4418.91.10.00 - Drilled or notched lumber studs 🖩

This HTS classification, 4418.91.10.00, specifically covers drilled or notched lumber studs. These are pre-processed wooden structural members, typically used in building construction, that have undergone operations such as cutting holes (drilling) or creating indentations (notching) to facilitate assembly or the passage of utilities like wiring or plumbing. The primary material for these studs is lumber, as opposed to bamboo.

This category is distinguished from its sibling, 4418.91.91, which encompasses "Other" bamboo joinery and carpentry items. While both fall under the broader category of "Other" articles of bamboo within builders' joinery and carpentry, 4418.91.10.00 is exclusively for lumber studs that are drilled or notched, whereas the sibling covers any other bamboo-based joinery or carpentry products not otherwise specified.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification within 4418.91.10.00 relies on accurately identifying the product as a lumber stud that has been specifically drilled or notched for construction purposes. The key determinative factors are the material (lumber), the form (stud), and the presence of drilled or notched features.
