| Know before using | AFIRM states that its list is guidance, not legal advice, an industry standard of care, or a guarantee of completeness or brand acceptance. It does not replace current law, a customer's stricter RSL, manufacturing-input controls, a product-specific risk and sampling plan, accepted laboratory methods, supplier controls, or performance and safety testing. | A suggested match is a data-based shortlist, not proof that the yarn suits the pattern or maker. Records can be incomplete or wrong, price bands are approximate, availability varies by country and seller, and shade-level matching is unavailable. YarnSub says affiliate status does not change suggestions, but equally rated matches are ordered by brand popularity. Confirm required gauge, total length, fibre behavior, construction, care, colour, dye lot, accessibility, price, availability, and seller terms, then make and assess a representative swatch before committing. | The record does not supply universal POM values, validate fit across a population, prove process capability, choose a statistical study or sampling plan, reproduce licensed standards, or replace qualified technical, fit, quality, statistical, safety, compliance, and legal review. |

| Source and review | |||
| What the source establishes | AFIRM's current About page identifies the Apparel and Footwear International RSL Management Group as a member-driven organization collaborating on chemicals management and assigns annual RSL maintenance to its RSL Committee. AFIRM publishes a 2026 multilingual Restricted Substances List for chemicals in finished apparel, footwear, accessories, and related materials, with a material-specific testing matrix. Its FAQ says the list does not cover product-performance testing, distinguishes the finished-product RSL from manufacturing-input lists, and tells suppliers to check each customer's brand-specific requirements and testing acceptance. | 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 suggestions. Result filters can exclude animal, animal-derived, synthetic, or plant fibre groups and use a subjective $ to $$$$$ price indicator. The site does not accept user-entered yarn details, individual shade cards, or expose an API. Each yarn page provides a data-issue route. | The guide cites current ISO, AATCC, and NIST sources for body and garment measurement boundaries, textile conditioning, dimensional-change testing, repeatability and reproducibility, and AQL-indexed sampling, while requiring the live product owner to set rather than inherit numerical tolerances. |
