A.
Composite Packagings are packagings consisting of an outer packaging 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, transported and emptied as such. Due to the nature of being an integrated packaging, it is regarded as a type of single packaging in the DGR. The inner receptacle is not independent to the outer casing. It is not like the inner packaging of a combination packaging, therefore the inner is called as inner receptacle.

The UN specification code starts with the UN Mar ; followed by, for example 6HA1/Y1.4/150/11/NL/VL824. 6 stands for Composite Packaging; H is the plastic inner receptacle; A is the outside steel outer packaging; 1 means that the outside packaging is a drum; Y1.4 is the PG and the relative density; 150 is the test pressure expressed in kPa; 11 means Year 2011; NL is the country of manufacture per VRI code; and VL824 is the manufacturer code number. Please refer to Table 5.0.C.; 5.0.2.12.1 Note; 6.0.3.2; 6.2.17; and Appendix A.
