挪威采购需求：CEO2，CEO2专用抛光粉，氧化铈，纳米材料

I'm interested in sourcing cerium oxide with a particle size around 2.5 microns. My main purpose for this product is polishing rocks, which I do as a hobby and for some local sales. I anticipate that a one-kilogram supply will likely last me about a year given my usage rate, but I'm open to purchasing more if I see demand for selling online. Could you please provide details on pricing, minimum order quantities, and lead times for delivery? Additionally, I'd like to know about any specifics regarding packaging and shipping options. Looking forward to your response!
