Payment： 30% as deposit by T/T and the balance 70% paid on receipt copy of B/L. 这是一条合同惯用条款，按此作为付款条件提供给买方就可以了。希望可以帮到你！

30%前TT(作定金),70%后TT,见提单付本付款Thirty percent shall be telegraghic transferred as down payment before (the shipment?原文说的“前”是指 装船前？ ) （可能是开始生产前 the production 呵呵）while the remaining 70% of the payment shall be telegraghic transferred at the sight of the copy of the (一般是 货已经装船shipped on board) bill of lading.原文应该要严谨一点。 工作顺利！
无痕之音
T/T at sight 是即期付款，是装运后付款T/T after sight 如是30天付款的应写成T/T after 30 days sight.T/T after shipment 是装运后买方拿到提单付款。

30%前tt(作定金),70%后tt,见提单付本付款这个国际贸易英语的专业翻译就是：thirtypercentprepaidbytt(telegraphictransfer)asdownpayment,whiletheremaining70%shallbepaidbyttatthesightofbillofladingcopy.
