Dangerous goods by mode: IMDG, ADR, RID and IATA One cargo, four rulebooks. Change the mode, change the rule.
Dangerous goods are subject to a separate international rule in each mode of transport: the IMDG Code at sea, ADR by road, RID by rail, and in the air the ICAO Technical Instructions and the IATA DGR based on them. Türkiye also has a regulation for each mode, placing obligations on senders, receivers, loaders and sometimes the forwarder. By road, any business that sent or received 20 tonnes or more of dangerous goods in the last calendar year must hold a Dangerous Goods Activity Certificate. In the air, the 30% state-of-charge limit for lithium-ion batteries has applied since 2026 to batteries packed with equipment as well.
Four modes, four rules
| Mode | International rule | Edition in force | Turkish regulation |
|---|---|---|---|
| Sea | IMDG Code (IMO) | Amendment 42-24: mandatory from 1 January 2026, voluntary in 2025 (MSC.556(108)) | Regulation on the Carriage of Dangerous Cargo by Sea and Cargo Securing (Official Gazette 14.11.2021) |
| Road | ADR (Türkiye acceded on 22 February 2010) | ADR 2025: the previous edition could be used until 30 June 2025 (ADR 1.6.1.1) | Regulation on the Carriage of Dangerous Goods by Road (Official Gazette 18.06.2022) |
| Rail | RID (OTIF, COTIF Appendix C) | RID 2025: from 1 January 2025 | Regulation on the Carriage of Dangerous Goods by Rail (Official Gazette 16.07.2015) |
| Air | ICAO Technical Instructions (Doc 9284); IATA DGR | TI 2025–2026; IATA DGR 67th edition, 1 January 2026 | SHT-18, Instruction on the Safe Transport of Dangerous Goods by Air (Turkish Civil Aviation Authority, 04.06.2025) |
Turkish translations of ADR 2025 and RID 2025 are published on the website of the Directorate General for Regulation of Transport Services. The IATA DGR is published in a new edition every year. When a shipment uses more than one mode, the rule of each leg applies separately: a consignment for air transport must also comply with the rules of the road, sea or rail leg to the airport (SHT-18 art. 29).
Road: the activity certificate
The Turkish road regulation requires businesses in the transport chain to hold a Dangerous Goods Activity Certificate (TMFB) (art. 7):
- Carriers and tank-container operators, regardless of quantity.
- Businesses that received or sent 20 tonnes or more of dangerous goods in the last calendar year; also packers, loaders, fillers and unloaders above that threshold.
- Businesses dealing with Class 1 (except 1.4S) and Class 7 (except those under ADR 1.7.1), regardless of quantity.
For receivers and unloaders, activities under the ADR 3.3, 3.4 and 3.5 exemptions are not counted towards the quantity (art. 7/2). Under the regulation, where the carriage is based on a contract, the person named as "consignor" in the contract is the consignor (art. 4). So if a forwarder is named as consignor, the consignor's obligations fall on it.
Sea: cargo interests and the packing certificate
In the Turkish sea regulation, the "cargo interest" is the consignor, receiver or agent of the dangerous cargo or the freight forwarder (art. 4/1-v). The cargo interest (art. 9):
- prepares the mandatory documents and makes sure they travel with the cargo,
- ensures the cargo is correctly classified, packed, marked, labelled and placarded,
- ensures safe loading, stowage and securing into approved packagings and cargo transport units.
The IMDG Code's Container/Vehicle Packing Certificate is completed and signed by the person who loads the cargo into the container and who has received IMDG 1.3 training; it is presented to the port before or together with the cargo, and a copy is placed on the inside wall of the container's right-hand door (art. 15/4). UN-certified packagings are mandatory (art. 15/3). When IMO rules change, the current IMO provisions apply (art. 24/4).
Air and lithium batteries
SHT-18 is based on the ICAO Technical Instructions; unless otherwise provided, the transport document is prepared at least in English (art. 30). For lithium-ion batteries, IATA's 2026 guidance sets the state-of-charge (SoC) limit as follows:
| How it is shipped | Packing instruction | 30% SoC limit |
|---|---|---|
| Battery on its own | PI 965 (UN 3480) | Mandatory; above it only with approval of the State of Origin and the State of the Operator |
| Packed with equipment | PI 966 (UN 3481) | Mandatory from 1 January 2026: all batteries in Section I, batteries above 2.7 Wh in Section II |
| Contained in equipment | PI 967 (UN 3481) | Not mandatory, strongly recommended (30%, or 25% indicated capacity) |
Safety data sheet
The supplier of a substance or mixture classified as hazardous must give the recipient a safety data sheet (SDS) prepared by a certified chemical assessment expert (Turkish KKDİK Regulation art. 27). Section 14 of the sheet is transport information: the UN number, the UN proper shipping name and the transport hazard class are given there. It is the first place to look to find out whether a cargo is dangerous goods.
When it goes wrong
The forwarder is named as consignor in the contract
Under the road regulation, the person named as "consignor" in the contract is the consignor, and the obligations pass to them. At sea, the forwarder is already within the definition of "cargo interest". Settle from the start who is named in which capacity.
The packing certificate is signed by someone untrained
The certificate is presented to the port before or together with the cargo; a signature by someone without the training, or a copy missing from the door, is contrary to the regulation.
A battery-powered product is sent by air fully charged
For lithium-ion batteries packed with equipment, the 30% limit has been mandatory since 2026. In Section I, anything above it may be carried only with the written approval of the State of Origin and the State of the Operator.
Documents prepared to an old edition
At sea, amendment 42-24 has been mandatory since 1 January 2026; by road, the transition period for the old ADR ended on 30 June 2025. Check document and label templates against the current edition.
Frequently asked
How do I know whether my cargo is dangerous goods?
Ask your supplier for the safety data sheet and look at section 14. If it gives a UN number and a transport hazard class, the cargo is carried as dangerous goods.
Can cargo prepared under ADR go by ship or plane as well?
Not automatically. Each mode has its own rule; the IMDG Code applies to the sea leg and the ICAO Technical Instructions to the air leg. Cargo going by air must also comply with ADR on the road leg to the airport (SHT-18 art. 29).
I send less than 20 tonnes a year. Do I need the activity certificate?
By road, as a consignor below the threshold you generally do not, but for Class 1 (except 1.4S) and Class 7 quantity does not matter. The threshold is calculated separately for packing, loading and filling (art. 7/1).
Does the forwarder have responsibilities for dangerous cargo?
At sea, yes: the regulation counts the freight forwarder as a "cargo interest" (art. 4/1-v) and gives the cargo interest duties on documents, classification and loading (art. 9). For the sender's duty to inform the forwarder of dangerous cargo in writing, see the forwarder in Turkish law.
