Why certifications matter when sourcing wool
The wool market includes many certifications with different scopes and standards. Brands often lack clarity on how certifications compare or which are best suited to their goals. Without this understanding, sourcing decisions can be inconsistent or misaligned with a brand’s ambitions.
Certifications differ in kind: farm-level verifications, value-chain standards, and practice-based versus outcome-based regenerative frameworks. Many standards guarantee non-mulesed wool; beyond that, some set stricter animal welfare requirements, some trace the wool through the value chain, and some add regenerative requirements based on practices or on measured outcomes. Many brands put full supply chain traceability and non-mulesed wool first, yet they often find that traceability promised to the farm does not reach it.
The landscape is also changing. Textile Exchange’s Responsible Wool Standard (RWS) is being replaced by the Materials Matter Standard (MMS), which deepens the requirements on human rights and worker livelihoods through a risk-based due diligence approach. Farms can choose either standard during 2027; the new standard is mandatory from 1 January 2028.
Key takeaways for brands
- Decide what matters most to your brand before choosing a certification. For many brands that is traceability and non-mulesed wool; for others it is land management or consumers’ trust.
- Ask how far a certification’s traceability really goes. Many promise traceability to the farm, but brands often find they cannot get to farm level; find out whether you can know the farms your wool comes from.
- Plan for the move from the Responsible Wool Standard to the Materials Matter Standard: farms can certify to it during 2027, and every audit must use it from 1 January 2028, with more detailed requirements on human rights and livelihoods at farm level.
- Ask your suppliers whether their farms are audited for several standards in one visit, and which schemes recognise each other’s audits. Dual certification reduces the burden on growers.
