Parts & Accessories for Automatic Data Processing Machines

If the printed circuit assembly is designed and marketed specifically for ADP machines of heading 8471, it belongs under 8473.30 (specifically 8473302000 in the US schedule). If the assembly is equally suitable for use with machines across two or more of headings 8469–8472 and cannot be identified with a single heading, 8473.50 is the correct classification. Importers should retain technical specifications and product literature to support the classification decision.

US Customs and Border Protection applies a substantial transformation test for non-preferential origin. For ADP parts, CBP has generally found that board-level assembly operations alone may not confer Vietnamese origin if the essential character derives from components manufactured elsewhere. Importers should obtain a detailed bill of materials, manufacturing process description, and supplier declarations to support an origin determination — particularly given the Section 301 implications for Chinese-origin goods.
