About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS category, 8471.70.20.00, encompasses specific storage units designed for physical incorporation into automatic data processing (ADP) machines or their constituent units. These are typically hard disk drives (HDDs) or solid-state drives (SSDs) that are intended to be integral components of computers, servers, or other ADP systems, rather than standalone external storage devices. The key characteristic is their design for direct installation and operation within the chassis of a primary data processing machine.

Within the broader classification of magnetic disk drive units, this subheading specifically differentiates itself from its sibling category, 8471.70.10.00. The sibling category covers magnetic disk drive units that are either entered separately without their read-write unit already assembled, or where the read-write units are entered as individual components. In contrast, 8471.70.20.00 applies to complete, assembled magnetic disk drive units that are ready for integration into an ADP machine. The other sibling, 8471.70.30.00, acts as an "other" category for magnetic disk drive units not specifically classified elsewhere.

As this is a leaf node within the HTS classification system, there are no further subcategories to detail. Classification under 8471.70.20.00 hinges on the physical form factor and intended application of the magnetic disk drive unit. Importers and exporters should ensure that the units are indeed intended for internal installation and operation within ADP machines, and that they meet any specifications for disk diameter if applicable, to correctly apply this classification.
