There is no condition scale for food. There is a label, and the listing is a faithful copy of it plus the state of the packaging.
What must be in every listing
Sealed or opened. Opened food is not something most buyers want; say it plainly if it is. The date, and which kind — best-before or use-by. Ingredients and allergens, written out, not only shown in a photograph. A buyer searching for an allergen needs the words. Weight or volume. Batch or lot code, where there is one. Storage — what it needs, and what happens if it does not get it.
Packaging condition
Dented tins, crushed cartons, a cracked seal, a label that has come away. All worth stating, and a damaged seal means the item should not be sold at all.
Homemade and unpackaged
If you made it, the listing has to carry what a label would: ingredients, allergens, the date it was made, how long it keeps and how to store it. And the licence question from the selling guide comes first.
Words to avoid
Anything suggesting a health benefit, a cure or a treatment. That moves the product into a category needing a licence the seller must hold, and it is a claim nobody can support. Prohibited items.
The sentence worth copying
"Sealed, best before 03/2027, 400g, contains milk and wheat, store cool and dry. Carton has a small dent on one corner — shown."
Everything a buyer needs, in one line, with nothing to discover on arrival.
Questions people ask
Do I have to list allergens if they are on the pack?
Yes, in words. A photograph is not searchable and not everyone can read it.
Is a dented tin sellable?
If the seal is intact and the dent is shown. If the seal is compromised, no.
What if I do not know how long something keeps?
Then you cannot describe it safely, and it should not be listed.
