9902.11.84 - Sheets of plastics of poly(methyl methacrylate), noncellular and not reinforced, laminated, supported or similarly combined with other materials, not flexible, the foregoing of a kind used to produce counter tops or edging, cabinet tops, faces or edges for home or office furnishings (provided for in subheading 3920.51.50)

This HTS code, 9902.11.84, specifically classifies sheets of poly(methyl methacrylate) (PMMA) that are noncellular, not reinforced, and not laminated or combined with other materials. Crucially, these sheets are characterized by their non-flexible nature and are designed for use in the production of components such as countertops, edging, cabinet tops, and faces for home or office furnishings. This classification is located within Chapter 99, which pertains to temporary legislation, temporary modifications proclaimed pursuant to trade agreements, and additional import restrictions.

Unlike other entries within the broad HTS database, which cover a vast array of goods ranging from live animals to manufactured products, this particular code is highly specialized. It is distinct from the general classifications for plastics found in Chapter 39, as it falls under a temporary provision (Chapter 99) and refers back to a specific subheading (3920.51.50) within that chapter, indicating a particular trade or tariff treatment. The focus is on the specific material (PMMA), its physical form (non-cellular, non-flexible sheets), and its intended end-use in furnishings.

As this HTS code is a leaf node, it does not have further subcategories. Therefore, the classification hinges entirely on meeting all the specific criteria outlined in the description. Importers must ensure that the imported sheets precisely match the characteristics of noncellular, non-reinforced, non-laminated PMMA sheets intended for furnishing applications to qualify for this classification. Any deviation in material, flexibility, or intended use would necessitate classification under a different HTS code.
