Dangerous Goods Packaging Certificate
What Is a Dangerous Goods Packaging Certificate?
A Dangerous Goods Packaging Certificate is the common export name for China's Outbound Dangerous Goods Transport Packaging Use Appraisal Result Form. China Customs issues it after an appraisal of the packaging used for a regulated dangerous-goods shipment.
In Chinese trade practice, the certificate is often called weibao zheng. It is a China-specific customs result form. It is not a general certificate issued by a packaging supplier.
The form records the result of the packaging use appraisal and identifies the applicant, goods, packaging, and transport conditions covered. It does not replace the packaging performance test result, transport classification report, safety data sheet, or dangerous-goods declaration. Each document answers a different question.
The appraisal is tied to the goods and packaging presented for inspection. A certificate for one product, packaging configuration, or transport mode does not automatically cover a different shipment.
Packaging Performance Test vs Use Appraisal
For listed export dangerous chemicals, China Customs applies two separate packaging checks. The packaging performance inspection examines the packaging itself. The use appraisal examines how that packaging is used for the actual goods and shipment.
| Document | Question it answers | What to check |
|---|---|---|
| Packaging performance test result | Does the packaging design, type, specification, or production batch meet the applicable standard? | This result concerns the packaging before it is used for the shipment. |
| Dangerous Goods Packaging Certificate | Has the packaging for the actual goods been used and assembled in line with the applicable export rules? | The appraisal is shipment-specific and records the result for the packaging configuration presented. |
The performance result does not automatically establish that a particular shipment has been packed correctly. The use appraisal checks the connection between the inspected packaging and the goods, packing method, and intended transport mode.
For goods that fall within China's packaging inspection rules, one document does not replace the other. Keep both with the export file and make sure their product and packaging details agree.
When Is the Certificate Required?
In China, the certificate is required when an export falls within customs packaging inspection rules. The main points are:
| Review point | Why it matters |
|---|---|
| Listed export dangerous chemicals | These goods fall within customs packaging inspection rules. Customs carries out the relevant packaging inspection and use appraisal. |
| Other regulated dangerous goods | The requirement depends on the transport mode, international dangerous-goods rules, carrier, route, local customs practice and any applicable exemption. Sea, air, road and rail rules differ, and one mode does not automatically cover another. |
| Bulk or exempt shipments | Bulk shipments and goods exempt from packaging requirements under the applicable international rules may follow a different document path. Confirm the exemption before export. |
| Changes to the shipment | If the packaging type, size, closure, containment method, goods or transport mode changes, ask the local customs authority whether a new performance inspection or use appraisal is required. |
