2022版协调制度对品目8462的整体结构进行了比较大的修改。对现有子目进行了修订，并设立了新的子目，以反映技术发展和日益增加的商业意义，对品目84.62进行了修订。
在第八十四章新增章注释五：
For the purposes of heading 84.62, a “slitting line” for flat products is a processing line composed of an uncoiler, a coil flattener, a slitter and a recoiler. A “cut-to-length line” for flat products is a processing line composed of an uncoiler, a coil flattener, and a shear.”在品目84.62中，用于板材的“纵剪线”是由开卷机、卷矫平机、纵剪机和收卷机组成的加工生产线。板材的“定尺剪切线”是由开卷机、矫平机和剪切机组成的加工生产线。
