Non-mulesed Wool
Non-mulesed wool is a sourcing term for wool obtained from sheep that have not undergone mulesing, the removal of skin around the sheep's hindquarters.

Definition and Positioning
Non-mulesed wool is not a term that indicates the wool’s place of origin, fiber fineness, or the fabric structure of woven or knitted textiles. It is a sourcing term related to animal welfare that indicates wool derived from a flock of sheep that has not undergone mulesing, a procedure sometimes carried out in sheep health management.
Mulesing is a procedure in which skin around a sheep’s hindquarters is removed to help prevent flystrike. In non-mulesed production, sheep health is managed by combining measures such as livestock environment control, shearing, and pest control. The fact that it is not carried out does not uniformly indicate the full details of the entire raising process.
How Certification and Standards Are Viewed
Non-mulesed is not, by itself, the name of a single certification or legal regulation. Because it is verified based on conditions in the place of origin, supplier declarations, and third-party certification standards, the criteria used for the term and the verification method may differ by trading partner.
For materials with third-party certification, the handling of mulesing, as well as sheep husbandry, land management, and supply chain control of the material, may also be part of the standard. On the other hand, supplier proof alone may limit the scope of verification and traceability. It is important not to treat a certification name and a non-mulesed claim as having the same meaning.
Points to Check When Purchasing Fabric and Making Products
When purchasing fabric, confirm whether all of the wool is covered or only part of the blended wool is covered. For blended products, confirm the blend ratio, the proportion of the covered material, and the supply chain to the fabric, and align the wording in the planning sheet, purchase order, and product specification sheet.
As supporting documents, confirm the supplier’s declaration, traceability documents, and the relationship between applicable certificates and transaction documents. Even when there is a certificate, you need to confirm the issuer, validity period, covered organization, covered items, and the link to the fabric or product lot you are ordering.
Being non-mulesed does not guarantee physical properties such as hand feel, strength, shrinkage rate, or dyeability. Depending on the application, separately confirm the wool type, blend ratio, fabric weight, structure, and suitability for washing or dry cleaning as part of normal fabric specifications.
- Blend ratio and scope of the target wool
- Issuer and validity period of supporting documents
- Whether there are documents that can trace back to the fabric or product lot
- Wording used on hangtags, product pages, and care tags
Notes on Labeling and Certificates
Labels such as “uses non-mulesed wool” should not go beyond the verifiable scope of the material. For example, if only part of the material is covered, avoid wording that could be understood as applying to the entire product, and clearly state the applicable material and blend ratio in line with the specifications.
The claim of non-mulesed is separate from fiber composition labeling under the Household Goods Quality Labeling Act. Composition must follow the prescribed labeling rules, and voluntary claims about sourcing should be made while retaining objective supporting documents and following the conditions for using certification names and marks.
Differences from Similar Terms
Wool is the material name for all animal fibers obtained from sheep, while non-mulesed is a term related to sourcing conditions. Merino wool refers mainly to wool from Merino sheep, so even if it is Merino, whether it is non-mulesed must be confirmed separately.
RWS is one of the certification standards for wool production and distribution. It is not a term that refers only to the single point of non-mulesing, and when using certification in labeling, confirm not only whether the certification exists, but also the covered product and the scope of labeling permission.
Frequently Asked Questions
Is non-mulesed wool the name of a certification?
No. In general, non-mulesed is a term indicating wool from sheep that have not undergone mulesing. Because it is not a single unified certification name, confirm whether it is based on the supplier’s declaration or on third-party certification, and check the scope of verification and supporting documents individually.
Can Merino wool be labeled as non-mulesed wool?
No. Merino wool is a material name related to the breed of sheep and does not indicate whether mulesing was carried out. Even if the material is from Merino sheep, supporting documents that confirm no treatment was performed on the target material are required in order to label it as non-mulesed.
What should be noted when labeling blended fabric as non-mulesed wool?
First, confirm the wool blend ratio and whether all of that wool is derived from non-mulesed sources. If only part is covered, use wording that makes the covered scope clear, and manage it separately from the composition labeling. Even after the product is made, it is important to keep the fabric lot and certificate documents linked and stored together.
