马来西亚采购需求：植物用硝酸钙，硝酸钙价格，硝酸钾粉

I'm interested in sourcing calcium nitrate for an upcoming project. Could you provide detailed information on the available grades, including their specifications and purity levels? Additionally, I'm keen to understand the quantities you can offer and whether you have any bulk purchasing options. It would be great to know your pricing structure, lead times for delivery, and any potential discounts for larger orders. If you have product samples or data sheets, please share them as well. Looking forward to your prompt response so we can move forward efficiently.
