Portable PEMF Machine for Distributors: Sourcing, Landed Cost and the First Order

Short answer: buying a portable PEMF machine for resale is not a product decision, it is a portfolio decision. You are committing to a set of voltage variants, a documentation package, a spare-parts shelf and a service promise — and the unit price is the smallest part of the risk. Distributors who get this wrong rarely fail on the machine; they fail on a 220V unit landed in a 110V market, a missing test report at customs, or a warranty claim with no spare cable in the country.

This article is written for importers, distributors and clinic-group buyers building a portable PEMF line: how to shape the opening order across the three series, what to confirm before the purchase order, how landed cost actually stacks up, what to keep on the shelf, and how to design the warranty and claims discipline that a reseller is legally exposed to. It stays on the commercial side. If you are buying one machine for your own practice, the clinic operations article in this series covers room setup and payback instead.

What you are actually buying from the factory

A PEMF unit is a power supply, a coil and a control board in a case. The hardware is not where the difficulty sits. What a distributor actually takes on is the following, and each item has to be priced and staffed:

• A voltage commitment. Machines are built for 110V or 220V, and the two are not interchangeable. Buying the wrong variant for a market is not a service issue, it is dead stock.
• A documentation set. Import clearance, marketplace listing and insurance all ask for paperwork that the factory holds and the reseller must be able to produce.
• A parts obligation. The cable and the coil are the wear items. If neither is in your country, every failure becomes a return.
• A claims obligation. Supplier marketing copy is written for consumers. What a reseller may repeat is decided by the reseller's own market, not by the supplier's brochure.
• A service promise. Whoever answers the phone when a unit stops working is you, not the factory. That promise has to be costed before the first sale.

None of that argues against stocking PEMF. It argues for deciding it deliberately, once, instead of discovering it at the first problem.

The three series, and how to shape an opening order

The range is organised in three series — portable, single control and dual control — and within those, six machine configurations. That structure exists because the buyers are different, not because the factory likes options: a home user, a solo therapist, a two-room clinic and a mobile practitioner each need a different case, channel count and control interface. A distributor's job is to cover the buyer types that actually exist in its market, in the ratio they exist.

Series	Who buys it	Role in your catalogue	Commercial risk
Portable	Home users, mobile practitioners, first-time buyers	Volume and entry price point	Price-driven competition; buyers who expect clinic results from an entry unit
Single control	Solo therapists, small clinics, sports clubs	The workhorse that carries margin	Stuck between the entry unit and the dual-channel case on price
Dual control	Busy clinics, two-practitioner rooms, distributors selling on throughput	Premium anchor and demonstration unit	Freight weight, higher capital per unit, longer sell-through

A workable first order in most markets looks like roughly 40% portable, 40% single control, 20% dual control by budget — not by unit count. Dual control units are heavier and more expensive, so 20% of budget is a small number of units; that is correct, because they sell to a smaller group of buyers and they earn their shelf space as demonstration stock rather than as volume. Treat the ratio as a starting hypothesis to be corrected by your first three months of sell-through, not as a rule anyone should defend.

Where the portable series earns its place

The portable series is what makes a PEMF line accessible. It is the unit a physiotherapist buys before they commit to a treatment room, and the unit that a home buyer can justify without a business case. Because it is the entry point, it is also where a catalogue gets its first review, and reviews are what a new distributor needs more than margin.

Voltage, plug and market fit

Voltage is the first thing to lock, and it is the cheapest thing to get wrong at the factory and the most expensive to fix after landing. The range is built in 110V and 220V variants, and a 110V unit does not become a 220V unit with an adapter. Decide three things before the purchase order leaves your desk:

• Nominal voltage and frequency for every destination market. If you sell into both 110V and 220V markets, split the order at the factory. Do not plan to convert locally.
• Plug type per market. A plug adapter is a retail accessory, not a compliance solution. The unit should arrive with the plug the market expects, and the label should match.
• Which SKUs are single-voltage only. Assume every model is, until the factory confirms a switchable version in writing for that specific model. "It usually works" is not a specification.

Write the voltage and plug into the purchase order itself, per line item, and check the label artwork against it. Most voltage mistakes are not manufacturing errors; they are an order that never specified the variant and a factory that shipped its default.

Documentation to request before the first purchase order

This is the part distributors most often skip, and it is the part that costs the most time later. Ask for the set below in writing, per model, and keep it in a folder you can send to a broker, a marketplace or an insurer without going back to the supplier. Whether a given document is required depends on your market and your channel, so confirm the exact list with your customs broker and, where relevant, your regulator before you order.

• Electrical safety and EMC test reports covering the specific model and voltage variant — not a report for a different model in the same family.
• Declaration of conformity or equivalent supplier declaration, naming the model, the standards applied and the issuing body.
• Label and marking artwork, so the rating plate, warnings and language can be checked before shipment rather than after.
• Declared net and gross weight, plus carton dimensions per unit — this is what freight is actually priced on.
• HS code the factory uses when exporting, so your broker can confirm the classification in your own market rather than inheriting one.
• Spare-part price list and lead times for the coil, the applicator cable and the power lead.
• Warranty statement in writing, with the covered period, what is excluded and who pays freight in each direction.
• Serial or batch numbering convention, so a returned unit can be traced to a production run.

If a supplier cannot produce one of these for a specific model, that is information too — it tells you which SKU to leave out of the first order rather than which argument to have later.

Landed cost: how the number actually stacks

Distributors usually compare supplier quotes and then discover the real cost after the first shipment. The stack below is deliberately generic, because the rates differ by market, by Incoterm and by whether you are VAT-registered. Substitute your own figures; the structure is the part worth keeping.

Cost line	Basis	Illustrative rate	On a goods value of 100
Goods	Supplier invoice, ex works	100	100.00
Freight and insurance	Per kilogram and cubic metre, not per unit price	8%	108.00
Duty	Applied to the customs value your broker declares	6%	114.48
Clearance, handling, last mile	Per shipment plus per unit delivery	3 points	117.48
Landed, before tax	What the unit has cost you in the warehouse	1.17x goods	117.48

Two mechanics decide whether that number is close to reality. First, duty is usually applied to a value that includes freight, so the order of the percentages matters — duty on goods alone understates the stack. Second, VAT or sales tax is not a cost if you are registered and can recover it; it is cash flow. Distributors who fold recoverable tax into landed cost then price themselves out of the market, and distributors who ignore it entirely run out of working capital on the first reorder.

Set your retail price from the landed figure, not the supplier invoice. If a unit lands at 117.48 and retails at 199, gross margin before your own costs is 41%. That 41% has to absorb the demonstration unit you keep, the spare parts shelf, warranty freight, marketplace fees and the sales time spent on a considered purchase. It is workable. It is not generous, and pricing at 149 on the same landed cost leaves 21%, which is not a distribution business.

What to keep on the shelf

The wear parts are known, and they are few: the applicator cable and the coil are what fail, in that order. Everything else in the case is a sealed unit that either works or is a warranty event. That makes the spare-parts decision simple, and it should be made with the opening order rather than after the first claim.

The three case classes behave differently in freight and in service, and a distributor needs to know which class each SKU sits in before quoting:

• Compact carry case. The portable class, around 34 × 27 × 16 cm and roughly 5 kg of machine. Cheapest to freight, easiest to stock deep, and the format most exposed to price competition.
• Wheeled case. The single and dual control class, around 35 × 27 × 65 cm and in the region of 20 kg. Volumetric weight, not actual weight, is what you will be charged on, so quote freight on the carton dimensions rather than the scale.
• Console. A vertical wheeled unit that is not a portable product at all. It ships and installs differently, it sells to clinics rather than to individuals, and it belongs in the catalogue only if you can support it.

As a starting policy: one spare applicator cable and one spare power lead per five units sold, and one spare loop per ten if you sell loops separately. Branded units should have their spares ordered in the same production run — a branded machine with an unbranded replacement cable reads to the customer as a repair, while a matched spare reads as a system.

The dual-control case: a premium SKU with a different buyer

Dual control is usually presented as a specification upgrade. Commercially it is a different sale. The buyer is not comparing features on a page; they are working out whether a second channel removes a bottleneck in a booked diary. That buyer is fewer in number, slower to decide and much less price-sensitive — which is exactly why a dual-control unit belongs in a distributor's range as an anchor rather than as a volume line.

Where the dual-control case earns its price

Two applicators running at the same time lets a practitioner treat two areas of one client in a single window, or two clients at once where the room, the supervision and the local rules allow it. For a reseller, that is the demonstration that closes the sale: put the dual-channel unit next to the single-channel one and let the buyer watch two coils work at once. It is the only specification in the range that a buyer can understand in five seconds.

Two commercial cautions. A dual-channel unit carries more capital per unit and more freight weight, so it ties up working capital for longer than the portable line. And the second channel only justifies its price in a market where practitioners are actually turning work away — in a thin market, it sits in the warehouse and the discount you eventually give to move it comes straight out of the margin you planned.

One anchor SKU that is not portable

Most distributors eventually need a unit that is not portable: something a clinic group can install, that looks like capital equipment, and that gives the range a top end. Without it, every conversation is about price, because every product you offer fits in a car boot.

For clinic groups and rehabilitation buyers

A vertical console changes the sale from "a device" to "equipment in a room". It is also a different service obligation — installation, a larger footprint and a buyer who expects an on-site answer — so it belongs in the catalogue only if you can support that promise in your own market.

Private label: what is actually configurable

Branding is the easiest part of a distributor conversation and the easiest part to over-promise. What is configurable on this range is specific and physical: a logo on the case, a logo on the screen, the interface language, the handle colour and the case colour, and on some formats a logo on the loop itself. What that means commercially is that private label changes what the customer sees, not what the machine does — so it does not create a differentiated product, it creates a differentiated shelf presence.

• Decide the brand question before the first order, not after. Re-branding an existing stock unit is not a factory process; branding happens in the production run.
• Check the interface language against your market. An English-only panel in a market that expects a local language is a support cost, not a cosmetic one.
• Order spares inside the same run. A branded machine with an unbranded spare cable undermines the branding at exactly the moment the customer is already unhappy.
• Keep the neutral option available. Some buyers — clinic groups with their own identity, or resellers testing the category — are better served by an unbranded unit with a fast reorder than by a brand investment.

Claims discipline: what you may not repeat

Supplier marketing is written to sell a unit to an individual. Reseller copy is governed by the reseller's market, and the gap between the two is where distributors get into trouble. Consumer creative for this category commonly carries statements about relaxation, sleep, recovery, performance and pain; whether you may repeat any of them depends on your jurisdiction, your channel's policy and whether you can substantiate the claim. Assume you cannot, unless you have checked.

The image above is a good example of the problem in a harmless form: it is excellent at communicating what the product is and how it is used, and it also carries wellness claims written for a consumer audience. Use the product truth — the format, the applicator, the weight, the use case — and write your own claim set, or none. A practical working rule for a new distributor:

• Describe the device, not the outcome. Format, applicator, settings, session length, weight and case class are factual and defensible.
• Do not inherit superlatives. Unqualified comparative and superiority claims travel badly across borders and are the first thing a competitor or a regulator picks up.
• Keep a substantiation file per claim. If a statement appears on your listing, you should be able to produce the source within a day.
• Give practitioners a written intake checklist. Screening for implants, electronic medical devices and pregnancy, with a rule to stop and refer, is standard practice and it protects the reseller as much as the user.

Warranty and returns: design the promise before the sale

The factory's warranty covers the factory. Your customer's warranty is yours, and the distance between the two is a cost you have to fund. Before the first sale, agree in writing — with the supplier and inside your own business — four things:

• The dead-on-arrival window. How long after delivery a unit is replaced rather than repaired, and who decides. A short, clearly stated window is better than a long, vague one.
• Who pays freight each way. This single line decides whether a warranty claim costs you a cable or a machine. Cross-border return freight on a 20 kg wheeled case is not a rounding error.
• Swap versus repair. If you hold one spare unit per ten sold, you can swap first and diagnose later. If you hold none, every failure is a customer waiting.
• What voids cover. Voltage mismatch, water, and third-party repair are the usual exclusions. State them at the point of sale so they are not a surprise at the point of claim.

Two operational habits make this manageable. Register the serial number at the point of sale, so a claim can be tied to a batch without an argument. And keep the failure reasons in one place from the first month: after twenty claims you will know whether your problem is the cable, the coil, or the way customers are using the unit — and only one of those is a supplier conversation.

First 90 days after the container lands

1. Inspect and stage one unit per SKU. Power it up, run a session on yourself, photograph the label. Voltage and plug errors are cheapest to catch in week one.
2. Build the demonstration pair. One single-channel and one dual-channel unit, permanently set up. This is the highest-return capital in the whole order.
3. Put the documentation folder online. Test reports, declarations, label artwork and spare-part prices, in one place your sales team can reach.
4. Train on the two failure modes. Cable handling and coil storage. Most early claims are usage, not defect, and a five-minute briefing removes a large share of them.
5. Price from landed cost, then check the market. If the resulting price is not competitive, revisit the SKU mix rather than the margin.
6. Review the ratio at day 90. Which series actually moved, which did not, and what that says about the buyers in your market. Correct the second order with evidence, not with the original plan.

Frequently asked questions

What is a sensible opening order for a portable PEMF line?

Enough to cover three buyer types and produce a demonstration pair, and no more. In most markets that is a split of roughly 40% portable, 40% single control and 20% dual control by budget, with at least one dual-channel unit kept set up for demonstration. The right number of units depends on how many resellers or clinics you can reach in the first quarter, not on a container minimum.

Are the 110V and 220V versions interchangeable?

No. The range is built in both variants and a 110V unit does not become a 220V unit with a plug adapter. Specify voltage and plug type per line item on the purchase order, split the order at the factory if you sell into both kinds of market, and check the label artwork against the order before shipment.

Who is responsible for import clearance and duty?

It depends on the Incoterm you agree, and it should be explicit in the contract rather than assumed. As the importer of record, the reseller normally carries clearance, duty and compliance obligations in its own market. Confirm the classification, the customs value basis and the documentation list with a local broker before the first shipment.

What documents should I ask for before the first purchase order?

Electrical safety and EMC test reports for the exact model and voltage variant, a declaration of conformity or equivalent supplier declaration, label and marking artwork, declared net and gross weight with carton dimensions, the export HS code, a spare-part price list with lead times, a written warranty statement, and the serial or batch numbering convention.

Can the machine carry my own brand?

Yes, within the limits of what is physically configurable: case logo, screen logo, interface language, handle colour, case colour and, on some formats, a logo on the loop itself. Branding is applied during the production run, so the decision has to be made before the order rather than after the stock arrives.

What spare parts should a distributor stock?

The two wear items: applicator cables and power leads, plus coils if you sell loops separately. A workable starting policy is one spare cable and one spare power lead per five units sold, and one spare loop per ten. Keeping one complete spare machine per ten units sold lets you swap on a warranty claim instead of making the customer wait for diagnosis.

How should a reseller handle a unit that fails in the first month?

With a written policy agreed before the sale: a defined dead-on-arrival window, a swap-first process if you hold spare stock, and clarity on who pays freight each way. Register the serial number at the point of sale so the unit can be traced to a production batch, and log every failure reason — the pattern after twenty claims tells you whether the issue is the product, the accessory or the usage.

How is a portable PEMF line priced for resale?

From landed cost, not from the supplier invoice. Build the stack of goods, freight and insurance, duty, and clearance or last-mile costs, keep recoverable tax out of the cost base, and then set retail against that figure. A unit that lands at about 1.17 times goods value and retails at roughly 1.7 times landed cost is workable; the margin then has to absorb demonstration stock, spares, warranty freight and sales time.

Honkay manufactures PEMF therapy equipment in China, including a portable range built for home users, therapists, clinics and distributors. Units are available in 110V and 220V variants, and OEM, ODM and private-label options are supported across the range.
