加拿大采购需求：护肤品OEM、护肤品ODM、定制护肤品、护肤品制造商、护肤品供应商、中国化妆品工厂

I'm considering launching my brand and would like to explore the possibility of ordering your toothpaste and deodorant products under a private label. Could you share the minimum order quantities for these items? I'd also appreciate details on unit pricing, customization options like logo, packaging, and scent/flavor choices. Additionally, info on production and shipping timelines, relevant certifications such as GMP, MSDS, and COA would be great. I'm planning to sell on Amazon, so an authorization letter would be essential. Lastly, could you confirm if samples are available prior to placing a bulk order? Looking forward to your quick response!
