When Wisconsin plants and plant products are shipped to a different state, or to a foreign country, the destination location may require that the plants or plant products be inspected and certified that they are free of insects or diseases.
Plants and plant products include Christmas trees, landscape trees and shrubs, nursery stock, seed, fruits, grain and grain products, lumber, veneer, tissue culture plantlets, potatoes and seed potatoes. If you are unsure whether your product is included, check with us.
The certification paperwork that accompanies the plants or plant products may be a plant health certificate, a state phytosanitary certificate, a federal phytosanitary certificate or a processed products export certificate and are issued based off of inspections of the material being shipped.
