| Best for | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Planning the current CPSC certificate-data handoff for regulated imports with the importer, finished-product certifier, customs broker, and entry records | Researching loom-ready weaving structures and drafts |
| Know before using | A shared nominal diameter does not make a knitting needle and crochet hook interchangeable or predict equal gauge or fabric. The reference is not a physical measurement, manufacturer inspection, UK or Canadian conversion, steel-hook chart, tool recommendation, yarn assignment, or project approval. | 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. | A visible drawdown is not automatically a complete, corrected, rights-cleared, or loom-compatible project plan. Full draft data and advanced tools require a renewing subscription, and historical sources can contain errors or unclear provenance. Check shafts, treadles, tie-up, sett, yarn, floats, repeats, copyright status, and WIF compatibility before committing a warp. |

| Source and review | |||
| What the source establishes | Rechecked July 28, 2026. The lookup reproduces the current public Craft Yarn Council metric and U.S. alias rows, aligns hooks and needles only when their nominal millimetre value matches, and leaves missing rows or aliases unfilled. | 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. | Handweaving.net currently exposes the Ralph Griswold digital archive, document downloads, draft drawdown views, basic-account clipboards, and video tutorials without a paid subscription. Its subscription page reserves full drafts, WIF downloads, draft creation and editing, color tools, profile and block substitution, arrangement, repeats, and related browser tools for subscribers. The current page states that plans renew until canceled, cancellation takes effect at the next renewal, access remains until then, and refunds are not offered. |
