| Best for | Finding a US sewing or patternmaking professional | Searching global apparel and textile production capabilities | Planning the current CPSC certificate-data handoff for regulated imports with the importer, finished-product certifier, customs broker, and entry records | Checking which U.S. alias the current Craft Yarn Council table gives a known metric package size before confirming project gauge |
| Know before using | This is a member referral directory, not a Stitch Authority roster or approval. ASDP states that it makes no representations, warranties, or guarantees and assumes no responsibility for members' products or services. Membership, a code of ethics, a profile, or referral availability does not establish credentials, experience, capacity, insurance, price, accessibility, workmanship, schedule, or project fit. Check those points, references, scope, samples, terms, and remedies directly. | The company count is a changing platform claim. Search fields, profiles, certificates, locations, and account access do not independently verify the legal entity, factory ownership, capability, capacity, certificate validity or scope, compliance performance, delivery, or project fit. Confirm the site and subcontracting, credentials with issuers, samples, audits when appropriate, specifications, contracts, and commercial terms. | 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. | The reference is not a dimensional measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, gauge result, or proof that a proposed tool will produce the required fabric. |

| What the source establishes | ASDP's public directory searches members currently accepting referrals by location and professional specialty, including patternmakers, production sewers, designers, teachers, tailors, alteration specialists, and fabric or materials suppliers. A result opens a member profile and a contact action, and the page identifies the population as association members in good standing. | FOURSOURCE's current public network page presents an operator-reported global company count and country or territory search. It says logged-in users can narrow results by compliance certificates, product groups, fabric types, target groups, minimum order quantities, and other fields, with a free-trial and supplier sign-up route. | 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. | The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows and follows the Council's warning that company letter and number labels vary; blank aliases remain blank instead of being inferred. |
