| Know before using | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. | This is Woolmark-operated education focused on wool, not a neutral comparison of all fibres or processing systems. A completion badge records coursework, not independent proof of production competence, product performance, environmental impact, or compliance. Confirm technical values and local requirements against current standards before production use. | The portal does not decide whether a product requires certification, identify the correct rules or certificate data, classify an entry, replace the current 16 CFR part 1110 text, or reconcile a filing to an actual shipment. Effective dates and workflows differ by entry route; use current CPSC, CBP, customs, product-safety, and legal review. | A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Yarn records can be incomplete or wrong, prices and availability vary by market, and the site uses affiliate links. Confirm the required gauge, total length, fibre behavior, construction, care, color, dye lot, accessibility, and seller terms, then make and assess a representative swatch before committing. |

| What the source establishes | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. | The current Woolmark Learning Centre library publishes free account-based coursework with module counts, completion times, progress tracking, knowledge checks, and supporting resources. Its wool programs cover fibre science, raw-wool and yarn processing, dyeing and finishing, woven textiles, knitwear, product quality, and wastewater management for learners and facilitators. | CPSC operates the eFiling portal with role-specific importer, broker, applicability, Product Registry, regulated-product, laboratory, ACE, FAQ, video, and document-library routes. The certificate final rule took effect July 8, 2026 for covered non-FTZ products, with separate timing for covered FTZ entries. | YarnSub's official FAQ says its matching software compares gauge, texture, yarn weight and density, fibre content, and fibre qualities such as drape and softness. Discontinued yarns remain searchable as starting points but are excluded from suggested replacements, and each yarn page provides a route to report source-data problems. |
