What is a Transfer Impact Assessment (TIA)?
A Transfer Impact Assessment (TIA) is the documented analysis a data exporter performs before transferring personal data to a third country on the basis of appropriate safeguards such as standard contractual clauses: do the laws and practices of the destination country prevent the data importer from honouring those safeguards — in particular through government access to data?
Where it comes from, and when you need one
The requirement crystallised in the CJEU’s Schrems II judgment: SCCs remain valid, but only if the parties verify they can be complied with in practice. A TIA is expected for every SCC-based transfer under GDPR, and the same logic increasingly informs Turkish practice under KVKK’s 2024 standard-contract regime — the Board’s safeguards presuppose that the importer can actually deliver them. The everyday triggers for a startup: routing customer data through a US-hosted model API, using a foreign cloud or analytics stack, or granting a foreign parent’s support team access to production.
What a defensible TIA contains
Five sections, kept short and honest. The transfer map: categories of data, purposes, recipients, onward transfers. The safeguard relied on (SCC module, BCR). The destination-law assessment: surveillance and government-access regimes applicable to the importer’s sector, with sources. The importer’s practical experience: history of access requests, ability to challenge them, transparency reporting. And supplementary measures where risk remains — encryption with exporter-held keys, pseudonymization before export, split processing. The conclusion is a judgment call, but a documented one — which is precisely what regulators and enterprise customers ask to see.
Is a TIA legally mandatory under KVKK?
KVKK does not name the instrument, but the 2024 standard contracts commit the parties to safeguards that only make sense after such an analysis; treating the TIA as part of the SCC file is the defensible reading and matches emerging practice.
How often should it be refreshed?
On material change — new subprocessor, new destination, new surveillance law — and otherwise on an annual cycle alongside your records of processing.
