(a) either to have the supplies brought into conformity, free of charge, by repair or replacement; 

(b) or to have an appropriate reduction made in the price. 

Any repair or replacement must be completed within a reasonable time and without any significant inconvenience to the contracting authority, taking account of the nature of the supplies and the purpose for which they are required by the contracting authority. 

The term ‘free of charge’ in paragraph (a) refers to the costs incurred to bring the supplies into conformity, particularly the cost of postage, labour and materials. 

## II.4.1.13 Assembly 

If required by the tender specifications, the contractor must assemble the supplies delivered within a period of one month unless otherwise specified in the special conditions. 

Any lack of conformity resulting from incorrect installation of the supplies must be deemed to be equivalent to lack of conformity of the supplies if installation forms part of the FWC and the supplies were installed by the contractor or under its responsibility. This applies equally if the product was to be installed by the contracting authority and was incorrectly installed due to a shortcoming in the installation instructions. 

## II.4.1.14 Services provided to supplies 

If required by the tender specifications, services to supplies must be provided accordingly. 

## II.4.1.15 General provisions concerning supplies 

(a) Packaging 

The supplies must be packaged in strong boxes or crates or in any other way that ensures that the contents remain intact and prevents damage or deterioration. Packaging, pallets, etc., including contents, must not weigh more than 500 kg. 

Unless otherwise specified in the special conditions or in the tender specifications (Annex V), pallets must be considered as one-way packaging and must not be returned. Each box must be clearly labelled with the following information: 

- name of the contracting authority and address for delivery; 

- name of the contractor; 

- description of contents; 

- date of delivery; 

- number and date of specific contract; 

- EC code number of article. 

(b) Guarantee 

The supplies must be guaranteed against all defects in manufacture or materials for two years from the date of delivery, unless provision is made for a longer period in the tender specifications. 

The contractor must guarantee that any permits and licences required for manufacturing and selling the supplies have been obtained. 

The contractor must replace at its own expense, within a reasonable time limit to be determined by agreement between the parties, any items which become damaged or defective in the course of normal use during the guarantee period.
