HTS heading 9026 is a broad product category for instruments and apparatus that measure or check a physical variable in a liquid or gas. It commonly includes flow meters, level gauges, pressure-measuring instruments such as manometers, and heat meters, along with qualifying parts and accessories. The heading is limited by exclusions: certain instruments covered by headings 9014, 9015, 9028, or 9032 belong elsewhere.
To reach the correct 8-digit HTSUS code, first identify the instrument’s principal function and the variable it measures or checks. Then follow the applicable subheading structure, which may distinguish the product by type, measuring method, construction or material, whether it is an instrument or a part, and other product characteristics. The complete product specifications—not just its marketing name—must match the wording of the selected subheading and any relevant legal notes.
What to check
- Confirm exactly what the product measures or checks: flow, level, pressure, heat, or another variable, and whether it measures liquids, gases, or both.
- Determine the instrument’s operating principle and construction, including whether it is electronic, mechanical, optical, or another type, and check whether the subheadings distinguish these features.
- Separate a complete instrument from a dedicated part or accessory; do not classify a replacement component as the complete measuring device.
- Review the exclusions for headings 9014, 9015, 9028, and 9032 before using heading 9026, especially for surveying, utility-metering, or automatic-control equipment.
- Use the product’s technical datasheet, drawings, manuals, and actual function to verify the full 8-digit code; request customs-broker or binding-ruling guidance when the classification is uncertain.

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.

Common questions
What products fall under HTS heading 9026?
Instruments and apparatus for measuring or checking the flow, level, pressure or other variables of liquids or gases (for example, flow meters, level gauges, manometers, heat meters), excluding instruments and apparatus of heading 9014, 9015, 9028 or 9032; parts and accessories thereof. To classify a specific item you must pick the matching sub-category and 8-digit code above; the right choice usually depends on the material and construction of the product.
How do I choose the right code within this category?
Start from the sub-categories (typically divided by material—for example cotton versus man-made fibers), then open the active 8- or 10-digit code that matches the product. When unsure, a licensed customs broker or a CBP binding ruling can confirm the classification.
