Dangerous goods training is a legal condition of handling the cargo, not a courtesy to your customer. Under IATA's rules for air, the IMDG Code for sea and the US Hazardous Materials Regulations (49 CFR), the people in a forwarder's office who classify, document, accept or sign for dangerous goods must be trained for the function they actually perform, and that training must be refreshed and recorded. For air freight the refresher cycle is 24 months; for US hazmat employees it is three years; the IMDG Code asks for periodic refreshers without a number I could confirm in its public text. This guide sets out who needs training, how often, what records an auditor will ask for, and a practical booking-desk control that keeps untrained staff from accepting dangerous goods by accident. The classes, paperwork and packing rules themselves are covered in our guides to dangerous goods classes and the dangerous goods declaration.
Does a freight forwarder need dangerous goods training?
Yes, if anyone in the business touches dangerous goods in any of the ways the regulations list, and that includes people who only process what looks like ordinary cargo. IATA's own training guidance (Dangerous Goods Training Guidance, Edition 1, dated 1 January 2023) names freight forwarders directly in several of its job functions: preparing dangerous goods consignments, processing or accepting goods presented as general cargo, and processing or accepting declared dangerous goods consignments. The second one matters most for small forwarders. Its stated purpose is preventing undeclared dangerous goods from being accepted into air transport, so a booking clerk who never handles a declared DG shipment still needs training to recognise the ones nobody declared.
The US rule is written around the same idea. 49 CFR 171.8 defines a hazmat employee as someone employed full-time, part-time or temporarily who directly affects hazardous materials transportation safety, and the definition expressly includes a person who loads, unloads or handles hazardous materials, prepares them for transportation, or is responsible for the safety of transporting them. Whether a salesperson who only quotes is covered depends on whether their work directly affects transport safety, so many forwarders simply train everyone who can accept a booking or release a document.
Are you "the shipper" if you sign the declaration?
This is the common misconception, and it cuts both ways. Forwarders often say "the shipper is responsible for the declaration, we just pass it on." Regulators do not look at titles; they look at functions. The US definition of an offeror in 49 CFR 171.8 covers any person who performs, or is responsible for performing, a pre-transportation function, or who tenders the material to a carrier. 49 CFR 171.2(b) adds that there can be more than one offeror of a shipment, that each is responsible for the functions it performs, and that an offeror may rely on information from another offeror unless it knows, or a reasonable person would know, that the information is wrong.
In practice that means: if your staff classify the goods, choose the packaging, mark and label packages, complete the declaration or sign the certification that goes with it (49 CFR 172.204 sets the wording of that certification), they are performing the shipper's functions and need the shipper's training. If you only book and move a package that a trained shipper declared, your duty is narrower, but it still includes spotting a declaration that cannot be right. IATA's guidance trains forwarder staff to check, not just to forward.
Training requirements by mode
The three frameworks share a skeleton (general familiarisation, function-specific training, safety training, security awareness) but differ in cycle and record rules. As of 6 October 2026:
| Framework | What the rule requires | Refresher interval | Records |
|---|---|---|---|
| Air: IATA DGR (based on ICAO Technical Instructions) | Competency-based training and assessment for each function (DGR subsection 1.5): familiarisation, function-specific and safety training, with an assessment that shows the person is competent | Within 24 months of the previous training; completing it in the last 3 months of validity keeps the original cycle | Employer keeps training and assessment records at least 36 months from the most recent completion month |
| Sea: IMDG Code chapter 1.3 | Shore-side staff trained in the dangerous goods provisions in a way that matches their responsibilities, plus security training where chapter 1.4 applies | "Periodically supplemented with refresher training" to reflect regulatory change; no fixed number confirmed here | Keep records; check the wording of the edition you operate under |
| US: 49 CFR 172.704 | General awareness, function-specific, safety and security awareness training; in-depth security training where a security plan applies | At least once every three years | Record for each hazmat employee, kept while employed and for 90 days after, covering the preceding three years |
Two details are easy to miss. First, IATA and ICAO moved from the old numbered categories (the "category 6" style of certificate) to function-based, competency-based training, and IATA's guidance dates its first edition 1 January 2023. A certificate should now describe the function it covers and the materials used, not just a category number. Second, the DGR is republished every year. IATA lists the 68th edition for 1 January 2027, so your refresher should teach the edition you will be shipping under, and the training date does not excuse you from the changes that follow it.
How the air rules work: functions, not job titles
IATA's guidance states that responsibilities come from the functions a person performs and not from their job title. It also says people in smaller companies often perform tasks across several functions, in which case their training has to cover all of them. For a forwarder this is the usual case: the same operator takes the booking, checks the paperwork and releases the document set.
The guidance also lets preparation training be tailored: a person who only packs, marks and labels may be trained only on those tasks, and training may be limited to the classes or UN numbers the company actually prepares. That is a real saving for a forwarder that ships, say, only Class 9 batteries and paint, but it creates a duty in the other direction. If you tailor the scope, the system has to stop that person from accepting anything outside it. Your booking process, not their memory, is what enforces the limit.
Gaps in work also matter. IATA's guidance suggests that after an absence from the function of more than three months the employer should brief the person on regulatory changes, and after more than twelve months should add a practical assessment such as an on-the-job session or simulation. These are suggestions, not rules, but they are a sensible internal policy for staff returning from leave.
US forwarders: 49 CFR 172.704 in practice
For a US employer the text of 49 CFR 172.704 is short and worth reading in full. The points that catch forwarders out:
- Training before work, or supervision. A new hazmat employee, or one who changes job functions, may perform the function before training is complete only under the direct supervision of a properly trained and knowledgeable hazmat employee, and the training must be finished within 90 days of starting or changing function.
- Training and testing. The record must certify that the person has been trained and tested, not only that they attended.
- Air or sea training can count. 172.704(a)(2)(ii) allows function-specific training on the ICAO Technical Instructions or the IMDG Code to stand in for HMR function-specific training, to the extent it covers the functions authorised by 49 CFR part 171 subpart C. A forwarder that moves US exports by air usually runs one IATA-based cycle and adds the US-specific parts.
- The employer is responsible regardless. 172.704(c)(4) says the hazmat employer is responsible for compliance with the whole subchapter whether or not the training has been completed.
- Previous training can transfer. Relevant training from a previous employer may be used if you obtain a current record of it.
Where the mode cycles differ (24 months for air, three years under the HMR), the practical choice for a mixed operation is the shortest one. Having one renewal date per person is easier to track than three.
Road: a brief note on ADR
For road carriage in Europe under ADR the training picture has two extra concepts that the air and sea rules do not use. Drivers of vehicles carrying dangerous goods need their own training and certificate, and undertakings involved in carrying or loading dangerous goods may need a dangerous goods safety adviser (DGSA) unless an exemption applies. Those are carrier and operator obligations more than booking-desk ones, but a forwarder that arranges ADR road legs should ask hauliers for the driver's certificate and the vehicle's approval as a matter of course. Check the current ADR text and your national competent authority for exemptions and thresholds.
What to put in a training record
The two published record lists are almost the same, so one record format can satisfy both. Built from 49 CFR 172.704(d) and IATA's training guidance, a good record has:
- The employee's name.
- The most recent training and assessment completion date (month and year is enough for IATA; the US rule wants the date).
- The function or functions the training covers, and any limit on classes or UN numbers.
- A description, copy or reference to the training materials used.
- The name and address of whoever delivered the training and the assessment.
- Evidence of the assessment result, meaning that the person was assessed as competent, and by whom.
- The next due date, with the 3-month early-renewal window noted for air training.
Keep records for the longer of the applicable rules, and be able to produce them quickly. 49 CFR 172.704(d) requires the record to be available on request to an authorised DOT official, and IATA's guidance says records must be available to the employee or the national authority on request. Customers and carriers increasingly ask for them too. TT Club's dangerous goods guidance for the supply chain makes the same point from the commercial side: obtain documentary evidence that the relevant staff of your customers, contractors and suppliers are trained, and if you have never asked or been asked for such records, the system is not yet working.
What goes wrong when untrained staff accept dangerous goods
The failures are repetitive, and each one starts with a person who did not know what they were looking at:
- Undeclared dangerous goods. Goods that are regulated but booked as general cargo: lithium battery products, aerosols, perfumes, paints, adhesives, and chemical samples are common examples. This is exactly the failure IATA's "general cargo" function exists to prevent. See our guides on lithium batteries by air and sea and limited and excepted quantities for the categories that most often arrive unlabelled.
- Wrong UN number or proper shipping name. A declaration that names the wrong entry leads to the wrong packing instruction, the wrong labels and, for sea freight, the wrong segregation. See segregation and stowage for what that does on a vessel.
- Mis-stated packing group. The packing group sets the packaging performance standard and, for air, the quantity limits. A lower-hazard packing group than the substance deserves means the package may not be strong enough for the journey.
- Marine pollutant omissions. A product that is environmentally hazardous but not otherwise regulated can still need a declaration by sea. See marine pollutants and UN numbers.
The consequences are practical before they are legal: the carrier refuses the cargo at acceptance, the shipment is delayed or offloaded, and the forwarder pays storage, re-handling and a late fee for a booking that earned them a margin of a few percent. On the enforcement side, US penalties are written into the regulations. 49 CFR 107.329, as updated in the Federal Register on 30 December 2024, sets a civil penalty of up to $102,348 per violation for a knowing violation (up to $238,809 where it results in death, serious illness, severe injury or substantial property destruction), a separate offence for each day of a continuing violation, and a minimum civil penalty of $617 for violations relating to training. These amounts are adjusted for inflation, so check the current figure. PHMSA publishes its enforcement outcomes in annual civil penalty reports, which regularly list training violations alongside undeclared shipment violations, so a missing training record is something an inspector looks for after any incident. Outside the US, penalties and carrier sanctions follow national law and each carrier's acceptance rules; check the authority in each country you ship from.
Also check your insurance. A policy may treat undeclared or mis-declared dangerous goods as an exclusion or a condition. Our guide to forwarder E&O, cargo and legal liability insurance explains what to ask the broker.
A dangerous goods acceptance checklist and a hard stop
Training only works if the booking process makes the trained person the one who decides. A simple internal control has four parts.
- Ask the question on every booking. A mandatory field in the booking form: dangerous goods, yes, no or unsure. "Unsure" is not allowed to proceed. It routes to a trained person who asks for the safety data sheet and the product details.
- Hard stop without a declaration. If the answer is yes, the booking cannot be confirmed to the customer or the carrier until a completed dangerous goods declaration is on file for the right mode, and a person trained for acceptance has initialled the checklist. For air, that is the Shipper's Declaration; see the declaration guide for fields and common errors.
- Use a short acceptance checklist. Before release, the trained person confirms: UN number, proper shipping name, class or division and any subsidiary risk match the safety data sheet; the packing group is stated; the quantity per package, number of packages and packing instruction or limited-quantity basis are stated; package marks and labels match the declaration; the packaging is in good condition with no leaks or damage; an emergency contact is provided; the declaration is signed and dated by the person responsible; and the carrier has accepted the DG booking in writing.
- Flag high-risk commodities for review. A keyword list in the quoting system (batteries, power banks, e-cigarettes, aerosols, perfume, paint, adhesives, cleaning products, chemical samples, dry ice, magnets, airbags) forces a second look even when the customer says no.
Also set a rule for who can override the stop. The answer should be nobody: if a customer is pressing, the decision goes to the named dangerous goods lead. Log refusals as well as acceptances; the log shows an auditor the system works, and it shows your own team where customers misunderstand the rules.
What to do next
- List every person who can accept, document or release a booking, and write down the functions each one performs, across all modes you use.
- Check each person's last training date, the function it covered and whether it included an assessment. Put the next due date, using the shortest applicable cycle, on a shared calendar.
- Build the training record format above and fill it in for current staff, including where the materials and the assessment evidence are stored.
- Add the dangerous goods question and the hard stop to your booking form, then test it with three real past shipments, including one that was not declared.
- Ask your key carriers, hauliers and co-loaders for their own dangerous goods acceptance requirements and for evidence of their staff training.
If you need a trained dangerous goods partner on a specific lane, more than 29,300 logistics companies are searchable by country and service in the CargoLinked directory, and the public requests board lists freight that shippers have posted for forwarders to quote on directly.
