Could you please request your team to directly request the explanation from NHK for this issue? As the time of receipt 73, It shows 1 month to report discrepancy but the information that I got from them, they have their own stock before CMMS and FIFO to use the stock (use their stock first).
You may be able to claim them but I am too shamed to claim them ,they are supporting AAT, Assy and support many request from AAT during new model until now without charge, they have supported to bailment return many shipments to AAT without charge, while they have to hire the third party for those trucks. You can ask N.Bee and K.buyer-Sittichai about this.
I think NHK can pay for this claim but how about the future request from AAT. Please kindly consider.
