美国采购需求：电力、建筑供暖、水利、污水处理、石油化工、矿山冶金

I'm reaching out to inquire about the availability of a couple of specific parts. Firstly, I'm interested in a total of 2 units of the first item mentioned previously, along with 4 units of another component that I also referenced. It's crucial for us to ensure that these items meet our quality standards and specifications. Could you please provide details on the pricing, lead times, and any minimum order quantities? Additionally, if you have any documentation like datasheets or compliance certifications, that would be really helpful. Looking forward to your prompt response so we can move forward with this order efficiently. Thanks!
