The combination of letters/numbers to be found on the lid is used for internal tracking purposes. Stamped onto the packaging during production, it enables us, the manufacturer, to identify where and when the product was made, thus assuring full traceability for all individual ingredients. If you ever, despite the many inspections our products go through, have cause for complaint, please do notify us. Additionally, you will find a further code on our jars and tins – the “Best before” (expiry) date. In tins, the expiry date is to be found on the lid, and on the label in the case of jars.
