Distributors that win long-term in auto parts do not simply buy cheap — they engineer a tiered portfolio: genuine/OEM for critical safety parts, OEM-equivalent for volume SKUs, and quality aftermarket for price-sensitive lines. Each tier has a role.

Defining the three tiers

TierSourceTypical price indexBest applications
OEM / GenuineOriginal equipment supply chain100Safety-critical, warranty, OE-matching needs
OEM EquivalentOE-licensed spec, own brand45–70Volume distribution with brand protection
Aftermarket ProQuality aftermarket manufacturers25–50Price-driven markets, workshops, fleets

Portfolio strategy benchmarks

  • Braking & steering: stay OEM or OEM-equivalent — liability matters
  • Filters, wipers, bulbs: aftermarket pro is fine, high frequency
  • Suspension & cooling: OEM-equivalent is the sweet spot
  • Electronics: verify connectors and software compatibility
  • Aim for 1,000–2,500 fast-moving SKUs before expanding

MOQ and lead-time realities

Fast movers (filters, brake pads) can ship in 5–10 days at MOQs of 100–500 pcs. Engine electronics and OE-sourced turbos take 15–25 days at lower MOQs. Mixed-container programs let you start with 30–50 SKUs instead of committing to full-model ranges.
