What action must be taken regarding the DEA export permit document by the shipper?

The requirement for the shipper to enter details such as the carrier name on the DEA export permit document is essential for ensuring compliance with regulations governing the export of controlled substances. This documentation serves as a formal acknowledgment that the shipper is authorized to export certain goods, particularly those regulated by the Drug Enforcement Administration.

Entering the carrier name is important because it ties the shipment to a specific transporter, which helps maintain a clear chain of custody for the controlled substances being exported. This transparency is vital for adherence to international trade laws and the regulations set by the DEA, reinforcing accountability throughout the shipping process.

In contrast, the other options involve actions or requirements that are not applicable to the handling of the DEA export permit. For instance, stamping the document by the local government is not a mandated practice in the context of DEA permits, and keeping it confidential does not align with the document's purpose, which includes necessary disclosures for legal and regulatory compliance. Lastly, stating that the DEA export permit is not required is incorrect, as the permit is a critical document for exporting controlled substances.
