A participant (such as a carrier/warehouse operator) may utilize the query function to determine the status of both pre and post arrival release transactions. To send a CUSREP status query, the participant includes the following in their EDI message:
· cargo control number in uppercase characters only or
transaction number
· office code
· query code ("998" signifies status query message)

If a recommendation record is on file in the system with either a "to be released" or "to be referred for examination" status, a CUSRES "Declaration accepted - awaiting goods arrival" message would be provided to the participant. If the release transaction is in the system and awaiting processing by a Border Services Officer, then the system will transmit a response message with a status of “Transaction Awaiting Processing”. Query messages with invalid data would be responded to with an error message.

If a release decision is on file in the system, a CUSRES message with a status of either “Goods released”; “Goods required for examination, referred” or “Goods may move under Customs transfer - detain at destination (CFIA)” will be sent to the originator.
