沙特阿拉伯采购需求：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 a package from China to Saudi Arabia and want to know the cost per kilogram for DDP (Delivered Duty Paid) shipping. It's essential for me to understand all the fees involved, including shipping and any customs duties that might apply upon arrival. Additionally, could you provide information on estimated delivery times and any specific requirements or documentation necessary for this shipment? Knowing this will help me make a more informed decision and plan accordingly. Looking forward to your detailed offer!
