This page is a basic reference of hechsherim and kashrut agencies that appear in at least two or more products on our site. They are grouped together by their policies on yoshon.

Any hechsherim not listed, fall into the last category of their yoshon policies being “unknown”. This page provides all of their known contact information, plus any websites and/or email addresses (if they do have any).

We have provided “Click-to-Call” links (and click-to-chat) for cell phones, so generally you won’t even have to punch in a number! (The exception being if you are in the USA calling to Israel, England, or South Africa, you will have to punch in “011” first.)

If you have a question about a product’s yoshon status that is not on our site or has no current information, please contact the agency that does that product’s hashgacha. (This is also true for establishments.) They are the ones that will know if a product is yoshon or not.

Do not contact a manufacturer or establishment to ask directly if products are yoshon, as you may not get an accurate answer.

(Note: TYNI is not affiliated with, and does not endorse any of the following agencies. This page is for reference only. If you have questions about the reliability of a particular hashgacha, ask your Rav. We do not answer Halachic questions.)

Always Yoshon

These are yoshon on any product, no matter where it was made. Most are from Israel and some are from the UK.
We also have most of these in a quick reference sheet available for download on our Updates and Downloads page.
Currently, there are no agencies in the USA or Canada that we know of, devoted to being always “Yoshon-Only”.

Yoshon Only with "Yoshon" Label (Including Malt)

This group of hechsherim does include Barley Malt in their yoshon hashgacha, so everything in the product will be yoshon, if labeled as such.

All of these agencies require “Yoshon” to be printed on the package in order to be yoshon. If it doesn’t say “Yoshon” on the package, (either in English or Hebrew), they do not guarantee it is yoshon.

Wording on packages can also include one or more of the following:
ישן“, “Yoshon” or “Yashan”.
קמח ישן” or “Kemach Yashan” (Yoshon Flour).
ללא חשש חדש” or “Lelo Chashash Chadash” (Without Fear of Being Chadash).

Yoshon with "Yoshon" Label (Except Malt)

This group of hechsherim generally hold that the barley malt in flour is batel, so they do not check the status of the malt in the products they oversee.

They still require “Yoshon” to be on the package in order to be yoshon (see list below), but if you do not hold that malt is batel, you must check the dates for malt. If any of the products they oversee contain Malt, our site will state the malt cutoff date.

Acceptable package wording can include one or more of the following in Hebrew and/or English:
ישן“, “Yoshon” or “Yashan”.
קמח ישן” or “Kemach Yashan” (Yoshon Flour).
ללא חשש חדש” or “Lelo Chashash Chadash” (Without Fear of Being Chadash).

Yoshon Policy Unknown

The remaining hechsherim are those of unknown Yoshon Policy. They appear to vary in their hashgacha– sometimes being yoshon with no indications, yoshon only with a “Yoshon” label, or possibly not yoshon at all and going by date. (See above for qualifying package statements.)

For these, it is important to contact them directly to make sure of a product’s status if it is unknown. All of these have appeared in products we have on the site.
