What are the responsibilities of the exporters (shipper/agent)?
1. Apply, in writing, for the inspection, sampling, testing, and certification of commodities offered for export. Certificates can be issued at the point of origin, at a port where the shipment will transit, or at the actual port of export. PPQ Form 572, Application for Inspection and Certification of Domestic Plants and Plant Products for Export, can be requested from the nearest ACO office or download form by clicking here.
2. Contact an Accredited Certification Official (ACO) far enough in advance of the shipping or loading dates to allow the ACO to determine the phytosanitary import requirements and conduct required sampling, inspecting, testing, etc. in advance of the shipping or loading dates and specified time limits. Refer to Exporter or Shipper Responsiblities Related to the Export Certification of Plants and Plant Products.
Exporters must be aware of and plan for any time limit restrictions a foreign country may specify for the period between date of inspection or date of certificate issuance and shipping date. If a time limit is not specified by a country the policy on time limits for inspections is not more than 30 days before export.
3. Provide all necessary documentation, including, import permits, bills of lading, manifests, shipping invoices, foreign phytosanitary certificates, and inspection certificates. It is the exporter’s responsibility to provide official documents stating import requirements if they differ from those that USDA-APHIS-PPQ has. Official documents may be an import permit, special authorization, or recent correspondence from the National Plant Protection Organization (NPPO) of the foreign country.
Exporters are responsible for ensuring official documents are translated into English; USDA-APHIS-PPQ does not provide translation services. Bilingual information is acceptable as long as one of the languages is English.
4. Make the commodity available for inspection, sampling, testing, etc. Shipments cannot be inspected on board aircraft or ships. Additionally, commodities which are loaded into maritime containers in bulk form can not be inspected once the container has been loaded. It is the exporter’s responsibility to ensure that they make arrangements to have the consignment sampled and/or inspected prior to loading containers.
Ensure the commodity is accessible to the ACO s to verify, sample and inspect the consignment. In addition, other shipping documents should be marked or stamped to prevent the shipment from being loaded before the inspection is conducted.
5. Providing labor to open and close packages for inspection and for providing adequate facilities to perform the inspection. Such facilities include supplies, equipment, and proper lighting required for an efficient inspection before certification.
6. Provide for any required treatments, reconditioning, or other actions to meet the import requirements of the foreign country.
7. Export only those plants or plant products that have been properly inspected and certified under a Federal plant export certificate.
8. Safeguard the certified shipment from infestation between the date the shipment was sampled and the actual shipping date, and ensure that the certified shipment departs within the time limits specified by the importing country.
9. Comply with U.S. export control regulations. The Federal government controls the exportation of U.S. goods to all foreign countries. The Department of Commerce is the authority for licensing most items for export. Other Federal agencies such as the Agricultural Marketing Service and the Federal Grain Inspection Service handle the certification for specific products.
