I'm reaching out to inquire about your pricing and lead time for an order of 40kg of the material we discussed previously. We're looking for both bulk pricing options and any relevant discounts you might offer for larger quantities. Additionally, please include information about availability and if you have any current promotions. Understanding your production capacity and shipping timelines is crucial for our planning, so any details you can provide regarding lead times would be greatly appreciated. If you have any technical data sheets or product specifications available, that would also be beneficial to review as we finalize our purchasing decision. Looking forward to your prompt response!
