What I believe you may be trying to say is:
"1000 pcs of the goods have already been reworked but 95 pcs of the goods are still in HK.
We are sending 5 empty cartons for the shipment and will advise you of the carton numbers once we have shipped them to you.
Please advise when will you return these goods to China for rework."
Please let me know if this isn't what you meant and I'll have another go.
