This guide breaks down how the fee is calculated, who pays it, and the practical steps food producers can take to reduce their exposure.

Wholesale glass jam jars with lids are available from Jars & Bottles from as few as 3 units, with full pallet pricing at higher volumes. The most popular size for UK jam production is 251ml to 350ml with a 63mm twist-off lid.

The best glass jar for small batch chutney in the UK is a 200g jar with a 63mm twist-off lid, available from single cases with no minimum order commitment. For farmers market and farm shop producers making under 5,000 jars per year, the 200g format gives the right price point for direct sales, while hexagonal and shaped profiles give better shelf presence than standard round jars without requiring high minimum quantities. This guide covers sizes, shapes, lid options, labelling, storage, and the volume threshold at which pallet ordering starts to make financial sense.

Our 12-month analysis of 122 UK honey producers purchasing over 820,000 jars reveals clear preferences: 280ml hexagonal twist-off jars dominate with 32% market share, whilst screw-top maintains a 10.9% niche among artisan producers. Data-driven insights for scaling beekeepers.
