Phytosanitary Certificate Issuance and Tracking System
Animal and Plant Health Inspection Service (APHIS) and Plant Protection and Quarantine (PPQ) are responsible for safeguarding agriculture and natural resources from the risks associated with the entry, establishment, or spread of animal and plant pests and noxious weeds. The Phytosanitary Certificate Issuance and Tracking (PCIT) system tracks the inspection of agricultural products and certifies compliance with plant health standards of importing countries.
