Understanding the Expiry Date for this brand. Some of Global Healing’s products are clearly marked with a Best Before or an Expiry date and others are printed with a 7 digit number that doesn’t quite look like a date but is recorded as such if you understand how to read it. The first 6 numbers are the expiry date and the 7th is the batch number. The date is applied in the American format. Example: 0508207 – 7 is the batch number, 05 is the month, 08 is the day, and 2020 is the year.
