Dear Wannipa-san,
Thank you for your inquiry.
TCP’S WH70 price is a kind of special price and available volume is limited (500mt/month in total).
BSCB pricing rule for BTMT is same price as TCP.
On the other hand, BSCB pricing rule for TBSC is same price as TCB.
So, we have to maximize TCP volume in TBSC and minimize TCP volume in BTMT to make balance.
Regarding TCB price, they agreed to base 80USD price reduction with Y15 allocation volume and TCB WH70 price is even lower than Black Cat.
Although TCB price is higher than TCP’s special price, I believe TCB price is competitive.
In addition, TCP might stop this special price because TBSC & BTMT total purchase volume of all the grades is less than their target volume recently.
Considering the above situation, I made Y15 allocation.
I would highly appreciate your kind understanding.
If you have any question, please let me know.
Best regards,
Satoshi Shindo
