      The collectors and other officers of the customs shall pay due
    regard to the inspection laws of the States in which they may
    respectively act, in such manner that no vessel having on board
    goods liable to inspection shall be cleared until the master, or
    other proper person, shall have produced such certificate that all
    such goods have been duly inspected, as the laws of the respective
    States may require to be produced to collectors or other officers
    of the customs.
