Last updated: April 2026 dataArchitectural hardware—door hinges, window stays, curtain rod brackets, and similar base metal fittings not elsewhere specified—feeds directly into the residential and commercial construction sectors, where specification standards and finish requirements drive sourcing decisions. Antidumping and Section 301 measures have affected certain categories of base metal hardware from China, making duty-order research a routine step for importers. Correct classification under this heading requires confirming the article's intended use in buildings rather than furniture or vehicles, as the SITC structure separates these end-use categories.

The determining factor is the article's designed end use: fittings intended for permanent or semi-permanent installation in a structure (walls, doors, windows, ceilings) classify as building fittings, while those designed to be attached to or integrated with furniture pieces fall under the furniture fittings heading. When an article is marketed and sold for both uses, the primary or predominant use at the time of importation typically governs classification.
Certain base metal building hardware products from China have been subject to antidumping and countervailing duty orders. Importers should check the current scope of active orders with the International Trade Administration and confirm applicability with a licensed customs broker before entry.
