A tea contract manufacturer's website rarely tells a buyer what actually matters: whether the line can run their format, whether paperwork shows up without being chased, and whether a small first order is worth the packer's time at all. Those questions only surface once a supplier is asked directly. This checklist walks through six areas worth confirming before a purchase order is written, roughly in the order a buyer needs them.
Start With Capacity, Not the Sales Pitch
A supplier's stated capacity is only useful once you know what format it applies to, because a machine rated for a simple sachet does not run at the same speed on a string-and-tag bag wrapped in an outer envelope. Ask for throughput on the specific format you need, not a general figure from a brochure. TeraVella's own bagging line, for example, runs at roughly 1,000 string-and-tag bags an hour — a concrete number a buyer can plan a delivery window around, rather than a vague "high capacity" claim. Capacity also has to be read against order size: a packer built for large retail runs may treat a small first order as filler, so ask what is committed to your slot.
Before locking in a supplier, find out how much of the format is adjustable rather than fixed to a house standard. Grammage is a good test question: a manufacturer that can only quote one fill weight is telling you their line is set up for a single product, not your brief. TeraVella, for instance, adjusts grammage within a working range, for example 1.5 to 3 grams depending on the tea. The same logic applies to blend source: can the packer run a blend you supply, or only choose from an existing herbal, fruit, black or green tea range? Neither answer disqualifies a supplier, but know which one you are buying before writing a specification.
What Documentation Should Already Be in Place
A manufacturer should be able to state its certification status in one sentence, without you having to interpret marketing language. Ask directly whether they hold ISO 9001 and ISO 22000, and whether HACCP is a standalone certificate or principles applied inside that system — the two are not the same claim. TeraVella, for example, operates under ISO 9001 and ISO 22000 with HACCP principles applied, stated plainly rather than implied. Ask the same direct question about any other certification your market requires, organic, halal, BRC, IFS or similar; silence usually means it is not confirmed.
Why the Sampling Process Tells You More Than the Brochure
The sampling stage is where a buyer learns how a supplier actually operates, long before a full order is at risk. Notice how precisely they scope a sample request: a packer that asks clarifying questions about grammage, bag format and blend before sending anything is showing the same discipline that will apply to a production run. A supplier that ships a generic sample regardless of what you asked for is telling you something too. Treat the sample as evidence, not a formality — check seal integrity, tag placement, envelope closure and print quality, the same points a finished-product inspection checks on the full run.
Communication Patterns That Predict a Smooth Order
How a supplier answers questions before an order is a reasonable predictor of how they will communicate once production starts. A manufacturer who gives direct, specific answers — a real capacity figure, a real certification statement, a real sample turnaround — is easier to plan around than one offering general reassurance. Pay attention to whether minimum order, lead time and unit cost are confirmed in writing at quotation, or left vague; vagueness at quotation tends to repeat itself at delivery.
Minimum Viable Order Logic: Matching MOQ to Your Actual Risk
Minimum order quantity is not a number to negotiate down; it reflects what changing the line over actually costs, so the more useful question is what drives it for your brief. A house blend in a standard bag and envelope generally carries a lower entry point than a customer-supplied recipe in a fully custom format, because the packer is not absorbing new sourcing and setup risk for you. If you are testing demand rather than restocking a proven line, ask whether a smaller pilot run is available even at a higher unit cost — that trade often costs less than a large MOQ on unproven demand. TeraVella confirms MOQ against the specific brief at quotation, not as one published figure.
Putting the Checklist Together
None of these six areas replaces the others; excellent documentation with no format flexibility is still the wrong fit for a custom brief, just as a fast, flexible line with vague certification answers is a risk for a regulated market. Work through capacity, format flexibility, documentation, sampling, communication and MOQ logic in that order, and most suppliers disqualify themselves on a point or two before a formal quotation. TeraVella works through this same checklist with prospective buyers, covering contract tea bag production, dried fruit packing and private label runs out of its Antalya facility.
