Haku batch code and freshness guide
Use this Haku page to decode batch or lot codes and estimate production timing before opening or repurchasing.
When multiple years are possible, combine decoding output with purchase timing and packaging generation.
When Haku print quality is weak, a brighter angle and uppercase retry usually improves recognition.
- Enter one complete code string from a single package location instead of combining fragments.
- Short Haku codes are easy to mistype, so compare the box print and bottle print before submitting.
- Decoding is an estimate; combine it with PAO symbols and open-date tracking for safer decisions.
- If possible, decode a sample lot before bulk buying to compare freshness across sellers.
