| Best for | Checking GOTS certification records | Reading current or vintage crochet-hook sizes without using an unsupported universal UK or Canadian conversion or assigning one hook from yarn category alone | Auditing inherited grade rules or controlling a new multi-size pattern release from approved targets through sample evidence |
| Know before using | A company result is not a blanket approval; confirm the certificate scope, validity, facility, process, product, and transaction documentation for the exact purchase. | The record does not inspect a physical hook, establish a universal UK or Canadian crosswalk, select a hook, rank handle or material ergonomics, approve a gauge or fabric, diagnose pain, or replace the pattern publisher, tool and yarn makers, qualified instruction, or healthcare and accessibility support. | The record does not create a production grade, supply universal increments or breakpoints, validate a CAD file or fit population, reproduce licensed standards, or replace qualified anthropometric, pattern, technical-design, fit, quality, accessibility, safety, statistical, and user-research review. |

| What the source establishes | The official GOTS search exposes certified entities by country, field of operation, product category, and certification detail, including processing and trading scopes. | The guide cites the current Craft Yarn Council regular-hook, steel-hook, yarn-weight, and FAQ guidance; it follows the Council's metric-first and company-variation boundaries and requires source-specific interpretation plus a project specimen for regional or vintage notation. | The guide cites current ISO body-table, size-designation, and garment-measurement boundaries plus two peer-reviewed studies that tested the relationship between conventional grade rules, anthropometric evidence, and garment fit; it requires product-specific target deltas and validation instead of publishing universal increments. |
