8903.21.00.30 - Of a length not exceeding 4 m

This HTS classification, 8903.21.00.30, pertains to sailboats, specifically those that are not inflatable and may or may not have an auxiliary motor. The defining characteristic for inclusion in this subcategory is the vessel's length: it must not exceed 4 meters. This specifically targets smaller sailboats designed for recreational or sporting purposes.

This category is distinguished from its siblings primarily by its precise length limitation. Unlike 8903.21.00.35, which covers sailboats from over 4 meters up to 6.5 meters, and 8903.21.00.40, which includes those exceeding 6.5 meters but not more than 7.5 meters, this category is strictly for the smallest vessels within the "not exceeding 7.5 m" group. It isolates the most compact non-inflatable sailboats.

As this is a leaf node in the HTS database, there are no further subcategories within 8903.21.00.30. Therefore, the classification focuses solely on the precise length of the sailboat. Examples of vessels falling under this code would include very small dinghies, some types of personal sailing craft, and diminutive racing sailboats, all of which are non-inflatable and measure 4 meters or less in length.
