This indemnity will be due as of right from the first day of delay of payment for each unpaid invoice. This compensation is not subject to VAT and will not be taken into account in the basis for calculating late payment penalties.

This lump-sum compensation is not limited to the amount of other expenses that may be incurred by CLESTRA for the purpose of collecting its invoices. The costs and fees incurred by the contentious recovery of the sums due will always be charged to the CLIENT.

The payment of the above-mentioned late payment penalties is not a discharge.

Without prejudice to the provisions of Article 4 and Article 9, the CONTRACT shall be terminated or rescinded by operation of law, at CLESTRA’s discretion, in the event of the CLIENT’s failure to perform any of its material obligations, fifteen days after notice of default has been served without result. As regards damages, it is hereby agreed that CLESTRA will retain all sums already paid by the CLIENT, which constitute only a conventional minimum compensation. The CUSTOMER undertakes to compensate CLESTRA in full for all direct and indirect loss suffered by CLESTRA as a result of such termination or cancellation.

In the event of the occurrence of one of the events contractually assimilated to a case of force majeure in Article 13 that is likely to delay, prevent or render economically exorbitant the execution of the CONTRACT, the latter will be suspended or terminated, without compensation, at CLESTRA’s initiative by registered letter with acknowledgement of receipt to the CLIENT.

The CUSTOMER may request the termination of the CONTRACT if he/she can prove a legitimate interest. Such termination shall only occur, at CLESTRA’s discretion, if the products have not been ordered or their production started. In any event, such termination shall result in the payment by the CUSTOMER of a minimum indemnity of 20% of the amount of the CONTRACT. The payment of the indemnity does not release CLESTRA from any claim for damages.


The agreed delivery dates are subject to the signature of the CONTRACT and, if agreed, to the payment of the deposit by the CUSTOMER. Unless otherwise specified in the PC, the delivery time is given as an indication only.

If the PCs expressly provide for a firm delivery date, CLESTRA is obliged to meet this date subject to:

  • the non-occurrence of a case of force majeure such as: epidemic, state of war, requisition, fire, flood, tooling accident, strike, disruptions in transport or information networks, disruption in the supply of raw materials or energy sources and, more generally, any cause leading to a total or partial stoppage of CLESTRA’s activity or that of one of its suppliers, subcontractors or transporters

  • the non-survival of unforeseen benefits,
  • the non occurrence of additional work,

Any delay in the delivery or performance of the CONTRACT for reasons wholly or partly attributable to the CUSTOMER or to a third party shall automatically result in the postponement of the delivery or acceptance date of the work for at least the same period of time.

Any delay that is not attributable to CLESTRA and that causes additional difficulty in carrying out the work will be subject to additional invoicing.

A delay in delivery or performance may only give rise to a penalty or damages if it is directly and exclusively attributable to CLESTRA and has constituted a real loss that has been established by mutual agreement, and if the PC has expressly provided for the possibility of such a delay with the reciprocity of a premium in the event of an advance payment. In addition, the CUSTOMER shall be liable to pay late payment penalties to his own customer.

If such a penalty has been expressly stipulated, it shall in no event exceed 5% of the pre-tax price of the PRODUCTS whose delivery is delayed or, in the case of services, of the pre-tax price of the services alone.


If not specified in the CP, the price of the products is exclusive of transport, customs, labour, installation and supervision costs.

In the absence of a provision in the PCs, the products travel at the risk of the CLIENT who, in the event of delay, damage or shortage, must exercise its recourse against the carriers in the forms and timeframes necessary for the investigation of the claim and make the necessary reservations with the latter to allow the exercise of its recourse.

In order to be able to invoke the benefit of this clause, the CLIENT must have complied with the terms of payment provided for in the CONTRACT, notified CLESTRA without delay and in writing of the defects it claims to have in the Products and provided all evidence as to the reality of the defects. It must also provide all facilities for CLESTRA to ascertain such defects and to remedy them.

The CUSTOMER shall only benefit from specific guarantees regarding the technical and industrial performance of the products (acoustic performance, fire resistance, etc.) if these are specifically accepted by CLESTRA in the PCs in terms of an obligation of result.

CLESTRA’s liability is strictly limited to the obligations stipulated in the CONTRACT and, in any event, to direct and foreseeable material damage, which is capped at the price excluding tax of the products or services in question. With the exception of gross negligence on the part of CLESTRA and compensation for personal injury, CLESTRA shall not be liable for any other compensation. CLESTRA shall in no event be liable to the CLIENT for any indirect and/or consequential damages, such as loss of profit, operating loss or commercial loss.


It is expressly stipulated, as an essential condition, that the PRODUCTS remain the property of CLESTRA until full payment of the price, costs and accessories.

CLESTRA shall be entitled to enforce its rights under this clause on all products sold to the CLIENT, the latter being, by express agreement, deemed to be the unpaid products.

In the event that CLESTRA claims the delivered products in accordance with this clause, the resulting costs, in particular the cost of returning the products, shall be borne by the CLIENT.

In the event of multiple claims, the reserved property shall secure all current or future claims against the CUSTOMER.

In the event of a claim, the insurance indemnity shall be automatically subrogated to the products of which CLESTRA has remained the owner.

The CLIENT undertakes to keep the products in good condition and to insure them on behalf of CLESTRA until they are paid for in full. Likewise, any modification or alteration of the products is prohibited. In the event that the CLIENT violates this prohibition, the CLIENT hereby assigns to CLESTRA the ownership of the products resulting from the processing in order to secure CLESTRA’s rights.

The CLIENT undertakes to inform CLESTRA immediately in the event of receivership or liquidation, as well as in the event of seizure or other measures affecting the goods. He/she shall not create any security interest in the property and shall not carry out any transaction that may prejudice CLESTRA’s right of ownership.

The CLIENT shall not sell the goods before full payment has been made without the prior consent of CLESTRA. In the event that the CUSTOMER contravenes this prohibition, the CUSTOMER hereby declares that he/she will assign the claim arising from the resale to a sub-purchaser. He shall not be entitled to collect the price owed by the sub-purchaser to the extent of the sums still owed to CLESTRA and he shall be obliged to inform the sub-purchasers of the assignment of the claims of which CLESTRA is the beneficiary.
