8545.90.20.00 - Arc light carbons 🖩

This HTS category, 8545.90.20.00, specifically covers arc light carbons. These are carbon rods designed for use in arc lighting systems, such as those found in searchlights, projectors, and industrial lighting applications. The electrical current passing through these carbons creates an intense light arc, generating significant heat and illumination. The material is typically graphite, which possesses excellent conductivity and high sublimation points required for this application.

While the parent category 8545.90 broadly encompasses "Other" articles of graphite or carbon for electrical purposes, this subcategory narrows the focus to a very specific application: arc light carbons. It is important to distinguish this from other "Other" categories at the same level. For instance, 8545.90.40.00 would likely cover other electrical carbon articles not specifically enumerated elsewhere, such as carbon blocks for resistance heating or specific components not directly related to light generation through an arc. The key differentiator for 8545.90.20.00 is the direct use of the carbon rod as an electrode to sustain an electric arc for illumination.

As this is a leaf node within the HTS structure, there are no further subcategories. The classification is considered definitive for arc light carbons. When classifying, focus on the physical form of the carbon rod and its intended use in creating an electric arc for light production. The presence of any metal components would be incidental and not change the classification as long as the primary function remains arc lighting.
