Version 1 | January 2, 2019

1. General clause:

This contract reflects the sales conditions set between "Manufacturados Españoles de Resinas Fluoradas SLU" (hereinafter MEREFSA) and THE CLIENT, and implies the acceptance of all the terms reflected here, no condition reflected by the client being valid in any other document except MEREFSA express signature. This includes any general condition sent by the customer when accepting the order, attached general purchase conditions or other conditions that are reflected in web registration operations indicated by THE CLIENT. The data received by the clients will be considered as suggestions to facilitate the negotiations, but in no case constitute their acceptance unless there is an express signature by the legal representative of MEREFSA.

2. Offer validity and production start requirements:

The products to be served, as well as their characteristics are those reflected in the MEREFSA offer document, independently of the initial information provided by the client that could vary in subsequent communications. Technical advice, whether verbal, in writing or through essays, is given in good faith but does not relieve the client of the obligation to verify its validity by accepting the offer.

The orders will be managed once the agreement of the offer has been received together with the proof of payment if applicable.

Confirmations of offers once they have expired, or that imply prior payment and that are later than the validity date, will not be considered valid. However, MEREFSA reserves the right to respect these conditions even if it has expired if it deems it appropriate.

The indicated deadlines will be considered valid once all the relevant aspects have been managed and the order confirmation is sent to the customer. This confirmation will be made once the established payment method has been verified, being a reason for refusal not to have credit by the MEREFSA risk insurer or not to have the corresponding bank note depending on the established payment method.

Changes or cancellations on the accepted offer are not guaranteed, notwithstanding that MEREFSA will always make its best efforts to review its viability and provided that the raw materials necessary for its manufacture have not been produced, prepared or purchased.

3. Payment and financing:

The customer accepts the payment method indicated in the offer and undertakes to strictly respect it. MEREFSA reserves the right to change it unilaterally in case of breach of this in previous commitments, or in case of failure to comply with the agreements reflected in the document "Acceptance of payment method".

All expenses and commissions generated to make the payment of the offer or the invoice will be paid by the customer.

In case of prior payment, the acceptance of the offer will not be considered effective until receiving the full income indicated.

In case of non-compliance with the payment method, MEREFSA will pass on to the client all the expenses incurred and reserves the right to charge interest up to the legal maximum allowed for the delays produced.

If the manufacture of tools or molds is necessary, prior written and express acceptance of the part plan provided by MEREFSA will be required.

MEREFSA may pass a "Participation" price on the client for design, advice and production start-up tasks. This price will be expressly reflected in the offer. The tools will always be owned by MEREFSA and may be published on our website.

Homolotacion: A new tooling will always require the approval of a first production sample. This will be understood automatically by MEREFSA as long as the sample meets the dimensional tolerances indicated in the part plan supplied to the customer. MEREFSA may require the express acceptance / approval by the customer of a first manufactured sample and before making the overall manufacture of the order. Such approval may be made through the sending of documents (showing photos, dimensions or specific elements of the product) or physical shipment of the manufactured sample to the customer. To facilitate the homologation tasks in the MEREFSA facilities, it is always advisable to know the final application of the product and even that the customer provides those parts where the product to be manufactured will be housed. Since, depending on the type of material and its elastic properties (as in the case of Silicones), the exact position of the workpiece plane cannot be guaranteed even when the reflected dimensions are met. In case of not having this accommodation, it will be the responsibility of the client to check it, the return being not acceptable for that reason.
