Checked against the Marketing Discipline Guidelines 2024 (Ver. 1, effective 24.10.2024) on 15 October 2026. Published by MDG Services on 25 October 2026.
What it is for
It is your own copy of what was in the lorry. If an inspector's nozzle sample later fails, the lab tests it against this one MDG 2.5(G).
On every tank lorry, in order
Start after the density and water checks (see receiving a tanker), once density is within limits MDG 2.3.
- Rinse. Rinse the empty aluminium container with the lorry's own product MDG 2.3.
- Draw. From each compartment run off at least 20 litres, then draw a bottom composite in proportion to what each holds. Fill 2 x 1 litre for MS and/or 1 x 1 litre for HSD MDG 2.3.
- Seal and label. Seal the container and the wooden box, and fill in the Annexure 3 label MDG 2.3 MDG 2.7.
- Sign. You or your representative and the driver both sign the label MDG 2.3.
- Mark the tank number on the container if the product has more than one tank MDG 2.3 MDG 2.9.2.
- Then decant MDG 1.2(x).
The label ties the sample to one delivery, recording lorry, invoice, product, outlet, tank, both densities and the seal numbers MDG Annexure 3.
Which samples to keep
For each MS and HSD tank, keep the samples from its two latest loads:
| Product | Per load MDG 2.3 | For the last two loads of one tank MDG 2.9.2 |
|---|---|---|
| MS | 2 x 1 litre | 4 x 1 litre |
| HSD | 1 x 1 litre | 2 x 1 litre |
When not to decant yet
If the driver will not sign, do not decant. Contact the supply location or the sales officer MDG 2.3 Note (i).
If you notice an unusual time or route deviation by the lorry, tell the supply location or the sales officer and decant only after further instructions MDG 2.3 Note (ii). See vehicle tracking.
The transporter's set and the inspector
A transporter may ask for a second signed set against payment and holds it until testing and what follows are finished MDG 2.3 MDG 2.9.4.
An inspector takes your sealed box into custody without opening it: see inspector samples. If the inner container is later found leaking or tampered with, responsibility rests with the dealer or transporter whose sample it is, and the Note below applies MDG 2.5(C).
Note: if you cannot show your tank lorry samples at an inspection, a sample you produce later is not considered for testing. The nozzle sample is compared with the supply point sample, and any action is against the dealer only MDG 2.5(E). If your samples were already sent for testing, it is compared with that earlier result MDG 2024, chapter 2, General Notes (3).
Questions dealers ask
01Who supplies the sample containers, seals and labels?
The oil company, at no cost: containers, seals, wire, pliers and printed Annexure 3 labels. The dealer has to ask in good time MDG 2.6(B) MDG 2.7 MDG 2.8.
02Can the transporter keep a retention sample too, and what does it cost?
Yes, if he asks. He or the driver leaves a Rs 300 deposit for each container and arranges his own safe keeping. MDG does not say what the set costs; ask your oil company MDG 2.3.
03What do I do with the older sample when a newer load arrives?
MDG does not say what to do with it. Ask your oil company before you discard it MDG 2.9.2.
04Is there a penalty for not keeping the retention samples?
Chapter 5 has no separate line for a missing retention sample. A dealer found without them is told to follow the procedure MDG 5.1 Note (i). The one consequence MDG states: a sample produced later is not considered MDG 2.5(E).
