4420.90.45.00 - Not lined with textile fabrics

This HTS classification, 4420.90.45.00, pertains to a specific subset of wooden boxes, cases, and chests. It encompasses articles designed for storage or display of various items, such as jewelry, silverware, cigars, cigarettes, microscopes, tools, or utensils, when these items are constructed of wood. Crucially, the defining characteristic of this category is that these wooden containers are *not* lined with textile fabrics. This exclusion is key to distinguishing them from other similar wooden articles.

The primary distinction for this category lies in its exclusion of textile lining. Its sibling category, 4420.90.65.00, specifically covers identical types of wooden boxes, cases, and chests that *are* lined with textile fabrics. Therefore, when classifying an article, the presence or absence of textile lining is the decisive factor in determining whether it falls under 4420.90.45.00 or its sibling. This classification emphasizes the material composition and construction of the interior of the container as a primary classification criterion.

As this HTS code represents a leaf node within the Harmonized Tariff Schedule, there are no further subcategories to introduce. Classification within this code is definitive based on the product meeting the criteria of being a wooden box, case, or chest for the specified purposes and *not* being lined with textile fabrics. Importers and exporters should carefully examine the interior construction of wooden containers to ensure accurate classification.
