Overview

This HTS classification, 9902.11.54, pertains to a specific type of copolymer: Poly(ethylene-ran-(2-norbornene)). This material is characterized by its composition, containing approximately 64% ethylene by weight and a minimum of 3% polyethylene. A key distinguishing physical property is its glass transition temperature, which falls within the range of 78°C. It's important to note that this classification falls under Section XXII, relating to temporary legislation and modifications proclaimed pursuant to trade agreements and agricultural adjustment acts.

Given that this is a leaf node, there are no further subcategories to explore under 9902.11.54. Its specific nature as a defined copolymer with precise compositional and thermal properties distinguishes it from broader categories of plastics or polymers that might exist at other HTS levels. The "provided for in subheading 3911.90.90" note indicates its primary classification under general provisions for other plastic and articles thereof, with Chapter 99 applying specific temporary or trade-related modifications.
