Storage conditions
The environmental limits a material must be held within for its documentation to remain valid.
What is a storage conditions?
Storage conditions are the environmental limits a material must be kept within for it to remain within specification — typically a temperature range, a humidity ceiling, protection from light, and a requirement that packaging stay sealed. They are set by the manufacturer and printed on the label and the specification. Storage conditions matter to a buyer of surplus material because the retest or expiry date on a batch is only valid if the material was actually held as required. A batch stored outside its stated range may be out of specification well before its nominal date, and conversely a correctly stored batch is generally exactly what its documentation says it is. This is why storage history and packaging integrity are asked about separately from the date: unopened, in original packaging, with seals intact and held as the label demands is a materially different proposition from a part-used container of the same batch.
How Surply uses it
Storage conditions and packaging state are part of the trust stack shown on every listing, alongside the batch and the documents. Unopened means still in original packaging with seals intact.
