印尼客户索要赔款

今天遇到一个大问题，我们前段时间出口到印尼一台机床，由于我们车间的工人干活实在太不负责任，发过去的机床的日期为2011.12.20，而且机床整体来说比较脏，在客户清关的时候，被海关查验的时候归为2手机床，由此产生了很多费用还有税。机床价格3500美元，客户索赔1212.5美元 请问： 印尼对二手设备的进口有什么政策？？？客户索赔是否合理？ 以下是客户邮件内容： please find attached invoices from my freight forwarder company, us freight services for your review and immediate action. invoice 7629??idr 17,475.000.00 or usd 1,745.00 invoice 7702??usd 338.40 invoice 7703??usd 5,000,000.00 or usd 500.00 total freight & storage charges excluding duties and taxes.......? ?? ?usd 2583.40 of the usd 2583.40 only 2 invoices being 7629 and 7703 marked in pink where the costs should be borne by tengzhou mainland machine tool co. ltd., for their neglience being as follows,- invoice 7629 1.??undertable? ?? ?? ?? ?? ?? ?? ?? ???idr 1,500,000.00? ?? ?? ? usd 150.00 2.??warehouse inv#009100? ?? ? idr 3,600,000.00? ?? ? usd 360.00 3.??warehouse inv#009099? ?? ? idr 2,025,000.00? ?? ? usd 202.50 invoice 7703 1. undertable? ?idr 5,000,000.00 usd 500.00 total claim amount.....usd 1,212.50 kindly transfer the amount due to us asap.
