Responsible Wool Standard Certificate

Material origin

Wool in the product originates from farms independently certified to the Responsible Wool Standard for animal welfare (including a prohibition on mulesing) and land management practices, with chain-of-custody certification (scope and transaction certificates) tracking the certified wool through each supply-chain stage.

You might see it written as: Responsible Wool Standard · RWS Certified · RWS Certified Wool · Textile Exchange Responsible Wool Standard

Issued by: Textile Exchange (standard owner; certification via approved bodies such as Control Union)

What it proves

Wool in the product originates from farms independently certified to the Responsible Wool Standard for animal welfare (including a prohibition on mulesing) and land management practices, with chain-of-custody certification (scope and transaction certificates) tracking the certified wool through each supply-chain stage.

What it does not prove

  • Organic wool claims — RWS is a welfare and land-management standard, not an organic standard.
  • Chemical-safety claims about dyeing, finishing, or the final textile.
  • Claims for products whose supply chain lacks valid scope and transaction certificates at every stage.

Expiry matters — check the certificate is current.

Every stage from farm to final product needs chain-of-custody coverage; a broken chain breaks the claim.

Check the certified wool percentage — blended products may contain a mix of RWS and non-RWS wool.
