| Best for | Finding the current CYC hook and needle aliases that share one known nominal metric diameter before confirming project gauge | Starting a fabric decision before purchase or cutting | Planning the current CPSC certificate-data handoff for regulated imports with the importer, finished-product certifier, customs broker, and entry records |
| 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. | Source-reviewed describes the page and its cited decision boundaries. It does not authenticate a commercial roll, seller claim, fibre percentage, construction, finish, performance result, machine setting, care route, compliance status, supplier, or product fitness. Internal browse bands are navigation labels, not textile standards or product classes; an entry without a usable listed mass range is unclassified. Check the actual article, seller data, care label, equipment instructions, representative assemblies, applicable rules, and project requirements before deciding. | 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. |

| 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. | All 50 current cloth entries meet the source-reviewed content contract. The public index, cards, permanent pages, and site search expose that state, while the repository audit enforces a current review date, substantive scope, decision boundaries, and at least three external sources. The migrated cases cover fibre and family representations, woven and knitted construction, open nets, raised and dimensional surfaces, mass, thickness, drape, elasticity, colour, seams, pressing, care state, supports, and complete-product decisions. | 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. |
