With regard to the product of approx. 5,000 kg (0.8 × 109) , there are still two processes have to be done at Mitsubishi Shindo (MSD), which are the slit process and, the inspection and packing process.
It is to be completed and shipped during the week containing the date of 11th and 12th.

We ask for your understanding and cooperation in this matter.

Good day, Mr. AAA. 
 
We have confirmed our balance sheet. 

1) It appears that we won't be able to have the product of 9,000 kg arrived in January, 2019. 
As initially scheduled, we plan to ship 6,000 kg in January 2019.
 
2) Are there any updates on A140X080X1200? We have sent the following message: building on the balance sheet we received on July 13th, we have already prepared to ship for another 6,000 kg.
 
We are looking for your reply. Thank you.
