3906.90.20.00 - Plastics

This HTS category, 3906.90.20.00, specifically covers "Other" acrylic polymers in primary forms that do not fall under more specific subheadings within Chapter 39. Acrylic polymers are synthetic resins produced by the polymerization of acrylic acid or its derivatives, such as methacrylic acid and its esters. In their primary forms, these can include powders, granules, pellets, or liquid forms (unless otherwise specified by a more detailed classification). This designation signifies that the material is an acrylic polymer but does not possess the specific characteristics or intended use that would place it in a more granular subheading.

The distinction between this category and its sibling, 3906.90.50.00 ("Other"), lies in a potential further breakdown or alternative classification at this level which is not further detailed here. However, generally speaking, where multiple "Other" classifications exist at the same level, careful review of all available subheadings within the parent category is crucial. If a specific attribute or composition of the acrylic polymer is not explicitly covered by a preceding subheading and is not directed to the "Other" sibling category based on specific tariff notes or judicial precedent, then this classification would apply.

As this is a leaf node, there are no further subcategories under 3906.90.20.00. Therefore, classification into this code signifies that the acrylic polymer in its primary form is not further divisible into more specific classifications within the HTS. Classification here implies that the goods meet the general definition of acrylic polymers in primary form but do not fit into any other more narrowly defined HTS codes within heading 3906.
