What is a SAD (Single Administrative Document) in EU customs?
A Single Administrative Document (SAD) is the standard EU customs declaration form used for import, export, and transit shipments.

A Single Administrative Document (SAD), known as Form C88 in the UK, is the standard customs declaration form used across the EU, Switzerland, Norway, Iceland, Turkey, North Macedonia, and Serbia for import, export, and transit movements. Carriers, forwarders, or customs brokers submit it to declare goods, HS codes, values, and the customs procedure applied.
What information does a SAD (Single Administrative Document) contain?
The SAD is built around a set of numbered boxes that together describe the shipment, the parties, and the customs procedure requested. Core fields include the consignor and consignee, the country of origin and destination, the Harmonised System (HS) commodity code, the customs value, the gross and net weight, the transport mode, and the specific procedure code (import for free circulation, export, or transit). Under EU law, the exact data elements a declaration must carry are set out in Annex B of Implementing Regulation (EU) 2015/2447 , which lists every field customs authorities can require. The paper SAD was historically an eight-copy set, with copies retained at export, accompanying transit goods, or returned as proof of exit. Most declarations are now filed electronically, but the SAD data structure still defines what those electronic forms capture, as confirmed on the European Commission's Single Administrative Document page .
Who has to submit the SAD, and does a truck driver need a copy on board?
The legal obligation to lodge the SAD sits with the declarant, which is usually the exporter, importer, or a customs broker or freight forwarder acting as an authorised representative. A truck driver is not normally the one filing the declaration, but the vehicle should carry proof that a declaration exists, typically a Movement Reference Number (MRN) or an accompanying document that customs officers can check at the border or during a roadside inspection. Fleets that automate declaration handling through a transport management system reduce the risk of a driver being held at the border with incomplete paperwork; a TMS built for cross-border freight can pull shipment data straight into the declaration rather than re-keying it manually.
SAD vs T1 transit document vs CMR note: what is the difference?
Road freight operators often confuse the SAD with the other documents travelling alongside a shipment. Each serves a distinct legal purpose, and one movement can require more than one of them, as explained in the Logifie guide to the T1 transit document .
| Document | What it's for |
|---|---|
| SAD (Single Administrative Document) | the general customs declaration for import, export, or transit |
| T1 transit document | moves non-EU goods under customs suspension between EU points |
| CMR consignment note | the road transport contract between shipper and carrier, not a customs form |
| ATA carnet | temporary duty-free admission of goods or equipment, replacing a SAD for that specific movement |
Goods held under transit or stored in a customs facility before final clearance raise the same disambiguation problem; the Logifie explainer on bonded warehouses covers how that storage status interacts with the eventual SAD filing.
In 2026 the SAD remains the mandatory default declaration form even as the EU's Single Window Environment for Customs, established by Regulation (EU) 2022/2399 and applicable since 2022-12-12, phases in system-to-system data exchange between customs and partner authorities. Full Member State connection to the EU CSW-CERTEX platform is required by 2031-12-13, so the underlying paperwork is digitising gradually rather than disappearing.
Frequently asked questions
Is the SAD the same as Form C88?
Yes. Form C88 is simply the UK's historical name for the SAD, carried over from before Brexit and still used informally in British customs and freight-forwarding practice. The underlying data fields and legal function are the same document recognised across the EU and EFTA states.
Do I need a SAD for goods moving between two EU member states?
No. Goods moving freely between two EU member states are in free circulation and do not require a SAD, since no customs border is crossed. A SAD is only needed when goods enter, leave, or transit the EU customs territory, or move to or from a non-EU country such as the UK, Switzerland, or Turkey.
How many copies does a SAD have, and what is each copy for?
The traditional paper SAD was an eight-copy set, with copies retained by the exporting country, accompanying the goods during transit, and returned as proof that the goods left the customs territory. Most declarations today are lodged electronically, so the copy structure now maps to data messages exchanged between customs systems rather than physical carbon-copy sheets.
Who is legally responsible for the accuracy of the SAD, the exporter, forwarder, or carrier?
The declarant named on the SAD is legally responsible for the accuracy of the information submitted, and that role is usually filled by the exporter, importer, or the customs broker or forwarder acting on their behalf. A carrier transporting the goods is generally not the declarant, but incorrect data can still delay the vehicle at the border, which is why accurate handover of shipment details to the declarant matters.
