A phytosanitary certificate is a government-issued document confirming that a shipment of plants or plant products has been inspected and meets the importing country’s pest and disease requirements. In the United States, USDA’s Animal and Plant Health Inspection Service (APHIS) inspects the goods and issues the certificate, charging $106 for a commercial shipment or $61 for a non-commercial one. You need one whenever the destination country requires it for the commodity you’re shipping, and arriving at the border without it can mean your goods are refused, destroyed, or returned at your expense.
The purpose is straightforward: stop invasive insects, fungal diseases, and noxious weeds from crossing borders inside plant shipments. The International Plant Protection Convention (IPPC) sets the global framework through its International Standards for Phytosanitary Measures, so most trading countries work from a common playbook.1International Plant Protection Convention. Adopted Standards (ISPMs) Only a technically qualified officer authorized by a country’s national plant protection organization can sign one.2International Plant Protection Convention (IPPC). ISPM 12 – Phytosanitary Certificates
When You Need One
Importing countries can require a certificate for any “regulated article.” That usually means plants and plant products, but it can extend to empty containers, vehicles, or other items when there is a documented pest risk.2International Plant Protection Convention (IPPC). ISPM 12 – Phytosanitary Certificates Common commodities that trigger the requirement include:
- Fresh fruits and vegetables
- Seeds
- Cut flowers
- Timber and lumber
- Growing media
Rules differ by country and by commodity. Japan may demand a specific test for a citrus variety that Canada waves through with a standard inspection. Before you ship, check the destination country’s requirements. APHIS maintains the Phytosanitary Export Database (PExD), which lists import requirements by country and commodity, including required treatments, additional declarations, and permitted points of entry.3USDA: PCIT Online Help.

What a Certificate Cannot Cover
Some plant materials are prohibited outright, and no certificate will move them. Federal noxious weeds and parasitic plants, including their seeds, cannot be imported into the United States from any country. They may only enter for research in an APHIS-approved containment facility under a separate permit.4Animal and Plant Health Inspection Service (APHIS). Plants With Special Requirements and Prohibited Plants
The Small Lots of Seed Exemption
If you are importing a small quantity of seeds into the United States, you may not need a phytosanitary certificate at all. Under USDA regulations, small seed lots can enter with only a written permit (PPQ Form 587) when the shipment meets every condition below:5eCFR. 7 CFR 319.37-6 – Phytosanitary Certificates
- No more than 50 seeds or 10 grams of one taxon per packet, and no more than 50 packets per shipment
- Each packet labeled with the seller’s name, scientific plant name, and country of origin
- Seeds sealed against spillage and free of soil, non-seed plant material, pesticides, and living organisms
- Seeds not from federal noxious weeds, not from parasitic plants, not pelleted or coated, and not on the “Not Authorized Pending Pest Risk Analysis” list
Tomato and pepper seeds are excluded from the exemption and still require a phytosanitary certificate even in small quantities.6Animal and Plant Health Inspection Service (APHIS). Seeds With Special Requirements and Prohibited Seeds
Wood Packaging Uses a Different Rule
Wooden pallets, crates, and dunnage do not travel on a phytosanitary certificate. They fall under ISPM 15, which requires debarking plus heat treatment or fumigation, followed by a stamp bearing the IPPC logo, a two-letter country code, a facility number, and the treatment code (HT for heat, MB for methyl bromide). Non-compliant wood packaging will not be allowed into the country, so confirm the treatment mark with your supplier before the shipment leaves the origin port.7Animal and Plant Health Inspection Service. Import ISPM 15-Compliant Wood Packaging Material Into the United States
Re-Export Certificates
When plants or plant products enter the United States and are then shipped onward to another country, APHIS issues a phytosanitary certificate for re-export rather than a standard certificate. It confirms the goods arrived with a valid original certificate, still conform to the final destination’s requirements, and have not been exposed to pest risk in storage. The original phytosanitary certificate, or a certified copy, must travel with the re-export certificate.8International Plant Protection Convention (IPPC). ISPM No. 12 Guidelines for Phytosanitary Certificates If the goods were repackaged, split, or combined in the United States, that gets noted on the certificate.
One caveat: if the consignment was exposed to contamination, lost its identity, or was processed in a way that changed its nature, the United States issues a standard phytosanitary certificate instead, because it is effectively certifying a new product.
How to Apply in the United States
U.S. exporters apply through the Phytosanitary Certificate Issuance and Tracking (PCIT) system, APHIS’s online platform. You’ll need a USDA eAuthentication account to log in.9Animal and Plant Health Inspection Service. PCIT APHIS suggests contacting your local phytosanitary office before your first application.
The formal application is PPQ Form 572, filed at the office of inspection at your port of certification. One application per consignment, one certificate per consignment.10eCFR. 7 CFR Part 353 – Export Certification The application should include exporter and importer names and addresses, the commodity’s botanical name and quantity, the country of origin and final destination, any treatment details (chemicals, temperature, duration, concentration), and any import permit numbers or additional declarations the destination requires.11USDA Animal and Plant Health Inspection Service. PPQ 577 Phytosanitary Certificate (Sample Copy)
Once filed, an Authorized Certification Official inspects the consignment. ACOs can be federal PPQ officers or trained employees of state plant protection agencies.10eCFR. 7 CFR Part 353 – Export Certification File early. Inspection scheduling depends on local workload and how complex the commodity is.
Fees
For certificates issued directly by PPQ officers:12Animal and Plant Health Inspection Service. User Fees for Export Certification of Plants and Plant Products
- Commercial shipments (value $1,250 or more): $106
- Non-commercial shipments (value under $1,250): $61
- First replacement certificate: $15
- Subsequent replacements: full fee ($106 or $61)
Certificates issued by state or county ACOs carry a $6 PPQ administrative fee, plus whatever the state or county charges. Overtime inspections add overtime fees on top. No fee applies when a certificate has to be replaced because of an ACO’s own error.
Timing and Validity
Two clocks apply, and confusing them causes real problems.
The first is the gap between inspection and issuance. USDA policy requires the certificate to be issued within 30 days of the physical inspection. A recent amendment allows issuance up to 60 days after inspection if the shipment left the United States within 30 days, with transportation documents to prove it. Miss the window and the goods must be re-inspected.
The second clock is the certificate’s period of validity after issuance, which the importing country sets. ISPM 12 acknowledges that importing countries may specify how long a certificate stays valid and how quickly the shipment must be dispatched once it’s issued.13International Plant Protection Convention (IPPC). ISPM No. 12 Guidelines for Phytosanitary Certificates – Section: 1.5 Requirements Made by Importing Countries An expired certificate is grounds for rejection at the destination. Check the destination country’s specific limits before you book transport.
Electronic Certificates (ePhyto)
Paper certificates are gradually being replaced by ePhytos, which carry the same information in a standardized electronic format sent directly between national plant protection organizations through the IPPC’s central Hub.14International Plant Protection Convention. IPPC ePhyto Solution The practical value for you is speed: the ePhyto can reach the importing country before the shipment does, which cuts clearance delays. Countries without their own electronic system can use the IPPC’s Generic ePhyto National System (GeNS).
Penalties for Shipping Without One
Skipping certification is not just a paperwork problem.
At the border, U.S. Customs and Border Protection confiscates undeclared or prohibited agricultural products. Civil penalties for a first-time non-commercial offense can reach $1,000 per violation, with much higher rates for commercial goods, and the same rules apply to items sent through international mail.15U.S. Customs and Border Protection. Bringing Agricultural Products Into the United States
The heavier penalties come from the Plant Protection Act. The statute caps civil penalties at $50,000 per violation for an individual and $250,000 for a business entity, with a $1,000,000 ceiling on all violations in a single proceeding that include a willful violation.16Office of the Law Revision Counsel. 7 USC 7734 – Penalties for Violation Those base figures are adjusted for inflation each year. In 2025, the adjusted maximums are $90,708 per individual violation and $453,537 per violation for other persons.17Federal Register. Civil Monetary Penalty Inflation Adjustments for 2025 Where forged or unauthorized certificates are involved, an alternative penalty of twice the gross gain or gross loss can apply.
Criminal exposure attaches to knowing violations. Forging, counterfeiting, or altering a certificate carries fines under Title 18 and up to one year in prison. Knowingly importing or exporting regulated articles for distribution or sale in violation of the Act carries up to five years, and a second conviction raises the maximum to ten.16Office of the Law Revision Counsel. 7 USC 7734 – Penalties for Violation
There is a narrow break for first-time individual violators who are not moving goods for monetary gain: the cap is $1,813 (inflation-adjusted). Any commercial motive removes it.17Federal Register. Civil Monetary Penalty Inflation Adjustments for 2025
