4503.90 - Other:

This category, HTS Code 4503.90, encompasses "Other" articles manufactured from natural cork. Unlike the specific articles detailed in sibling categories, such as corks and stoppers (4503.10), this classification serves as a residual category for a diverse range of cork products that do not fit into more specialized headings within Chapter 45. The common characteristic uniting these items is their origin from natural cork and their form as manufactured articles, distinct from raw cork material.

The inclusion of "Other" signifies its role in capturing a broad spectrum of cork items. This could include, but is not limited to, corks for non-stopper applications, decorative cork items, or components made from natural cork that are not explicitly enumerated elsewhere. The intention is to ensure all manufactured articles of natural cork are accounted for within the HTS framework.

To provide further granularity, this category is subdivided into more specific subcategories. These subdivisions are designed to address distinct types of "other" cork articles based on their form, function, or common application. For instance, HTS 4503.90.20.00 covers disks, wafers, and washers made of natural cork, while HTS 4503.90.40.00 specifically addresses wallcoverings made from this material, reinforced as necessary. The residual category, HTS 4503.90.60.00, further captures any remaining "other" cork articles not meeting the criteria of these more specific subdivisions.
