4806.20.00.00 - Greaseproof papers

This category, HTS 4806.20.00.00, specifically covers greaseproof papers. These are papers that have been treated or manufactured to resist the passage of grease and oil. This treatment typically involves chemical processing or calendering to achieve a dense, non-porous surface that prevents greases from penetrating the paper, making them suitable for food packaging and other applications where oil resistance is crucial.

Greaseproof papers are distinct from their sibling categories within HTS 4806. Vegetable parchment (4806.10.00.00), for instance, is produced by treating paper with sulfuric acid, giving it a translucent appearance and enhanced strength and resistance to moisture and grease. Tracing papers (4806.30.00.00) are characterized by their transparency and smoothness, designed for technical drawings and reproductions. Glassine and other glazed transparent or translucent papers (4806.40.00.00) are also highly glazed and transparent or translucent, often used for decorative purposes or as packaging materials where visibility of contents is desired. The primary differentiator for greaseproof paper is its specific performance characteristic of oil and grease barrier properties.

As this is a leaf node in the HTS structure, there are no further subcategories for HTS 4806.20.00.00. Classification at this level is based on the inherent properties of the paper as described, primarily its resistance to grease penetration, which distinguishes it from other specialized papers within the broader heading of glazed transparent or translucent papers.
