Sec. 1502. Regulations for appraisement and classification


(a) Powers of Secretary of the Treasury

    The Secretary of the Treasury shall establish and promulgate such 
rules and regulations not inconsistent with the law (including 
regulations establishing procedures for the issuance of binding rulings 
prior to the entry of the merchandise concerned), and may disseminate 
such information as may be necessary to secure a just, impartial, and 
uniform appraisement of imported merchandise and the classification and 
assessment of duties thereon at the various ports of entry. The 
Secretary may direct any customs officer to go from one port of entry to 
another for the purpose of appraising or classifying or assisting in 
appraising or classifying merchandise imported at any port, and may 
direct any customs officer at any port to review entries of merchandise 
filed at any other port.

(b) Duties of customs officers

    It shall be the duty of all officers of the customs to execute and 
carry into effect all instructions of the Secretary of the Treasury 
relative to the execution of the revenue laws; and in case any 
difficulty arises as to the true construction or meaning of any part of 
the revenue laws, the decision of the Secretary shall be binding upon 
all officers of the customs.

collection district, was contained in R.S. Sec. 2947. Prior provisions 
requiring the Secretary to establish rules and regulations to secure a 
just, faithful, and impartial appraisal, just and proper entries, and to 
report such rules and regulations to the next session of Congress, were 
contained in R.S. Sec. 2949. Both of these sections were repealed by act 
Sept. 21, 1922, ch. 356, title IV, Sec. 642, 42 Stat. 989.

decision of the Board of General Appraisers, were contained in act Mar. 
3, 1875, ch. 136, Sec. 2, 18 Stat. 469, prior to repeal by act Sept. 21, 
1922, ch. 356, title IV, Sec. 643, 42 Stat. 989.
