Customs Rulings Online Search System (CROSS) : CROSS is a
searchable database of CBP rulings that can be retrieved based on
simple or complex search characteristics using keywords and Boolean
operators. CROSS has the added functionality of CROSS referencing
rulings from the initial search result set with their modified, revoked
or referenced counterparts. Rulings collections are separated into
Headquarters and New York and span the years 1989 to present.
Collections can be searched individually or collectively. This system
is good for investigating the issues such as the differences between
loungewear and the possible
differences between undershirts & t-shirts, etc.
If you have serious questions, you should consult with a
customs attorney for clarity.
