APHIS Reminds Core Users to Expect Correction Requests through the Automated Commercial Environment for Cargo Moving to Plant Inspection Stations

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) plant inspection stations (PIS) remind filers that Entry Status Notifications (SO70) are sent through the Automated Commercial Environment (ACE) for cargo destined to a PIS. Filers will first receive an APHIS automated “may proceed” notification followed by either a request to correct or update their APHIS Core message sets as necessary. 

Genus and species information must be accurate in the Core Message Set to avoid delays. APHIS recommends reviewing the genus and species on phytosanitary certificates to ensure the spelling in the APHIS Core message set is correct. APHIS has posted an Agricultural Risk Management (ARM) system propagative name validation list to verify spelling. Software vendors may also download the list to use with the PG10 category AP0400 (propagative material) only. Filers must use PLANT UNIT (ACE CATAIR Appendix PGA code PTU) for PG26 unit of measure for plant shipments, and must use the KILOGRAM unit of measure (ACE CATAIR Appendix PGA code KG) for seed shipments.

Contact your local PIS for clarification regarding correction requests received from them. For help with the APHIS Core Message Set filing, visit our PIS, send an email to, or call our help desk at 1-833-481-2102.
