7. Introduction

7.1. Functioning. The Marketplace allows potential Buyers and Sellers to meet virtually and to conclude transactions. The Platform is organised in such a way as to offer the greatest possible flexibility to contracting parties. Usually, the order process via the Platform comprises:

  • Publishing and consulting Advertisements (see Articles 8.1 and 8.2)
  • An exchange and verification phase (document check and/or Product tests) (see Article 9);
  • Arranging a contract on the Transaction (see Article 10);
  • Selecting Options (e.g. ADR documentation or Transport of Products) (see Article 13); and
  • Signing of the Contract by the Parties.

7.2. Participation in the Platform. Users are free to organise the transaction flexibly via the Platform. By registering on the Platform and accepting the T&Cs, Users undertake to conduct the Transaction in its entirety via the Platform. In particular, it is prohibited to buy or sell advertised Products outside of the Platform.

8. Advertisements and orders

8.1. Advertisements. Through the Marketplace, WaVa allows Buyers and Sellers to publish advertisements concerning offers to sell or buy Products (Advertisement). Advertisements must comply with the specifications published on the Platform and only refer to Products that are authorised for trade on the Platform. The Products must be described in the Advertisement supplied by the User, who is solely responsible for its content (see Articles 4.4 and 19.4). By sending us the data relating to the Advertisement, the User consents to this advertisement being published by Wava on the Marketplace (including its non-public content to Users who have undertaken to treat the information as confidential in accordance with Article 8.2).

8.2. Consultation of Advertisements. Any visitor to the Platform can consult the public content of Advertisements, which contains general information. In order to consult the full content of an Advertisement, the User concerned must have (i) connected to their User account beforehand and (ii) confirmed that they undertake to treat the information contained in the Advertisement as confidential; only to access the content with a view to concluding a Transaction concerning the Products in question; and in particular, not to disclose the content of the Advertisement to third parties.

9. Document check, samples and tests

Users interested in a Transaction can exchange additional information via the Platform and carry out document checks, which the potential Buyer may demand, as well as conducting sample analyses. If requested to do so, WaVa can assist the Parties in this context, in particular by organising the transport of samples. Otherwise, the Users concerned are solely responsible for these operations.

10. Order and contract arrangements

10.1. Order. After the necessary checks and verifications have been carried out satisfactorily, the Buyer can place an order via the Platform, in which case the Seller is notified on his/her User account and by email.

10.2. Contract arrangements. If the Seller confirms the Buyer’s order, the two parties will receive a link that allows them to view and sign the order form and contract concerning the Transaction (the Purchase contract) entirely electronically.

11. Price and payment

11.1. Price. The prices of Products listed for sale on the Marketplace are freely set by the Seller, in line with the applicable legislation. Prices are in principle stated in Swiss francs (CHF) for Products purchased in Switzerland, and in euros (€) for Products purchased in the European Union. Prices are net and include VAT if applicable.

11.2. Fees. The prices indicated on the Platform do not include transport charges, or any potential foreign taxes, customs duties, insurance fees or other charges. If the Buyer opts for transportation via our External Partner, the transport costs will be added to the price and indicated in the contract (see Article 13.3). 11.3. Financial flows. All transfers of funds between Buyers and Sellers are conducted outside of the Platform and in accordance with the Purchase contract. When the Purchase contract is signed, WaVa will invoice the seller the amount due for any options and the Commission, as set out under Article 11.5 T&Cs. 11.4. Payment. The payment of Products, as well as any Optons selected, is made by bank transfer in accordance with the terms set out in the Purchase contract. 11.5. Commission. Registering on the Platform as a Buyer or Seller is free of charge. WaVa receives a commission (the Commission) on the amounts of transactions conducted via the Platform, which corresponds to 20% (excluding applicable taxes) on the transaction amount. The Commission is due on all Transactions, irrespective of the relations between the Buyer and Seller, and remains due, in particular in the event of a dispute between the parties concerning a Transaction.

12. Delivery and risk transfer

The delivery of Products is organised, and the risks are transferred, in accordance with the provisions agreed between the parties involved in the Purchase contract. You acknowledge that WaVa does not bear any risk of loss, theft, delay, or any other damage associated with delivery of the Products.

13. Optional services

13.1. Introduction. In order to facilitate the execution of Transactions, the Platform allows Buyers and Sellers to select certain Options when drawing up the contract for the Transaction. These options are detailed on the Platform and may include:

  • preparing transport documentation;
  • transporting the Products;
  • producing external anaylsis certificates for Products.

13.2. External Partners. WaVa has selected third party service providers to whom it entrusts the delivery of the Options (External Partners). In this way, on request of Users, WaVa can put Users in touch with the External Partners that are best able to meet their requirements.

13.3. Contract. If the offers submitted are approved, an agreement is concluded directly between the selected External Partner and the User(s) involved, in accordance with the conditions applied by the External Partner.
