离子交换树脂类化学制剂 001-918

07-20-2004 - Ion-exchange resins are in the nature of chemical preparations, commonly used for water purification, water softening, and manufacture of food and pharmaceutical products. These goods are finished products and are not in the nature of unprocessed resins used for further manufacture into another semi-finished or finished resin product. Thus, unlike an identification for "synthetic resins," which must include an indication that the goods are "unprocessed" for classification in Class 1, it is not necessary to indicate that the goods in this entry are "unprocessed." On 08-05-2021, this 07-20-2004 entry "Ion-exchange resins [chemical preparation]" was modified to "Chemical preparations in the nature of ion-exchange resins" to add the wording "in the nature of" and incorporate the bracketed wording into the identification to clarify the nature of the goods.
