What does the "chain of custody" concept refer to in relation to phytosanitary certification?

The concept of "chain of custody" in relation to phytosanitary certification refers specifically to the process of tracking and verifying the handling of plants and plant products throughout all stages until they reach export. This process ensures that all necessary phytosanitary measures are followed and documented, providing accountability and traceability from the point of origin to the point of export.

By maintaining an accurate chain of custody, authorities can confirm that plants and plant products have been handled in compliance with national and international regulations. This is crucial for minimizing the risk of introducing pests and diseases to new regions, and it assists in maintaining the integrity and safety of agricultural exports.

Other options address related aspects of the export process, such as inspections during transportation, agreements between parties, or required documentation for exports, but they do not encompass the comprehensive nature of tracking and verifying the entire journey of the plant materials, which is the essence of the chain of custody concept.
