USDA APHIS Inspected Facilities Authorized to Receive Soil

This is the updated list of facilities inspected by USDA-APHIS to receive foreign and interstate (domestic) soil samples. This list supersedes all previous lists. Facilities inspected to receive foreign soil samples must obtain a soil permit and sign a compliance agreement. The compliance agreement also authorizes the facility to receive domestic shipments. Facilities inspected to receive foreign soil samples have the permit expiration date in parenthesis following the name and address. Facilities shown without a date or with an asterisk are authorized to receive domestic soil only. Soil received by an inspected facility may not be re-shipped to any other facility unless the destination facility is shown in this list as eligible to receive that type of soil.
