Approved establishment list updated for Bhutan; customs instruction partially modified and officers must implement unchanged certification requirements. An agreement implementation updates the approved Bhutanese establishments list for imports while confirming that the format of the Health Certificate and the list of authorized signatories remain unchanged; existing import compliance requirements continue to apply. The instruction partially modifies the earlier customs circular to incorporate the updated list and directs officials to sensitize subordinate officers, with a request to report any implementation difficulties to the Board.
