1.2 Small Load Exemptions: ADR 1.1.3.6 and the 1,000-Point Rule
Key Takeaways
ADR 1.1.3.6 provides a practical exemption framework for transporting small quantities of packaged dangerous goods without triggering heavy-duty full ADR requirements.
Dangerous goods are categorized into Transport Categories 0 to 4, each carrying a dedicated calculation multiplier (50, 3, 1, 0, or zero-threshold).
Consignments qualify for regulatory relief only when the aggregate point score across all transport categories does not exceed 1,000 points.
When operating below the 1,000-point ceiling, vehicles do not require orange plates, ADR driver training certificates, Instructions in Writing, or full vehicle safety equipment.
Non-negotiable rules under 1.1.3.6 still include UN-approved packaging, hazard labelling, an ADR transport document with category point calculations, a 2 kg cab fire extinguisher, and driver general awareness training (Chapter 1.3).
Small Load Exemptions: ADR 1.1.3.6 and the 1,000-Point Rule
Operational Philosophy and Scope of ADR 1.1.3.6
Commercial freight frequently involves transporting small consignments of dangerous goods—such as maintenance solvents, laboratory chemicals, compressed gas cylinders, or paints—where deploying a fully equipped ADR vehicle and driver would be economically and operationally disproportionate. To address this, the UNECE framework provides ADR 1.1.3.6, universally known as the small load exemption or the 1,000-point rule.
The premise of ADR 1.1.3.6 is that the hazard presented by dangerous goods during transit depends on both substance severity and total volume. By limiting the quantity carried per transport unit, the potential consequences of an incident are kept within manageable limits.
Crucially, ADR 1.1.3.6 applies exclusively to dangerous goods carried in packages (such as drums, jerricans, boxes, gas cylinders, and IBCs). It never applies to:
- Dangerous goods carried in tanks (fixed tanks, demountable tanks, tank-containers, portable tanks, or battery-vehicles).
- Dangerous goods carried in bulk (loose solid goods carried directly in vehicle holds or bulk containers).
The limits apply to the transport unit as a whole (a motor vehicle with or without an attached trailer). Attaching a trailer does not increase the allowable point threshold; the entire combination shares the single 1,000-point limit.
Transport Categories and Multipliers (ADR Table 1.1.3.6.3)
Every dangerous substance in ADR Table A (Column 15) is assigned a Transport Category from 0 to 4, reflecting its hazard severity. This category determines the maximum quantity allowed under the exemption and the mathematical multiplier used for mixed loads:
| Transport Category | Maximum Quantity per Transport Unit | Multiplier | Representative Dangerous Goods |
|---|---|---|---|
| Category 0 | 0 | No mixed-load allowance | Use the exact entries in Table 1.1.3.6.3; any positive amount prevents this exemption |
| Category 1 | 20, with a 50-unit allowance for the goods specified in footnote (a) | 50, or 20 for footnote (a) goods | Class 3 PG I entries illustrate the ordinary category-1 case |
| Category 2 | 333 | 3 | Petrol UN 1203, Class 3 PG II |
| Category 3 | 1,000 | 1 | Diesel fuel UN 1202, Class 3 PG III |
| Category 4 | Unlimited | 0 | Division 1.4S and eligible empty uncleaned packagings; check the table’s exclusions |
The category in Table A column (15) governs. A hazard class, packing group or product nickname alone is not a safe substitute. Category 1 footnote (a) lists UN 0081, 0082, 0084, 0241, 0331, 0332, 0482, 1005 and 1017: the single-category limit is 50 kg and the mixed-load multiplier is 20. For example, excepted Class 7 packages have category-4 entries, so “all radioactive material is category 0” is incorrect.
Measurement Units for the Calculation
Under ADR 1.1.3.6.3, physical quantities are calculated using:
- Liquids: Total quantity actually contained, in litres; do not use the packaging’s nominal capacity.
- Solids: Net mass in kilograms. Articles: Total mass of the articles without their packagings, in kilograms; use net explosive mass for Class 1 and the total dangerous goods content for machinery/equipment where specified.
- Compressed gases: Water capacity of the receptacle in litres.
- Liquefied, refrigerated liquefied and dissolved gases: Net mass in kilograms.
The 1,000-Point Formula and Worked Manifest Examples
When transporting dangerous goods belonging to more than one Transport Category, the aggregate points must be calculated:
Total points = (ordinary Cat 1 quantity × 50) + (Cat 1 footnote (a) quantity × 20) + (Cat 2 quantity × 3) + (Cat 3 quantity × 1). Category 4 contributes zero. Respect the single-category table limits and all other applicable conditions.
Condition for Exemption: Total Points <= 1,000 and Quantity Cat 0 = 0.
If any substance of Transport Category 0 is present in any measurable amount, the exemption cannot be used. If the calculated score is 1,000 or fewer, the load qualifies for the exemption. If the score reaches 1,001 points, full ADR applies.
Worked Example 1: Compliant Mixed Consignment
A transport unit carries the following packaged items:
- 10 litres of a Class 3 PG I liquid confirmed by Table A as ordinary Cat 1: 10 x 50 = 500 points
- 80 litres of UN 1263 Paint, Class 3, PG II (Cat 2): 80 x 3 = 240 points
- 200 litres of UN 1202 Diesel Fuel, Class 3, PG III (Cat 3): 200 x 1 = 200 points
- 5 empty uncleaned drums previously containing paint (Cat 4): 5 x 0 = 0 points
Total Calculated Score: 500 + 240 + 200 + 0 = 940 points
Result: 940 <= 1,000 points. The consignment qualifies for the ADR 1.1.3.6 small load exemption.
Worked Example 2: Exceeded Mixed Consignment
A regional carrier loads:
- 150 litres of UN 1993 Flammable Liquid, N.O.S., Class 3, PG II (Cat 2): 150 x 3 = 450 points
- 600 kg of UN 2067 Ammonium Nitrate Fertilizer, Class 5.1, PG III (Cat 3): 600 x 1 = 600 points
Total Calculated Score: 450 + 600 = 1,050 points
Result: 1,050 exceeds 1,000 points. Full ADR applies immediately.
Regulatory Relief vs. Non-Negotiable Safety Mandates
Operating under ADR 1.1.3.6 provides substantial operational relief, but certain essential safety requirements remain strictly in force:
| Rule Category | Status Under 1.1.3.6 | Operational Details |
|---|---|---|
| ADR Driver Certificate | EXEMPT | Driver does not require an ADR vocational training card (Chapter 8.2). Standard licence suffices. |
| Orange-Coloured Plates | EXEMPT | Orange plates are not required when using this exemption. Do not confuse optional full compliance with an automatic offence; remove plates unrelated to the actual dangerous goods carriage. |
| Instructions in Writing | EXEMPT | Four-page emergency response document (ADR 5.4.3) is not legally required in the cab. |
| Vehicle Safety Kit | EXEMPT | Full equipment kit under ADR 8.1.5 (wheel chocks, warning signs, eye wash, drain seal, shovel) is not required. |
| Parking Supervision | CHECK RETAINED RULES | Check retained provisions: Chapter 8.4 and the retained special provisions, including S1(6), S14–S21 and S24, can still impose supervision requirements. 1.1.3.6 is not a blanket release from supervision. |
| Vehicle Approval (Part 9) | EXEMPT | Specialized vehicle certificates (EX/II, EX/III, FL, AT) are not required. |
| Packaging Standards | MANDATORY | Applicable packaging provisions in Parts 4 and 6 remain; UN design-type marks are needed where the relevant packing instruction requires them. |
| Package Labelling & Marking | MANDATORY | Applicable Chapter 5.2 marks and labels remain, including any specific exceptions or permitted size reductions. |
| Transport Document | MANDATORY | Must carry an ADR transport document (5.4.1) declaring total quantities and calculated points per category. |
| Fire Extinguisher | MANDATORY | Vehicle MUST carry at least one 2 kg dry powder extinguisher (ADR 8.1.4.2) for cab/engine fires, sealed and inspected. |
| Cargo Securing | MANDATORY | Cargo must be secured against shifting in compliance with ADR 7.5.7 and EN 12195-1 standards. |
| Smoking / Vaping Ban | MANDATORY | Total prohibition on smoking, vaping, and open flames during handling and near the vehicle (ADR 7.5.9 / 8.3.5). |
| Driver Awareness Training | MANDATORY | Driver and handling staff must complete verified Chapter 1.3 general awareness and safety training. |
| Mixed Loading Rules | MANDATORY | Segregation rules between incompatible hazard classes (ADR 7.5.2) and foodstuffs (ADR 7.5.4) still apply. |

A transport unit carries 10 litres of Class 3 PG I (Transport Category 1), 100 litres of Class 3 PG II (Transport Category 2), and 150 litres of Class 3 PG III (Transport Category 3). Does this load qualify for the ADR 1.1.3.6 exemption, and what is the total point score?
No, because any presence of Transport Category 1 automatically disqualifies a shipment from ADR 1.1.3.6
Yes, the total calculated score is 950 points, which does not exceed the 1,000-point limit
Yes, because the total liquid volume of 260 litres is below the 1,000-litre single-substance maximum
No, because Transport Category 2 and Category 3 liquids cannot be combined on the same transport unit
When a consignment of packaged dangerous goods is carried under the small load exemption of ADR 1.1.3.6, which safety item must STILL be carried on the transport unit?
Two self-standing reflective orange warning triangles and an emergency eye wash bottle
A four-page UNECE standard Instructions in Writing emergency document in the driver cab
At least one portable 2 kg dry powder fire extinguisher suitable for engine and cab fires
A drain seal cover and an anti-static collection container for spillage containment
Which of the following requirements remains strictly MANDATORY for the driver and carrier when transporting dangerous goods within the ADR 1.1.3.6 threshold?
Displaying plain orange-coloured plates on the front and rear of the vehicle
Holding a valid ADR Driver Training Certificate issued under Chapter 8.2
Displaying hazard placards and orange plates under Chapter 5.3
Carrying an ADR transport document specifying the quantities and calculated point values for each transport category
What is the maximum permissible total quantity of a substance assigned to Transport Category 0 that can be transported under the ADR 1.1.3.6 small load exemption?
0 units (any quantity of Transport Category 0 immediately triggers full ADR requirements)
20 kilograms or litres
50 kilograms gross mass
333 kilograms or litres
