To amend the Homeland Security Act of 2002 relating to authority of U.S. Customs and Border Protection to consolidate, modify, or reorganize Customs revenue functions.

This bill amends the Homeland Security Act to clarify and expand U.S. Customs and Border Protection's (CBP) authority over customs revenue operations. It requires CBP to maintain staffing levels above a specified "optimal" threshold from a 1978 model before reducing staff, and adds new job titles like "National Account Managers" to existing categories. The bill explicitly authorizes CBP to consolidate, modify, or reorganize revenue functions - such as by adjusting job classifications or creating new positions - and allows the Office of Personnel Management to establish standards for new roles. This directly affects CBP's internal staffing structure and job classifications but does not change customs duties or tax collection policies.
