It is up to the shipper of the paint cans to use inner packaging that is equal or stronger in performance than the inner packaging used during the UN testing per 49 CFR 178.601(g)(1).

If shipping by air it is a little different, as the inner packaging “must be capable” of withstanding a hydrostatic pressure differential of 95 kPa per 173.27(c)(2).
