English to Dutch Bus/Financial Law: Contract(s) Conditions of sale

Context:
"The Purchaser may resell the goods but only as the fiduciary agent of the Supplier. Any right to bind the Supplier to any responsibility or liability to any third party by contract or otherwise is however expressly negatived. Any such resale is to be at arms length and on market terms." (geen apostrof in mijn tekst)

Heb deze Engelse definitie gevonden:
"arm's length: adj. the description of an agreement made by two parties freely and independently of each other, and without some special relationship, such as being a relative, having another deal on the side or one party having complete control of the other. It becomes important to determine if an agreement was freely entered into to show that the price, requirements, and other conditions were fair and real. Example: if a man sells property to his son the value set may not be the true value since it may not have been an "arm's length" transaction."

Maar nu nog de Nederlandse vertaling... Van Dale geeft 'op een afstand, op gepaste afstand', maar ik heb het idee dat het in deze context iets anders moet zijn.

Weet niet of het van belang is, maar het betreft hier Australisch Engels (maar niet een van de teksten die via Google te vinden zijn).
