Dangerous goods regulations catch SMBs off guard regularly — products you might not consider "dangerous" (lithium batteries, perfumes, paint) have specific shipping requirements. Non-compliance means fines up to £5,000, carrier account suspension, and potential liability for incidents. AskBiz flags dangerous goods at order level and generates compliant documentation.

The Products You're Shipping That Are Legally "Dangerous Goods"#
Most SMB owners who ship hazardous materials don't realise they're doing it. The regulatory definition of "dangerous goods" is much broader than the common understanding. Lithium batteries — including the batteries inside laptops, power tools, cameras, and e-cigarettes — are Class 9 dangerous goods under ADR (European Agreement on the Transport of Dangerous Goods) and IATA regulations. Perfumes, aftershaves, and hand sanitisers contain ethanol, which is a flammable liquid under Class 3. Aerosols — deodorants, spray paint, cleaning products — are Class 2. Paints and varnishes with flammable solvents are Class 3. Bleach and other strong oxidising cleaners fall under Class 5. If your SMB sells beauty products, consumer electronics, DIY supplies, cleaning products, or anything with a battery, there's a meaningful chance you're shipping dangerous goods — and there's a regulatory framework you need to follow.
What the Regulations Actually Require#
For road transport within the UK, the relevant framework is ADR (which the UK retained post-Brexit as UK ADR). For air transport, IATA Dangerous Goods Regulations (DGR) apply. The requirements vary by the type and quantity of dangerous goods, and there are important exemptions for small quantities ("Limited Quantities" or LQ provisions) that most SMB shipments can qualify for. Limited Quantities exemptions: if your product contains a relatively small quantity of the hazardous substance (limits vary by class — typically 1-5 litres or kg per inner packaging), it qualifies as LQ and has significantly reduced requirements. LQ shipments need: LQ mark on the outer packaging (a diamond-shaped label), proper inner packaging that prevents leakage, and a limited quantities declaration. For consumer electronics with lithium batteries (Section II batteries), the packaging must prevent short circuits, and the shipper must comply with IATA PI 966, 967, 968, or 969 depending on whether batteries are standalone or contained in equipment.
Carrier Rules vs Regulatory Requirements#
An important distinction: regulatory requirements set the minimum legal standard; carrier rules are often more restrictive. Royal Mail prohibits many dangerous goods entirely, including most flammable liquids. DPD accepts Limited Quantities shipments with proper documentation but requires a Dangerous Goods Acceptance Agreement to be in place. Evri has stricter restrictions and generally doesn't accept dangerous goods. DHL Express has a full dangerous goods acceptance framework but requires training certification. Before shipping any potentially dangerous goods, read your carrier's prohibited and restricted items policy carefully — it's usually longer than you expect and updated regularly. A carrier finding undeclared dangerous goods in a consignment results in: immediate seizure of the shipment, suspension or termination of your account, and potential referral to regulatory authorities. The reputational and operational consequences of a carrier suspension are significant for any business whose revenue depends on shipping.
Lithium Battery Shipping: The Most Common Compliance Gap#
Lithium batteries are the single most common dangerous goods compliance gap for UK SMBs. E-commerce businesses selling consumer electronics, power tools, mobility aids, garden equipment, or anything battery-powered are affected. The IATA regulations governing lithium batteries are detailed and updated annually. Key requirements for consumer electronics shipped by air: batteries must be at 30% state of charge or less (for standalone batteries). Outer packaging must be marked "LITHIUM BATTERIES — HANDLE WITH CARE — FLAMMABLE". Shipper's declaration (or exemption from declaration for qualifying items) must accompany the shipment. For lithium ion batteries in equipment (a laptop, for example), the device must be switched off and protected against accidental activation. For parcels containing lithium batteries going by road within the UK, ADR Section 1.1.3.10 provides an exemption for batteries contained in equipment for personal use — but commercial quantities require ADR compliance. AskBiz maintains a dangerous goods product flag database: when a product in your catalogue is identified as containing or being a dangerous good, it's flagged at order processing and the correct documentation is generated automatically.
Packaging Requirements for Dangerous Goods#
Packaging for dangerous goods is not discretionary. For Limited Quantities shipments, inner packaging must be leak-proof (for liquids) or sealed (for solids), and the outer packaging must be strong enough to withstand a 1.2-metre drop test. This is a standard corrugated cardboard box for most shipments — but it must be in good condition, not reused with existing markings that could cause confusion, and the correct LQ mark must be applied. For full dangerous goods shipments (above LQ limits), UN-certified packaging is required — this has a UN marking printed on the packaging that certifies it meets the specification for the goods inside. UN-certified packaging is available from specialist packaging suppliers and costs more than standard packaging. Don't try to use standard packaging for full DG shipments — the liability if something goes wrong is significant.
Training and Certification Requirements#
For businesses regularly shipping dangerous goods, training is a regulatory requirement. ADR requires that everyone involved in the transport of dangerous goods — including shippers and freight forwarders — receives appropriate training. For most SMBs shipping Limited Quantities goods, a basic online awareness course (several are available for £50-£150) is sufficient. For businesses shipping full dangerous goods consignments, more substantive training — typically the BTEC Level 3 or equivalent — is required. Annual refresher training is recommended as regulations change. If you're shipping dangerous goods by air, IATA DGR training is mandatory for anyone signing a shipper's declaration. The cost of training is trivial relative to the fine for non-compliance (up to £5,000 per breach) or the business impact of a carrier suspension. AskBiz's compliance module includes a training record function and reminds you when staff training renewals are due.
International Dangerous Goods: Additional Complexity#
Cross-border dangerous goods shipping adds layers of complexity beyond UK domestic requirements. Each country has its own implementation of the international dangerous goods framework, and restrictions on specific goods vary. Lithium batteries are particularly tightly controlled on passenger aircraft — many airlines now refuse pure battery consignments by air entirely, requiring surface transport for large battery shipments. Chemical products face import restrictions in many markets — what's freely sold in the UK may require an import licence in Singapore, Malaysia, or Gulf countries. For ASEAN cross-border dangerous goods, engaging a specialist dangerous goods freight forwarder is strongly recommended for any regular volume. The compliance overhead for self-managing cross-border DG shipments is substantial and the error risk is high.
Build Compliance Into Your Fulfilment Workflow#
The most effective approach to dangerous goods compliance isn't a periodic audit — it's embedding compliance into the daily fulfilment workflow so the right documentation, packaging, and carrier selection happen automatically at order level. AskBiz flags orders containing dangerous goods products at the pick-and-pack stage, generates the required documentation, and routes the order to a carrier that accepts the specific goods type. This means compliance happens without relying on team members to remember the requirements for every product — which, in a busy warehouse with staff turnover, is an unreliable approach.
