Is it possible for you to produce such AC? If yes, please give us price CIF Saint-Petersburg, Russia and FOB China and send your specification!
Also I would like to know there are your plant and office situated? Are they in one place?
What is your monthly production capacity? Do you have a constant supply on your warehouse?
Can you also tell me, is it possible for you to make bags for activated carbon with our logo and other information?
What is the terms of payment?
Also it will be very nice if you send me some brochures or presentation of your company.
Hope for your promt reply. We need your answer ASAP! Hope for your understanding.
Best Regards,
