Golders greener, i think you mean to say that thay do NOT go to the factore on a yoitzei ve’nichnas for approved products.
If you meant something else pleasse explain.
Popa, i can only rely on what i see over here and have heard from other european sources, but as i far as i have understood, the approved label, or lists, in europe, does not necassarily mean that they feel that it does not need hashgacha, but simply that according to the basic information they have they cannot see a problem. I am unaware if and when they actually visit a factory, but i found it hard to beleive that every hasahgacha has sent their own people to every factory on the list. Perhaps they rely on each other.
The reason for this is that the kosher consumer market is simply not big enough in europe to encourage any major producer – such as drambuiee – to agree to full certifiacation.
I am unaware of the requirements os shulchan Oruch, and what is needed.
Numerous people have assured me that they no self respecting hechsher uses complicated ingredients from their lists for fully supervised products, with the exception of sugars etc..
No offence meant, but to suggest otherwise is being ???? ??? on many choshuve european poskim – including R’ Chanoich ehrentrau shlit”a, and R’ heinoich Padwa zatza”l.
I have also been told that many of these rabbonim themselves do not rely on their lists, in fact apparently R’ Ehrentrau does not even carry in his own eiruv,
