| 153 | Because the vial is unremarkable, it carries almost no evidential weight. A professionally printed label, a coloured flip-off button and a crimped seal are all obtainable independently of any manufacturing capability, so their presence does not distinguish material from a competent supplier from material repackaged elsewhere. The examination indicators that do carry some weight are those that are hard to reproduce consistently: agreement between the lot number on the vial and on the certificate, a crimp with no evidence of recapping, a cake consistent in appearance with the stated mass, and headspace behaviour on first penetration consistent with the vial having been sealed under vacuum.{{r|usp1207,ppvial}} | 153 | Because the vial is unremarkable, it carries almost no evidential weight.

| + | 155 | Community-collated observations of vial and closure characteristics across suppliers exist and are useful for identifying gross inconsistencies within a single supplier's output over time. They are photographic and self-reported, without controlled lighting, measurement or chain of custody, and they cannot establish provenance. Their principal documented value has been in flagging discrepancies that prompted analytical testing rather than in substituting for it.{{r|ppvial}} | |
