4421.91.70 - Pickets, palings, posts and rails, the foregoing which are sawn; assembled fence sections

This HTS category, 4421.91.70, encompasses various articles of wood, specifically those made of bamboo, which are sawn and intended for use in fencing. This includes individual components such as pickets, palings, posts, and rails, as well as pre-assembled fence sections. The key characteristic is that these wooden components are processed through sawing and are designed for the construction of fences.

Distinguishing this category from its siblings, it is important to note that it specifically covers fencing-related wooden articles of bamboo. Sibling categories such as wooden dowel pins, blinds, shutters, screens, shades, toothpicks, skewers, and clothespins, while also being "other articles of wood," serve entirely different purposes and are not intended for fencing applications. Similarly, canoe paddles are distinct sporting equipment.

The subcategories within 4421.91.70 provide further refinement based on the assembly of the fencing components. The subdivision "Assembled fence sections" (4421.91.70.20) covers units that are already joined together to form a complete fence panel, offering a more ready-to-install solution. The "Other" subcategory (4421.91.70.40) would then capture individual sawn bamboo components like pickets, posts, and rails that have not yet been assembled into a section.
