尼日利亚采购需求：门到门送货、海运、空运、铁路运输、门到门海运、国际空运

I'm interested in a 15KG product, and I would like to get more details about your offerings. Could you please provide specifications, pricing, and availability for this quantity? It's important for me to understand any available options or variations you might have in this weight range. Additionally, if there are any minimum order requirements or shipping details I need to be aware of, please include that information. I'm looking forward to your prompt response as I am keen to move forward with the procurement process. Thanks!
