The annual negotiation between a supplier and a retailer in France is not a free negotiation. The French Commercial Code imposes formalities, makes the supplier’s general terms of sale the basis of the talks, requires a written agreement signed no later than 1 March, and prohibits subjecting a partner to obligations that create a significant imbalance (déséquilibre significatif, Article L. 442-1, I, 2°). For a mid-sized supplier facing a central purchasing body, these rules are not red tape: they are its only weapons. It still has to document the negotiation to use them.
A Breton fish cannery with 120 employees makes 40% of its turnover with two national retail chains. In December, it sends out its general terms of sale with a 7% price increase, justified by the cost of fish and energy. The purchasing body of one of the chains replies with a business plan demanding a 3% price cut, a contribution of 4% of turnover for “commercial cooperation” with no defined content, penalties of 2% for any service rate below 98.5%, and an automatic alignment on the lowest price granted to any other customer. On 20 February, nothing is signed. The sales director wants to know what he can refuse and what happens on 1 March.
1. The general terms of sale as the basis of the negotiation
A supplier that has general terms of sale (conditions générales de vente) must send them to any buyer who asks; they are the sole basis of the commercial negotiation (Article L. 441-1 of the French Commercial Code). The retailer cannot substitute its own general terms of purchase, and a negotiation that starts from a business plan drawn up in advance by the buyer, with no reference at all to the supplier’s terms, is a serious indication of coercion.
For fast-moving consumer goods, specific rules come on top (in particular Articles L. 441-1-1 and L. 443-8), including the requirement to take into account the cost of agricultural raw materials in the price, which cannot be negotiated for the share they represent.
2. The single agreement and the 1 March deadline
The negotiation ends in a written agreement (convention unique) that sets out the mutual obligations: the terms of the sale, the commercial cooperation services with their purpose, date and remuneration, and the other obligations intended to support the relationship (Article L. 441-3). It must be concluded before 1 March for annual relationships, or within two months of the start of the selling period for seasonal products. Breaches are punished by an administrative fine imposed by the DGCCRF, the French consumer and competition authority.
Law No. 2023-221 of 30 March 2023 dealt with a negotiation that has not concluded by 1 March: the supplier may end the entire commercial relationship with the retailer without the retailer being able to claim abrupt termination, or it may ask for a notice period in line with trade practice and for mediation. This mechanism is the subject of repeated parliamentary debate. Check the text that applies to the current round every autumn.
3. Significant imbalance: the concept
Article L. 442-1, I, 2° makes liable anyone who, in the course of commercial negotiation, the conclusion or the performance of a contract, subjects or attempts to subject the other party to obligations creating a significant imbalance in the parties’ rights and obligations. Two elements must be proved: the coercion or attempted coercion, which can be inferred in particular from the absence of real negotiation; and the imbalance, assessed in light of the contract’s overall economics.
The French Supreme Court (Cour de cassation) accepts that a significant imbalance can result from a mismatch between the price and the goods sold, so the price itself can be reviewed (Cass. com., 25 January 2017, No. 15-23.547). The Constitutional Council had upheld the concept against the principle that offences and penalties must be defined by law (Decision No. 2010-85 QPC of 13 January 2011).
The standard clauses that courts regularly sanction are well known: disproportionate flat-rate logistics penalties, with no link to actual loss and no way to escape them; automatic alignment on terms granted to a competitor; invoicing of commercial cooperation services that are fictitious or give nothing in return; one-sided termination or return-of-goods clauses. Article L. 442-1, I, 1° also sanctions obtaining an advantage that has no consideration or is manifestly disproportionate to the value of the consideration given.
4. Sanctions
The victim can obtain compensation for its loss and the nullity of the clauses. The Minister of the Economy and the public prosecutor can also ask the court to impose a civil fine of up to 5 million euros, or three times the sums unduly paid, or 5% of the turnover excluding tax made in France by the author of the practices, whichever is highest (Article L. 442-4). These actions go to specialised courts, including the Paris commercial court, now the economic activities court (tribunal des activités économiques), at first instance and the Paris Court of Appeal on appeal.
The major retail chains have been fined several million euros on several occasions in cases brought by the Minister. That public enforcement is real; private litigation, brought by the supplier itself, remains rarer, because few suppliers dare to sue the customer that accounts for a fifth of their turnover, and that is exactly why documenting the negotiation matters so much: it lets the supplier alert the DGCCRF, which can act without exposing the supplier, or sue on its own once the relationship is over, within the five-year limitation period, by producing dated documents rather than a recollection, whether these are the purchasing body’s emails, the successive versions of the business plan, the minutes of meetings or the invoices for commercial cooperation whose content nobody was ever able to describe.
5. What the cannery did
It answered the business plan in writing, point by point: its general terms kept as the basis, a costed justification for the increase, a request for a precise description of the commercial cooperation services, a reasoned refusal of the alignment clause and a proposed schedule of logistics penalties with a cap and grounds for exemption. Every exchange was kept. The agreement was signed on 28 February with a 4% increase, no alignment clause, and commercial cooperation reduced to 1.5% for identified operations.
The result is not spectacular, but it is defensible, and it is defensible because the negotiation left a paper trail.
6. Beyond food retail
Significant imbalance is not limited to food products. It applies to all relationships between commercial partners: industrial subcontracting, IT contracts, equipment distribution, financial leasing. Any non-negotiated clause that creates an imbalance to the detriment of the weaker party is exposed to Article L. 442-1 and, in standard-form contracts (contrats d’adhésion), to Article 1171 of the French Civil Code.

Frequently asked questions
Are the supplier’s general terms of sale binding on the retailer?
They are the sole basis of the commercial negotiation (Article L. 441-1 of the French Commercial Code). The retailer can negotiate them, but cannot set them aside in favour of its own purchasing terms.
What happens if the agreement is not signed by 1 March?
Under the mechanism introduced by the 2023 law, the supplier can end the relationship without the retailer being able to claim abrupt termination, or ask for notice and mediation, and the applicable text has to be checked every year.
What is a significant imbalance?
A disproportion in the parties’ rights and obligations, imposed by one party on the other without real negotiation. It is assessed against the contract’s overall economics and can concern the price.
Which clauses are often held to be unfair?
Flat-rate logistics penalties with no link to any loss, automatic alignment on a competitor’s terms, commercial cooperation with no real consideration, and one-sided termination or return clauses.
How large can the civil fine be?
Up to 5 million euros, or three times the sums unduly paid, or 5% of turnover excluding tax made in France, whichever is highest.
