8519.81 - Using magnetic, optical or semiconductor media:

HTS code 8519.81 encompasses sound recording and reproducing apparatus that utilize magnetic, optical, or semiconductor media for data storage. This category specifically includes devices where sound is stored and/or played back using technologies such as magnetic tapes, CDs, DVDs, Blu-rays, or flash memory. Examples within this classification would include portable digital music players, CD players, and devices that record audio onto these media types.

This category is distinct from its sibling, 8519.89, which covers "Other" sound recording or reproducing apparatus that do not rely on magnetic, optical, or semiconductor media. This implies that 8519.89 would likely include older technologies or less common methods of sound storage and playback not fitting the specified media types of 8519.81.

Within 8519.81, a further subdivision exists to differentiate between apparatus that are solely for sound reproduction and other types. The subcategory 8519.81.41, "Other," indicates that this primary classification for media-based sound apparatus is further refined to distinguish between devices capable of both recording and reproducing sound versus those that exclusively reproduce sound. This distinction is crucial for accurate duty assessment and trade statistics.
