Each metal covered by heading 8112 has its own dedicated subheading cluster organized by form: unwrought and powders, waste and scrap, and wrought articles. Identify the metal first, then determine whether the shipment is unwrought/powder, waste/scrap, or a wrought article. For metals grouped together in the residual subheadings (811292 and 811299), the same form-based logic applies, and the specific metal should be declared on the entry documentation.

Beryllium and beryllium-containing alloys are subject to OSHA's beryllium standard, which sets strict permissible exposure limits due to the risk of chronic beryllium disease. While OSHA requirements apply to downstream processors rather than to the import entry itself, importers supplying US manufacturers should ensure that Safety Data Sheets and handling instructions accompany shipments, and that customers are aware of the applicable workplace safety obligations.
