What the table fields mean

Hazard identification number (Kemler): The first digit is the main hazard (2 gas, 3 flammable liquid, 4 flammable solid, 5 oxidising, 6 toxic, 8 corrosive, 9 miscellaneous), the next digits are additional hazards, a repeated digit (e.g. 33) means an intensified hazard, an X before the number means a dangerous reaction with water.
Transport category: The transport category (0 to 4) sets the multiplier: according to ADR Check, category 1: multiplier 50, category 2: multiplier 3, category 3: multiplier 1, category 4: multiplier 0 (no limit), and category 0 means the exemption does not apply. Points are the net quantity (kg or L) times the multiplier.
Multiplier for the 1000-point limit: Points are the net quantity (kg or L) times the multiplier; a load total not exceeding 1000 points falls within the ADR 1.1.3.6 exemption.
Limited quantity (LQ): The largest quantity per inner packaging for which carriage can use the limited-quantity rules.
Excepted quantity (EQ): A code indicating the limits for excepted quantities; its content is given in the text of ADR.
Packing instructions: Packing instruction codes (e.g. P, IBC, R) indicate which packagings are permitted.
Special packing provisions: Codes (e.g. PP, BB) add requirements to the packing instruction.
Mixed packing: Codes (MP) say how this substance may be packed together with others in one outer packaging.
Carriage, loading and unloading: The codes indicate provisions on carriage, loading and unloading.
Operation of the vehicle: Codes (e.g. S2, S20) indicate additional operating provisions for carriage.

The content of the packing codes and the carriage provisions is in ADR, chapters 4.1 and 7.
