Shelf Life有效期
Shelf life is the period during which a medicine, biologic, or medical device remains stable and fit for its intended use under specified storage conditions after release. In localization work, the term appears on labels, package inserts, stability study reports, specifications, and certificates of analysis, often with date formats and storage instructions that must be adapted without changing the product's approved expiry claim.

Where this term appears
Translators encounter shelf life in labeling artwork, package inserts, regulatory submissions, stability reports, and product information updates that support global launches. The wording around shelf life often includes conditional storage statements and expiry dating, so translation must match local date conventions while ensuring that the approved time period, storage range, and special handling instructions remain unchanged.
Translation checks
A common error is translating the expiry period as a fixed calendar date or re-formatting it incorrectly, which can make a product appear expired earlier or later than intended. Another error is omitting storage conditions such as 'do not freeze' or 'store below 25 °C,' changing the basis of the stability commitment and creating usability risk.

Check the distinction in context
Shelf life, an expiry date and an in-use period describe different things. Retain the source distinction and its storage conditions. A Chinese label should not turn a fixed expiry into a duration or omit the condition attached to a period.
Check the returned Chinese file
Compare the Chinese storage statement with the duration or date field next to it. Confirm that the limiting condition still applies to the intended period and that layout has not separated it from the relevant product wording.
Prepare the connected files
Supply the approved label and matching IFU passages. Ask the owner to clarify inconsistent duration or storage wording rather than deriving a new date.
Keep the term aligned across your files
Check intended use, warnings, document versions and approved terminology with the project team. Translation supports documentation; it does not establish product approval or regulatory acceptance.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
