A phytosanitary certificate documents that a shipment meets the importing country's plant health requirements.
Detailed Definition
A phytosanitary certificate is an official document issued by the exporting country's national plant protection organization, or by officers it authorizes, stating that a consignment of plants or plant products was inspected or treated and meets the importing country's plant health requirements. Its format follows IPPC standard ISPM 12. In the United States, certificates are issued under the authority of USDA APHIS, often with state or county officials authorized to issue them. Whether one is needed depends on the commodity and the destination, not on the pallets carrying it.
Phytosanitary certificates versus the ISPM-15 mark
Wood pallets, crates and dunnage show compliance through the ISPM-15 mark applied to the wood itself. That mark is what inspectors look for on wood packaging, and a separate certificate is generally not needed for the packaging. A phytosanitary certificate covers the goods being shipped, such as fresh produce, grain, seeds, plants or some wood products, when the importing country regulates them. A shipment can need both: certified goods packed on ISPM-15 marked pallets.
Getting a certificate for a US export
Start by checking the destination country's import requirements for your commodity, which APHIS publishes for exporters. If a certificate is required, the exporter applies before shipment, and the goods may need inspection, testing or treatment first. Allow time for this in the shipping schedule, and make sure the details on the certificate match the commercial documents.
Common documentation mistakes
- Assuming ISPM-15 pallets need their own phytosanitary certificate.
- Commodity descriptions or quantities that do not match the invoice and packing list.
- Applying too late for required inspections or treatments.
- Shipping certified goods on unmarked wood packaging, which can still be refused.

Frequently Asked Questions
Do ISPM-15 pallets need a phytosanitary certificate?
Generally no. Wood packaging that meets ISPM-15 shows compliance through the mark on the wood, which includes the IPPC symbol, country code, producer or treatment provider number and treatment code. Importing countries check that mark. A phytosanitary certificate is about the goods being shipped and is required only when the destination regulates that commodity. Check the importing country's rules, because a few require extra documents in specific cases.
Who issues phytosanitary certificates in the United States?
They are issued under the authority of USDA APHIS, the US national plant protection organization. In practice, many certificates are signed by authorized state or county agricultural officials working under APHIS oversight, after any required inspection or treatment. Exporters apply through the APHIS process, and the certificate must match the shipment details. A freight forwarder or customs broker can help coordinate timing with the export booking.
