Use this rule set:
- For physical products, including hardware plus software that is part of that product, determine the support period at the level of each individual unit when that unit is first placed on the EU market.
- Do not use manufacturing date as the support-period start date.
- Do not use later distributor sale, activation, installation, or first use as the support-period start date.
- Treat stock already in the distribution chain as already placed if the first EU supply event has already occurred.
- For direct online sales, determine the placement date from the actual distribution model, not from marketing language alone.
- For standalone software delivered digitally, the current Commission draft guidance points to the first EU offering of the unchanged version as the placement date.
- If a software or product change is a substantial modification, treat the modified product as a new product with a new placement event and a new support-period determination.
- Track component support periods, but do not treat them as automatic caps on the finished product's support period.
- Track Article 13(9) separately: each security update issued during the support period must remain available for at least 10 years after issuance or for the remainder of the support period, whichever is longer.
- Record in the technical documentation exactly what factors were used to justify the support period.
