Last updated: April 2026 dataHard disk drives, solid-state drives, tape drives, and other data storage units for ADP systems — presented alone or as part of a broader system — are classified under this heading. The storage media sector has seen significant supply-chain concentration, with a handful of manufacturers in East and Southeast Asia dominating global output, making diversification and lead-time risk a recurring concern for enterprise procurement teams. Importers should also monitor Section 301 applicability by specific HTS subheading, as coverage has varied across different storage technologies and form factors.

Both HDDs and SSDs generally fall within the storage units heading for ADP systems, but the specific 10-digit HTS subheading may differ based on technology type and capacity. Given that Section 301 applicability can vary at the subheading level, confirming the precise classification for each product type before importation is advisable.
Customs entries for storage units typically require a commercial invoice with a detailed product description (technology type, interface, capacity), a packing list, and — where applicable — a manufacturer's specification sheet. If the goods are subject to Section 301 or antidumping measures, a certificate of origin or other origin documentation will also be required.
