Bottles produced from January 2022

The YYWW and MMYYYY formats are superseded by a new, more precise DDMMYYYY format which displays the expiration date instead of the production date.

The batch number remains in use, in the same form, but it is placed on a separate line alongside the expiration date.

Where to find the expiration date:

On a 250ml bottle: Batch number and expiration date are laser printed onto the upper part of the bottle.
On a 1-litre bottle: Batch number and expiration date are engraved onto the bottom part of the bottle.
On a 2.8-litre can: Batch number and expiration date are laser printed onto the bottom part of the can.
On a 5-litre can: Batch number and expiration date are laser printed onto the bottom part of the can.
On a 17-litre bin: Batch number and expiration date are laser printed onto the bottom part of the bin.
On a 180-litre barrel: Batch number and expiration date are located on the label on the lid.


The expiration date depends of the product. Earlier, the shelf life of Polarshine compounds has been 2 years from the marked production date.
This has now been expanded to 3 years for the following Polarshine products: 20, 15, 12, 12 Black, 10, 8, 5, 3, Liquid Wax, E3 and Polarshine 45.
The shelf life of Polarshine 35 and 25 remains at 2 years.


Earlier styles of marking the batch number and expiration date

Bottles produced from 1st of October, 2019
For clarity, the production date is changed from YYWW to MMYYYY format.

A typical production date will now read 092019.

Bottles produced before 1st of October, 2019
The bottle is marked with a batch number and a production date in YYWW format, which consists of the last four digits.

For example, if the numbers are 1938, that stands for week 38 of 2019.
