荷兰采购需求：门到门送货、海运、空运、铁路运输、门到门海运、国际空运

I'm looking to ship around 600-800 kg of general cargo from China to Amsterdam. Could you provide me with a detailed breakdown of the shipping costs for this weight range? Additionally, I'd like to know any other relevant charges that might be applicable, such as customs fees or handling charges. It would be great if you could also share the estimated transit time and any available shipping options. Understanding these details will help me make an informed decision. Thanks for your assistance!
