Can You Use Sugar After the Best-Before Date?
Written by Jordan Morley · Reviewed against FSA date labelling guidance · Last updated 28 October 2026
Yes. Sugar has a best-before date, which is about quality rather than safety, so it is usually fine to use after the date. Check that it looks and smells normal.
Why it's usually fine past the date
A best-before date is the maker's estimate of how long sugar stays at its best. After it, it doesn't, apart from clumping if it gets damp; it doesn't suddenly become unsafe. The FSA says food is generally safe to eat after its best-before date, and using your own judgement also cuts food waste. Throw it away if you see: insects or visible contamination.

Common questions
Does sugar ever expire?
Granulated sugar lasts indefinitely in the pantry (USDA FoodKeeper), so the date is only a guideline. If it clumps from damp, break it up; it is still fine.
How can I tell if sugar has gone off?
Look for insects or visible contamination. If none of those apply and it looks, smells and tastes normal, it is fine.
What actually changes after the best-before date?
It doesn't, apart from clumping if it gets damp. That's a drop in quality, not a safety problem (FSA).
What is the difference between use-by and best-before?
Use-by is about safety: do not eat after it. Best-before is about quality: the food is often fine after it, just past its best. Check which one is on your label.
