您好，想询问一下关于焦油回收系统的HS Code，客户对此产品的描述如下：LIST supplies to its customers in China complete process systems to recover TDI from a waste stream, so called “LIST TDI Recovery Systems”. Such a LIST recovery system consists of LIST proprietary key equipment, auxiliaries from LIST and third parties as well as Engineering Documents; the system comes pre assembled but needs final assembly and electrical and instrument wiring on site in China.

This LIST key equipment is unique and not available from other parties. A similar product but not exactly in the same family of products is a large extruderLIST为公司名称
