HTS heading 8539 is a broad product category for electric light sources and certain related parts. It groups together filament lamps, discharge lamps, sealed-beam lamp units, ultraviolet and infrared lamps, arc lamps, and LED light sources. The heading covers the light-producing unit itself, not every complete lighting fixture that happens to contain one.
To reach a specific 8-digit HTSUS code, first identify the lamp’s operating technology and principal characteristics. Subheadings may distinguish products by type, construction, intended function, or other technical features—not simply by material. Confirm whether the item is a separate lamp, a sealed-beam unit, an LED light source, or a part, then use the applicable subheading descriptions and legal notes to narrow the classification. A customs broker or classification specialist may be needed when the product combines multiple functions or does not clearly match the wording.
What to check
- Identify how the product produces light: filament, gas discharge, arc, LED, ultraviolet, infrared, or another technology.
- Check whether the item is a replaceable light source, a sealed-beam lamp unit, a complete lighting fixture, or a part; do not classify the entire fixture solely by its included bulb.
- Record technical details such as voltage, wattage, lamp base, bulb construction, LED package or module design, and whether control electronics are built in.
- Compare the product’s specifications and photographs with every relevant 8-digit subheading and its legal notes, rather than choosing by a marketing name alone.
- Keep product literature, test data, invoices, and component information that support the selected classification, and ask a customs professional to review uncertain or multifunction products.

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.
