products that are exempt from inspection at the time of export need to be inspected according to the specific commodity name and commodity code when they are returned for import. This is because some commodity names do not need to be inspected at the time of export, such as wires, cables and connecting wires, which need to be inspected at the time of import.
In addition, if the products are returned, whether commodity inspection is required or not, you need to apply to the local inspection and quarantine agency for a certificate of intermediate inspection, which is a necessary condition for returning.
