You will need this accreditation if you export plant products and intend to issue your own Plant Health Assurance Certificates (PHAC).
A PHAC is taken as evidence of compliance with quarantine requirements for interstate and intrastate trade. You can apply for this accreditation if you frequently move goods (plants, fruit or vegetables) interstate or between quarantine zones and require a PHAC.
The Interstate Certification Assurance (ICA) scheme is a national scheme based upon quality assurance principles, that accredits a business (e.g. grower) to operate an ICA Arrangement and issue their own PHAC's for exporting produce to other States. PHAC's issued by ICA Businesses have the same legal effect as Plant Health Certificates (PHC's) issued by the Agency.
