DSA vs LoA

Data Sharing Agreement vs Letter of Access (biocides and PPP)

A Data Sharing Agreement (DSA) is the private contract that sets who may use which studies, for what purpose, and at what price. A Letter of Access (LoA) is the formal letter submitted to authorities so the beneficiary can cite those studies. You often need both. The DSA is usually not filed with ECHA; the LoA is.

In one sentence each: NDA: stop confidential information leaking during the first talks. DSA (short form): two parties, existing data, compensation, then an LoA. DSA (long form) / multi-party DSCA: task force or consortium: study list, cost shares, who may issue LoAs. LoA: the citation right the authority actually reads (BPR, PPPR or REACH).

Typical order: NDA, then optional Letter of Intent, then DSA or compensation agreement, then LoA, then submission in R4BP 3, to the Member State, or via REACH-IT. Mixing them in one Word file is how scope, payment and citation rights get confused, and how later versions diverge.
