CGM OEM vs SKD vs CKD: Choosing the Right Manufacturing Model

Every organisation entering the CGM market faces the same structural question before it faces any product question: how much of the device do we make ourselves? (If the term is new to you, start with what CGM SKD means.)

The answer is not "as much as possible". It is whichever model matches your market's rules, your capital, and your route to patients. There are three standard answers — OEM, SKD and CKD — and the differences are mostly about where the device is finished, and therefore who holds which obligation.

The three models in one table

	OEM / finished goods	SKD (semi-knocked-down)	CKD (completely knocked-down)
What arrives	A finished, certified CGM	Core components, tested and calibrated	Largely unassembled parts
Who finishes it	Manufacturer	Your team, with SOPs and training	Your team, with deeper capability
Typical local investment	Distribution and marketing only	Assembly area, cleanroom, trained staff, registration	Assembly line, process engineering, supplier management
Time to market	Fastest	Fast — sensor development removed from the critical path	Slowest
Duty / local-content treatment	Imported finished device	Commonly qualifies for local-production treatment	Strongest local-content position
Certification holder	Manufacturer's approval, your brand licence	Your local registration, using the manufacturer's technical file	Your registration, with more of the technical file built locally
Branding and lifecycle control	Limited to packaging	Full control of packaging, manual, language, app	Full control, including design changes
Best fit	Fast market entry, low capital	Local-production goals with manageable capability	Long-term manufacturing ambition

OEM: fastest, most expensive per unit

With OEM, you buy a finished device and put your brand on it. Nothing about the device is your responsibility — which is exactly the appeal.

The trade-offs are structural rather than negotiable:

• Landed cost stays high, because you import a finished medical device
• Local-content and tender eligibility is usually unavailable to you
• Your differentiation is packaging, because the product inside is identical to what other partners sell
• The manufacturer owns the roadmap — wear time, warm-up, accuracy improvements arrive on their schedule

OEM is the right answer when speed matters more than unit economics, or when the device is a complement to a business you already run.

SKD: the local-production middle path

SKD is where most organisations with a real commercial channel end up — see how the SKD partnership works end to end. The manufacturer completes the engineering-intensive work — electrode fabrication, membrane coating, calibration, needle loading, tested PCBA — and ships a defined kit. Your team performs final assembly in a controlled environment, applies your branding, and holds the local registration.

What SKD changes:

• Duty and procurement category. Components and locally value-added goods are frequently treated differently from imported finished devices.
• Eligibility. Local assembly plus local registration is often the prerequisite for public tenders and programme supply.
• Capability. You add a cleanroom and trained assembly staff — a bounded, learnable addition rather than an R&D programme.
• Ownership. The brand, the customer relationship and the market data stay with you.

What SKD does not change: the sensor chemistry, the calibration science and the accuracy performance still come from the manufacturer. You are not re-inventing the CGM — you are localising it.

Verid Bio was the first CGM provider to enable SKD/CKD production models overseas, and works with partners on this exact structure.

CKD: the deepest commitment

CKD pushes almost everything to your side. You take on process engineering, incoming quality control, potentially component sourcing, and the full technical file. The upside is maximum local-content position and, at scale, the lowest unit cost. The requirement is genuine manufacturing capability and a multi-year horizon.

Organisations typically arrive at CKD by graduating from SKD — assemble first, learn the process, then take on more of it. Our Leadership Alliance programme is built for that progression.

How to choose: four questions

1. Does your market give material advantage to locally manufactured medical devices? If tenders or duties hinge on origin, OEM disadvantages you structurally.
2. Do you already have a route to patients? Pharmacy networks, hospital procurement, telehealth platforms or distributor reach — SKD compounds an existing channel; it does not create one.
3. What is your tolerance for adding capability? A cleanroom and assembly training are achievable. A full manufacturing organisation is a different decision.
4. How fast must you launch? OEM is fastest. SKD is usually within a similar planning window once enablement is scheduled, because the long-lead engineering is already done.

A practical sequencing note

Many successful programmes do not choose one model permanently. The common pattern is:

OEM or direct distribution to learn the market → SKD to gain local origin and margin → CKD where scale justifies it.

Choosing the model you can execute this year, with a clear option on the next step, beats committing to the model you would ideally hold in five.

Frequently asked questions

Is SKD just OEM with extra steps? No. In OEM the device is finished when it arrives and the manufacturer holds the approval. In SKD the device is finished locally, which changes duty treatment, registration ownership and tender eligibility.

Can SKD work without prior medical device experience? Yes, with the right enablement — assembly SOPs, training, and documentation support. Basic cleanroom protocol knowledge is enough to start.

Which model gives the lowest unit cost at scale? CKD, in theory. In practice SKD often wins on total landed cost once duty and procurement advantages are counted, because it avoids the fixed cost of a full manufacturing organisation.

Who handles regulatory approval in SKD? Your organisation holds the local registration; the manufacturer supplies the technical and clinical documentation package it depends on.
