Quick answer
Self-translation is allowed, but the company is responsible: it must be complete and accurate, match the original page by page, name the translator and date, and carry the company chop, with consistent terminology and full business scope. A Hangzhou textile-auxiliary maker retranslated after licensed items were missed. Notarization is needed only for foreign documents or an explicit reviewer request; uncertain files can be checked by the LHLN first.
Detailed explanation
Three preconditions for self-translation
- The translator has the language and professional ability, ideally a trade or quality staff member familiar with certificate terms.
- The translation corresponds page by page, covering numbers, dates and the full business scope, with no summaries.
- Each page names the translator, completion date and contact route, and is cross-stamped with the original scan.
Where self-translations often fail
- The business scope is rendered literally, so licensed items diverge from official catalogues.
- Only the cover page of a multi-page certificate is translated; duplicates and change annexes are missed.
- Organization names and addresses appear in two renderings within one file.
Checks before submission
Lay the translation, original and customs-registered English name side by side. The Hangzhou maker runs an internal check and then an LHLN pre-check, fixing terminology before acceptance; this avoids repeated supplements caused by ambiguous wording after the file has entered review.
