| Best for | Integrated pattern, marker, and 3D production workflows | Planning the current CPSC certificate-data handoff for regulated imports with the importer, finished-product certifier, customs broker, and entry records | Finding independent EU yarn or fibre dyers with off-Ravelry purchase routes | Checking which U.S. alias the current Craft Yarn Council table gives a known metric package size before confirming project gauge |
| Know before using | Pricing is not public, modules and system requirements must be confirmed, and macOS is not supported. Vendor accuracy and fit language does not prove results for an actual product. Pilot native and exchanged files with the receiving supplier, calibrated materials, approved blocks and grade rules, marker and output devices, tech-pack fields, training, version control, and risk-appropriate physical fit and production checks. | 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. | It is one curator's intentionally selective, off-Ravelry-oriented database, inventories change, and paid supporters can receive rotating priority placement; verify availability, fibre claims, shipping, and terms directly. | 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 | Optitex's current page describes 2D pattern creation, grading, verification, Tech Pack Essentials, marker creation and nesting, cut and plot output, 3D virtual samples, fabric simulation, colour and print placement, tension maps, and avatar editing. Its support page lists native and standard CAD interchange routes and states that Optitex does not support macOS. | 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 individually researched database offers free listings and sortable yarn, fibre, designer, editor, accessory, and location views; the EU page spans multiple countries and direct seller profiles. | 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. |
