Why is UPS waiting for customs info on a domestic package?

[WebEarp]

UPS hasn't contacted me. I don't know what this means... It appears to be waiting for customs information, but it wasn't imported. It was just shipped from California to Utah

There are three basic reasons your shipment could get stuck in customs: ...
Sometimes, *customs clearance documentation is incomplete, causing delays
while customs coordinates with the shipper to gather needed information*.
You may owe taxes on the shipment, which will be released when you pay them.27

Hi @WebEarp!

Have you managed to get in touch with UPS to clarify the delivery status of your package? 

Since we won't have access to any more tracking information than you do here, I would definitely be interested to confirm any necessary next steps with their team directly.
