall 2022. 

Key Improvements Required

  • Complete a third CanopyStyle Audit, publish the results, and update the action plan to reflect the resulting recommendations.  
  • Accelerate the use of Next Generation Fibre Solutions in order to meet or exceed the aspirational targets outlined in the Next Generation Vision for Viscose in all its product lines.
  • Continue to engage dissolving pulp suppliers, with Canopy’s support, to confirm low risk and/or risk mitigation measures and work towards the elimination of all risk.
  • Where virgin fibres are used and they are not coming from key priority Ancient and Endangered Forests, procure higher volumes of FSC 100% certified inputs from sources that have achieved FSC Forest Management certification on the ground.
  • Provide letters to support conservation solutions in key priority Ancient and Endangered Forests.

Areas where the company is showing leadership

By taking action in a variety of different areas, Tangshan Sanyou has moved up from partial-dark green, to dark green shirt (from 27.5 to 30 buttons). 


  • Agreed to work with Canopy in a formal process to proactively avoid risk of sourcing from Ancient and Endangered Forests when looking to expand their operations or consider new sources.   
  • Increased their commitment to transparency and for the first time in 2022, published the names and locations of all suppliers. 


  • Provided a letter to support conservation solutions in key priority Ancient and Endangered Forests in 2022.  
  • Supported the call for protecting 30% of the world’s Ancient and Endangered Forests by 2030, in a letter from MMCF producers to countries that are party to the Convention on Biological Diversity (CBD). 
  • Demonstrated awareness of the status of Ancient and Endangered Forests in the countries from which they source, and efforts to protect them and engaged supply chain partners to increase large-scale conservation solutions in Canada’s Boreal Forests.
