Quick answer
The CERN principle that ties contract volumes awarded to a member state roughly to its share of the organisation's annual budget contribution, creating a quasi-guaranteed allocation across 24 member states.
Juste retour, French for "fair return," is the industrial return policy applied by CERN and several space agencies that links the volume of contracts awarded to companies from a member state to that state's proportional contribution to the organisation's annual budget. The policy creates a form of quasi-guaranteed allocation across the membership rather than awarding all contracts purely on price and quality alone.
What is Juste Retour (Industrial Return Policy)?
At CERN, with 24 member states and an annual procurement budget of CHF 1.3 to 1.5 billion, juste retour means that each member state aims to receive contracts roughly proportional to its budget share. The host states, France at 31 percent and Switzerland at 27 percent, receive the largest allocation. Across the membership, direct contracts flow approximately as follows: member states receive 92 percent, associated members 5 percent, and non-members 3 percent of direct contract value. CERN tracks industrial return ratios (the ratio of contract value received to budget contribution paid) for each country and publishes them, allowing both the organisation and national industry representatives to identify imbalances.
In practice juste retour creates opportunity signals for suppliers. A country whose return ratio is below its expected share has an underallocation that CERN and the member state will seek to correct in future procurements. Suppliers from underallocated member states are in a structurally favoured position for upcoming contracts, provided they are competitive on technical and commercial terms. This does not override competition, but it gives a country's companies a visibility advantage in how CERN manages its pipeline toward balance.
Why Juste Retour (Industrial Return Policy) matters for bidders
For suppliers from CERN member states, tracking the published industrial return ratios is a practical business intelligence tool. A supplier from a country that is running below its expected return can approach CERN procurement in the knowledge that correcting the imbalance is a policy objective, which increases the likelihood of that country's companies receiving serious consideration when they are competitive. For suppliers from non-member or low-contribution states, juste retour signals that direct CERN contracts are structurally harder to win, and that subcontracting to a prime contractor from a member state is often a more practical route into the supply chain.
FAQ
Does juste retour mean contracts are simply allocated to companies without competition?
No. Juste retour guides portfolio management across the membership over time, but individual contracts are still awarded through competitive procurement. A supplier from an underallocated country still needs to submit a technically and commercially competitive bid.
Is juste retour used outside CERN?
Yes. Space agencies including ESA apply a similar industrial return principle for their member state contributions, linking contract volumes to national budget shares in the same way CERN does.
How can a supplier find out if its country is underallocated at CERN?
CERN publishes industrial return statistics on its procurement portal, showing each member state's return ratio relative to its contribution. National industrial liaison offices and industry associations often monitor and communicate these ratios to domestic suppliers.
