How to obtain a DG packaging certificate
The manufacturer applies to their local CIQ office (now part of China Customs) with samples of the DG packaging. CIQ conducts physical tests: drop test, leakproofness test, hydraulic pressure test, stacking test. Testing takes 5-10 working days. Once the packaging passes, CIQ issues the certificate. The certificate is specific to a packaging type, manufacturer, and DG class, if you change packaging or DG class, a new certificate is required.
Practical Example
A Shandong chemical manufacturer needs to export Class 8 corrosive liquid (sulfuric acid) in 25L plastic jerrycans. Before shipment, the jerrycan manufacturer applies to Qingdao CIQ with jerrycan samples for UN packaging testing. CIQ tests include drop test (1.8m for PG II), leakproofness test, and stacking test. After passing (7 working days), CIQ issues the DG Packaging Certificate specifying: packaging type (1H1 plastic jerrycan), UN marking, DG class compatibility, and validity period. Great Hensen then uses this certificate to submit the Maritime DG Declaration and book the shipment.
