印度采购需求：三氧化二锑，cas 1309-64-4，sb2o3粉末，其他

I'm looking for a supplier for Antimony trioxide with a purity of 99%. Specifically, I'm interested in a particle size of around 1 micrometer. Please provide your best pricing for an order of 1 ton, as well as any relevant details regarding your production capabilities, lead times, and minimum order quantities. Additionally, if you have different variations of this product or can offer competitive pricing for bulk purchases, I'd love to hear about it. Understanding your shipping options and any bulk discount arrangements would also be helpful as I plan my procurement strategy. Looking forward to your prompt response!
