I'd like to inquire about your offerings of PAM and PAC. We're looking to source these products for our upcoming projects, and it is essential for us to ensure high quality and competitive pricing. If you could provide detailed specifications, available quantities, and your best pricing options, that would be greatly appreciated. Additionally, we're interested in understanding your lead times and any minimum order requirements you may have. It would also be helpful to know about your production capacity and any certifications your products may have. Please feel free to share any relevant data sheets or product brochures that could assist us in making our decision. Looking forward to your prompt response!
