The US has maintained antidumping duty orders on certain steel fasteners — including nuts, bolts, and screws — from several countries over the years. Importers must check the current scope of active orders with the Department of Commerce and CBP's ADCVD portal, as scope rulings can determine whether a specific fastener type and steel grade falls within an order's coverage.

Decorative buttons used primarily as ornamentation on apparel are generally classified in HTS Chapter 96, while functional snap fasteners, hooks, and slide fasteners for garments fall under Chapter 83 or Chapter 96 depending on their base material and mechanism. The distinction matters because duty rates and any applicable trade-remedy exposure differ between chapters, and misclassification is a common audit finding for apparel accessory importers.
