How is Grant of Access (LoA) Pricing Determined?

17 August 2026 /KKDIK

Access Permit (Letter of Access / LoA) is the price of the right to access the common data set of a substance and directly affects the registration cost.

Pricing; The cost of creating the data is determined according to the required data coverage according to the tonnage band, the number of participants and the principles of fair sharing of the cost. A transparent and justified LoA is important for member registrars.

Main Items That Determine the Price

The access permit fee arises mainly from the production cost of the works in the file. Toxicological and ecotoxicological tests account for the majority of the total cost; In particular, long-term reproductive toxicity and environmental accumulation studies alone can determine the cost of the case. File preparation, forum management and administrative expenses are added to this. As the tonnage band increases, the cost gradually increases as the number of work required increases.

Grading According to Tonnage Band

In a fair model, the member logger pays only for work required by his tonnage band. Asking a company with a low annual amount to contribute to the cost of works produced for the upper bands is incompatible with the principle of transparency. For this reason, it is expected that the access permission offer will be presented on a band-by-band basis.

Retrospective Cost and Share Share

If the works were produced in previous years, the cost must be carried forward. In practice, updates are made based on inflation or a specific index. In addition, as the number of members joining the forum later increases, it should be determined from the beginning whether refunds or offsets will be made to members who have made payments before. When this rule is not written, permanent disagreements arise between those who joined first and those who joined later.

Transparency to be Required in the Offer

The access permit proposal should be itemized, showing which work is included and at what cost. The proportion of administrative expenses should also be stated. An undisclosed lump sum price does not meet the principle of transparency stipulated by the legislation and is open to objection. Requesting bids only for the work that the requesting party requires will reduce costs.

Pre-Negotiation Preparation

Before starting the meeting, it is necessary to clarify your own tonnage band, the data set you need and alternative routes. In some cases, producing your own data or closing the data gap with read-across may be more economical than the requested access permission fee. Bargaining power remains weak in negotiations without this comparison.
