Can someone out there provide a clear definition of a “Mehadrin Hechsher”?

Does this mean Mashgiach T’midi? If yes, would this be at the last stage of production, or on all the raw products or perhaps only the sensitive ones?
Does this mean the Magiach who is T’midi has to be shomer torah umitzvos or does he have to be a ben Torah? Or?
Does this mean that the Mashgiach actually understands something about factories/food-production and ingredients and has been trained or is a Bochur that is burned out of learning sufficient?
Perhaps it means that if they cater to the larger (or may I dare - more lenient) community and certify Non-chalav Yisroel, then their other products – even with a ben-torah mashgiach tmidi that understands factories/food-production and ingredients stay as non-mehadrin!?

Or perhaps “Mehadrin” is not a label stating that a product is actually reliable rather it is an emotional label that the “Oilem” eat based on the “yeshivishe” equivalent of advertising and marketing that the hechsher achieves.

If “Mehadrin” is based on certain guidelines and facts, then we need to list them and research the LBD or any other hechsher for that matter, if they adhere to these guidelines or not.
On the other hand if “Mehadrin” is an emotional yeshivishe term to validate something that the “oilem” accepts based on the “oilem” accepting, then we need to research the “oilem”!!

I have seen mehadrin on a few LBD products. I think these products are generally made by a Jewish company and only sold to the Jewish community and have a different symbol on the products to the one you see on products sold to the general community.

Just to add that LBD have stricter standards for functions, bakeries and most restaurants e.g. cholov yisrael.

What does Badatz mean apart from Beis Din Tzedek? somewhat ambiguous - just check the Hechsher as Yechiel correctly pointed out

Please can you tell me any products where the LBD approves gelatin from treife animals?
Also, the LBD do not write mehadrin on any of their products. It only has the KLBD logo

I was also correcting Yodea Dovor who said LBD was Mehadrin which is incorrect as well.

Dovi, did anyone suggest the LBD was not respected? What did you add to the discussion?

The LBD certifies both Mehadrin and non-Mehdrin products. In any case it is well respected in the Kashrus field.

I live abroad and LBD is not only known as “Mehadrin” but is one of the leading hechsherim in Europe.
If you ask anyone in the kashrus field they will tell you that almost every Kosher certified product contains at least one or two ingredients certified by the LBD.
