Sizing the spares package

Spares categories and holding logic
CategoryExamplesHold on site?
Insurance sparesMain gearbox, large motor, control cabinetYes if lead time > 8 weeks and failure stops the plant
Critical wear partsKnives, screens, dies, seals, beltsYes — 6–12 months' consumption
ConsumablesFilters, lubricants, gasketsYes — 3 months
Electronic componentsPLC cards, drives, sensorsSelective — one of each critical type
Structural / rarely failingFrames, tanks, housingsNo
Spares categories and holding logic

As a planning figure, a two-year critical spares package costs 3–6% of equipment value for a standard line and 6–10% where the destination has poor logistics or long customs clearance. That number belongs in the capex request, not in an operating budget discovered in month four.

Negotiate service before award, never after

Service terms to fix during the RFQ

  • Spare parts price list valid for 24–36 months with a capped escalation formula
  • Guaranteed parts availability period — 10 years is a reasonable ask
  • Response time SLA for remote support and for on-site attendance
  • Day rates for service engineers, fixed for the warranty period and beyond
  • Remote diagnostics access and the data the buyer owns
  • Training scope, refresher training and documentation in local language
  • Option pricing for a full-service or preventive maintenance contract
  • Obsolescence notice period for control components

Leverage disappears at contract signature

Spare parts margins are where equipment suppliers earn their real return. Every service term negotiated before award is priced competitively; every one negotiated afterwards is priced as a sole-source.

Maintenance regime that holds availability

  • Criticality analysis: rank every asset by production impact, then match the strategy to the rank
  • Preventive schedules from the OEM manual, adjusted with actual failure data after year one
  • Condition monitoring — vibration, thermography, oil analysis — on rotating critical assets
  • A CMMS holding asset register, schedules, spare parts and work order history
  • Planned shutdown windows scheduled around commercial demand, not around failures
  • Root cause analysis on every stoppage longer than one hour

Questions & answers

Frequently asked questions

How much should we budget annually for maintenance?

Three to six percent of equipment replacement value per year for a conventional processing plant, including labour, parts and contracted services. High-wear industries such as feed milling and recycling sit at the top of that range.

Is a full-service contract worth it?

Usually yes for the first two years in markets without local technical depth, and for complex automation at any time. Beyond that, in-house capability is generally cheaper if the skills can be retained.

What availability should a well-maintained plant achieve?

Ninety-two to ninety-six percent availability is a realistic target for a mature single-line plant with structured preventive maintenance and correct spares holding.

Do you include spares and service in quotation comparisons?

Yes. Two-year spares and five-year service cost are standard lines in our levelled bid comparison, because they often change which supplier is genuinely cheapest.

Industrial financing

Financing routes for operations & roi

Financing is scoped alongside the RFQ, not after supplier selection — the funding route changes the optimal supplier, currency, incoterms and delivery schedule. Global B2B Group never lends, never takes a success fee from buyers and is not tied to any institution. Below are 7 routes buyers commonly compare; amounts, tenors and eligibility are set by each institution.

Export Credit Agencies

State-backed cover (Euler Hermes, SACE, EKF, UKEF, Atradius, K-Sure) on equipment exported from the supplier's country, usually combined with a commercial bank loan.

Best for: Imported production lines and turnkey plants from EU, UK, Korea or Japan

  • Eligible country content
  • Equity contribution
  • Bankable feasibility study
Explore

Development Banks & DFIs

IFC, EBRD, AfDB, ADB, IDB, FMO, Proparco and bilateral development windows funding industrial capex with concessional pricing and long grace periods.

Best for: Food security, cold chain, energy efficiency and job-creating projects in emerging markets

  • ESG / E&S compliance
  • Audited financials
  • Development impact case
Explore

Commercial Lending

Bank term debt and capex facilities secured against project cash flow, equipment and corporate balance sheet, in local or hard currency.

Best for: Established operators expanding proven capacity

  • Debt-service capacity
  • Security package
  • Sponsor equity
Explore

Equipment Leasing

Operating and finance leases that keep machinery off the balance sheet, preserve working capital and align payments with production ramp-up.

Best for: Single machines, packaging lines, handling fleets and phased upgrades

  • Asset resale value
  • Insurance
  • Upfront deposit
Explore

Vendor Financing

Supplier-supported deferred payment and instalment structures negotiated inside the RFQ, before supplier selection narrows your leverage.

Best for: Buyers who want a single contractual counterparty for supply and payment terms

  • Supplier credit appetite
  • Bank guarantee or LC
  • Milestone schedule
Explore

Project Finance

Limited-recourse SPV structures where the facility's own cash flow repays the debt, with independent technical and market due diligence.

Best for: Greenfield plants, integrated processing complexes and utility-scale infrastructure

  • Offtake agreements
  • EPC contract
  • Independent engineer report
Explore

Government Programmes

Industrial localisation incentives, capex grants, interest subsidies, free-zone benefits and agri-processing schemes that reduce effective project cost.

Best for: Projects in priority sectors, special economic zones or import-substitution plans

  • Local registration
  • Job creation targets
  • Application windows

How financing is structured

  1. 1. Scope & budget

    Technical scope and realistic capex band are fixed first — lenders price the project, not the wish list.

  2. 2. Route selection

    We map which of these routes may fit your country, sector, project size and sponsor profile.

  3. 3. Bankable package

    Feasibility, offtake, DSCR model and equipment quotations assembled into a lender-ready file.

  4. 4. Introductions

    Independent introductions to ECAs, DFIs, banks, lessors and equity partners — no exclusivity, no success fee to buyers.
