Mail. Samples of unroasted coffee that are transiting Hawaii or Puerto Rico en route to other destinations and that are packaged to prevent the escape of any plant pests may proceed without action by an inspector. Packaging that would prevent the escape of plant pests includes, but is not limited to, sealed cartons, airtight containers, or vacuum packaging. Samples of unroasted coffee received by mail but not packaged in this manner are subject to inspection and safeguard by an inspector. These samples must be returned to origin or forwarded to a destination outside Hawaii or Puerto Rico in a time specified by an inspector and in packaging that will prevent the escape of any plant pests. If this action is not possible, the samples must be destroyed.

Cargo. Samples of unroasted coffee that are transiting Hawaii or Puerto Rico as cargo and that remain on the carrier may proceed to a destination outside Hawaii or Puerto Rico without action by an inspector. Samples may be transshipped in Puerto Rico or Hawaii only after an inspector determines that they are packaged to prevent the escape of any plant pests. Samples that are not packaged in this manner must be rewrapped or packaged in a manner prescribed by an inspector to prevent the escape of plant pests before the transshipment will be allowed.

Other mail, cargo, and baggage shipments of articles covered by § 319.73-2 arriving in Puerto Rico or Hawaii may not be unloaded or transshipped in Puerto Rico or Hawaii and are subject to inspection and other applicable requirements of the Plant Safeguard Regulations (part 352 of this chapter).
