What we accept
(case-by-case)
Our bank acceptance policy
We accept instruments issued or confirmed by the current Top-30 global banks by total assets (reviewed twice yearly). Issuer acceptance always remains subject to sanctions/AML status and Mezzarion discretion.

-
SWIFT authenticity: issued via authenticated SWIFT (MT700/701 for L/C; MT760 for SBLC/guarantee).
We do not accept screenshots, PDFs, or “tear sheets” as issuance. -
Bank verification: issuing (and, if any, confirming) bank on our acceptable list; independent call-back via the bank’s published switchboard for high-value cases.
-
No soft clauses: no conditions dependent on buyer discretion, unprovable events, or “subject to acceptance by…”.
-
Reasonable presentation: typical 21 days after shipment, with a clear place of expiry.
-
Costs allocation: clearly stated (confirmation, discrepancy, courier, etc.).
-
Transferability/assignment: expressly stated if required.

Governing law/forum (if stated) should not conflict with URDG mechanics.
