An acoustic guitar with a built-in pickup or preamp is still primarily a string instrument and classifies under 920290. A fully electric guitar that relies entirely on electronic amplification to produce its sound may be assessed differently, but most acoustic-electric hybrids remain under 9202 because the string vibration is the principal sound-producing mechanism.

Yes — certain tonewoods historically used in bowed instruments, such as Brazilian rosewood (Dalbergia nigra) for fittings or bows, are CITES Appendix I species requiring permits. Other rosewoods and ebonies fall under Appendix II. Importers of fine bowed instruments should verify the species of all wood components and obtain the necessary CITES documentation before shipment.
