Trade assurance on Alibaba expires 45 days approximately dating from the date of shipment. I believe that this has changed now but then it was in effect.
For some reason Chengli shipped the truck via such a route that the vehicle changed ships at some point and only arrived in Chile after about 60 days.
When I received it, the trade assurance had already expired. It is possible that it had not actually expired but the contact person told me that it had expired.
