To any musicians planning on traveling through U.S. Customs in the future, a travel advisory has been issued for the protection of your instruments in particular.
The U.S. Customs does not respect the value of your instrument either as a piece of workmanship or as the tool with with you can create your music with. To them it is a suspicious item that may be taken apart completely without your consent for the safety of the country.
There is a possibility that you are hiding dangerous objects within the center of the instrument or possibly using a glue that is going to spread the corona virus or possibly made out of a wood that will instantly destroy the precious ecoculture of the nation which the United States values very highly, and would never do anything to harm.
Incidents sparking this travel advisory include the destruction of 11 rare flutes, due to their exotic plant pathogens, a piano destroyed because its glue smelled funny and most recently, the West African kora instrument taken apart during its time at customs, no reason given.
As musicians know, instruments are not all created equal, and depending on the type and craft of your own personal instrument it can range from important to priceless to you. So, please take care if you choose to travel to the U.S. that you do not bring any instrument of value to you, because it will not be treated with the respect it deserves.
Travel at your own risk.
