我国作为铜的消费大国，国内铜矿的产量远远无法满足需求，大部分需要从国外进口。海关总署最新数据显示，上半年中国进口铜矿砂及其精矿同比增长8.6%。庞大的进口需求也催生了巨大的翻译市场，特别是在铜精矿销售合同翻译这一方面。以下是部分铜精矿销售合同中有关付款条款的双语条款，供参考：

示例一（简版）：

1. Payment/付款

1.1 All invoices or credit notes shall be in US Dollars and Cents and all payments shall be made in US Dollars and Cents.

所有发票或贷项凭据应以美元和美分计，所有付款也应以美元和美分支付。

1.2 Buyer shall open, in favor of Seller, through a bank acceptable to Seller in discretion, an irrevocable sight letter of credit (“L/C”) in USD for 100% of the provisional cargo value (allowing +/-10% variance in value and +/-10% variance in quantity), based upon pre-shipment weights and assays of payable metals at provisional prices which are the average of the ten (10) market days prior to the date of the pro-forma invoice issued for the purposes of opening the L/C.

基于装运前重量和计价金属的化验结果，买方应通过卖方自行决定接受的银行，按暂定价格（即为开立信用证而开具形式发票之日前十（10）个交易日的平均价格）开立以卖方为受益人的、以美元计价的不可撤销即期信用证（“信用证”），涉及价值为临时货物价值的100％（允许价值差额为+/- 10%和数量差额+/- 10％）。

1.3 The L/C shall be issued 10 days prior to the estimated shipment date. The L/C shall be advised through an international bank nominated by Seller, be available with any bank by negotiation and allow for multiple drawings. Such L/C shall be in form and substance acceptable to Seller. An L/C with any reference to, or clauses mentioning, sanction(s) is not allowed, if required by issuing bank, Buyer and Seller should negotiate in good faith to conclude a solution. All costs associated with the L/C arising at the opening bank shall be for Buyer’s account, while all costs outside the opening bank shall be for Seller’s account.

信用证应在预计装运日期前10天签发。信用证应通过卖方指定的国际银行通知，并可以在任何一家银行议付，并允许多次提款。此等信用证的形式和实质应为卖方接受。如果开证行要求，不允许信用证或相关条款提及制裁，则买卖双方应按诚信原则进行协商以达成解决方案。在开证行产生的与信用证有关的所有费用应由买方承担，而在开证行以外的所有费用应由卖方承担。

2. PAYMENT/付款

A)For CIF deliveries/CIF交付:

Letter of Credit/信用证:

Payment shall be secured by way of an irrevocable documentary Letter of Credit (the "LC") obtained by Buyer and such UC shall be issued at sight in US$ without any deduction, withholding, offset or counterclaim whatsoever by means of a fully workable irrevocable letter of credit, to be opened by a bank and in a form fully acceptable to Seller covering I 00% of the cargo value based on Seller's proforma invoice value, based upon pre-shipment weights and assays of payable metals at provisional prices which are the average of the ten (10) market days prior to the date of the pro-fonna invoice, and allowing a tolerance of+/- l0% in both quantity and/or amount.

付款应以买方获得不可撤销的跟单信用证（“信用证”）进行，开立的此等信用证应为以美元计价的即期信用证，且没有通过由银行开立、格式为卖方完全可接受的完全可行且不可撤销信用证进行任何扣减、预扣、抵销或反索赔。此等信用证涉及价值为卖方形式发票中货物价值的100%，基于装运前重量和计价金属的化验结果，按暂定价格（即形式发票之日前十（10）个交易日的平均价格）开立，并且在数量和/或金额上允许+/- 10％的允差。

2.1.The letter of credit must be opened prior to the estimated shipment date (LC Opening Date). Time is of the essence for the opening of the letter of credit.

信用证必须在预计装运日期（信用证开立日期）前开立。时间对于信用证的开立至关重要。信用证的开立应是卖方履行交付铜精矿义务的先决条件。如果卖方银行未在该日之前收到可行信用证，则卖方可以保留权利但没有义务：

(a)Buyer shall credit Seller Rate from the LC Opening Date, as per above paragraph, until the date the Letter of Credit has been opened at the London Interbank Offered Rate (LIBOR) or the Replacement Benchmark Rate in accordance with clause PAYMENT for a 3-month period, as published in the Financial Times on the first Banking Day after the bill of lading date, plus 3.5% per annum.

(b)delay the shipment of the Material, until such time that a Letter of Credit has been opened which is in fom1 and substance fully acceptable to Seller; and

延迟材料的装运，直到开立格式和内容令卖方完全接受的信用证为止；和

(c)simply to cancel the shipment. Any losses (including but not limited to: Rate for late UC opening / possible demurrage and detention costs / all costs for re-selling and dive11ing the material to another port and Buyer/Seller's storage costs) arising out of Buyer's failure to open a workable L/C in time shall be for Buyer’s account.

直接取消装运。因买方未能及时开立可行信用证而造成的任何损失（包括但不限于：延迟开立信用证产生的利息/可能的滞期费和滞留费/将材料再出售和运送到另一个港口产生的所有费用以及买方/卖方的仓储费用）应由买方承担。
