The next thing I'd like to bring up for discussion is packing.
We'd like to hear what you say concerning the matter of packing.
Please make an offer indicating the packing.
Your opinions on packing will be passed on to our manufacturers.
We've informed the manufacturer to have them packed as per your instruction.
I'm sure the new packing will give your clients satisfaction.
Normally, packing charge is included in the contract price.
The machines must be well protected against dampness, moisture, rust and shock.
Please pack the goods very carefully.
The crux of packing lies in protecting the goods from moisture.
I think you'll find the packing beautiful and quite well-done.
We have especially reinforced out pacing in order to minimize the extent of any possible damage to the goods.
At your convenience, I would really appreciate you looking into this matter/issue。
I sincerely apologize for this misunderstanding!
I apologize for the late asking but we want to make sure the correctness of our implementation ASAP。
Thank you very much if you can answer it immediately.
Can you please reply before tomorrow?
