U.S. imports of Automatic Data Processing Units (NESOI) (HS 847180) totaled $2.8B in August 2026, imported from 70 countries.
Importers of Automatic Data Processing Units (NESOI) paid $222.4M in duties in August 2026, an average duty rate of 10.83% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Automatic Data Processing Units (NESOI) imports of $2.8B in August 2026 ran 58% above the year-to-date monthly average of $1.8B.
Last updated: August 2026 dataControl units, adapter units, and other ADP machine units not elsewhere specified — including units designed for incorporation into larger ADP systems — are classified under this heading, which serves as a catch-all for functional ADP subassemblies that do not meet the definitions of processing, storage, or input/output units. The US schedule distinguishes control or adapter units (8471801000), units for incorporation into ADP machines (8471804000), and other units (8471809000). Taiwan leads US import supply, with Vietnam and Mexico also significant sources. Because this heading is a residual category, classification disputes often arise when a subassembly could plausibly be classified as a part under heading 8473 instead; the distinction generally turns on whether the article is a functional unit in its own right.

A functional unit under 8471.80 performs a specific ADP function (control, adaptation, or processing) and is capable of being used in a system, whereas parts and accessories under 8473 are components that enable or support a machine's operation without being functional units themselves. The chapter notes and CBP rulings provide guidance, but the line can be fact-specific; consulting a licensed customs broker is advisable for novel configurations.
Network interface cards are generally classified under heading 8517 as communications apparatus, while GPU accelerator cards designed for ADP machines may fall under 8471.80 or 8473 depending on their configuration and how they are presented. CBP has issued binding rulings on specific products in this space, and importers should request a ruling for high-volume shipments to avoid reclassification risk.
