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.
