International Wool Textile Organisation

What International Wool Textile Organisation does

The International Wool Textile Organisation (IWTO) is an international non-profit association (aisbl) established in 1930 and headquartered in Brussels, Belgium. It functions as the recognized global authority for wool textile standards, serving the complete wool value chain—from sheep farmers and wool producers through traders, top-makers, spinners, dyers, weavers, and knitters to brands and retailers. Its core deliverables include the Green Book (the consolidated compendium of industry standards), Wool Testing Standards, Wool Sheep Welfare Specifications, and Wool Life Cycle Assessment Guidelines, alongside statistical publications, the Wool Review, fact sheets, and the Recycled Wool Directory. The organization runs an Annual Congress (the 95th edition drew 238 participants in Dalang, China in June 2026), the Wool Round Table working committees, the Young Professionals program, and accredits licensed wool-testing laboratories worldwide. The organization generates revenue through membership dues from corporate members across the wool pipeline, event registration and sponsorship income from the Congress and Round Tables, and licensing/recognition fees from accredited wool-testing laboratories that adopt IWTO testing standards. Social media presence spans Facebook, X, LinkedIn, YouTube, and Instagram, and the organization operates under GDPR-compliant data practices.

Expansion highlights4 records

Direct peers

• International Cotton Advisory Committee (ICAC): Intergovernmental body for cotton countries covering statistics, research, and policy. Directly comparable to IWTO as a parallel fiber-specific international organization with analogous standards, statistics, and member-driven governance.
• Textile Exchange: Non-profit focused on sustainable textile standards (RWS, GRS, OCS, GOTS). Directly comparable to IWTO as a standards-setter and certification body for the fiber/textile industry, with overlapping ESG and traceability content.
• International Sericultural Commission (ISC): Intergovernmental body for silk-producing countries covering research, standards, and market data. Closely analogous to IWTO in scope and structure for a different natural fiber category.
• Confédération Européenne du Lin et du Chanvre (CELC): European agro-industrial organization representing the linen and hemp industry. Comparable to IWTO as a natural-fiber trade body that promotes sustainability, traceability, and technical standards for a competing natural fiber.

Others

• International Organization for Standardization (ISO): Global standards body whose ISO/TC 38 covers textiles. IWTO's testing standards must coexist with ISO textile methods, making it a governing/overlapping body rather than a direct competitor.
• ASTM International: Global standards development organization covering textiles among many industries. Related to IWTO as a standards body whose textile committee methods can intersect with IWTO's wool testing standards.

Broad incumbents

• The Woolmark Company: Subsidiary of Australian Wool Innovation that promotes wool globally and licenses the Woolmark quality symbol. Comparable to IWTO as a wool industry authority, though more brand/marketing focused than IWTO's standards and testing focus.
• Sustainable Apparel Coalition (SAC): Industry coalition behind the Higg Index, covering sustainability measurement across apparel and footwear. Comparable to IWTO in promoting sustainability standards, though broader in scope and brand-led rather than wool-specific.
• International Textile Manufacturers Federation (ITMF): Global textile industry federation based in Zurich that represents the entire textile value chain (spinning, weaving, knitting, etc.). Comparable to IWTO as a parallel international trade body, though ITMF covers all fibers rather than specializing in wool.

Regional players

• British Wool: UK-based farmer-owned wool marketing organization. Comparable to IWTO as a wool industry body, but operating at a national level rather than global, focused on collection and grading rather than international standards.
