That is what I recall, from many years ago. You can have a dozen plants imported & skip the APHIS Inspection process. The Phytosanitary Permit, you Paid for, to the sender, is already the proof that the plants were -already Inspected- & determined to be healthy, & basically free of disease &/or pests..
But, a note of Caution; If there is any potting soil , or dirt on the roots & your parcel of a dozen rhizomes is opened for "general inspection" by Dept. of Agriculture, they can destroy it, right then & there if the rhizome & roots aren't washed clean & completely free of any soils/dirt or potting mix !
