The five-year floor Art. 13(8)
The core rule is short. During the support period, the manufacturer must handle vulnerabilities effectively, and the support period must be at least five years. The only way it is shorter is where the product itself is expected to be in use for less than five years, in which case the support period corresponds to that expected use time. So five years is a floor for ordinary products, not a fixed number for every product.
How you determine it Art. 13(8)
You do not pick the number arbitrarily. The support period must reflect the length of time the product is expected to be in use, taking into account in particular reasonable user expectations, the nature of the product including its intended purpose, and relevant Union law on product lifetimes. You may also weigh the support periods of similar products, the availability of the operating environment, the support periods of integrated third-party components providing core functions, and guidance from ADCO and the Commission, all considered proportionately.
For specific product categories where market surveillance data suggests support periods are inadequate, the Commission may adopt delegated acts specifying a minimum support period. So the five-year floor can be raised by category over time.
Where it must be documented and shown Art. 13(8), Art. 13(19), Annex II (7)
The support period is both an internal record and a customer-facing fact. The information taken into account to determine it must be included in the technical documentation. And the end date of the support period, including at least the month and the year, must be clearly and understandably specified at the time of purchase, in an easily accessible manner and, where applicable, on the product, its packaging, or by digital means. The user information also states the end date and the type of security support offered.
The separate ten-year update-availability rule Art. 13(9)
Do not confuse the support period with the ten-year figure that also appears in Article 13. They are different rules. The support period is how long you actively handle vulnerabilities and provide security updates. The ten-year rule is about keeping updates reachable afterwards: each security update made available to users during the support period must remain available, after it has been issued, for a minimum of 10 years or for the remainder of the support period, whichever is longer.
In practice that means a security update issued near the end of a five-year support period may still need to be downloadable for a decade after it went out, well past the end of the support period itself.
