Hi Poy,
Last shipment, we were charged by LC issuing bank for this document with:
Shipping company certifying ….. under institute classification clause Nippon Kaiji Yokai, but without grade 100 A1.
“The vessel has been survey by the Japanese Classification society and classed as far as I'm concerned equivalent to the Lloyds Classification” This is the reply from our insurance company for last shipment.
So, it seems your agent just missing to mention 100 A1 in the certificate.
To my experience, when customers asking for such certificate, it used to mention classification equivalent to Lloyds Grade 100 A1.
Hope this would be clear to you.
Regards
Jola
