Most major ports have PPQ operated facilities where soil can be treated under prescribed treatment schedules. These treatments require dry heat at 250 F. for at least two hours or steam heat at the same temperature for 30 minutes with 15" pressure.
Importers are cautioned that P525 Soil Permit does not authorize hand carried shipments to the port of entry, all foreign soil packages must be shipped via bonded carrier. As a result, handling and forwarding arrangements may be necessary to ensure that the shipment is forwarded to the destination after it has been treated and released by PPQ. The importer or permittee is responsible for all arrangements and the costs associated with handling and forwarding.
Mail and cargo shipments must arrive with postage or freight paid for delivery to the destination. Applicants indicating a need to ship by mail or freight are provided with labels (PPQ Form 508) which should be affixed to the outside of shipping packages. These labels identify the package as regulated material subject to special handling. A copy of the permit should also accompany each shipment.
All soil shipments which are authorized to be treated at the Plant Inspection Stations (PIS), must be shipped in sturdy, leakproof cloth bags within a sturdy leak-proof container, which can be heat treated without removing the soil. Notes, labels, or reference materials related to the shipment should be separate (or steam heat and dry heat resistant) to be sure that important information is not lost or destroyed during treatment. Permittees are encouraged to consult PPQ at the port of entry before shipping soil in other than a sturdy cloth bag.
Any shipment which is not authorized under permit will be held by PPQ at the PIS pending the issuance of a formal written permit from the Permit Unit. Any shipment which is not ultimately authorized or is not in compliance with permit requirements, must be destroyed or re-exported at the importer's expense.
