APHIS Information

The Animal and Plant Health Inspection Service (APHIS) is a US governmental agency whose mission is to protect the health and value of American agriculture and natural resources. They regulate soils from certain zones within the United States as well as foreign soil and or plant sample materials.

If your county is regulated, soil MUST be packaged in two inner packages (such as a double bag) in addition to an outer shipping container.
