Resin Cost Savings in PE Portfolio Companies: A ResinSmart Guide

Your portfolio company just closed. The dust is settling. And buried in the procurement spend is a line item that could make or break your investment thesis: resin.

Most private equity (PE) firms treat resin like any other procurement category. Yet it often represents the single largest controllable cost in manufacturing—up to 75% of part cost in plastics-intensive operations. That gap between its impact and the attention it receives makes resin one of the fastest value creation levers you can pull post-close.

Unfortunately, traditional procurement methods usually miss this opportunity entirely.

Generic playbooks and spend analytics platforms don’t have the specialized market knowledge to tackle resin's extreme technicalities and opaque pricing. They treat it like any other cost when, in reality, it’s anything but ordinary. And that’s putting it mildly.

But we’re changing all of that with this guide. Drawing on decades of frontline resin procurement experience, we've built something PE firms have been missing: a practical, step-by-step roadmap designed specifically for portfolio company value creation. Not theory. Not generic best practices. Instead, a proven process you can start implementing today, from quick wins in the first 90 days to structural improvements that compound value through your hold period.

The firms that get resin right don't just save money. They transform a volatile cost center into a predictable competitive advantage. And in a market where operational improvements separate winners from also-rans, that advantage compounds fast. So let’s get to it.

The Resin Procurement Opportunity

The global resin market is massive—$925.8 billion in 2025, projected to hit $1.3 trillion by 2033. For PE firms with manufacturing portfolios, that scale means resin touches nearly every investment, driving costs that directly impact returns.

Thus, resin procurement has moved from the back office to the boardroom. When a single category can represent your largest controllable cost, when price swings can erase quarters of operational improvements overnight, procurement becomes strategy, as critical to post-close success as any revenue initiative.

Yet most portfolio companies are playing defense, not offense.

Walk into any newly acquired manufacturer and you'll typically discover the same procurement challenges:

• Over-specified grades that cost 30% more than functional equivalents
• No systematic price benchmarking against market indices
• Single-source dependencies that destroy negotiating leverage
• Grade proliferation where five different resins do the job of one
• Contracts tied to inflated benchmarks with hidden escalators
• Payment terms that favor suppliers, not buyers

But these aren't just inefficiencies. They're opportunities. Again, while resin looks like any other raw material on a P&L, it behaves nothing like traditional procurement categories:

• Extreme volatility. Feedstock swings, tariffs, and supply shocks create price chaos that would be crisis events in other categories.
• Technical barriers. Suppliers exploit buyers' limited understanding of grade specifications and chemistry to maintain premium pricing.
• Opaque pricing. Unlike transparent commodities, resin hides behind supplier-friendly indices and selective price sharing.
• Supplier concentration. A handful of producers control the market, maintaining discipline that limits buyer options.

And that’s just for starters. As a result, these dynamics trap manufacturers in a costly cycle, absorbing volatility they can't predict, paying premiums they can't identify, and locked into contracts they can't optimize. In the bigger picture, the resulting margin pressure isn't so much from rising costs as it is from underlying procurement strategies that haven't evolved to match market realities.

Still, there’s very good news buried within this mountain of negativity:

Procurement offers something unique for PE value creation where, unlike revenue growth or market expansion, procurement improvements are entirely within your control.

You don't need customer approval. You don't need market conditions to align. You just need the right approach, the right data, and the commitment to treat procurement as the strategic function it's become.

The opportunity is massive and entirely capturable. The question is how to systematically extract it.

Step-by-Step Procurement Roadmap

Systematic extraction requires more than good intentions and a few supplier meetings. It requires a proven process that transforms procurement from a scramble into a science.

The roadmap that follows isn't theoretical. It's been refined across dozens of portfolio companies, each phase building on the last to create capabilities that compound over time. Quick wins in the first 90 days fund deeper initiatives. Early data collection enables smarter negotiations. Small pilots prove what's possible before you bet big.

Most importantly, this approach recognizes that lasting change happens in stages. You can't revolutionize procurement overnight, nor should you try. Instead, you build momentum methodically, from assessment through implementation to optimization, turning resin procurement from a cost center into a competitive advantage that strengthens throughout your hold period.

Phase 1: Assessment & Planning (0-90 Days)

Goal: Build visibility into resin spend and secure quick wins.

The first 90 days set the tone for everything that follows. You need that momentum we mentioned, but you also need understanding. Push too hard without grasping the technical requirements and you'll make costly mistakes. Move too cautiously and you'll miss the post-acquisition window when change is expected.

Key Actions

Start with the fundamentals: you can't optimize what you can't see. Most portfolio companies have resin data scattered across multiple systems, facilities, and business units. Your first priority is consolidating this chaos into clarity.

Build complete spend visibility:

• Consolidate resin spend data across all facilities and business units
• Create a spend cube showing consumption by grade, supplier, and location
• Map actual consumption against contracted volumes
• Identify off-contract "maverick" spending

Benchmark against market reality:

• Pull ICIS, CDI, or Platts indices for every grade you buy
• Calculate the delta between your prices and benchmarks
• Flag any supplier consistently pricing above market
• Identify contracts tied to outdated or unfavorable indices

Hunt for rationalization opportunities:

• Catalog every grade across the organization
• Identify functional overlaps (different grades, same application)
• Calculate potential savings — consolidation can often eliminate a significant share of redundant grades (sometimes 20% or more) without sacrificing performance
• Build a priority list based on ease and impact

Secure early wins:

• Renegotiate contracts expiring within 90 days
• Re-bid categories where you're paying 15%+ above market
• Improve payment terms (moving from net 30 to net 60 can unlock meaningful working capital savings, often worth several percentage points of annual resin spend)
• Consolidate fragmented orders to hit volume breaks

Questions to Answer as You Go

• Do we know our true resin spend by grade, supplier, and facility? Without this baseline, you're flying blind. Most companies underestimate spend by 10-15%.
• How do current prices compare to benchmark indices? Portfolio companies frequently discover they’re paying 20% or more above market benchmarks without realizing it. On a $10M resin budget, that can mean millions in hidden margin leakage.
• Where are we paying premiums for redundant grades? Every additional grade means less leverage and higher prices.
• What contracts or terms can be renegotiated in the next 60 days? Contracts about to renew give you immediate leverage without penalties.

Common Pitfalls to Avoid

• Moving without operations buy-in. The plant manager who's run the same resin for 10 years won't embrace change unless involved early.
• Focusing only on unit price. For example, chasing a small discount on resin that increases scrap rates can wipe out savings entirely and create hidden costs downstream.
• Alienating teams with data requests. Start with available data. Build better systems after you've proven value.

Remember, Phase 1 isn't transformational. It's foundational. The data you gather, the relationships you build, and the credibility you earn in these first 90 days determine whether procurement becomes a sustainable competitive advantage or another abandoned initiative.

Most importantly, the quick wins aren't just for show. They fund what comes next. That 5% you save through payment term improvements? That's the budget for the procurement talent you'll need in Phase 2. The trust you build with operations by involving them early? That's the political capital you'll spend when pushing bigger changes. Everything compounds.

Phase 2: Strategic Implementation (3-12 Months)

Goal: Lock in structural savings and build resilience.

Phase 1 gave you visibility and quick wins. Now it's time for the moves that fundamentally reshape your resin economics. This is where procurement shifts from tactical cost-cutting to strategic value creation. In other words, the difference between saving 5% and saving 15%.

Key Actions

The structural changes you make now will define your resin costs for years. Move deliberately but decisively. Every month you delay is margin left on the table.

Rationalize your supplier base strategically:

• Consolidating 70–80% of spend with 2–3 suppliers can yield double-digit cost improvements through better leverage.
• Maintain qualified alternates for every critical grade
• Phase transitions over 60-90 days to prevent disruptions
• Keep safety stock at 1.5x normal levels during switches

Launch portfolio-wide RFPs:

• Aggregating demand across the portfolio can deliver significantly better pricing as high-volume buyers routinely outperform individual sites.
• Bundle similar grades to maximize volume leverage
• Include both incumbents and challengers to create competition
• Structure contracts with built-in performance metrics

Shift to market-aligned pricing:

• Transition from fixed to index-based pricing where volatility is high
• Negotiate "index-minus" contracts when you have leverage
• Build in caps and collars to limit extreme swings
• Ensure you understand the index methodology (not all indices are created equal)

Pilot alternative materials:

• Test recycled content at 25%+ blends in non-critical applications first
• Explore grade substitutions (Nylon to PP can deliver 37% savings)
• Run parallel trials to validate performance before full conversion
• Calculate total cost impact including processing changes

Deploy real procurement technology:

• Implement spend analytics platforms for portfolio-wide visibility
• Set up automated price benchmarking against indices
• Create dashboards that procurement and finance both understand
• Build early-warning systems for price movements

Questions to Answer as You Go

• Can portfolio demand be aggregated for stronger leverage? When five separate portcos under one PE group buy 5 million pounds each, they have very different leverage than one entity buying 25 million pounds. But aggregation only works with coordination.
• Are we over-reliant on any single supplier? If one supplier has more than 40% of your spend, you're vulnerable. If they have 80%, you're hostage.
• Which contracts should shift to index-based pricing? Fixed pricing feels safe until markets drop and you're locked in above market. Index-based works when you understand the volatility.
• Where can recycled or alternate resins be piloted safely? Start with hidden applications—internal components, non-visible parts. Build confidence before touching customer-facing products.
• Do we have the tech stack to track resin spend portfolio-wide? Excel doesn't scale. You need real systems to maintain visibility as complexity grows.

Common Pitfalls to Avoid

• Supply disruptions during consolidation. Never eliminate a supplier before their replacement is qualified and performing. Maintain dual supply for 60 days minimum. Keep safety stock at 1.5x normal. Phase transitions, don't flip switches.
• Sacrificing operations for savings. That 10% savings means nothing if production lines stop. Involve operations in every supplier change. Run pilots before commitments. Document quality requirements religiously.
• Over-consolidating suppliers. Two suppliers competing keeps prices honest. One supplier becomes complacent. Zero alternatives means you're trapped when issues arise.
• Ignoring hidden switching costs. New resins might require different processing temperatures, longer cycle times, or modified tooling. A 5% material savings can disappear into 10% higher processing costs if you don't account for the total system impact.

Phase 2 is where good intentions become lasting change. The suppliers you qualify, the contracts you structure, and the systems you build create a procurement foundation that generates value long after the consultants leave.

More importantly, this phase proves the model at scale. When the board sees 10-15% sustainable cost reduction across the portfolio—not just one-time wins but structural improvements—procurement graduates from cost center to value driver. That shift in perception unlocks resources and support for the continuous optimization that defines true procurement excellence.

Phase 3: Continuous Optimization (12+ Months)

Goal: Institutionalize best practices and evolve into advanced strategies.

You've captured the low-hanging fruit. You've restructured contracts and rationalized suppliers. Now comes the harder work: making excellence systematic. Phase 3 transforms procurement from a project into a capability, one that builds value through your entire hold period and drives exit multiples.

Key Actions

Now you institutionalize what works, building processes that keep delivering savings long after the initial push.

Establish governance that sticks:

• Create quarterly procurement reviews with standardized KPIs
• Build dashboards that connect procurement metrics to EBITDA impact. For example, on a $50M resin spend base, a 1% cost reduction adds $500K to EBITDA, and the same logic scales up or down depending on portfolio size.
• Set up monthly supplier scorecards tracking price, quality, and delivery
• Implement variance reporting that catches slippage before it compounds

Foster cross-portfolio collaboration:

• Launch quarterly forums where procurement teams share wins and warnings
• Create a shared database of qualified alternative suppliers
• Standardize contract templates and negotiation playbooks
• Build peer benchmarking to identify outliers. So, if one portco is paying 12% above benchmark for PP while another is at market, the gap becomes an immediate savings opportunity

Deploy sophisticated risk management:

• Explore financial hedging for high-volatility grades. For instance, hedging PE or PP when 3–6 month forward curves signal risk. Even partial hedges can stabilize millions in resin spend.
• Structure contracts with automatic price adjustments based on feedstock movements
• Build scenario models for major supply disruptions
• Develop dual-sourcing strategies for critical materials

Embed sustainability metrics:

• Track percentage of recycled content by product line
• Set targets for post-consumer resin adoption. Many consumer brands now mandate 25–50% recycled content in packaging by 2030. Getting ahead of these targets prevents last-minute, premium-cost sourcing.
• Build supplier scorecards that include ESG performance
• Prepare for inevitable customer requirements around circular economy

Leverage emerging technology:

• Implement AI-driven demand forecasting to optimize inventory
• Deploy predictive analytics for price movement alerts
• Use real-time data and predictive analytics to flag price movements. Apply machine learning to identify grade substitution opportunities. For example, surfacing when a lower-cost PP grade could replace a specialty resin without performance loss.
• Automate routine procurement tasks to focus talent on strategic initiatives

Questions to Answer as You Go

• Are resin procurement KPIs tracked at the board level? If procurement metrics aren't in the board deck, they're not really priorities. Visibility drives accountability.
• How are we sharing wins across portfolio companies? One company's breakthrough is everyone's opportunity. But without formal mechanisms, lessons stay siloed.
• Where would financial hedging reduce volatility risk? Not every grade needs hedging. Focus on high-volume, high-volatility categories where swings materially impact margins.
• What ESG commitments should shape procurement strategies? Your customers' sustainability goals will become your procurement mandates. Better to lead than scramble.
• Which new technologies can give us forward-looking visibility? The winners in resin procurement won't be those with the most data. Instead, it’ll be those who turn data into decisions fastest.

Common Pitfalls to Avoid

• Declaring victory too early. Markets change. Suppliers adjust. Yesterday's savings can quickly disappear without continuous pressure and monitoring.
• Underinvesting in talent. Procurement excellence requires expertise. The savings from one avoided mistake pays for years of skilled talent.
• Ignoring market evolution. New grades, new suppliers, new technologies constantly emerge. Standing still means falling behind.
• Treating sustainability as optional. ESG requirements are moving from nice-to-have to table stakes. Ignore them now and you’ll pay the consequences later.

Phase 3 separates firms that achieve temporary cost reduction from those that build a lasting edge. The systems you implement, the capabilities you develop, and the culture you create determine whether procurement remains a value driver through exit.

Most importantly, these capabilities become a selling point themselves. When potential buyers see sophisticated procurement operations delivering consistent results, they see sustainable value, not just historical savings. They see a platform for continued improvement, not a squeezed lemon.

Resin Procurement Roadmap:

Measuring Success: KPIs and Benchmarks

Every PE firm tracks procurement metrics. But resin requires a different lens. Its volatility, technical complexity, and market opacity mean standard KPIs can mislead as easily as they inform.

The biggest challenge is understanding what the measurements actually mean in resin's unique context. A 10% cost reduction might be a home run in most categories, but if resin markets dropped 15% in the same period, you actually underperformed. On the other hand, holding prices flat while markets spike 20% represents massive value creation that traditional metrics might miss entirely.

Why Standard Procurement Metrics Fall Short for Resin

Most procurement scorecards treat all spend categories equally. But as we’ve already said many times at this point, resin is a different beast, so measuring it requires adjustments that can account for those unique dynamics.

The index relativity problem.

Unlike categories with stable baselines, resin prices swing wildly month to month. Absolute cost reduction means nothing without market context. You need to track your delta to index, not just your unit price. More importantly, you need to understand that different indices tell different stories—CDI might show flat while ICIS shows an increase. Which one's in your contract matters more than which one's "correct."

The grade complexity challenge.

When you're buying 50 different grades across multiple facilities, aggregated metrics hide critical details. That 5% overall savings might include 20% savings on commodity grades and 10% increases on specialties you couldn't avoid. Portfolio-level metrics need grade-level backup to be meaningful.

The total cost trap.

Resin savings evaporate quickly when you factor in processing changes. A 10% cheaper resin that runs 5% slower costs more in the long run. But most procurement dashboards don't capture these operational impacts until it's too late. You need metrics that span from supplier invoice to finished product.

Building Resin-Specific Performance Metrics

Of course, we’re not suggesting you should abandon traditional KPIs. We just recommend adapting them for resin's realities. For instance:

Track spreads, not just prices.

Your primary metric should be the spread between your price and relevant index benchmarks. But go deeper than that: track the spread between spot and contract prices, between different regions, and between virgin and recycled grades. These spreads reveal arbitrage opportunities that simple price tracking misses.

Best-in-class buyers can achieve 3-7% below index for commodity grades here, though specialties typically trade closer to index where volume provides less leverage.

Measure volatility capture.

In stable markets, steady pricing is good. In volatile markets, it might mean you're missing opportunities. Track what percentage of favorable market moves you capture versus unfavorable moves you avoid. Aim to capture the majority of market drops while avoiding most spikes, although the exact ratio depends on your risk tolerance and market position.

Monitor grade rationalization impact.

Every grade you eliminate improves leverage and reduces complexity. Track both the direct savings (often 5-10% from improved volume concentration) and indirect benefits: reduced inventory, simplified operations, fewer supplier touchpoints. But also track quality and performance metrics to ensure consolidation isn't creating hidden costs.

Create supplier scorecards that reflect resin realities.

OTIF matters, but so does allocation behavior during shortages. Likewise, price competitiveness matters, but so does transparency about market drivers. Build scorecards that capture both operational performance and strategic partnership value.

Example Resin Procurement KPI Framework:

The Metrics That Actually Predict Success

After analyzing dozens of PE resin procurement transformations, certain forward-looking metrics consistently separate winners from losers:

Contract coverage ratio.

What percentage of your volume is under contract versus spot? The sweet spot typically lands around 70-80%, leaving room to capitalize on spot opportunities while maintaining supply security. Too much coverage and you miss market drops. Too little and you're exposed to spikes.

Supplier concentration risk.

Track your top supplier's share of spend, but also track your top supplier's share of any single critical grade. Overall concentration might be acceptable at 40%, but if one supplier controls 90% of a grade you can't substitute, making you vulnerable.

Alternative qualification pipeline.

How many grades have qualified alternatives ready to go? This metric predicts your ability to respond to supply disruptions or price spikes. The strongest performers maintain alternatives for all commodity grades and at least half their specialties.

Market intelligence latency.

How quickly do you hear about market changes versus when they impact your prices? If you're learning about feedstock moves from supplier increase letters, you're already behind. Track the delta between market signals and your awareness of them.

Making Metrics Drive Action

The best dashboards don't just report history. They also trigger decision-making. For resin, that means building in automatic alerts and action triggers like, for instance:

• When your price exceeds index by 5%, automatic escalation to renegotiate
• When spot prices drop 10% below contract, trigger spot buy evaluation
• When a supplier's OTIF drops below 92%, initiate alternative supplier qualification
• When inventory turns drop below target, review safety stock levels

Obviously, these thresholds vary by grade, market conditions, and business requirements. So, the triggers for commodity PP in packaging won't match those for automotive specialties.

The Hidden Value of Predictive Metrics

Finally, most procurement dashboards are backwards-looking. But resin's volatility rewards teams that look forward. Therefore, you’ll want to track metrics that predict future performance:

• Feedstock spread indicators. The spread between ethylene and polyethylene, or propylene and polypropylene, predicts margin pressure on suppliers. When spreads tighten, suppliers push harder for increases.
• Capacity utilization rates. When industry utilization exceeds 85%, allocation risk rises. Below 75%, buyer power increases. This metric often predicts price direction better than current spot prices.
• Export arbitrage windows. When Asian prices exceed North American prices by more than shipping costs, domestic supply tightens. Track this spread as an early warning system.
• Forward curve slopes. When future prices are lower than current spot (backwardation), the market expects prices to fall. When future prices exceed spot (contango), expect upward pressure. These curves often move before spot prices, giving you a timing advantage.

Remember, the firms that win in resin procurement aren't necessarily those with the most metrics. Rather, they're the ones whose metrics account for resin's uniqueness and drive specific actions. Because in a market this volatile, measurement is most valuable when it gives you better signals than your competition.

Turn Procurement into an EBITDA Driver with ResinSmart

Every strategy in this guide becomes more powerful with real-time intelligence. Put differently, the difference between capturing modest savings and transformative results often comes down to information speed.

Yet most procurement teams still operate with tools built for a different era. Traditional spend analytics platforms can't interpret feedstock relationships, don't understand regional arbitrage, and miss allocation risks during supply crunches. They treat resin like any other commodity when we all know that couldn’t be further from the truth.

This information gap keeps procurement teams reactive, always responding to changes rather than anticipating them. In reality, the firms capturing the most value have already shifted to predictive intelligence, analyzing what's coming rather than focusing on what’s already happened.
