About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS category, 3920.51.50.50, specifically classifies sheets of acrylic polymers, made of poly(methyl methacrylate), that are not flexible and contain flame retardant properties. These materials are typically rigid, solid sheets, not in film or foil form, intended for applications where fire safety is a primary concern. The presence of flame retardant additives is a key defining characteristic for classification under this heading.

Distinguishing this category from its sibling, 3920.51.50.90, hinges on the specific presence of flame retardant additives. While both categories cover other non-flexible sheets of poly(methyl methacrylate), this heading is reserved for those that have undergone treatment or incorporation of flame-retardant substances. The sibling category would encompass similar sheets that do not possess this particular fire-retardant characteristic.

As this is a leaf node, there are no further subcategories to introduce. Classification decisions within this heading will therefore rely on confirming that the imported goods meet the criteria of being non-flexible sheets of poly(methyl methacrylate) and demonstrably contain flame retardant properties, differentiating them from general-purpose or other specialized acrylic sheets.
