As defined by the DOT in 49 CFR 178.8, Composite Packaging means a package consisting of an outer package and an inner receptacle, so constructed that the inner receptacle and the outer packaging form an integral packaging. Once assembled it remains thereafter an integrated single unit; it is filled, stored, shipped and emptied as such. For those units that offer a UN certification, the combining of component items to yield the single package, can introduce items manufactured and marked with varying dates. However, the final Combination Package must be dated and marked on the basis of the unit assembly, not the individual manufactured elements. The assembly date also must be reflected in the UN Certification documents.
