The C&ED is an active member of the World Customs Organization (WCO) and Asia Pacific Economic Cooperation (APEC).
At the working level, the department and the China Customs have each established designated liaison officers to facilitate the exchange of intelligence through direct telephone hotlines.
Officers working for HM Revenue and Customs (HMRC) and the UK Border Force collect a range of taxes and duties, control imported and exported goods, and prevent banned items from entering or leaving the United Kingdom.
[11] Officers may ask questions with respect to the baggage of people entering or leaving the United Kingdom and any thing contained therein or carried with them.
[12] Since the amendments to CEMA 1979 inserted by the Policing and Crime Act 2009 Officers may also require a person entering or leaving the United Kingdom to produce a Passport (or National ID Card when that may be used as an alternative) and answer questions about their journey.
[14] An officer may board or enter any ship, aircraft, vehicle, house or place and take such steps as are reasonably necessary to stop or prevent the sending of a signal or message connected with smuggling.
[19] Officers may ask any person entering or leaving a free trade zone (as designated by the Treasury) questions with respect to any goods.
[20] Officers may board a vehicle at any time while it is entering or leaving a free trade zone search any part of it.
[21] If an officer has reasonable grounds to suspect that any secret pipe or other means of conveyance, cock, vessel or utensil is kept or used by a distiller, rectifier, compounder, registered brewer, producer of wine, producer of made-wine and maker of cider, that officer may, at any time, break open any part of the premises of that trader and forcibly enter them and so far as is reasonably necessary break up the ground in or adjoining those premises or any wall thereof to search for that pipe or other means of conveyance, cock, vessel or utensil.
[23] If they believe serious fraud is occurring in connection with such gaming, they may obtain a court warrant to enter the premises using reasonable force.
[25] They may also seize all the tackle, apparel or furniture in any ship, aircraft, vehicle or animal that has become liable to forfeiture under the customs and excise Acts.
[32] If an officer has reasonable grounds to suspect that is carrying any article which is chargeable with any duty which has not been paid or secured or (if being imported or exported) of which any prohibition or restriction is in force, they may detain them and search them.
Among their many functions are detecting and confiscating contraband, making sure that import duties are paid, and preventing those without legal authorization from entering the United States.
In the past, American customs officers were part of the Department of the Treasury, the oldest law enforcement agency in the U.S., dating back to 1789.
