The Basis of measurement determines whether the quantity counts as mass (kg) or volume (litres) – it depends on the type of dangerous goods (ADR 1.1.3.6.2), not on free choice.
What is the 1000-point rule?
ADR 1.1.3.6 provides for a partial exemption if the quantity of dangerous goods carried per transport unit does not exceed a threshold. Each transport category has a Factor; the quantity is multiplied by the factor and summed across all items. If the total remains ≤ 1000, reduced requirements apply (e.g. no full transport document obligations, no vehicle marking required).
| Transport category | Factor | Maximum quantity per unit |
|---|---|---|
| Category 0 | – | 0 (no exempt quantity) |
| Category 1 | 50 | 20 |
| Category 2 | 3 | 333 |
| Category 3 | 1 | 1000 |
| Category 4 | 0 | unlimited |
The transport category for each UN number is given in ADR Table A, column 15.
Which quantity counts? Basis of measurement per 1.1.3.6.2
The “quantity” is not a freely selectable unit but is prescribed by the type of dangerous goods. That is why you choose the appropriate basis of measurement for each item in the calculator – mass (kg), volume (litres) or, for articles, the gross mass.
| Type of dangerous goods | Basis of measurement |
|---|---|
| Articles | Gross mass in kg |
| Solid substances, liquefied / refrigerated liquefied / dissolved gases | Net mass in kg |
| Liquid substances | quantity contained in litres |
| Compressed / adsorbed gases, aerosols | Capacity (water capacity) in litres |
| Class 1 (explosive substances / articles) | Net explosive mass in kg |
In the sum formula, mass and volume are added as dimensionless points after multiplication by the factor – what matters is the correct basis of measurement for each type of goods.
