Can I still modify or withdraw a submitted due diligence declaration?

Modification is not possible, withdrawal is

A due diligence statement that has been submitted once cannot be opened and amended afterwards. The EU information system for the deforestation regulation assigns a fixed reference number and a verification number to each submitted statement, and that registration is locked at the moment of submission. If someone discovers after submission that data is incorrect — a wrong plot, an incorrect supplier, an inaccurate risk assessment — they cannot quietly correct that error in the existing statement.

What is possible is to withdraw the statement via the information system, after which a new, corrected due diligence statement is submitted with a new reference number. For those working with a file per product stream, this means in practice that an error is first corrected in that underlying file — the plot, the supplier, the document — after which the statement built from that is resubmitted. Whether withdrawal and resubmission in a concrete case is the appropriate route, and what consequences this has if an inspection by a competent authority is already underway, is an assessment that lies with the market participant itself.

Where this is evident: design of the EU information system

This procedure follows from the design of the EU information system for the deforestation regulation, the register in which due diligence statements and simplified statements are submitted and in which each statement receives a unique reference number. The system is set up for registration of a statement at a specific moment, not for subsequent editing of an already submitted statement; corrections proceed via withdrawal of the existing registration and a new submission. For the precise operation, including the question of who on behalf of a market participant may withdraw and resubmit, the documentation of the information system itself is the designated source.
