The build decision: four paths, four sets of questions
You have a product plan, a target market, and a launch date. The factory question is where the plan usually stalls.
Four paths exist. One coarse rule sorts them: retrofit when you own a plant that ran a similar process, build when you own nothing and need long term volume, contract when you have no tobacco experience, convert when you already run electronics assembly.
Build new. You commit to full capex and a construction schedule. BAT chose this in Romania, an EUR 800 million program that includes a completely new manufacturing hall dedicated to its glo consumables [1]. The money and months go less into machines than into the site itself: feasibility studies, approvals, the structure, utility connections. Ask: can the capital plan survive a regulatory delay?
Retrofit existing space. Under the right circumstances, brownfield development can significantly speed up new capacity and reduce capital requirements [2]. The mechanism: an existing plant already has utility hookups, walls, and often permits, so you skip the studies and approvals a greenfield site starts from zero. In May 2021 BAT said heated tobacco production would start in Kanfanar [3], a cigarette factory BAT had bought under a deal that obliged it to keep production at the site. BAT put more than EUR 80 million into upgrading that plant instead of building a new one [3].
But a retrofit is only as good as the building’s envelope. An HNB line runs two environments in one building. On the electronics side, stray particles become solder defects and short circuits, so the heater assembly wants a cleanroom. On the tobacco side, heat above the material’s window changes the sheet itself, so blending and storage want temperature control. Both are structural demands: they need floor loads, power feeds, and HVAC capacity the building either has or does not. That, not distance, is the retrofit’s first question.
Contract an existing HNB maker. You skip the build entirely. Ask about capacity slots and certification history, and settle the flavor formula before work starts: whoever pays for it owns it on paper, and that ownership decides whether you can move production elsewhere later.
Convert a mature electronics line. Machine builders now sell full THP equipment ranges, from recon tobacco primary processing to base rod making and final combining [4]. Your assembly floor covers the electronics side; the tobacco-specific stages are the gap, so price them separately before you commit.
We sit on the supplier side of the last two paths. Joint factory establishment and production line supply are two of our nine commercial models, and we build new capacity in six months versus two to three years for conventional sheet technology. The rest of this guide walks the decision in order: regulation, heating route, patents, factory floor, contract, cost, traceability, market access, vendor checks, stage gates, and risk.
Where the regulatory fork splits: HTP is not an e-cigarette
A heat-not-burn product can legally be a cigarette. That one sentence from the FDA does more work than most factory checklists.
The product-level difference is simple. Heated tobacco products heat actual tobacco leaf. By contrast, e-cigarettes heat liquids that typically contain nicotine derived from tobacco, as well as flavorings and other ingredients [5]. The regulatory consequence follows from that difference. If a product meets the legal definition of a cigarette but the tobacco is not heated to a temperature high enough to cause combustion, the FDA categorizes it as a non-combusted cigarette and regulates it as a cigarette [6].
The industry has already seen what happens when regulators arrive after the products. In 2009 the FDA blocked e-cigarette imports by classifying them as drug delivery devices. A court ruled in December 2010 that the agency could regulate them as tobacco products, not drug devices [7]. The deeming rule followed in 2016.
For a factory decision, the fork matters concretely. It decides which manufacturing standards, labeling rules, and market entry filings apply to your line. It also shapes product strategy: our zero-nicotine herbal line exists for markets that restrict nicotine-containing e-liquids, such as Japan.
Exemptions that can be withdrawn
Treat regulatory exemptions as a default state, not a right. The EU wrote the withdrawal mechanism into law.
Delegated Directive (EU) 2022/2100 lets the Commission withdraw a heated tobacco exemption for a particular product category if there is a substantial change of circumstances, as established in a Commission report [8]. The mechanism works. The EU flavor ban has applied to heated tobacco products since October 23, 2023 [9].
That timeline exposes the real problem. A flavor ban can land two to three years into your capacity investment, while a factory depreciates over five to ten years. The exemption is revocable by design, so your plant outlives the promise.
The hedge is not in the factory. It is in the contract. A flavor ban rewrites your SKU mix, and your SKU mix defines how much material your full-supply partner must hold and how flexible the line must be. Write regulatory events into the material termination clauses before the ban arrives, not after.
We see this play out among customers. E-cigarette brands hit by flavor bans and pivoting into HNB are a recurring scenario in our project pipeline.
Heating route decides the BOM
Your bill of materials is decided the day you pick a heating route. Everything downstream, from the materials contract to the line layout, follows.
Heated tobacco has two main routes, and PMI has shipped both. Its early generations, the blade THS sold as IQOS 3 and IQOS ORIGINALS, heat the tobacco through internal resistive heating. The newer route, internal induction, puts a susceptor at the core of each tobacco unit [10]. Blade heating is fast, but the blade’s printed circuitry on a ceramic substrate breaks easily and is hard to clean; overly rapid heating also tends to cause uneven heating [11].
The induction route makes the susceptor a custom, patent-heavy part. One PMI susceptor patent family alone has 12 family members spanning the US, Europe, Korea, China, Japan, and Russia [12]. If you build or buy this route, the susceptor is your long-pole material.
Parameter ranges are not background reading. They are contract text. Homogenised tobacco in heated articles has an aerosol former content of greater than 5% to about 30% [13], and glycerin aerosol former is incorporated into reconstituted tobacco sheets at a temperature below about 40 degrees C [14]. Write both ranges into your supplier spec, or you have no pass/fail test.
Consumable generations move. Newer heated tobacco consumables pair a first and a second aerosol-generating substrate on one combining paper [15], which means your line needs process flexibility and your equipment contract needs a compatibility clause. Reconstituted tobacco sheet remains the quiet technical barrier on the consumable side.
This is where we work. Our susceptor is a single iron-nickel-zirconium alloy sheet that heats, self-limits temperature, and identifies itself to the device, replacing laminated multi-layer stacks that are extremely hard to press to roughly 0.06 mm. One piece of material does all three jobs: its magnetic permeability rises then falls with temperature and collapses at the Curie point, so it heats fast and caps itself, and the device reads its magnetic signature for authentication. In our measurements it reaches draw temperature in 10–12 seconds, holds 12–14 puffs, peaks at about 325.1–339.8 degrees C, and delivers aerosol at about 39–42 degrees C. We are the only supplier whose susceptors achieve 90%–100% recognition rates in induction-heating devices.
The patent ceasefire and what it means for new capacity
One non-monetary settlement covered an import ban. Hold onto that fact.
In February 2024, PMI and BAT settled every pending patent case worldwide. The settlement is non-monetary, runs eight years, dismisses all pending patent infringement cases, and blocks future claims against current products [16]. It also covers the existing US import ban on IQOS, which a PMI filing said the parties would ask to be rescinded [16]. JTI took the same road earlier, buying heat-not-burn patents from Ploom [17].
The lesson for new capacity: patents can close or reopen a market, and they attach to the production line itself. The PMI susceptor family claims both the susceptor assembly and the aerosol-generating article that contains it [12]. A line you buy may include tooling that sits inside someone else’s claims, so check your equipment supplier’s freedom to operate before signing.
We run the same check on ourselves. Our sticks are patent-safe, built on 30+ inventions and PCT filings backed by FTO analysis.
Two gates before you buy a production line
A USD 10k–30k search hedges a factory and an injunction. The asymmetry should end the budget debate.
A freedom to operate search costs anywhere from $10,000 to $30,000, and often beyond [18]. The production line it protects costs far more, and a post-launch injunction costs more than both. You do not need a big company budget to start. Even for a limited budget, a targeted review will often identify most of the risks of possible patent litigation, and those risks can be dealt with through design-around, an invalidity review, or a non-infringement analysis [19].
Search twice. Product patents and line-material patents are separate questions. PMI’s susceptor family claims the susceptor assembly itself and the article that contains it [12], so one FTO file does not cover both your stick and the tooling that makes it. Gate one: clear the product. Gate two: clear the line and its fixtures.
Then lock down the molds before production starts. In many standard manufacturer agreements, tooling ownership defaults to the supplier, which lets the supplier hold your molds hostage if you try to move production [20]. Write the opposite: tooling paid for by you belongs to you, and the supplier holds it as a bailee, meaning temporary custody for production purposes while ownership stays yours [21].
FTO-verified designs are the foundation of our patent-safe positioning.
Two standards in one building
One HNB factory budget has to satisfy two standards systems at once. The split runs straight down the middle of your product: electronics on one side, tobacco material on the other.
The electronics side is a cleanroom question. ISO 14644 classifies cleanrooms by particle counts at threshold sizes from 0.1 µm to 5 µm [22]. A working example from EMS: Intretech runs its high-speed SMT lines in ISO 8 clean rooms at its Hungary plant [23].
The tobacco side is a temperature question. When glycerin aerosol former is incorporated into a reconstituted tobacco sheet, it is added at a temperature below about 40 degrees C [14]. Exceed that window during blending or casting, and you change the sheet itself.
The third constraint is consistency, and it is solved on the line, not in the incoming material. One heating device patent describes the standard: each heating element is individually calibrated, so that dispersions of the characteristics of the heating elements, and of all the components involved in the computation of electrical resistance, are compensated for [24]. Same idea, different stage: burn-in testing forces weak units to fail in-house and filters out infant mortality failures before they ship [25].
Before you approve any line item, ask what quality target it serves. If nobody can answer, cut it.
What full material supply actually transfers
Full material supply is not a shopping service. It is a transfer of three things: ownership, cash, and risk. Read the clause with that lens.
Ownership moves first. In a turnkey model, the factory sources, purchases, finances the inventory, and stores the material [26]. That stock is the factory’s, and its carrying cost is the factory’s problem until units ship.
The factory also fronts the cash, and it prices that service. Turnkey pricing is component cost plus a material margin [26]. The terms that shape your real cost sit beside the unit price. Minimum order quantities are one of them. In disposable vapes, a useful scale reference, MOQs run 10,000 to 50,000 units per flavor [27]. Treat that as the order of magnitude, not the HNB number.
Risk moves last, in percentages. Turnkey factories absorb standard scrap of about 0.5%; passives add 2% to 5% for tape and reel leader waste; high value ICs add 0.5% or exactly 2 units, whichever is greater [26]. In the opposite model, consignment, the customer owns the inventory 100% of the time and pays no material markup [26].
One more question separates real full-supply partners from assemblers: who makes the materials? Our own material matrix covers cast-leaf sheets, tobacco extracts, cut stems, susceptors, and devices, and we keep minimums low on both raw materials and white label orders.
Three clauses worth more than the rest of the contract
Every flexibility clause has a termination condition. Read it first.
Excess and obsolete inventory. E&O liability-sharing is a recurring subject in OEM-EMS relationships, and consulting work on related damages often starts there [28]. The scale is not small. A single end-of-life notice can immediately tie up millions of dollars in working capital for multiple years [29].
Last-time buy and buffer clauses. Read the case law before you trust the buffers. In Solectron v. Trimble, the manufacturing services agreement said plainly that “any flexibility or buffer arrangements agreed to by the Parties hereunder shall be terminated upon EOL notification” [30]. Buffers exist until the moment the supplier sends a notice. In consumables with many SKUs, our experience says to check E&O granularity line by line; a blanket clause rarely matches how flavor-by-flavor demand actually dies.
Tooling ownership. Standard manufacturer agreements often default tooling ownership to the supplier, which converts your molds into a hostage if you move production [20]. One sentence fixes it: molds developed for your product and paid for by you belong to you.
The pattern across all three: value hides in the termination conditions, not the headline terms. Every buffer promise should be followed to the sentence that kills it.
Consumables are a materials game
For a tobacco sticks plant, raw materials run 55–65% of operating expenses [31]. Your negotiation center on this side is the material price, the material margin, and the minimums.
Add the border. The real unit cost of an international order is the landed cost: product price plus duties, taxes, and other export or import fees [33]. Compare suppliers on that number, not the invoice price.
And keep an eye on substitution. Supplier terms exist that prohibit deviating from control plan requirements, material specifications, or designated sources without approval [34]. Put the same sentence in yours.
On the consumable side, our process cuts customer cost by about 20% versus competitors.
Traceability is not paperwork
2.6 million units came back in one e-cigarette recall. That is the scale a traceability system has to survive.
The EU requirement is blunt. All unit packets of tobacco products must be marked with a unique identifier [35]. Cigarettes have lived with this since May 20, 2019; all other tobacco products, including heated tobacco, since May 20, 2024. The identifiers come paired with security features, operators must record packet movements and transmit them to an approved data storage provider, and the tracking data lets authorities determine when a product was diverted into the illicit market [35].
The recall side shows why this is a factory design question, not a back-office one. R.J. Reynolds recalled about 2.6 million Vuse Vibe power units nationwide after batteries malfunctioned and overheated [36]. That was an e-cigarette, not HNB, but the mechanics are identical. Without a material-batch to finished-batch chain, you cannot say which line, which supplier, or which lot failed. With one, a manufacturer that underwrites recall compensation can pass those costs to the supplier whose fault it was [37].
Code the whole chain before you pour the floor. Marking stations, identifier data structure, and reporting interfaces are layout decisions.
Market access is bound to your factory
USD 2.5 million, officially. Up to USD 100 million, actually. That 40x spread is the PMTA cost range for a US application [38]. And the evidence lands on your factory floor.
The FDA shows up. An in-person tobacco manufacturer inspection is required, and it confirms whether current Good Manufacturing Practices are in use and reviews your SOPs and document control [39]. The chain of proof lives in your plant: batch records, calibration logs, line settings.
Costs compound. One e-cigarette brand’s PMTA process was expected to cost over USD 20 million [40]. Different product class, same order of magnitude.
Changes can restart the process. Under 21 CFR 1114.39, if the FDA finds a product change goes beyond the scope of the marketing granted order, the applicant must submit a new PMTA or a supplemental PMTA to market the changed product [41]. A factory change can be that change.
Know which layer each certification audits. ISO 13485 evaluates the management system used to design and manufacture devices, not the device itself [42]. CE, RoHS, REACH, and EMC certifications assess the finished product [43]. PMTA examines both, product and manufacturing system together. And the compliance burden is shared: the FDA treats the brand owner and the contract manufacturer as equally responsible for how the product is made [44].
Put three things in your contract: inspection cooperation duties, ownership of the data the factory generates, and a change-notification clause. We cover the assistance side in our turnkey scope, including TPD and JFRL compliance support, and we hold MSDS, TPD, JFRL, ISO 9001, ISO 14001, and GMP among our credentials.
The HNB-specific vendor checklist
Three extra checks filter out most bad HNB suppliers. Run them after the generic screen.
The generic screen stays first: headcount, tools, and skills, checked item by item [45].
Check one: formula disclosure. A reconstituted sheet or aerosol former supplier should hand you a formula window and a process window. An aerosol former content of greater than 5% to about 30% in homogenised tobacco [13] is a concrete, pass/fail benchmark. A supplier who cannot state their window is hiding it.
Check two: consumable-device compatibility. Recognition rate and fit are integration items, not separate deliverables. Make them a joint acceptance test in the contract.
Check three: patent status. Ask whether the material supplier’s right to supply is clean, because a susceptor maker with a murky FTO position becomes your problem the day your line ships.
Then verify the building. Most third-party auditors give suppliers 72 hours notice; the sturdier method is unannounced arrival, confirming the date the night before and walking the production floor before the first shift to see actual workers, active machines, and in-process orders [46].
One red flag from our sourcing experience: a tobacco material vendor that cannot produce an MSDS or a composition disclosure. Treat that as a stop, not a negotiation point. To our own OEM/ODM customers we offer the mirror image: NDA and IP protection commitments from day one.
Two tracks, one gate
Your device passed PVT. Your consumable formula is not finalized. You are still at the gate.
HNB development runs two tracks in parallel. The device track follows the electronics rhythm: EVT validates engineering feasibility with 10–40 units over about 5 weeks, DVT validates the complete design with 50–100 units over 6–8 weeks, and PVT validates the production process, repeatability, and readiness to build the approved design consistently at scale, about 3 weeks [47]. Those are generic consumer electronics benchmarks. The consumable track runs on its own clock: formula scale-up, sensory sign-off, stability.
The two tracks meet at one integration gate, and that is where HNB projects break. A device change can invalidate the aerosol behavior you just signed off; a formula change can push the heating profile back an entire stage.
Then freeze, and protect the freeze. Changing the BOM after the declared freeze date cancels existing orders, incurs vendor restocking fees, and starts a new quoting cycle, delaying launch by weeks [48]. In regulated product classes, every change after design freeze falls under regulatory oversight [49]. During ramp-up, expect low yields: the new process is still being learned, and yield and production rate trade off in the short run [50].
Acceptance is not one good batch. It is consecutive batches with consistent COAs. For calibration, we run 1–2 months from sample to small batch and 4–6 months to mass production.
Four risks, four hedges
Four risks. Four hedges. No empty advice.
Regulatory shifts. Write regulatory events into your material termination clauses. The EU created a mechanism to withdraw heated tobacco exemptions on a substantial change of circumstances [8], then used it when the flavor ban reached heated tobacco in October 2023 [9]. Name the event class in the clause, not the specific law.
Patent injunctions. An import ban closed the US market to IQOS before the 2024 settlement [51]. Hedge with FTO clearance and design-around before the line ships, not after.
Recalls. Recall coverage tacked onto a product liability policy often arrives as a sub-limit with limited coverage; a standalone recall policy is the more complete hedge [52].
Market concentration. KT&G pairs a demanding Middle East market with a less regulated Indonesian one, using local partnerships in each [53]. That is one company’s configuration, not a universal rule. Still, a two-market pairing with different regulatory profiles is a hedge worth designing for.
On the patent side we bring our own evidence: we serve 42 countries with zero patent disputes.
FAQ and next steps
Is heated tobacco regulated as a cigarette in the US?
Yes, when it fits the definition. Heated tobacco heats actual tobacco leaf, where e-cigarettes heat liquids that typically contain nicotine derived from tobacco, plus flavorings and other ingredients [5]. If the product meets the legal definition of a cigarette but stays below combustion, the FDA regulates it as a cigarette, and that sets the manufacturing standards and market entry filings for your line.
What does full material supply mean in HNB manufacturing?
The factory sources, purchases, finances, and stores the material, and it carries the scrap risk: 0.5% standard scrap, plus add-ons for passives and high value ICs [26]. Ownership, cash, and risk move to the factory; the customer pays through component cost plus a material margin and minimum order quantities.
How much does a freedom to operate search cost?
Plan USD 10,000 to 30,000 as a starting range. Measured against a production line and a possible injunction, it is the cheapest line item in the project.
What documents and inspections should I plan for before building HNB capacity for the EU market?
Unique identifier marking and movement reporting for traceability, a TPD notification package, formula and process windows from your material suppliers, FTO clearance for both the consumable and the line, and a contract with regulatory events written into the material termination clauses.
How should a full material supply contract handle a flavor ban or an EOL notice?
Name the event class in the termination clauses, check E&O granularity per SKU, and put tooling ownership in writing before production starts.
Next steps. Return to the four-path framing at the top when you compare build, convert, and contract options. Our role in that decision is joint factory establishment and production line supply, or turnkey manufacturing with certification assistance covering TPD and JFRL. If you are at the vendor stage, we will run the checklist from this guide against any factory, including ours.
