A stipulation in a credit that "Freight Forwarder's non-negotiable sea waybill is not acceptable" or "House non-negotiable sea waybill is not acceptable" or words of similar effect has no meaning in the context of the title, format, content or signing of a non-negotiable sea waybill unless the credit provides specific requirements detailing how the non-negotiable sea waybill is to be issued and signed. In the absence of these requirements, such a stipulation is to be disregarded, and the non-negotiable sea waybill presented is to be examined according to the requirements of UCP 600 article 21.
