APHIS Announces Updates to Plant Inspection Station Message Set Filings and Deployment Dates

Cargo Systems Messaging Service CSMS # 69379587 - APHIS Announces Updates to Plant Inspection Station Message Set Filings and Deployment Dates The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) updated the APHIS Core Message Implementation Guide and Supplemental Trade Guide for filings of imports destined for Plant Inspection Stations (PIS). They can be found in the Draft Chapters: Future Capabilities https://www.cbp.gov/trade/automated/catair . These updates are intended to improve data accuracy, streamline routing, and support timely clearance of regulated plant commodities. 1. Updates to Plants for Planting – Category Code 406 (Tissue Culture) APHIS has revised the Plants for Planting section of the Implementation Guide as follows: Category Code 406 is now titled Tissue Culture. A new definition has been added. Filers must now report the Growing Media (A43) qualifier when using Category 406. o Acceptable values: AGAR or EXAR Filers should utilize (A41) physical state where applicable. o Acceptable values: WIRT or WORT For full definitions, filers should consult the updated Appendix PGA, and for technical/business rules, the APHIS Core Message Set Implementation Guide and Supplemental Trade Guide. 2. Update to PG30 Record – Laboratory/Testing Status “I” APHIS is updating the PG30 record to allow the use of “I” as a valid inspection laboratory/testing status. This indicator is required only for products proceeding to a PIS. Using “I” helps expedite automated routing of message set data to the correct PIS location for review and clearance. Please see link of PIS Locations and acceptable port codes for routing in the APHIS Core Trade Supplemental Guide. NOTE: Filers must continue to report the Port of Arrival (“A”), even if it differs from the anticipated inspection location. The deployment dates for these updates are: ACE CERTIFICATION environment (CERT) – July 27, 2026 ACE PRODUCTION environment (PROD) – August 27, 2026 Contact Information For questions or technical filing assistance, please contact the APHIS ACE ITDS Help Desk at ace.itds@usda.gov .
