Let?fs say he has a license to produce UN pckagings in Country A.
Now he wants to start production in Country B. The license to produce and the testing of a batch of production are two Sep rate matters. Depending on the laws of Country B, he May be able to start production in Country B with his Country A license, however the new batch of packagings which he has produced must undergo a test to be certified as conforming to UN quality.
He will either have to send samples from that batch to the testing facility in Country A, or have a testing facility in Country B perform the required test to certify that the packaging can carry the UN specification Mar ing. Each batch needs to be tested.
