尼泊尔采购需求：C2S艺术纸、铜版纸、光面纸、双面纸、打印纸、优质纸

I'm interested in purchasing 3 containers of your kote paper. Could you please provide me with the latest pricing details, including any bulk order discounts you might offer? I'm also curious about the available grades and specifications for the paper, as well as your production lead times. Additionally, please let me know if you can meet specific quality certifications or standards that I might require. If it's possible to get samples before placing a larger order, that would be great too. Looking forward to your prompt response so we can move forward!
