Testing timelines

Dangerous/hazardous goods

Packaging containing dangerous goods or hazardous materials cannot be tested. The only exceptions are packages that contain dry ice as the only dangerous goods component.

Instead, simulate hazardous materials using sand, water, or dummy products in the exact same configuration, same weight, and same packaging as the normal shipment. However, this test does not meet any regulatory compliance or certification requirements for hazardous materials.

We don’t provide packaging design services for dangerous goods, clinicals, or hazardous materials.

Getting the package back after the test

At your request, we’ll return your test package free of charge via FedEx Ground®, FedEx Express® (international customers only), or FedEx Freight® service. You can also request your packaging be returned using other FedEx® services, but the cost will be charged to your account number. We cannot return any freight package to a country or territory outside of North America free of charge. Special conditions apply to certain packages, such as alcohol or hazardous shipments.

How to prep a test package

Small parcel shipments

1. Mark the test package as “Test Package.”

2. Put the test package inside a sturdy outer shipping container.

3. Place material between the test package and the outer container. You can use foam, air-cellular cushioning, packing peanuts, or any other protective material to prevent damage to your test package during shipment.

4. Mark the outer container “Overpacked/Test Pkg. Inside.”

5. Attach a copy of the completed application to the outside of the outermost package using a shipping pouch or packing list envelope.

Freight shipments

1. Overwrap the test package using corrugated pads, angle boards, or stretch wrap to provide protection during shipment. 

2. Band palletized test packages onto an extra pallet and use an overwrap to help prevent damage during transit. 

3. Non-palletized shipments can be sent in an overbox or overpack, or on a pallet for safe shipment. Note on the application to remove the extra pallet before testing, if necessary. Also indicate which of the over-packing components to remove before freight testing.

4. Attach a copy of the completed application to the outside using a shipping pouch or packing list envelope.
