| Best for | Planning the current CPSC certificate-data handoff for regulated imports with the importer, finished-product certifier, customs broker, and entry records | Searching global apparel and textile production capabilities | Documenting a bounded sample-to-area yarn calculation when the equivalent area is already known and genuinely comparable with the sample | Custom-fit home sewing patterns |
| Know before using | 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 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 worksheet does not establish that a sample represents a project, derive the area of shaped pieces, account for construction or openings, prescribe reserve, supply typical project quantities, round to packages, verify label values, guarantee required quantity, check dye-lot supply, or replace a tested pattern amount. Yarn, tool, maker, strand count, stitch or texture, density, treatment, finishing, planned area, and supply decisions remain project-specific. | A generated pattern is not independent fit evidence or a production-ready graded block. The result still depends on accurate measurements, the selected design and options, ease assumptions, fabric behavior, construction, and representative test garments. An account stores saved patterns and measurement sets, so review the platform's privacy terms before retaining personal measurements. |

| What the source establishes | 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. | 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. | The worksheet performs visible proportional arithmetic on user-entered sample dimensions, sample yarn length or weight-derived length, equivalent area, and optional reserve. Craft Yarn Council pattern-writing guidance says yarn amounts and package counts should be recorded in instructions, and its consumer guidance ties project instructions to a stated yarn amount and representative gauge; those sources do not establish a universal sample-to-area method, project range, or reserve. NIST defines 1 yard as exactly 0.9144 metre for the secondary unit display. | FreeSewing's official documentation says the browser editor drafts a selected design in real time from a measurement set rather than scaling or grading a standard-size pattern. Users can adjust design options and export the generated result, including as PDF; saving the pattern to an account is optional and is used to revisit it later. |
