8903.99.21.10 - With hulls of metal

This HTS classification, 8903.99.21.10, specifically covers outboard motorboats that are distinguished by having their hulls constructed from metal. This category falls under the broader heading of "Other" vessels for pleasure or sports, encompassing those not explicitly defined by other subheadings within the 8903.99.21 grouping. The key defining characteristic for classification into this code is the material composition of the boat's hull.

It is crucial to differentiate these metal-hulled outboard motorboats from their sibling categories. HTS code 8903.99.21.20 applies to outboard motorboats where the hull is made of reinforced plastics, and 8903.99.21.90 covers any other outboard motorboats not classified by material in the preceding subheadings. Therefore, the presence of a metal hull is the sole criterion for inclusion in 8903.99.21.10.

As a leaf node, this classification does not have further subdivisions. Its scope is therefore narrowly defined to include all types of outboard motorboats where the hull material is metal, regardless of other design features or intended uses within the realm of pleasure or sports boating. Examples would include aluminum or steel outboard motorboats designed for fishing, waterskiing, or general recreational cruising.
