阿拉伯联合酋长国采购需求：黑白超声、彩色多普勒超声、心电图、数字X光、病人监护仪

I'm interested in learning more about your product pricing and the purchasing process for international customers, specifically from the United Arab Emirates. Could you provide a detailed breakdown of the costs involved, including any minimum order quantities or discounts for bulk purchases? Additionally, I'd like to know about the shipping options available for your products. What shipping methods do you offer, and what are the estimated costs and delivery times for sending items to the UAE? Any information on customs duties or additional fees would also be helpful. Thanks!
