CBP Form 300 - Bonded Warehouse Proprietor's Submission Mobile App
"The CBP Form 300 - Bonded Warehouse Proprietor's Submission mobile app was designed to simply the warehouse entry process.
How does it work?
Instead of filling out paper versions of custom form 30, the person in charge of warehouse entry or the dutiable contents owner can fill out the required fields electronically using a smartphone or tablet.
This helpful app was designed for those who sell and store duty-free merchandise, merchandise that requires a special license and other import materials that require a manifest form. Using the electronic custom bond form helps reduce clerical errors and simplifies the bonded warehouse proprietor's submission process."
