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
| Tier | Source | Typical price index | Best applications |
|---|---|---|---|
| OEM / Genuine | Original equipment supply chain | 100 | Safety-critical, warranty, OE-matching needs |
| OEM Equivalent | OE-licensed spec, own brand | 45–70 | Volume distribution with brand protection |
| Aftermarket Pro | Quality aftermarket manufacturers | 25–50 | Price-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.
