Lot Number Expiration

How do I read a LOT number and determine the expiration date of a particular product?

All oral care products and carrier oils will include a printed expiration date after the LOT number.

LOT numbers are printed on each and every product we produce at our factory. This number indicates the date the item was produced and is printed small in yellow ink above the label and below the lid.

The standard format for our LOT numbers is the following:


S = letter code that indicates the batch or shift

YY = the last two digits of the year

JJJ = the Julian date of manufacture

*EXP MM/YYYY = expiration date of shelf life

TTTT = timestamp of manufacture

*Not all products have a printed expiration date

Our products have a shelf life intended to last two years from date of manufacture, which can be determined by reading the lot code. We recommend that products be used within 12 months after opening. Most of the time, the products can last much longer if stored properly in a cool, dark place since most of the ingredients we use have a very long shelf life - but factors such as air/heat/light/time can slowly deteriorate the quality of a product.

For products that include a single ingredient (essential oils, carrier oils, etc), these can last much longer if stored properly. These items include a period after opening symbol on each label.

If you have a lot code that appears different from this code or are unable to read a code, please contact us and we’d be happy to help confirm the expiration date.
