| Know before using | The MRSL controls manufacturing inputs within its stated scope. One formulation status or self-generated facility inventory report does not by itself prove a complete or externally verified chemical inventory, actual order recipe, implementation, worker protection, emissions, wastewater performance, or finished-product compliance. Verify the current version, law, brand program, safety rules, formulation identity and status, complete facility and order records, inventory-verification state, and finished-product RSL and testing requirements. | 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. |

| What the source establishes | ZDHC's current scope defines the MRSL as restrictions on intentional use of listed substances in commercial chemical formulations for textile, leather, rubber, foam, adhesive, and trim processing. Covered inputs include cleaners, dyes, auxiliaries, coatings, finishing agents, maintenance, wastewater-treatment, sanitation, and pest-control chemicals. ZDHC identifies version 3.1 as the current official MRSL, distinguishes formulation conformance from finished-product restrictions, and states that an ordinary Performance InCheck facility inventory is self-generated rather than externally verified. | 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. |
