1. Application – exclusivity
These general terms and conditions of sale apply to every order placed by the Customer. The Customer
confirms having read the terms and conditions, accepts them in full, without any reservations and waives
its own terms and conditions. The general terms and conditions exclude the Customer’s terms and
conditions, even if these are specified in a commercial document of the Customer, for instance in a
purchase order, and regardless of when the Customer presents its terms and conditions or wishes to
impose them, and even if the Customer’s terms and conditions state that Keller’s do not apply. A
reference by Keller to a commercial document of a Customer shall never be interpreted as an acceptance
by Keller of the Customer’s terms and conditions. Keller may only be considered to have waived its
general terms and conditions by way of a document specifically and exclusively drafted for this purpose
and signed by a person authorised in accordance with the articles of association to bind Keller.
If and to the extent that the special contractual conditions deviate from these general terms and
conditions of sale, the special contractual conditions shall take precedence.
2. Quotation – order confirmation
All quotations, price estimates and price lists shall be non-binding for Keller and shall be handed over to
the Customer without any obligation or liability. It is the Customer’s responsibility to provide Keller with
complete and correct information for a proper consideration of the order and to always carefully examine
all details contained in the quotations and to immediately inform Keller of any erroneous underlying data
or potential difficulties in fulfilling the order. Any order or contract placed by the Customer shall be
binding on the Customer. On the other hand, Keller shall only be bound after sending a written order
In the event that Keller fulfills an order as a subcontractor, the provisions of the contract with the
principal shall have no effect on the contract between the Customer and Keller, unless Keller accedes to
these provisions by means of a document drawn up specifically and exclusively for this purpose, which is
signed by a person authorised in accordance with the articles of association to bind Keller. Unless
otherwise expressly agreed, Keller shall at all times be entitled to outsource all or part of the order to
All prices stated in the quotation are always exclusive of VAT and exclusive of additional costs such as
costs of packaging, customs duties, transport, insurance, security, etc, unless expressly agreed
otherwise. The price estimate applies to delivery of goods and execution of works under normal
conditions. Additionally, the prices are based on work performed during Keller’s normal working hours.
Any additional costs resulting from overtime requested by the Customer, work on Saturdays or Sundays,
night work or work on public holidays shall be charged in accordance with the applicable scales.
Delivery periods are always based on an estimate and are indicative. If the execution of a delivery or
work depends on documentation or information provided by the Customer and this documentation or
information is not provided at the agreed times, the delivery deadlines shall not be extended
proportionally, but must be renegotiated. Any penalty clauses shall lapse in this case.
The risk of loss or damage to the goods shall be transferred from Keller to the Customer at the time of
delivery. If the Customer fails to collect the goods or postpones collection, the goods shall be stored at
the Customer’s expense and risk, without this affecting the terms of payment.
6. Duty to examine and complaints
It is the Customer’s duty to thoroughly examine and test the delivered goods and executed works within
a period of eight calendar days after delivery. The costs of inspection and other checks not provided for
in the contract shall be borne by the Customer. Any complaint regarding non-conformity or defects in
the goods or work performed must be notified to Keller by registered letter within eight calendar days of
discovery of the non-conformity or defect, or of the date on which the non-conformity or defect should
have been discovered. The notification shall contain a precise description of the non-conformity or
defect. If the non-conformity or defect is hidden, in the sense that it is not visible after thorough
examination, it must be notified in the same way within a period of eight calendar days after its
The Customer may not refuse delivery and acceptance of the goods and works performed and may not
postpone payment if there are minor imperfections which can be repaired during the guarantee period
and which do not prevent the use of the goods or the executed works. If the Customer uses or
processes the goods or executed works, the use or processing shall be deemed to constitute acceptance
of the visible condition of the goods. These conditions shall apply strictly and failure to observe them
shall result in the inadmissibility of the complaint.
The period for bringing an action on the grounds of defects rendering the sale void or on the grounds of
defective execution of the work shall be set at one month from the discovery of the defect.
If Keller’s order includes an engineering assignment, whether or not for a separate fee, it shall be the
Customer’s responsibility to provide Keller with all data and documents reasonably required for the
proper execution of the engineering work. These data and documents must be complete and correct.
Keller is absolved of the obligation to check the data and documents for accuracy. If the Customer
provides deviating, incorrect or incomplete data or documents, Keller shall not be liable for any related
conceptual errors or for non-fulfilment of the contractually agreed specifications and performances.
Necessary corrections will give rise to an additional charge. If no agreement can be reached on the
additional charge, Keller shall be entitled to unilaterally terminate the entire order, without prejudice to
Keller’s right to be compensated for all damages.
8. Safety and wellbeing
Prior to the conclusion of the contract, the Customer shall provide all necessary information regarding
risks and measures concerning the safety and wellbeing of Keller personnel at the worksite, which apply
at its location. If Keller is not informed or is inadequately informed, Customer shall bear all responsibility.
Any additional costs in this case shall be borne by the Customer. The Customer shall arrange for the
coordination of the work of external companies and the necessary cooperation with such companies in
the application of measures relating to the safety and welfare of employees at work, in accordance with
the provisions of the Welfare Act, the Codex on Welfare at Work and other applicable legislation.
shall never be obliged to perform work in hazardous conditions. The works must always be performed in
an asbestos-free environment and without involving any materials containing asbestos. The Customer
shall allow Keller’s personnel to use its sanitary and other facilities as prescribed by the A.R.A.B. and the
Codex on Welfare at Work.
Keller pledges that all goods and works shall comply with the contractual requirements. Subject to the
stipulations above regarding ‘Duty to examine and complaints’, this guarantee is valid for a period of one
year from the date of delivery. The guarantee shall only oblige Keller to replace or repair the delivered
goods or to redo or correct the work performed, this at Keller’s discretion. The guarantee cannot be
invoked in the event of normal wear and tear of the goods or works, improper use of the goods or
facilities, chemical influences, modifications made by the Customer and, in general, in the event that
Keller is not responsible for the non-compliance with the contractual requirements. Under no
circumstances can the guarantee be invoked by the Customer if the Customer is in breach of its payment
obligation. The costs arising from an inadmissible claim under the guarantee shall be invoiced to the
10 Additional work – downtime
Keller shall always be entitled to compensation if additional work is required due to the actions of the
Customer or a third party. Additional work shall be paid according to prices agreed upon between Keller
and the Customer or according to market prices. Keller reserves the right to suspend delivery until there
is written agreement with the Customer on the nature, execution and price of the additional work. If the
work cannot be performed as planned due to the actions of the Customer or a third party, Keller shall be
entitled to compensation for the downtime. This compensation shall cover the cost price of the material
and personnel made available for the works, the fixed costs and the reasonably expected profit. Keller
reserves the right to leave the worksite and continue working at a later date in line with internal
If the Customer cancels an order or if Keller is entitled to discontinue the order under the contractual
agreements, including these general terms and conditions of sale, Keller shall be entitled to full
compensation, consisting of compensation for all costs incurred (all expenses and all labour) and for
everything Keller was entitled to gain from the contract, including the margin. The compensation shall
never be lower than 35% of the contract price. The Customer agrees that compensation of 35% of the
price is a reasonable estimate of the damage Keller may suffer as a result of the cancellation.
All invoices are payable to Keller’s registered office.
If Keller’s invoices are not disputed by the Customer within a period of fourteen calendar days, these
invoices shall be regarded as accepted.
The payment deadlines are strictly applicable. A breach of these deadlines constitutes a serious breach
of contract on the part of the Customer which entitles Keller to suspend performance of the contract or
to terminate the contract immediately.
In the event of non-payment on the due date, the Customer shall automatically owe default interest of
12% per annum on the unpaid amount, without notice of default being required. Moreover, in the event
of non-payment on the due date, the Customer shall be liable, by operation of law and without any
notice of default being required, to pay a fixed compensation of 15% of the amount of the invoice, with
a minimum of €250.00, to cover extrajudicial collection costs.
The non-payment on the due date of one invoice automatically makes all other outstanding invoices,
even those not yet due, immediately due and payable in full.
13. Change of order and additional work
Keller shall only be bound by a changed agreement or by the performance of additional work if this
change or the additional work is approved in writing.
14. Retention of title
As security for the payment of all goods delivered, works performed and services provided by Keller, the
delivered goods shall remain Keller’s property until full payment for all such goods, works and services
has been made. The retention of title shall also apply as security for the payment of interest, damages
and any costs arising from a possible default of payment.
Until such time as the title to the goods is transferred to the Customer, the Customer shall store the
delivered goods with due care. Among other things, the Customer undertakes to secure the goods, to
take the necessary measures to avoid damage and to insure these goods.
The delivered goods shall be clearly marked by the Customer as being the property of Keller until such
time as the transfer of title has taken place.
The Customer undertakes not to resell the goods to third parties or to encumber them with a
preferential right or otherwise.
Keller shall be immediately notified in writing of any fact which is of such a nature as to affect Keller’s
property rights (damage, seizure, etc).
Keller shall be entitled, subject to prior notice, to inspect the goods in order to verify the Customer’s
compliance with the above provisions and the condition of the goods.
If the goods are taken back, this shall be done at the expense and risk of the Customer.
Any advance payment shall be retained by Keller as compensation for damages, without prejudice to
Keller’s right to demand higher compensation if there is reason to do so.
15. No compensation or exception
The Customer waives the right to offset any compensations owed to it by Keller with the amount of
outstanding invoices of Keller. Nor may the Customer suspend its own obligations should Keller default
on its obligations.
16. Force majeure and hardship
Keller is the only party who can invoke force majeure. The Customer’s option to be relieved of its
obligations or to have them suspended due to force majeure is expressly excluded here. Force majeure
means any unforeseeable event beyond the reasonable control of Keller or any foreseeable event, the
consequences of which cannot be reasonably avoided by Keller (including, without limitation, epidemics
and pandemics, government decisions, strike, lockout, transport interruption, fire, flood, riot, machinery
breakdown, total unavailability of materials, raw materials or parts, war and embargo), which occurs
after the conclusion of the agreement and which makes the performance of the agreement by Keller
completely or partially impossible. In the event of force majeure, Keller’s obligations shall be suspended
for the duration of the force majeure. Keller undertakes to notify the Customer without delay if an event
of force majeure occurs. The Customer and Keller shall immediately enter into discussions with a view to
finding a solution and shall take all reasonable measures to limit the consequences of the force majeure.
If the force majeure situation persists for more than three months and Keller and the Customer have not
agreed on a solution, the Customer or Keller may terminate the contract without being entitled to claim
any compensation. The Customer shall in any case be obliged to reimburse all deliveries and all work
carried out up to the time of the occurrence of force majeure.
Should circumstances arise that were unforeseeable at the time the contract was concluded, or that
were foreseeable but unavoidable, and these circumstances make it unreasonably difficult for Keller to
perform its obligations (this without prejudice to the application of any price review formulas), either
because they affect the scope, or the timing, or the cost of performance, the Customer and Keller shall
renegotiate the contract with a view to granting Keller reasonable compensation. The Customer and
Keller shall conduct these negotiations in good faith. Keller is entitled to suspend its obligations during
the negotiations. If the renegotiations are dismissed or fail within a period of one month, Keller may
apply to the court to amend the contract to bring it into line with what the parties would reasonably
have agreed upon at the time of the conclusion of the contract if they had taken the aforementioned
circumstances into account, or to terminate the contract in whole or in part. The claim will be brought
and dealt with as in interlocutory proceedings. Keller is entitled to suspend its obligations during the
proceedings. The Customer and Keller hereby expressly agree that an unreasonable or abnormal
increase in the prices of materials or raw materials or the prices of machine parts between the time of
conclusion of the contract and the time Keller purchases such materials, raw materials or parts shall be
regarded as a circumstance which is unforeseeable or unavoidable and for which, regardless of any
clause in the contract to the contrary, Keller has not taken the risk for its own account.
17. Liability limitation
Keller undertakes to use all reasonable means that may be expected from a careful and competent firm
to bring the order to a successful conclusion. Keller shall never be bound by a guarantee or result
Keller’s total maximum liability shall be limited to an amount equal to the price agreed upon for the order
or, in the absence of agreement on the price, the value of the work to be performed, without exceeding
the amount covered by Keller’s insurer. Keller may choose to rectify its errors, in which case no
compensation shall be due.
Under no circumstances shall Keller be liable for indirect or consequential damages. The Customer and
Keller understand that indirect and consequential damages include, but are not limited to, delays in
production start-up, business interruptions, loss of profit or turnover, loss of anticipated savings,
assembly and disassembly costs and claims against the Customer by third parties.
Keller also expressly excludes any liability due to damage to goods made available by the Customer for
The limitations on liability set out above shall apply regardless of the legal basis on which the liability
claim is based.
18. Intellectual and property rights
All intellectual property rights to the resources, creations, goods, names, drawings, including patents,
models, logos, copyrights, software and hardware, licences, company know-how applied by Keller shall
remain the exclusive property of Keller at all times and may therefore not be reproduced, used or passed
on to third parties without the prior written consent of the person authorised to represent Keller in
accordance with the articles of association. This provision shall also apply to the intellectual property
rights obtained by Keller from third parties or which Keller may exercise.
19. Credit risk – security
The Customer declares and guarantees that it has sufficient liquidity and is sufficiently solvent to pay the
price of the order. Keller is discharged from any duty to conduct its own investigations on this matter.
If Keller has serious indications that the Customer will not be able to fulfil its payment obligations, Keller
reserves the right to suspend all or part of the order until new payment terms (e.g. cash payment or
prepayment) have been agreed with the Customer and/or the Customer provides sufficient security for
fulfilment of the payment obligations. If the Customer refuses Keller’s reasonable demands, Keller
reserves the right to cancel all or part of the order. The above is without prejudice to Keller’s right to be
compensated for all damages.
20. Consequences of nullity
If one or more of these conditions should be invalid, the other conditions shall remain valid and
enforceable. The invalid conditions in question shall remain valid and enforceable in respect of the part
that passes the test of legality.
21. Law and competent court
The contractual relationship between Keller and the Customer shall be governed by Belgian law.
Any dispute between the Customer and Keller in connection with the order and its fulfilment shall be
submitted to the Enterprise Court having jurisdiction within the territory of Keller’s registered office.
