Just spoken to TT/CB, Khun Saree guarantees delivery regularly in June. Meaning that he will arrange based on your SI.
He will wait for your SI on 20th May and plan his delivery accordingly. Please spread the delivery across the month.
Currently, he is still waiting for Raw Material and he would like to share the raw material situation with BTMT for your better understanding.
Nonetheless, he will give priority to BTMT.
Do advise us if you face any difficulty by end of this month.
