英语翻译
In recent years the PPS has maintained a tin stock of around 2,000 tonnes as a service to small and medium-sized manufacturers using the metal and bought a similar volume each year through tenders.PPS不用译,tin是锡的意思,stock是库存的意思

这句英文本身写的实在差劲：using the metal 语法和用法都不对,原文的意思是对于中小工厂的锡金属需求吧?直接写usage就足够了,锡是金属毫无疑问,不需要再提metal.bought是个很口语化的单词,改成purchases.and后面也有逻辑问题,应该是每年持续购入2000吨左右以使得存量保持在这一数字……总之orz,给你整个重写吧：应写为In recent years PPS keep purchasing an amount of around 2000 tons of tin each year from tenders in order to maintain a stock of similar amount as a service to small and mid-sized manufacturers' usage.
tons和tonnes无区别.
很无语,不过还是严格按照原文给你翻译：
为服务于中小规模制造公司（或者工厂）,近年来PPS不仅持续保持锡的存量在2000吨上下,并每年从供货商处购入这一数量.
