HTS heading 8423 is a four-digit product category for weighing equipment and related goods. It generally covers weighing machinery other than very sensitive balances, including scales, weight-operated counting or checking machines, separate weighing-machine weights, and parts designed for weighing machinery. The heading describes a broad family of products, not one final import classification.
To reach the correct eight-digit HTSUS code, first identify exactly what is being imported: a complete machine, a weight, or a part. Then use the more detailed subheadings and statistical provisions, which commonly distinguish the machine’s type, function, capacity, operating method, or the material and design of a component. The product’s actual construction and principal function matter more than its marketing name. Review the relevant HTSUS notes, classification rules, and the current tariff schedule; uncertain cases may require a customs broker or a binding ruling from U.S. Customs and Border Protection.
What to check
- Describe the item’s primary function, such as weighing, counting by weight, checking weight, or serving as a separate machine weight.
- Confirm whether the shipment is a complete scale or machine, a standalone weight, or a part specifically identifiable for weighing machinery.
- Record technical details including operating principle, maximum capacity, display or control method, and whether the item is manual, mechanical, or electronic.
- Compare the product with the exact wording of the 8-digit provisions and any applicable section, chapter, or heading notes; do not stop at heading 8423.
- Keep product specifications, photographs, manuals, and invoices that support the selected classification, and obtain broker or CBP guidance when the distinctions are unclear.

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.
