National Seed Health System (NSHS)
The NSHS was established by 7 CFR 353.9 . The NSHS specifies standards for laboratory seed health tests and seed crop field inspections used for issuing phytosanitary certificates that meet international regulations pertaining to seed exports from the United States.
State National Harmonization Program (SNHP)
This SNHP for seed potatoes specifies minimum phytosanitary standards to enhance uniformity and quality in seed potatoes shipped between states; enhance marketing of high quality commercial potatoes grown in the U.S.; and enhance international marketing of quality seed potatoes exported from the U.S. Requirements for participants include minimum standards set by State regulatory authorities for certification of seed potatoes to facilitate interstate shipment, export and cooperation in pest management.
