经过化学改性的天然聚合物的制造商和进口商是否有注册义务？

Are there registration obligations for manufacturers and importers of natural polymers that have been chemically modified?

天然聚合物是指由自然界中发生的聚合过程生成的聚合物，与提取过程无关（即，它们可能符合或不符合 REACH 法规第 3(39) 条规定的标准）。根据 REACH 法规第 2(9) 条，任何符合 REACH 法规第 3(5) 条标准的聚合物无需注册。这包括经过化学改性（例如，天然聚合物的后处理）的天然聚合物。出于实际原因，源自天然聚合物的单体物质、以单体单元形式存在的其他物质以及化学结合的物质可被视为“非分离中间体”，无需注册。用于化学改性天然聚合物并以化学方式结合在最终聚合物中的物质需要根据 REACH 要求进行注册。本常见问题解答已于 2008 年 10 月获得成员国主管部门 (REACH CA) 的同意。

Natural polymers are understood as polymers, which are the result of a polymerisation process that has taken place in nature, independently of the extraction process with which they have been extracted (i.e. they may or may not meet the criteria set out in Article 3(39) of the REACH Regulation). Following Article 2(9) of the REACH Regulation, any polymer meeting the criteria of Article 3(5) of the REACH Regulation does not have to be registered. This includes natural polymers, which are chemically modified (e.g. post-treatment of natural polymers). Monomer substance(s) or other substance(s) in the form of monomeric units and chemically bound substance(s) originating from the natural polymer can for practical reasons be treated as "non-isolated intermediates" and do not have to be registered. The substances used to chemically modify the natural polymer and which are chemically bound within the final polymer need to be registered according to the REACH requirements. This FAQ has been agreed by the Competent Authorities of the Member States (REACH CA) in October 2008.
