New cargo release error 336 requires invoice or merchandise description on type 13 entries
CBP title: Updated Cargo Release Condition Codes Document Posted to CBP.gov
What did CBP announce?
CBP posted an updated Cargo Release Condition Codes document to cbp.gov. It adds error code 336, "INVOICE/MERCH DESC REQUIRED FOR ET13," a validation rule for the Commercial Invoice Description in the SE40 record. CBP will deploy the rule to the ACE Cargo Release Production environment on October 15, 2026.
What is Allied's position?
From October 15, 2026, ACE will reject a type 13 mail entry that lacks a commercial invoice description in the SE40 record. We need a clear invoice or merchandise description for every mail shipment we enter as type 13. Clients and postal partners should make sure each shipment comes with an invoice that describes the goods.
