| 149 | Labelling practice varies from a printed label naming compound, nominal mass, lot and storage recommendation, to a hand-written designation, to no label at all. Unlabelled vials are supplied deliberately in some channels, on the reasoning that the label is what makes a parcel identifiable; the consequence is that the material's identity depends entirely on packaging that is discarded, and that a [[certificate of analysis]] cannot be tied to a specific container.{{r|usp1207}} | 149 | Labelling practice varies from a printed label naming compound, nominal mass, lot and storage recommendation, to a hand-written designation, to no label at all.

| + | 151 | 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}} | |
