8543.70.71.00 - Electric luminescent lamps 🖩

This classification covers electric luminescent lamps, which are devices that produce light through electroluminescence. This phenomenon involves the emission of light by a material when an electric current is passed through it. Examples within this category include electroluminescent panels, strips, and individual diodes that function as light sources. These are distinct from other electrical equipment that may produce light as a byproduct, but where light emission is not the primary function.

When classifying within heading 8543, it is crucial to differentiate electric luminescent lamps from sibling categories. For instance, while physical vapor deposition apparatus (8543.70.20.00) and articles for connecting to telecommunication networks (8543.70.60.00) fall under the broader umbrella of "other machines and apparatus," they serve entirely different functional purposes and possess distinct technical characteristics. Electric luminescent lamps are specifically designed for illumination through electroluminescence, unlike the manufacturing or communication-related functions of these other items.

As this HTS code represents a leaf node, there are no further subcategories to introduce. Therefore, classification hinges on accurately identifying the product as an electric luminescent lamp based on its principle of operation and intended use as a light source. The key determining factor is whether the article utilizes electroluminescence for light generation, thereby falling under this specific designation rather than other electrical lighting equipment covered elsewhere in the tariff schedule.
