U.S. imports of Automatic Data Processing Storage Units (NESOI) (HS 847170) totaled $2.6B in August 2026, imported from 63 countries.
Importers of Automatic Data Processing Storage Units (NESOI) paid $6.3M in duties in August 2026, an average duty rate of 0.25% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Automatic Data Processing Storage Units (NESOI) imports of $2.6B in August 2026 ran 16% above the year-to-date monthly average of $2.2B.
Last updated: August 2026 dataHard disk drives, floppy disk drives, and other magnetic storage units for ADP machines are classified here, with the US tariff schedule drawing distinctions based on disk diameter (greater than 21 cm versus smaller), cabinet assembly status, and whether an external power supply is included — distinctions that reflect the heading's long history and now apply primarily to hard disk drives and residual storage formats. Thailand and the Philippines are major US import sources for hard disk drives under this heading, a supply concentration that creates meaningful logistics and geopolitical risk exposure for enterprise storage buyers. Importers should pay close attention to whether drives are shipped with or without external power supplies and whether they are assembled in cabinets, as these factors determine which of the eleven US tariff lines applies.

The tariff schedule retains legacy lines for flexible (floppy) magnetic disk drives because the legal text has not been updated to remove them. Obsolete formats that technically meet the floppy drive description should still be classified in those specific lines (e.g., 8471704035 or 8471705035) rather than in the residual NESOI lines, to ensure accurate classification.
Yes. The US schedule explicitly separates hard disk drive units without an external power supply (8471704065) from other disk drive units without a base and external power supply (8471704095), and provides additional lines for drives with full cabinet assembly. Importers must confirm the power supply configuration at time of entry to select the correct line.
