Heading 8512 covers lighting equipment specifically designed for use on bicycles or motor vehicles, while heading 8513 covers portable lamps designed to function independently of any vehicle — such as handheld flashlights, headlamps worn by a person, or camping lanterns. A lamp sold and designed as a bicycle light is classified under 8512 even if it can be detached and used handheld; the intended design use governs classification.

Section 301 tariffs on Chinese-origin portable lamps have accelerated sourcing shifts toward Vietnam, Thailand, and Cambodia, all of which appear among the top suppliers under this heading. However, CBP scrutiny of transshipment — where goods are routed through third countries to avoid China-origin duties — has intensified, and importers must ensure that country-of-origin determinations are based on where substantial transformation occurs, not merely where goods are shipped from.
