I am reaching out to inquire about the availability and pricing for powder grade materials with specific GSM characteristics. We are interested in options that range from 300 to 450 GSM, as these grades align with our current production needs. Could you provide details on the types of powders you offer within this range, including any specifications or variations available? Additionally, it would be great to know about the minimum order quantities, lead times for delivery, and any bulk pricing options you might have. We are looking to establish a reliable supply chain, so any information regarding your quality control processes and certifications would also be valuable. Thank you for your assistance with this inquiry!
