废纸的分类一般按废纸的来源和废纸纤维的种类来划分，但世界各国废纸分类的方法和标准有较大的差异。
目前我国造纸工业所用的废纸分为两大类。
一类是国内废纸。主要有旧瓦楞纸箱、书刊杂志纸、旧报纸、纸箱厂的边角料、印刷厂的白纸切边、水泥袋、混合废纸及杂废纸等。国内废纸还没有全国统一的质量标准，目前正在制订之中。
另一类是进口废纸。主要有美国废纸、欧洲废纸及日本废纸，华南沿海部分纸厂使用一些香港废纸。
(一)国外废纸的分类
联合国粮农组织按废纸用途将废纸分为四大类：新闻纸和书籍废纸、纸板箱废纸、高质量废纸及其它废纸。
日本将废纸分为9类：上等白纸卡纸、特白中白马尼拉纸、有
色道林纸、证券纸、牛皮纸、报纸、杂志纸、瓦楞箱板和硬纸板。
英国将废纸分为11类；不含机械浆的白色未印刷废纸、不含
机械浆的白色已印刷废纸、含机械浆的白色和轻度印刷废纸、不含机械浆的有色废纸、含机械浆的重度印刷废纸、有色牛皮纸和马尼拉纸、新的牛皮挂面纸板、容器废纸、混合废纸、有色卡纸和含杂质废纸。
德国将废纸分为低级、中级．高级和保强废纸四大类。后者包括用过的防水或不防水的牛皮纸袋，用过或未用过的纯硫酸盐浆纸、旧瓦楞箱纸等。
美国将废纸分为三大类：纸浆代用品、可净化的废纸和普通废纸。纸浆代用品指白纸与白纸的切边，这类废纸经打散成纤维后不作进一步处理即可作为成浆使用。可净化的废纸经脱除印刷油墨后即可成浆使用。普通废纸包括旧报纸、旧瓦楞纸箱和混合废纸等。另一更细的分类法是将废纸分为47种，另列特殊等级7种，并颁布了《废纸原料标准》，使每个类别的废纸均有明确的质量标准。
我国进口美国废纸较多的品种有旧瓦楞箱纸板(AOCC)、旧报纸（ONP)、旧杂志纸(OMP)，另有少量纸的切边(DLK)、混合边废纸(MOW)、分选白账簿纸(SWL)、分选色账簿纸(SCL)、计算机打印文件纸(CPO)及双面牛皮箱纸板边角料(NDLK)等。
美国废纸标准和欧洲废纸标准对废纸的分类标号有所不同。这里以美国废纸标准分类号为基准介绍几种常见进口废纸。
