4805.24.90.00 - Weighing over 30 g/m²

This HTS classification, 4805.24.90.00, specifically covers testliner (recycled liner board) that weighs over 30 grams per square meter. Testliner is a type of paperboard primarily made from recycled fibers, often used in the production of corrugated cardboard packaging. The critical distinguishing factor for this category is its weight, falling into the upper range of the testliner classifications.

To properly classify testliner under heading 4805.24, it is crucial to consider its weight per square meter. This particular subcategory distinguishes itself from its siblings by excluding materials weighing 15 g/m² or less (4805.24.50.00) and those weighing over 15 g/m² but not over 30 g/m² (4805.24.70.00). Therefore, any testliner meeting the general description but weighing more than 30 g/m² will fall under this 4805.24.90.00 classification.

As this is a leaf node in the HTS, there are no further subcategories. Classification within this code is determined solely by the material type (testliner from recycled fibers) and the specific weight range indicated, which is over 30 g/m². This level of detail ensures precise identification for customs purposes, particularly for goods intended for packaging applications.
