Best forChemical-input controls during manufacturingStructured wool education
Know before usingThe MRSL controls manufacturing inputs within its stated scope. It does not by itself prove a facility's chemical inventory, implementation, worker protection, emissions, wastewater performance, formulation conformance, or finished-product compliance. Verify the current version, law, brand program, safety rules, chemical-product certificates and status, facility records, and finished-product RSL and testing requirements.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.

Source and review
What the source establishesZDHC'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's help centre identifies version 3.1 as the current official MRSL and distinguishes it from restrictions measured in finished products.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.
