4804.39.20.00 - Condenser paper

This HTS classification, 4804.39.20.00, specifically covers "condenser paper" within the broader category of uncoated kraft paper and paperboard weighing 150 g/m² or less. Condenser paper is a specialized type of kraft paper characterized by its high purity, exceptional electrical insulation properties, and often a smooth, dense surface. It is primarily manufactured for use in the production of electrical capacitors, where its dielectric strength is critical for performance and safety.

This classification is distinct from its siblings, "wrapping paper" (4804.39.40) and "other" (4804.39.60). While all fall under the same parent headings, condenser paper is defined by its specific technical application and manufacturing standards, which necessitate properties beyond those typically found in general-purpose wrapping papers. The "other" category serves as a residual for kraft papers that do not fit the defined uses of condenser or wrapping paper.

As this is a leaf node, there are no further subcategories. Therefore, classification under 4804.39.20.00 relies on identifying the paper's intended use in capacitor manufacturing and its adherence to the requisite technical specifications, such as high tensile strength, controlled porosity, and excellent dielectric constant, which differentiate it from other kraft papers.
