This heading is specific to apparatus whose primary function is recording audio — capturing sound to a medium. The residual heading (76339) covers apparatus for recording or reproducing where no more specific heading applies. When a device is clearly designed and marketed as a recorder first, this heading takes precedence; ambiguous multi-function devices may require a binding ruling.

From a customs classification standpoint, both fall within this heading regardless of grade or intended end-use. However, professional units may carry higher declared values, affecting duty calculations, and wireless-enabled professional recorders must meet FCC equipment authorization requirements just as consumer units do. Some professional equipment may also be eligible for duty treatment under specific tariff provisions — a customs broker can advise on applicable options.
