The heading excludes lighting equipment used for motor vehicles (classified under 8512). If a rechargeable work light is principally designed as a portable, self-powered lamp and vehicle mounting is incidental, it may remain in 8513. If it is specifically designed and marketed for vehicle use, 8512 applies. Dual-use products should be evaluated against the principal-use standard, and a binding ruling is advisable.

When batteries are imported together with a flashlight as a retail set, they are generally classified with the flashlight under 8513 as a set. If batteries are imported separately, they fall under the electric accumulators or primary cells headings. Importers should confirm retail-set treatment with CBP when the battery value is significant relative to the lamp.
