Hi,
Inspection is pending on last Friday, your QC cannot sure whether the power cord were correct, which had approved by Kmart. Please help to release shipment. For your information, these cargoes were used 7A “Sino” power cord, and we will show on the invoice
There are problems here, particularly with tenses, that make it hard for me to understand your meaning.
Inspection is pending on last Friday, Inspection has been pending since last Friday (?)
your QC (what is a QC?) cannot be (?) sure whether the power cord were (is? was?) correct, and has been (?) approved by Kmart. Please help to release shipment. For your information, these items use a 7A “Sino” power cord, and we showed this (?) on the invoice
Why don't you try to rewrite this and post it here again, so we can give you more help?
Best wishes, Clive
