Who issues the DeCA at a quarry?

It depends on who hires the lorry. The Order defines the contracting shipper as whoever directly hires the transport from the party that performs it:

In every case, the obligation applies per consignment. If on the same day you load your own lorries and self-employed hauliers' lorries, only the self-employed hauliers' trips need a DeCA.

How it works at the weighbridge

  1. You weigh as alwaysWeight, material, customer and site come from the ticket or the delivery note in your software.
  2. The DeCA is generatedA PDF with its QR code and unique web address, created before the lorry leaves the quarry.
  3. The driver carries itVia WhatsApp or on the printed ticket with the QR code. At a check it's downloaded by scanning the code.

Unlimited trips at a fixed price

A quarry with 30 lorries a day sends around 650 consignments a month. Paying per document at €0.20–0.25 that would be €130–165; with DeCA, €25 a month per company.

FAQ

The customer collects with their own lorry. Who issues the DeCA?

The contracting shipper is whoever hires the transport. If your customer hires the lorry, the responsibility lies with them and the carrier. Even so, you can issue it yourself with your weighbridge data, since you're the one who knows the weight and the material.

Is the weighbridge ticket valid as a DeCA?

Only if it's a digitally generated PDF with all the data the Order requires (shipper, carrier, origin, destination, goods, weight, date and number plate) and a QR code leading to an address where the PDF downloads directly. A photo or scan of the ticket is not valid.

Do my own lorries need a DeCA?

No. With your own vehicles and your own goods it's private (own-account) transport. It's advisable to carry documents proving that the lorry and the aggregate belong to the company.

How much is the fine?

Not carrying the document or not completing it is a serious offence under article 141.17 of the LOTT, fined at 401 to 600 euros, and each trip counts as a separate offence.
