A buyer from a European retail chain toured our production floor two weeks ago, and afterwards, over truly terrible hotel coffee, he said something that stuck: I visit factories all year, and the thing that always decides the deal never appears in the deck. I asked what he meant. He said: the questions I actually need answered are the ones brands are afraid to let me ask.
So here they are, the five questions serious OEM and ODM buyers ask behind closed doors, answered the way we answer them on the floor, with the numbers I am allowed to publish and the honest edges of the ones I am not.
Question One: Who Is Actually Building This
The polished answer is headcount. The useful answer is the ratio.
We run with more than four hundred technical people out of total staff, which is a seventy percent share, including fifty-seven PhDs and ninety-five masters, about forty percent of R&D. Those numbers matter less than what they imply structurally: the heating curve, the firmware, the tooling and the shell engineering are decided in-house, not licensed and assembled. When a buyer asks us to move a warm-up window by three seconds, the person who answers is in the building.
The floor question to ask any potential partner, and it works on every factory in this industry: show me the last change you made to your own heating architecture, who proposed it, and how long it took to reach production. Companies that license their core technology cannot answer it. Companies that own it answer too fast, because they answer it weekly.
Question Two: What the Capacity Number Really Means
Everyone quotes a capacity. The number that matters is what happens inside it.
Our line runs at around twenty million units a year with about forty-five percent automation across production. Those two figures belong together. Capacity without automation is achievable with shifts and hands, and it produces capacity that wobbles between Monday and Friday. Automation produces the same unit at hour one and hour four hundred, and the forty-five percent figure is the honest mid-point most real factories occupy: automated where repetition punishes error, human where judgement is cheaper than a robot.
The behind-closed-doors version of this question is about peak season. Every factory in this category runs near capacity in the third quarter because every customer wants stock for the fourth. The real answer to give a buyer, and the one we give: capacity is a contract question, booked in advance, not a favour question, discovered in September.
Question Three: Why Does the Device Cost What It Costs
This is where most factory visits get uncomfortable, so we made it a standing agenda item instead.
A heating device bill of materials has four big buckets: the heating assembly, the battery, the shell, and the electronics. The heating method decides the first one hard. An induction system needs precision inserts and tight tolerances. A blade system needs the pin and the cleaning story that comes with it. A circular chamber, which is our approach in the GEN 5.0, moves the cost into geometry and tooling rather than consumables, which is why chamber devices keep landing at the accessible end of the market while matching the session quality of flagships that cost twice as much.
The question to ask any supplier: where in this quote is the money going, and what would a five-dollar reduction cost the product? A factory that cannot answer has not designed the device. A factory that answers immediately usually says: the shell, or the battery, and then explains what that trade does to your brand. Shell cuts show up in returns. Battery cuts show up in reviews. Neither is where a new brand wants to learn economics.
Question Four: What Happens When Something Fails
Warranty rates get quoted in single digits and nobody believes them, correctly, because they depend entirely on what the factory counts.
The useful version is a failure-tree question. Ask what percentage of field failures are battery, what percentage are the heating assembly, and what percentage are user damage the factory lumps into "other". Then ask what changed in the last twelve months because of that tree. On our line the battery is a two-thousand-milliamp cell chosen less for capacity than for cycle stability, because a device that loses twenty percent of its capacity in year one generates more support cost than a slightly larger cell ever saves. That reasoning, not the spec sheet, is what a buyer is actually buying.
And ask for the boring documents: the certifications for the markets you sell in, current and dated. Any factory can show a logo wall. The dated certificates matching your target market, checked against the notification databases, are the difference between a shipment that clears customs and one that becomes a warehouse story.
Question Five: What Will You Not Build for Me
The closing question, and the one that took our visitor by surprise.
Every capable factory has a list of things it declines. Ours includes projects that want our chamber architecture rebranded with a spec we know fails, devices priced below a floor where the battery quality collapses, and anything where the client wants to skip market certification to hit a launch date. Declining work is expensive and we do it anyway, because every failed device in the field advertises for us negatively, and negative advertising compounds.
Ask the question of any partner and listen to how fast the list arrives. A factory with no refusals is a factory whose quality floor is wherever your budget happens to stop. A factory with a specific, boring, explained refusal list has thought about what its name can survive, which is exactly the risk profile you want holding your tooling.
The Side-by-Side, Factory-Visit Edition
| Buyer concern | What brochures say | What to actually verify |
|---|---|---|
| R&D strength | Engineer headcount | Ratio, and a real architecture change |
| Capacity | Annual units | Automation share, Q3 booking terms |
| Price | Floor price per unit | Where a reduction bites the product |
| Reliability | Warranty rate | Failure tree, dated certificates |
| Partnership | "Flexible, full-service" | What they refuse, and why |
None of the right-hand column appears in a brochure, which is the entire point of the visit, and of this article.
Why We Write This Down at All
Some colleagues think publishing the hard questions is handing ammunition to competitors. My view is the opposite. The buyers who fly in to walk a floor already know these questions. The ones this article is for are the first-time brand owners about to learn factory economics through an expensive mistake, and those are precisely the partners a factory should want.
If you are evaluating manufacturers for a heated-tobacco line, bring the five questions and see who flinches. If you want to see the answer sheet we send back, it starts at heatxlab.com/products, and the factory tour starts with a flight and ends with the terrible coffee. Bring the questions. A good factory will thank you for them, and a great one will have a failure tree ready before you finish asking.
