What is DGR (Dangerous Goods Regulations)?
DGR (Dangerous Goods Regulations) is the International Air Transport Association's comprehensive framework defining how hazardous materials must be classified, packaged, labelled, and transported via commercial aircraft. For UK courier and air freight operators, DGR compliance is non-negotiable and covers everything from flammable liquids to radioactive materials and biological substances.
Definition and Core Purpose
DGR (Dangerous Goods Regulations) establishes global safety standards for air transport of hazardous materials. Published and maintained by IATA, DGR is updated annually and binding on all airlines, ground handlers, and freight forwarders across the globe. The regulations exist to protect crew members, passengers, ground staff, and the general public from the risks posed by hazardous cargo. In the UK, all air freight operations at Heathrow, Gatwick, Stansted, Luton, Manchester, and other major airports must comply strictly with DGR requirements.
"DGR compliance isn't just regulatory paperwork — it's about protecting lives. Every hazardous shipment we handle at T&C Logistics undergoes rigorous classification and documentation checks. We've processed over 2,000 dangerous goods shipments annually without a single incident, and that's because we treat DGR not as a box to tick, but as a core safety protocol." — Taras, Founder, T&C Logistics
How DGR Works in Practice
DGR operates through a classification system that assigns hazardous materials to nine classes, ranging from explosives (Class 1) to miscellaneous hazards (Class 9). Each class has specific packaging requirements, labelling standards, and transport restrictions. For example, lithium batteries (Class 9) require special packaging and documentation before air transport; flammable liquids (Class 3) must be packed in approved containers with distance limitations in cargo holds. In the UK, T&C Logistics maintains a dedicated team trained to classify, document, and safely handle all DGR-regulated shipments across our specialised air freight collection network covering 14 major airports.
Every DGR shipment requires a Shipper's Declaration for Dangerous Goods (SDDG) — a crucial document that certifies the contents, hazard class, proper shipping name, and emergency contact information. This document must be completed accurately and signed by an authorised shipper; errors or omissions can result in flight delays, shipment rejection, or regulatory penalties up to competitive rates for operators. Our team reviews 100% of SDDG documentation before any collection to ensure compliance.
Why DGR Matters for Your Delivery
If you ship pharmaceuticals, chemicals, lithium batteries, temperature-controlled medical materials, or any hazardous substance by air, DGR compliance directly affects your delivery timeline, cost, and legal liability. Non-compliant shipments are rejected at airport security, causing 2–5 day delays. Our same-day courier service includes DGR-compliant air freight collections from all UK airports with 30–60 minute response times, ensuring your hazardous materials leave the ground fast and safely. We handle pharmaceutical air freight, aviation AOG (Aircraft on Ground) urgent parts shipments, and industrial chemical transport with full DGR certification.
Examples of DGR-Regulated Materials
Common items subject to DGR include: lithium-ion batteries (mobile phones, laptops, power tools), flammable liquids (solvents, perfumes, paints), compressed gases (oxygen, nitrogen cylinders), corrosive substances (acids, alkalis), infectious substances (blood samples, diagnostic kits), and magnetic materials. Even household items like spray cans, lighters, or alcoholic beverages exceed DGR thresholds in certain quantities. Many UK shippers are surprised to learn that their products require DGR classification — our transport specialists identify this during the quotation process to prevent last-minute surprises.
DGR Documentation and Training
All T&C Logistics staff handling dangerous goods complete annual IATA DGR training and hold valid certification. This training covers hazard identification, proper packing, labelling, documentation, and emergency response. We maintain up-to-date knowledge of the latest DGR amendments (the 2024–2025 edition includes new lithium battery restrictions and revised biological substance categories). Your shipment benefits from this expertise: we identify packaging gaps, ensure correct labelling, and submit complete documentation to airlines on your behalf, reducing rejection risk to near-zero.

Related Questions
- What does DGR stand for, and who created it?
- DGR stands for Dangerous Goods Regulations and is published by IATA (International Air Transport Association), the trade organisation representing airlines worldwide. IATA updates DGR annually to reflect new hazard classes, packaging innovations, and safety research. The UK Civil Aviation Authority (CAA) enforces DGR compliance for all aviation operations in British airspace.
- Which materials require DGR compliance for air transport?
- Nine classes of materials require DGR compliance: explosives, gases, flammable liquids, flammable solids, oxidisers, toxic substances, radioactive materials, corrosive substances, and miscellaneous hazards. Common examples include lithium batteries, pharmaceuticals, laboratory samples, industrial chemicals, paint, perfume, and oxygen cylinders. If you're unsure whether your cargo is regulated, call T&C Logistics and our team will classify it free of charge.
- What is a Shipper's Declaration for Dangerous Goods (SDDG)?
- An SDDG is a legally binding document signed by the shipper certifying that dangerous goods are correctly classified, packaged, labelled, and documented for air transport. It includes the hazard class, proper shipping name, quantity, packing group, and emergency contact information. Falsifying or omitting information on an SDDG is a criminal offence in the UK, with penalties up to £20,000.
- Can T&C Logistics handle my DGR-regulated shipment?
- Yes — T&C Logistics specialises in DGR-compliant air freight collections from all 14 major UK airports (Heathrow, Gatwick, Stansted, Luton, Manchester, Birmingham, and others) with same-day collection available 24/7. Our team is IATA-trained and certified, and we maintain 100% compliance across pharmaceutical, chemical, and industrial hazardous shipments. Contact us on +44 7963 400173 or request a quote to confirm your specific requirements.
- What happens if my shipment is non-compliant with DGR?
- Non-compliant shipments are rejected at airport security, causing 2–5 day delays while you repackage and redocument. Airlines may refuse to carry the cargo entirely, forcing you to rebook via ground transport or international couriers. Shippers face regulatory fines up to £20,000 for violations. Our review process catches compliance issues before collection, ensuring your shipment clears airport security on the first attempt.
