A best-before date looks like the smallest line on a tea carton, yet it is one of the few claims a brand makes about the future. Get the underlying logic wrong and the consequence is not a fine — it is a customer who opens a pack after eight months and finds a cup that tastes of cardboard, then leaves a review saying so. This piece looks specifically at how that date is set, who owns the decision, and why the storage line printed beside it matters as much as the date itself.
Best-before and use-by describe different promises
The two terms are often used loosely, but they mean different things. A use-by date is a hard safety limit, typical of chilled or highly perishable foods, and the product should not be sold or consumed after it passes. A best-before date is a quality claim: the manufacturer is saying the product will still perform as expected up to that point, and after it the food is generally still safe but may not be at its best. Dry tea sits squarely in the second category, and confusing the two on artwork creates avoidable friction with retailers and marketplaces.
Why tea is dated on quality, not on risk
Dried tea and dried herbs do not support the kind of microbial growth that drives a use-by date. What happens over time is slower: volatile aroma compounds diffuse out of the leaf, ambient moisture works its way in, and colour and flavour drift. None of that makes the tea unsafe on a realistic shelf-life horizon; it makes it duller. That is why the date belongs on the label as a best-before promise, set against how quickly a specific pack loses freshness rather than against any safety threshold.
For a private label brand, it is tempting to treat the date as a detail to fill in on the artwork template. In practice it has to come from the manufacturer that blends and bags the tea, because only that party has visibility into the raw material condition, the packaging barrier and how earlier runs have actually held up. A brand can and should ask why a figure was chosen, but inventing a longer date to match a competitor's carton, or a shorter one out of pure caution, both create problems: one risks stale stock still on shelf, the other discards good product unnecessarily.
The date belongs to the pack, not just the leaf
Two batches of identical tea can honestly carry different best-before dates if they are packed differently. A blend sealed into an individually enveloped bag inside a film-wrapped carton is protected on more fronts than the same blend in an unsealed paper envelope in an open box, and the date should reflect that rather than a single figure applied across every format a brand sells. A private label brief needs to specify the exact bag, envelope and carton construction before a shelf-life figure is agreed — the packer cannot responsibly commit to a date for packaging that has not been defined.
Storage wording is part of the claim, not decoration
A best-before date is conditional, even though the carton does not spell that out. It assumes the product is kept somewhere reasonable — away from direct heat, damp and strong-smelling neighbours such as spices or cleaning products — for its whole life on the shelf and in the buyer's kitchen. Printing a short storage line next to the date, rather than burying it elsewhere, tells the buyer what the promise depends on, and gives the brand a fair answer if a complaint traces back to a hot warehouse rather than to the tea itself.
When an old date can no longer be trusted
A best-before figure is only as good as the conditions it was calculated for, so it needs revisiting whenever those conditions change. Switching envelope material, moving from an unlined to a lined carton, adjusting the fill weight, changing the source of a dried fruit inclusion, or moving production to a different site are all reasons to re-check the date rather than carry the old one forward on new artwork. Treating the date as fixed once it is chosen is how brands end up making a promise their current packaging can no longer keep.
Putting it on the artwork correctly
Once the figure is agreed, the mechanics matter almost as much as the number. The date is normally printed at the packing line rather than baked into static artwork, alongside the lot code, so the same design can serve multiple production runs without reprinting. Confirm the format, the print position and where it needs to remain legible through shipping with whoever runs your line before the design is locked. TeraVella packs herbal, fruit, black, green and customer-supplied tea blends into string-and-tag bags under ISO 9001 and ISO 22000, with HACCP principles applied, and can talk through packaging and dating specifics — for tea or for a private label dried fruit line — at the quotation stage.
