With B2B transactions, there are no rules that apply in that regard, a very limited amount of consumer legislation applies, but in essence, with trade transactions, they can pretty much do what they please in the T&Cs. YOu essentially have no protections and certainly not anywhere even close to what you’d have as a consumer.
Even as a consumer buying spare parts there are limitations as spares are not “finished goods” therefore much of the legislation doesn’t and really can’t apply.
But if you buy on a trade account, you may as well regard it as you have no protection at all other than what’s agreed in the T&Cs/contract your account is operated on.
