APHIS ACE Message Set Reminders for Cargo Destined to Plant Inspection Stations

Plain-English explanation

CSMS 59090094 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on January 18, 2024. It carries the official CBP guidance brokers and importers must follow for the topic — "APHIS ACE Message Set Reminders for Cargo Destined to Plant Inspection Stations". CSMS messages are the operational layer between Commerce determinations and at-the-border collections: when Commerce publishes a new rate, scope ruling, or instruction, CBP turns it into a CSMS that ACE/ACS systems and brokers act on.

Full text as published by U.S. Customs and Border Protection

CSMS # 59090094 - APHIS ACE Message Set Reminders for Cargo Destined to Plant Inspection Stations U.S. Customs and Border Protection sent this bulletin at 01/18/2024 10:00 AM EST   Cargo Systems Messaging Service CSMS # 59090094 - APHIS ACE Message Set Reminders for Cargo Destined to Plant Inspection Stations The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) plant inspection stations (PIS) rolled out Entry Status Notifications (SO70) messages on August 7, 2023, to facilitate the inspection process and expedite goods to market. Since then, APHIS has noticed a few areas where the message sets could be improved and offers filers these reminders: If your commodity is destined to a Plant Inspection Station (PIS), the Government Agency Processing Code must be reported as A02 (APHIS Plant Inspection Station) to avoid delays. Use the correct AP0400 category code 403 (seeds for plant/for sowing) characteristic qualifier codes. The definitions of all qualifiers can be found in the ACE Appendix PGA . For seeds for sowing the three (3) characteristic qualifier codes are as follows: SSL – Small Seed Lot – 50 or fewer packets in a shipment and 10 or fewer grams per a packet SLL – Seed Large Lot – More than 50 packets in a shipment and/or more than 10 grams per a packet SEO – Seed Embedded/Obscured – Seed that is coated, pelleted, or embedded in tape, mats, or any substrate that obscures visibility. Review your documents. If a permit and/or a phytosanitary certificate was issued for the product you are importing, it must be reported in the PG13/14 LPCO section of the message set.

Frequently asked questions

What is CSMS 59090094?

CSMS 59090094 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "APHIS ACE Message Set Reminders for Cargo Destined to Plant Inspection Stations". CSMS bulletins are the operational instructions CBP issues to brokers, importers, and ACE filers covering rate changes, system updates, scope guidance, and other day-to-day customs-operations changes.

When was CSMS 59090094 published?

CBP published CSMS 59090094 on January 18, 2024. The bulletin's instructions are typically operative as of the publication date unless the body specifies a different effective date.

Is the CBP CSMS the legally binding instruction?

Yes — for at-the-border filing and entry collection. CSMS messages translate Commerce's Federal Register determinations into operational CBP instructions that ACE/ACS systems and brokers execute. The Federal Register notice is the underlying legal authority; the CSMS is the operational implementation. Both should be read together when reconciling a rate or scope change.
