由于中国要控制四氯化碳的使用，目前生产该物的厂家只剩下4家，所以货物的供应数量减少，如果需要订货，必须提前1个月。由于供应减少，导致该物品10月份的价格上涨了大约USD250。
Usage of carbon tetrachloride (CTC) is under control in China, so, only 4 factories remain. Therefore, supply quantity decreases. Please place an order one month in advance. Due to supply shortage, the price in October has been increased by USD 250.

另外，从2010年开始，国家要求厂家变更该物品的生产工艺，让该品的生产过程符合环保要求，从目前的试点厂家来看，其生产成本每短增加了大约6000-7000元人民币。
综上所述，如果需要订货，请注意提前1个月通知。2010年价格会有比较大的变化，订货前请来电查询.
