If you are a producer who frequently moves goods interstate or between quarantine zones, your business may be accredited by a state or territory plant quarantine authority to issue Plant Health Assurance Certificates (PHAC's) for your produce through the Interstate Certification Assurance (ICA) Scheme.
Once a business is accredited, it assumes responsibility for specified treatments, inspections or other processes, and can issue PHAC's for its own produce.
Quarantine authorities carry out audits on a business to ensure it continues to meet its obligations and for it to maintain accreditation.
Treatments can include dipping, spraying, heat or cold treatment and inspections. Each type of produce may require a number of these procedures, depending on their origin and destination.
Quarantine requirements may change as new pests, diseases and weeds are detected, so accredited businesses must ensure they stay up-to-date by contacting their local ICA supervisor at the time of consignment.
