Producten binden: de verkoop van één product of dienst conditioneren bij de aankoop van een ander product of een andere dienst Probeer geen overeenkomst van een klant te verkrijgen dat deze alle vereisten van een bepaald product uitsluitend bij Avient zal kopen, dat deze exclusief met Avient zal handelen of dat deze geen concurrerende producten zal kopen of anderszins zal handelen, tenzij u de voorafgaande goedkeuring van de Juridische Afdeling van Avient hebt om dit te doen. Vereis ook niet van een klant om een product of dienst te kopen als voorwaarde dat u de klant een ander product of andere dienst verkoopt zonder de voorafgaande goedkeuring van de Juridische Afdeling van Avient. 13.
