INSURANCE FOR OEMs, EMS & CONTRACT ELECTRONICS MANUFACTURERS
Why Contract Electronics Manufacturing Needs Specialist Insurance
OEM and contract electronics manufacturing (EMS) businesses often carry high values of components and work in progress — much of it customer-owned — while operating under strict delivery schedules and demanding quality standards. A single incident can create cascading impacts: scrapped boards, delayed shipments, expedited logistics, and downstream claims if defective products reach end users.
EMS operations also sit at the centre of supply chains. Shortages, supplier failures and logistics disruption can halt production. In parallel, many EMS businesses have significant ESD exposure and rely on process controls (reflow profiles, calibration, traceability) to prevent quality escapes. This creates a mix of property, financial and liability risk that generic manufacturing insurance often does not address well.
Insure24 arranges specialist insurance for OEMs, contract electronics manufacturers, PCBA assembly operations, box-build and integration businesses, and outsourced test and repair operations. We help you structure cover for property, customer stock, machinery breakdown, business interruption, public and product liability, and cyber — and we help you reduce uninsured contract exposures by aligning insurance with your customer agreements.

Who This Insurance Is For (OEM, EMS & Contract Manufacturing)
“Contract electronics manufacturing” covers a wide spectrum: from prototype and low-volume specialist builds through to high-volume PCBA and full box-build operations with test, programming, conformal coating and repair. Insurance needs differ depending on whether you own designs, manufacture under customer BOMs, store customer components, or provide warranty and repair services.
Underwriters typically want to understand your role in the value chain: are you designing, building to print, sourcing components, performing test and programming, or providing after-sales support? The more responsibility you assume (design, specification, supply chain, warranty), the more carefully liability and contract risk needs to be managed.

- Security systems and access control products
Core Cover 1: Property, Contents, Stock & Customer-Owned Goods
EMS sites often hold significant values of components, boards and finished goods — and in many cases, the most valuable items are not owned by the EMS business. That makes “goods in custody” (bailment) one of the most important topics to get right. If a fire, flood or theft occurs, you need clarity on whether the policy responds to customer-owned goods and how valuation is treated.
Another critical issue is WIP valuation. Work in progress may include customer-supplied components, partially assembled boards, and completed boards awaiting test. If policies use the wrong valuation method or limits are based on average values rather than peak exposure, insurers can reduce claims.
Insure24 helps structure property cover that reflects peak stock and WIP, includes customer goods where agreed, and avoids common wording gaps around ESD-sensitive components and high-value inventory.
Property / Stock Cover Can Include
- Buildings and tenants’ improvements (where applicable)
- Contents, plant, tools and office/workshop equipment
- Stock: components, PCBs, finished goods
- Work in progress (WIP) at defined valuation basis
- Customer-owned goods in your custody (where agreed)
- Goods in transit options (often arranged separately)
- Debris removal and professional fees (where included)
- Optional: accidental damage extensions (market dependent)
EMS-Specific Points to Get Right
- Customer custody (bailment) language and maximum values on site
- Peak stock/WIP exposure (not only monthly averages)
- Valuation: replacement cost vs manufacturing cost vs contract value
- ESD controls and how insurers view ESD-related loss scenarios
- Storage protection, security, access control and CCTV evidence
- Fire protection and compartmentation (severity driver for stock losses)
- Wording clarity: “electrical/electronic breakdown” vs insured perils
- Deductibles that remain workable for batch/stock claims
Core Cover 2: Machinery Breakdown & Business Interruption (BI)
Many EMS businesses assume that the biggest risk is “stock loss”. In reality, downtime can be just as damaging — missed delivery schedules, expedited shipping, overtime, subcontracting and strained customer relationships. Machinery breakdown cover (engineering) can protect against sudden internal failure of equipment such as reflow ovens, pick-and-place machines, compressors, chillers, conveyors and test rigs.
Business interruption cover protects your gross profit (or contribution) when insured events disrupt operations. The key is aligning triggers: property damage, breakdown events and (where appropriate) cyber incidents. If your BI is only triggered by property damage, a major breakdown loss could be uninsured beyond the repair invoice.
Insure24 helps you build a coherent programme: property + breakdown + BI + extra expense — so you can recover faster and protect cashflow when incidents occur.
What Breakdown / BI Can Cover
- Repair/replacement following insured equipment breakdown
- Optional: breakdown-triggered BI and extra expense (where arranged)
- Business interruption after insured property damage
- Increased cost of working: overtime, subcontracting, emergency logistics
- Expediting expenses to reduce downtime (policy dependent)
- Claims preparation costs (where included)
- Temporary plant hire / alternative premises options (where feasible)
- Optional: supplier dependency (contingent BI) extensions
BI Factors Insurers Price Heavily
- Single points of failure: one oven/one line/one test bottleneck
- Spare parts strategy and realistic repair lead times
- Maintenance programmes and evidence of condition monitoring
- Ability to shift production to other lines/sites/subcontractors
- Order concentration: reliance on one key OEM contract
- Indemnity period and recovery timeline credibility
- Deductible/waiting period alignment with realistic downtime events
- Supply chain and component availability constraints
Core Cover 3: Public, Employers’ & Product Liability (and Recall Exposure)
Contract electronics manufacturers need robust liability cover because products are embedded into downstream systems. Even if a fault originates upstream (a component issue), your business may still be pulled into disputes about assembly processes, workmanship, testing or traceability.
Public liability covers third-party injury or property damage arising from your premises/operations. Employers’ liability is legally required for most UK businesses with employees. Product liability covers claims alleging injury or property damage caused by defective products. Some businesses also consider product recall/withdrawal expenses, which is often separate from product liability.
We also help clients understand the boundary between insured liability and uninsured commercial remedies such as chargebacks, contractual penalties, and “cost of rework” demanded under contract. These are often not insurable in the way customers assume, so contract alignment is crucial.
Liability Covers Often Needed
- Employers’ liability (UK legal requirement for most employers)
- Public liability (visitors, contractors, third-party property damage)
- Product liability (injury/property damage from products supplied)
- Worldwide territories (including USA/Canada where needed)
- Legal defence costs included within policy cover
- Optional: vendors/additional insured endorsements (market dependent)
- Optional: recall/withdrawal expense cover (separate cover)
- Support with certificates for OEM procurement onboarding
Underwriting Focus Areas for EMS Liability
- End markets (automotive, medical, aerospace, industrial, consumer)
- Territories/export footprint (direct and indirect)
- Traceability, lot control, quarantine and rework governance
- Test coverage: functional test, AOI/X-ray, programming and burn-in
- Process control: reflow profiles, calibration, ESD and handling
- RMA/field failure history and evidence of corrective actions
- Contractual requirements and assumed liabilities
- Quality certifications and audit results (where applicable)
Cyber, Data & Supply Chain Risk for Contract Manufacturers
EMS businesses commonly handle sensitive design files, customer BOMs, firmware images, programming data and test records. Many also provide remote support, connect to customer portals, and rely on third-party logistics and component distributors. That creates cyber and supply chain exposure: ransomware can halt production, a compromised email account can trigger invoice fraud, and supplier failure can stop builds entirely.
Cyber insurance can cover incident response, forensic investigation, legal/regulatory costs and data restoration. Depending on wording, it can also provide cyber-triggered business interruption. For EMS operations, it’s important to align cyber with operational reality: backups, access controls, segregation, and third-party access governance.
Where supply chain dependency is extreme, contingent BI extensions or bespoke solutions may be considered to address key supplier failure — though availability and wording vary across the market.
Cyber Covers Often Considered
- Incident response, forensics and specialist support
- Data restoration and system recovery costs
- Cyber business interruption / network interruption (where included)
- Ransomware response support (policy dependent)
- Third-party liability for breaches (where relevant)
- Regulatory defence and notification costs
- Business email compromise and invoice fraud add-ons (market dependent)
- Supply chain incident response considerations (wording dependent)

Compliance, Quality Systems & Evidence (Why It Improves Terms)
EMS businesses often win better insurance terms by evidencing disciplined quality governance: traceability, test coverage, calibration, ESD controls, and documented corrective actions. These controls reduce the probability of a wide recall and help limit claim severity by identifying impacted lots quickly.
We help you package this evidence for insurers and align it with customer procurement requirements — so that you can pass onboarding and renewals without scrambling for documents.
- Traceability, lot control and quarantine procedures
- AOI/X-ray/functional test coverage and documentation
- Calibration records for critical tools and measurement equipment
- ESD controls, audits and training records

FREQUENTLY ASKED QUESTIONS
+-
What insurance does a contract electronics manufacturer (EMS) need?
Most EMS businesses consider property/contents, stock & WIP (including customer-owned goods in custody where agreed), machinery breakdown, business interruption and extra expense, employers’ liability, public liability and product liability. Many also add cyber cover, goods in transit, and optional recall/withdrawal expense cover.
+-
Can insurance cover customer-owned components stored at our site?
Often yes, but it must be specifically structured. Insurers need clarity on custody terms (bailment), maximum values, valuation basis and security/fire protection. We can help ensure customer-owned goods are included properly and that limits reflect peak exposure.
+-
Does product liability cover rework costs and chargebacks?
Usually not. Product liability is typically designed for third-party injury or property damage (plus defence costs). Many contractual remedies—chargebacks, penalties, cost of rework and purely commercial losses—may be excluded. Contract alignment and optional recall/withdrawal expense cover can help where appropriate.
+-
Why is machinery breakdown cover important for SMT and test lines?
Many severe disruptions come from internal equipment failure rather than fire/flood. Breakdown cover can pay for repair/replacement of key equipment and, when arranged with breakdown BI/extra expense, can protect cashflow from downtime and emergency costs.
+-
What information do insurers need to quote OEM/contract electronics manufacturing insurance?
Insurers typically want: turnover and activities (PCBA/box build/test/repair), end markets and territories, values (property, stock, WIP and customer goods), fire and security protection, equipment schedule and maintenance strategy, BI requirements/indemnity period, quality governance (traceability, test coverage, calibration, ESD), and loss/RMA history with corrective actions.
+-
Can cyber insurance help with ransomware and production disruption?
Often yes, depending on policy wording. Cyber insurance can cover incident response, forensics, system restoration and sometimes cyber-triggered business interruption. Good backups, MFA and access control evidence can also improve underwriting terms.
