[0002] In 2023, the national standard "regenerated pulp" was released, ending the long-term situation of no applicable standard for imported regenerated pulp as a raw material for papermaking fibers. The standard specifies a series of test items for pulp obtained by sorting, dry or wet disintegration, screening and other treatments, including physical items such as ash content, un-disintegrated fiber components, inclusions, mechanical strength, and environmental protection items such as heavy metals. Reviewing the customs supervision of imported regenerated pulp after 17 years, goods imported in the form of pulp often have a potential "foreign garbage" risk. Such regenerated pulp does not need to be dried by a pulp board machine after being made by a "hammer tearing" method, so it naturally reduces the requirement for inclusion rate, and can also change the primary form of waste paper at a lower cost. Therefore, it appears in large quantities in import and export trade. Among them, the most typical is the fluffy dry pulp made by "hammer tearing", and during the processing, un-disintegrated paper sheets and non-fiber inclusions can still be found in such samples.
