Centralized examination station (CES): who pays
A centralized examination station is a privately operated facility, not staffed by Customs officers, where merchandise is made available for physical examination. The entry filer names which CES the box goes to, the operator bills the user from a fee schedule the port director approved, and nothing about an exam stops the terminal's storage clock or the carrier's detention.
- Centralized examination station
- A privately operated facility, not in the charge of a Customs officer, at which merchandise is made available to Customs officers for physical examination. US CES operators are selected by the port director under 19 CFR part 118 and bill users directly from an approved fee schedule.
Every import desk knows the sentence “the container has been selected for an exam”, and almost none of them know who is holding the box, who chose that party, or what the bill will say. All three answers are in the regulations, and the first one is the surprise.
It is a private business, not a customs shed
19 CFR § 118.1 is unambiguous about what a CES is:
A centralized examination station (CES) is a privately operated facility, not in the charge of a Customs officer, at which merchandise is made available to Customs officers for physical examination.
The operator applies to the port director, signs an agreement that runs three to five years under § 118.3, posts a custodial bond, and makes its money by charging the people whose cargo it handles. CBP’s officer turns up to look. Everything around that visit, the lift, the move, the de-vanning, the space and the re-stuffing, is a commercial service with an invoice attached.
You designate it. Probably without knowing
The part worth reading twice is in § 151.15(a). The authorisation to transfer the box
will act as notification and authorization to the entry filer that the merchandise must be transferred to the importer-designated CES unless another CES is designated by the port director
Importer-designated. Where there is more than one station at a port, the choice of which one, with its own fee schedule, its own equipment and its own queue, belongs to the importer and is exercised in practice by whoever files the entry. A desk that has never asked its broker which CES it nominates has delegated a cost decision it does not know exists.
Two bills, from two directions
The station bills you directly. § 118.4(c) requires the operator to “assess service fees as outlined in the fee schedule included in the approved application … and bill users directly for services rendered”.
Then the regulations add the importer’s own costs on top. § 151.6: “the importer shall bear any expense involved in preparing the merchandise for Customs examination and in the closing of packages”. And § 151.7(c), when the examination happens outside port limits, makes the importer pay “actual expenses of travel and subsistence but not the salary during regular hours of duty of the examining officer”.
The one thing a CES fee is that demurrage is not: published in advance
This is the useful asymmetry. A CES cannot change its prices on you. Under § 118.5 the operator must give the port director 90 calendar days advance written notice of any change with a justification, the public is invited to comment, and the operator “shall remain bound by the existing fee schedule” until the port director approves in writing. The schedule itself has to be “comparable to fees charged for similar services in the area to be served by the CES” under § 118.11(c).
So the exam cost is knowable before the box ships, in the same way the container freight station rate is knowable in India and for the same reason: somebody made the custodian publish it. The charges that run alongside it are not.
Nothing about an exam pauses the clocks
An exam is a customs process. Demurrage is the terminal’s charge for its space and detention is the carrier’s charge for its box, and neither is suspended because a government agency asked to look inside. Meanwhile § 118.4(b) requires the station to serve cargo “on a ‘first come-first served’ basis”, which is fair and is also a queue nobody shows you.
That is the shape of the whole problem. The days are being counted by parties who are not talking to each other: the terminal on its tariff, the carrier on its free time, the station on its schedule, and the desk finding out afterwards from three invoices. What a desk can control is the one input that decides whether the box was ever going to clear in time: a complete, checked document pack, days early rather than hours late. That is what demurrage and detention software that counts the exam days is for: not stopping the exam, but making sure the exam is the only thing the shipment is waiting on.
Questions traders ask
What is a centralized examination station?
19 CFR 118.1 defines it as a privately operated facility, not in the charge of a Customs officer, at which merchandise is made available to Customs officers for physical examination. It is not a Customs building and not part of the terminal: it is a business that holds an agreement with CBP, runs for three to five years under 19 CFR 118.3, and is paid by the people whose cargo it handles.
Who chooses which CES my container goes to?
You do, through your entry filer, unless the port director overrides it. 19 CFR 151.15(a) says the authorisation acts as notice that the merchandise must be transferred to the importer-designated CES unless another CES is designated by the port director. Most desks never learn they made a choice, because the broker makes it on their behalf and the fee schedules differ.
Who pays for a customs exam?
The importer, in two separate directions. The CES operator assesses service fees from its approved schedule and bills users directly under 19 CFR 118.4(c). On top of that, 19 CFR 151.6 puts the cost of preparing the merchandise for examination and closing the packages on the importer, and 19 CFR 151.7(c) adds travel and subsistence for the officer when the place of examination is outside port limits. The officer's salary during regular hours is not charged.
Does a customs exam stop demurrage?
Not by itself. The exam is a customs process; demurrage and detention are contractual charges on the terminal's space and the carrier's box, and neither stops because a government agency has asked to look inside. Service at the CES is on a first come first served basis under 19 CFR 118.4(b), so a queue you cannot see adds days to charges that are still running. Whether a particular charge is reasonable in those circumstances is a separate question under the Federal Maritime Commission's interpretive rule.
How much does a CES charge?
Whatever its approved schedule says, which varies by station. The fees in the schedule must be comparable to fees charged for similar services in the area the CES serves under 19 CFR 118.11(c), and an operator that wants to change them gives the port director 90 calendar days advance written notice with a justification, after which the public comments and the port director decides. So the rate is set in advance and askable, which is the opposite of how a demurrage charge arrives.
Is a CES the same as a container freight station?
They are the same idea in two legal systems and they are not interchangeable terms. A CES is a US facility designated under 19 CFR part 118 for CBP examination. A container freight station is the Indian equivalent of an off-dock customs area where boxes are de-stuffed and cleared, where the operator is a Customs Cargo Service Provider under the Handling of Cargo in Customs Areas Regulations 2009 and must publish its schedule of charges. Both start a storage clock of their own.
