Plastics & Resins Should-Cost Analysis
A should-cost model for plastics & resins rebuilds the supplier's price from the bottom up — materials, labor, overhead, margin — so you enter every negotiation with a defensible target instead of a "gut feel" discount.
Resin prices track oil and petrochemical feedstocks, but molded parts add tooling, cycle time and cavitation on top. The model exposes exactly where each dollar goes, so you can pressure the right lever instead of asking for a flat percentage off.
Tooling audits, resin-index formulas and DFM reviews commonly deliver 7–15%. SourcingHub's should-cost engine builds this model in minutes, with the plastics & resins-specific drivers pre-loaded.
Fields every Plastics & Resins should-cost analysis should cover
- Resin grade (PE, PP, PET, ABS…) and additives
- Part weight, cycle time and cavitation
- Tooling ownership and amortization
- Regrind / recycled content policy
- Feedstock index (Platts, IHS)
- Colorant and packaging costs

Frequently asked
The essentials for plastics & resins: current price, volume, and the drivers listed above (Resin grade (PE, PP, PET, ABS…) and additives, Part weight, cycle time and cavitation, Tooling ownership and amortization). If you don't have every input, the model uses category benchmarks and flags each assumption.
No — the same logic (cost drivers × utilization × margin) works for services and indirect spend. In plastics & resins, the drivers just shift from raw materials to labor rates, capacity, and pass-through costs.
Within ±5–10% of the supplier's own cost stack is enough to negotiate. The value comes from the conversation the model unlocks, not decimal-precise cost accounting.
Yes. Exports come in a clean executive format (PDF or Excel), and you can share redacted drivers or the full stack depending on your negotiation strategy.
