4418.50.00 - Shingles and shakes

HTS category 4418.50.00 specifically covers shingles and shakes made from wood. These are typically thin, overlapping pieces of wood used for roofing and siding. Shingles are usually sawn, while shakes are often split, giving them a more rustic appearance, though both fall under this heading when manufactured from wood.

This category is distinguished from its siblings by its specific focus on these particular roofing and siding components. For instance, while other subheadings within 4418.50 might cover assembled flooring panels or other building joinery and carpentry items like doors and windows, 4418.50.00 is dedicated solely to shingles and shakes. Formwork for concrete construction (4418.40.00) and posts and beams (4418.30) represent entirely different applications of wood in construction.

Within the 4418.50.00 classification, further distinctions are made to refine the classification. The subcategory "Shingles" would apply to wood pieces specifically designed and manufactured to function as roofing or siding materials. The "Other" designation (4418.50.00.50) is reserved for any remaining wooden shingles or shakes that do not fit into a more specific subheading, ensuring comprehensive coverage of these wood products.
