In general, call the Rav of the local frum shul, explain your standards and respectfully inquire about the vaad and if this would be equivalent to what you have in your local area.

If you do not know enough about kashrus, especially industrial kashrus, to make an informed judgment, ask your rav. Many rabbanim, especially in EY, will call a local vaad or rabbanut for you and tell you if it’s to your standards.
