| 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. | The platform combines stakeholder-contributed, public-list, facility-claimed, and partner data with different origins and update paths. A facility record, contributor connection, claim, certification field, or shared OS ID is not a quality endorsement, ownership finding, complete supplier relationship, current capacity statement, or due-diligence result. Inspect the source badges, contributors, dates, duplicates, claimed fields, and linked evidence, then verify the facility and intended business relationship directly. | Community members add and quality-control the records, so confirm sizing, measurements, fabric suggestions, format, availability, errata, license, and purchase terms with the designer or publisher. Adding an entry to a stash does not provide the pattern files. Saved searches and private PDF storage are paid Plus features, and a listing or review does not establish pattern accuracy or fit. | The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review. |

| Access scope | Not yet reviewed at this level. | Researcher or apparel team searching production locations or operationalizing facility data. | Sewer searching pattern records or organizing patterns, projects, fabric, notions, and private files. | Not yet reviewed at this level. |
| Before an account | Not yet reviewed at this level. | Search and explore facility records without payment. The provider states that the platform is free to search, contribute to, and explore. | Browse the pattern database, guide, designers, publications, and public community areas without creating an account. | Not yet reviewed at this level. |
| Free-account boundary | Not yet reviewed at this level. | A free account supports search, contribution, profile viewing, and download of up to 5,000 production locations. | A free account needs no card and supports a stash, wishlist, projects, reviews, and personal organization. | Not yet reviewed at this level. |
| Payment boundary | Not yet reviewed at this level. | Paid products support continuous API access, custom or bulk data work, and embedded maps. Cost and commitment vary by product and scale. | Plus adds PDF pattern storage, collections, saved searches, bulk editing, and other workflow features on monthly or annual billing. | Not yet reviewed at this level. |
| Cancellation or exit | Not yet reviewed at this level. | The current solutions page does not state cancellation, renewal, or post-cancel terms for paid products. Resolve those terms in the order or contract before integration. | Cancel through an in-account link. Paid features remain through the current billing cycle, then the account returns to free features. | Not yet reviewed at this level. |
| Saved work and data | Not yet reviewed at this level. | The free account includes a bounded download; paid products add custom exports and API access. Contributor, claimed, and partner fields have different provenance and update paths. | The terms say submitted materials remain yours, but the checked public pages do not explain a full export or how stored PDFs behave after downgrade. Keep originals outside the platform. | Not yet reviewed at this level. |
| Source and review | ||||
| 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. | Open Supply Hub's current guide supports facility-name or OS ID, contributor, location, sector, parent-company, facility-type, processing-type, product-type, and worker-count searches, with contributor information visible on facility data. Manual search is open, a free account supports bounded data downloads, and paid services cover larger or programmatic access. | Threadloop's official guide describes an independent, fully crowdsourced database covering available and out-of-print sewing patterns. Its search supports pattern type, fabric type, age group, body type, cup size, level, format, file features, language, measurements, availability, and other filters; members can also track a stash, wishlist, projects, reviews, and discussions. Current terms state that the free plan requires no card, paid upgrades start billing immediately, cancellation retains paid features through the current cycle, and the account then returns to free features. | The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments. |
