From 1 October 2026, every containerised sea shipment heading into the UAE has to be declared to the authorities before it is loaded at the last foreign port. Not before it arrives. Before it is loaded. The programme is called MPCI — Maritime Pre-Load Cargo Information — and the grace period ended on 30 September 2026.
If you run a forwarding desk in Dubai, Abu Dhabi or Sharjah, this changes who does what on every import consolidation, and how early. This article sets out who files, by when, what data is asked for, what goes wrong in practice, and a checklist you can send to your origin agents this week.
What MPCI is, and what it is not
MPCI is run by the National Advance Information Centre (NAIC), under the Federal Authority for Identity, Citizenship, Customs and Ports Security. It rests on UAE Cabinet Resolution No. 23 of 2023, which requires shipping lines and forwarders to submit bill of lading data electronically before loading at the last foreign port.
It is a security and risk pre-screen. NAIC looks at the shipment and decides whether it may be loaded at all. It is not a customs declaration and does not replace one. Your customs clearance on arrival still happens as before.
The programme launched in 2025. Its mandatory date was first set for 31 March 2026, was postponed, and became 1 October 2026.
What is in scope
According to NAIC’s own business specification, MPCI covers containerised sea cargo, both FCL and LCL, moving as:
- imports into the UAE;
- transshipment through UAE ports;
- transit through the UAE;
- freight remaining on board (FROB) — filed by the shipping line only.
Excluded for now: exports out of the UAE, non-containerised cargo (breakbulk, liquid bulk, Ro-Ro), empty containers, wooden vessels and crew’s effects. NAIC notes that some exclusions may be brought in later.
Who files what, and by when
MPCI follows the bill of lading hierarchy. Each layer is filed by the party that issued it:
- Shipping line, direct bill of lading: at least 24 hours before loading.
- Shipping line, master bill of lading: at least 6 hours before loading.
- Freight forwarder or sub co-loader, lowest-level house bill: at least 24 hours before loading.
- Master co-loader’s bill: at least 6 hours before loading.
The detail that catches forwarders out: the house bill deadline is earlier than the master bill deadline. Your shipping line has until six hours before loading; you have until twenty-four. On a consolidation, the line’s master bill carries your MPCI Party ID, so NAIC knows a house filing is expected. If it does not arrive, the master filing stalls.
To file, each forwarder registers on the NAIC portal and receives an MPCI Party ID. Shipping lines’ IDs are published on the portal; forwarders’ IDs are not, so you have to give yours to your shipping line and to any co-loader in the chain. Most filers submit through a technology service provider. NAIC itself charges no filing fee, though providers may.
Delegating to your origin agent
NAIC allows a UAE forwarder to delegate filing to an overseas forwarder. The overseas agent registers, receives its own Party ID, and files quoting yours as the liable party. This is often the cleanest arrangement, because the origin agent holds the shipper’s data in time. But delegation moves the work, not the responsibility. You stay liable, and you can see the filings and their status on the NAIC portal.
What data is asked for
NAIC’s mandatory data list includes, among others:
- bill of lading number and the MPCI Party IDs of the parties involved;
- cargo movement type (import, transit, transshipment or FROB);
- shipper and consignee name and address;
- port of loading, transshipment ports, port of discharge, place of receipt and place of delivery;
- container number, type and size, and seal number;
- goods description, package type and quantity, and goods weight;
- HS code for non-consolidated cargo — in practice, what each lowest-level house bill describes.
Vessel name, voyage, IMO number and estimated departure and arrival times are required on the shipping line’s bill.
The responses you will get back
Every filing is risk-assessed, and NAIC replies with one of these:
- ACT — assessment complete. You may load.
- ACW — assessment complete with comments. You may load, but read the comments.
- RFI — request for information. The cargo cannot proceed until you send the missing data or attachments (an invoice, packing list or certificate of origin, for example) and receive a fresh assessment.
- DNL — do not load. The shipping line must not load the shipment.
- PSF — pending sub-filing. Sent to the shipping line or master co-loader when a house bill has not been filed.
- EXP — filing expired, after 200 days without the required action.
The cascade matters. A DNL on one house bill cascades to the master bill, so one weak house filing can hold a whole consolidation. The way out is to remove that house bill and re-consolidate the rest under a new master. An RFI on a house bill keeps the master pending until it is answered.
What happens if you get it wrong
NAIC monitors four data-quality failures: missing filings, inaccurate data, late filings and invalid filings. The practical consequences are a Do Not Load instruction, cargo held, and fines. The fine amounts have not been published in any official material we could find. The National reported that enforcement is being introduced in phases, starting with formal communications and warning notices. Do not read that as permission: a DNL costs you a sailing whether or not a fine follows.
Where forwarders will actually trip
Vague goods descriptions
NAIC publishes examples of descriptions it will not accept. “Nuts” is unacceptable; “hexagonal aluminium bicycle nuts” is acceptable. “Auto parts”, “electronics” and “garments” are the kind of words that draw an RFI. So do numbers only, filler such as “AAA”, descriptions in a language other than English, and a house description that contradicts the master.
Missing or wrong HS codes
An origin agent who sends “HS: TBA” has given you nothing to file. A code that does not match the description is worse, because it looks complete.
Placeholder parties
NAIC wants the ultimate shipper and consignee, not the forwarder or consolidator. Filler values such as TBD, TBC, Unknown, “Same as above” or a phone number of zeros are rejected. For an import, the consignee’s address must be in the UAE.
Late house-bill data
This is the big one. Many origin agents still send house-bill details after the vessel sails, sometimes after arrival. That habit no longer works. If the data reaches you twelve hours before loading, you have already missed the 24-hour cut-off.
Rolled containers and split bills
When a container is rolled to another vessel, the filing has to be updated. NAIC accepts corrections and updates, but each update triggers a new assessment, and the first version must still be in before loading.
A checklist to send your origin agents this week
- Agree who files. Either you file every house bill, or you delegate to the agent. Write it down per trade lane.
- Exchange Party IDs. Give your MPCI Party ID to every agent and co-loader, and confirm your shipping lines have it.
- Move the internal cut-off. Ask for complete house-bill data at least 48 hours before loading, so you have a day to fix gaps before the 24-hour deadline.
- Insist on a real description: what the goods are, what they are made of and what they are used for. No generic words, no filler, English only.
- Insist on an HS code per line, and check that it matches the description.
- Insist on full parties: ultimate shipper and consignee, street address, city, country code, postal code and a working contact number.
- Send container and seal numbers as soon as the box is stuffed and sealed.
- Agree an RFI routine: who answers, how fast, and where the commercial invoice and packing list are kept so they can be attached within hours.
- Report rolls and splits the same day, so the filing is updated before the next vessel.
- Keep a log of each filing, its response code and the time it came back. If a DNL lands, you will want the history.
The data underneath
MPCI asks for nothing a well-run forwarding desk should not already hold. What it removes is the slack: data that used to be tidied up after sailing now has to be right a day before loading. Forwarders whose bookings carry clean, structured shipment data from the start will find the filing — whoever submits it — is a copy, not a scramble.
