customs release meaning in Chinese

海关放行

However , if we retain custody of the shipment and are requested to deliver the shipment following receipt of the appropriate customs release paperwork from another customs broker following customs or other regulatory clearances , our delivery commitment time is modified by adding one business day for each day or portion thereof that our receipt of the paperwork is delayed
但若由本公司保管托运货件并负责于取得指定清关代理人交来之海关放行文件后送件，如海关放行文件延误，则每延误一天，本公司之送件承诺时间应顺延一个工作日，延误时间不足一天者按一天计算。
