HTS heading 9030 is a broad product category for instruments that measure or check electrical quantities, such as oscilloscopes and spectrum analyzers. It also covers instruments that detect or measure ionizing radiation, including alpha, beta, gamma, X-ray, and cosmic radiation. Certain parts and accessories for these instruments may also fall here. Electrical supply or production meters covered by heading 9028 are excluded.
The 4-digit heading is only the starting point. To reach the correct 8-digit HTS code, identify the instrument’s principal function, such as measuring electrical quantities, analyzing signals, or detecting radiation, and then follow the more detailed subheadings and statistical subdivisions. These subdivisions are usually based on the instrument’s type, function, or technical design—not simply its material. Parts must be classified based on what they are, what equipment they are designed for, and whether the tariff text specifically includes them.
What to check
- Describe the product’s primary measuring or detecting function, supported by the datasheet, user manual, and product specifications.
- Check whether the item is an instrument, a dedicated part, or an accessory; do not assume every component used with a 9030 instrument belongs in the same code.
- Confirm that the product is not an electrical supply or production meter covered by heading 9028 or another heading.
- Read every subheading and 8-digit statistical subdivision under 9030, including any definitions, exclusions, and relevant chapter or section notes.
- Verify the proposed code against current official HTSUS data and obtain customs-broker or classification-professional advice when the instrument has multiple functions or unusual technical features.
HTS heading 9030 summary
Oscilloscopes 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.

Common questions
What products fall under HTS heading 9030?
Oscilloscopes, spectrum analyzers and other instruments and apparatus for measuring or checking electrical quantities, excluding meters of heading 9028; instruments and apparatus for measuring or detecting alpha, beta, gamma, X-ray, cosmic or other ionizing radiations; 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.
