HTS heading 8473 is a parts-and-accessories category for machines classified in headings 8470 through 8472. In plain language, it covers qualifying items designed for use solely or principally with those machines, excluding covers, carrying cases, and similar protective items. The related machine headings generally include certain calculating, accounting, and data-processing equipment, but the exact machine classification should be confirmed before using heading 8473.
Heading 8473 is only a 4-digit starting point, not the final tariff classification. To reach the correct 8-digit subheading, identify what the part or accessory is and follow the available breakouts, which may distinguish items by type, function, construction, or material. Classification can also depend on whether the item is a recognizable part, a general-purpose component, or an accessory that is principally used with the covered machines.
What to check
- Confirm the complete HTS classification of the machine the item is designed to serve, and verify that it falls in heading 8470, 8471, or 8472.
- Describe the item by its actual function and physical characteristics, including whether it is a part, accessory, replacement component, or protective case.
- Read every 8-digit breakout under heading 8473; check whether the options separate the item by material, type, function, or another stated characteristic.
- Confirm that the item is suitable for use solely or principally with the covered machines, rather than being a general-purpose component used across many products.
- Keep product specifications, photographs, technical literature, and supplier information supporting the classification; request customs-broker or ruling advice when the intended use or product identity is unclear.
HTS heading 8473 summary
Parts and accessories is a 4-digit product category containing 2 published product-code lines in this snapshot. A heading does not carry one universal duty rate; classification must be narrowed to the line matching the product facts.
How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.

How do I choose the right code within this category?
