Accreditation Systems and Programs

Accreditation Systems and Programs

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.


Trade of Greenhouse-grown plants between Canada and the United States
The United States has an agreement with Canada to facilitate trade in greenhouse-grown plants between the two countries. This agreement, known as the U.S.-Canada Greenhouse Certification Program (GCP), has been in place since 1996.  The current agreement and requirements for shipping greenhouse-grown plants from the United States to Canada are provided below.

APHIS and the Canadian Food Inspection Agency (CFIA) are revising the GCP to reflect current trade in greenhouse grown plants and to improve oversight to minimize phytosanitary risk associated with movement of plants under this program.  APHIS is requesting comments on the revised program.  A link to the consultation documents and information on how to provide comments is provided below. 

Plants in Growing Media    - Phalaenopsis 
Phalaenopsis spp. , commonly known as moth orchids, are grown in pots primarily for the interior design market. Moth orchids are typically mass produced and sold at wholesale to general merchandise retailers and specialty outlets where they are purchased by consumers. Phalaenopsis spp. and other orchids are imported into the U.S. as bare rooted plants, or growing on tree fern or in coconut husk or fiber ( 7 CFR § 319.37-8(d)) and are admissible subject to inspection findings at USDA plant inspection stations at certain U.S. ports of entry. Many U.S. potted orchid growers start out with imported plants; they purchase the bare rooted imports, grow them, and then pot them for sale. Phalaenopsis production facilities in Taiwan on the list below may export plants in approved growing medium to the United States so long as the plants meet the requirements in the Code of Federal Regulations 7 CFR § 319.37-8. Shipments must be accompanied by a phytosanitary certificate issued by the plant protection service of Taiwan.
