Resin Pricing Platforms Compared: What Buyers Should Know Before Subscribing

If you’re evaluating resin pricing platforms, you probably already know the options aren’t easy to compare side by side. One provider sells contract-grade benchmarks based on market surveys. Another publishes spot transaction data from its own trading desk. Then there’s the predictive analytics platforms with proprietary benchmarks and advisory support. It’s a lot to take in for a team sorting through all of today’s solutions.

They all call themselves “resin pricing data.” But what they actually deliver, and how useful that data is when you’re sitting across from a supplier pushing a 5¢ increase, can vary by huge amounts. And the differences start with understanding what type of product you’re actually looking at.

Key Takeaways

• "Resin pricing data" covers three fundamentally different product categories — index publishers, market data platforms, and procurement intelligence platforms — and most buyers need more than one.
• Survey-based indexes like CDI and ICIS anchor contracts but can lag actual market conditions by days or weeks. Transaction-based data from platforms like Resintel moves faster.
• No single platform covers every angle. The strongest procurement teams layer index benchmarks with spot data, feedstock tracking, and predictive analytics.
• When evaluating platforms, the most important questions are how the data is sourced, how often it updates, and whether it's built for buyers or serves both sides of the table.
• ResinSmart is the only platform that pairs transaction-based benchmarks and predictive analytics with hands-on procurement advisory — giving buyers both the data and the interpretation to act on it.

Three Types of Resin Pricing Intelligence

Before comparing individual providers, it helps to understand the category itself. “Resin pricing data” covers three fundamentally different products, and mixing them up is one of the most common mistakes buyers make when allocating their market intelligence spend.

Index Publishers

These produce survey-based benchmarks that anchor most contract pricing in the industry. CDI/ICIS and CMA/IHS fall here. Their numbers settle contracts and provide a shared reference point between buyers and suppliers. The methodology is well established, and nearly every contract-linked deal in North America references one of these indexes.

Market Data Platforms

These publish pricing derived from actual spot transactions, editorial research, or both. Plastics News and Resintel (powered by the Plastics Exchange) are the most recognized names. Their value is speed and a different vantage point: transaction-based or editorially sourced data that can move faster than survey-based indexes.

Procurement Intelligence Platforms

These go beyond publishing prices. They combine pricing data with analytics, forecasting, and advisory services designed to help buyers interpret signals and act on them. ResinSmart sits in this category.

Each of the three solves a different problem, and most procurement teams that manage resin well draw from more than one. The question is which combination fits your operation and the decisions you actually need to make. Our resin index alternatives piece goes deeper on the specific signals that move before indexes do and how to use them in negotiations.

How the Major Resin Pricing Platforms Compare

Each of these platforms shows up in procurement conversations for different reasons, and understanding what each one actually delivers helps you figure out where your current setup has gaps.

ICIS / CDI

ICIS acquired Chemical Data (CDI) in 2020, and while the CDI brand still appears in contracts across the continent, the two now operate under one roof. Together, they represent the dominant survey-based index in North American resin markets.

What they do well: Broad coverage across PE, PP, PS, PVC, PET, engineering resins, and feedstocks. CDI benchmark prices have anchored supplier contracts since 1979, which means their numbers carry weight in any negotiation simply because both sides recognize them. ICIS adds global coverage, forward curves, and analytical commentary that connects international movements to domestic pricing.

Where the gaps show up: The methodology relies on voluntary surveys from producers, distributors, and select buyers, which means published prices can lean toward reported offers rather than closed transactions. Update cadence is weekly or monthly, so in fast-moving markets, the benchmark may lag actual conditions by days or weeks. And non-market adjustments can keep published prices elevated even after spot conditions have softened.

Best fit: Teams whose contracts frequently reference CDI or ICIS. Yes, you need access to what they publish, but treat it as a starting point, not a complete picture.

IHS Markit / S&P Global (Chemical Market Analytics by OPIS)

IHS Markit — now part of S&P Global — offers polymer pricing through its Chemical Market Analytics (CMA) division, formerly CMAI. The brand has gone through several name changes, but the product remains a fixture in upstream and international sourcing.

What they do well: Strong feedstock and petrochemical coverage extending into ethylene, propylene, and monomer economics. Capacity databases and supply/demand balances help buyers understand the production side. International coverage is broad, particularly for teams sourcing across regions.

Where the gaps show up: Similar survey-based methodology to ICIS/CDI, with the same lag and potential bias to stay aware of. North American buyer-side coverage is thinner for many commodity resin grades. And the S&P Global umbrella means this data often comes bundled with broader chemical intelligence packages that push costs above what a mid-market processor needs.

Best fit: Buyers with upstream exposure, international sourcing needs, or contracts indexed to IHS/CMA benchmarks.

Plastics News

Plastics News publishes weekly spot pricing summaries across commodity and engineering resin grades, sourced through editorial research, including phone calls to processors, producers, consultants, and analysts. It’s been a staple reference for the industry since 1989.

What they do well: Accessible, widely read, and editorially independent. Pricing data covers both commodity and high-temperature thermoplastics across two volume tiers, and the weekly cadence provides a useful pulse check between monthly index publications. The editorial team discloses its sourcing methodology, which is more transparency than most index publishers offer.

Where the gaps show up: Plastics News itself discourages using its pricing chart alone to structure contracts. The data is directional, useful for trend confirmation and cross-referencing, but it lacks the granularity and contractual weight of CDI or ICIS benchmarks. So there’s no forecasting, advisory, or transaction-level detail.

Best fit: A solid supplementary source for any procurement team. Good for cross-referencing index movements and staying current on market direction. But it won’t replace a primary benchmark or help you build a negotiation strategy.

Resintel / The Plastics Exchange

Resintel is the market intelligence arm of The Plastics Exchange, which has operated as North America's primary spot trading platform for commodity-grade PE and PP since the late 1990s. Because The Plastics Exchange facilitates actual resin transactions, Resintel's pricing data is rooted in deal flow rather than surveys, giving it a fundamentally different starting point than the index publishers above.

What they do well: Transaction-based pricing across nine proprietary PE and PP indices, published daily. Weekly Resinsights reports (syndicated through PlasticsToday) combine pricing data with supply/demand analysis and market commentary. An interactive production map tracks North American plant capacities and operating status. Because the data reflects what’s actually trading, it often moves faster than survey-based indexes.

Where the gaps show up: Coverage is concentrated in commodity PE and PP, so if your portfolio includes resins like PS, PVC, PET, ABS, nylon, or polycarbonate, you'll need another source for those grades. There's no predictive forecasting or advisory component, either. And because The Plastics Exchange operates as a spot marketplace, listed prices may not directly reflect what your supplier will offer at your volume.

Best fit: PE and PP buyers who want transaction-based spot data as a complement to their index benchmarks. The daily pricing cadence is valuable for tracking spot-contract spreads, which is one of the strongest negotiation signals available to mid-market buyers.

ResinSmart

ResinSmart is a buyer-side procurement intelligence platform powered by RTi (Resin Technology Inc.), a firm with over 27 years in the resin advisory space and visibility into 3B+ pounds of transactional data. Unlike the providers above, ResinSmart combines market analytics with hands-on procurement advisory, which puts it in a fundamentally different product category.

What that looks like in your operations:

• Transaction-based benchmarks built from actual buyer-seller data, not surveys
• Predictive forecasting that translates market signals into directional guidance on timing and positioning
• Supply/demand dashboards covering commodity and engineering resins
• Hands-on advisory from experienced resin procurement advisors who provide grade-level negotiation support, contract review, and supplier strategy alongside the analytics

That pairing of data with human interpretation is what separates a procurement intelligence platform from a data feed you have to figure out on your own. If your biggest challenge is knowing whether a supplier's price increase is justified and how to respond, this is the category built for that question. That said, every procurement team's needs are different, so it's always worth doing your own evaluation to find the combination of tools that fits your operation best.

How to Evaluate a Resin Pricing Platform

The right platform depends on what decisions you’re making and what gaps exist in your current intelligence. A few areas worth considering before you commit budget:

• Data methodology: Surveys, transactions, editorial research, or a blend? Each carries different trade-offs in speed, accuracy, and bias.

• Update frequency: Weekly index publications worked when markets moved quarterly. How current does your data need to be for the decisions you’re actually making?

• Buyer vs. supplier orientation: Some platforms serve both sides. Others are built for buyers specifically. That orientation shapes which signals get prioritized.

• Coverage breadth: PE and PP only? A commodity-focused platform may work. Engineering resins and feedstocks too? You’ll need broader coverage.

• Advisory component: Do you have internal expertise to interpret the data? If not, analytics paired with human guidance will deliver more than raw numbers alone.

• Contract relevance: Which index do your contracts reference? You need that benchmark regardless of what else you layer on top.

See Where Your Resin Pricing Actually Stands with ResinSmart

The resin pricing indexes your contracts reference aren't going anywhere, and you'll always need access to them. But they're one input. Spot data, transaction benchmarks, and predictive analytics all fill in parts of the picture that surveys miss. The question is how much of that assembly you want to do yourself.

ResinSmart brings all of it together — the benchmarks, the forecasting, the market context — and pairs it with advisors who've spent decades helping buyers negotiate resin. So when the next increase letter shows up, you already know whether the number holds up and exactly how to push back.

Resin Pricing Platforms: Frequently Asked Questions

How can you tell whether a resin pricing platform reflects what buyers are actually paying?

Whether a resin pricing platform reflects what buyers are actually paying comes down to how the data is sourced. Survey-based indexes compile reported prices from market participants, which can skew toward supplier offers rather than closed deals. Transaction-based platforms pull from actual buyer-seller trades at specific volumes. The closer the data sits to a real purchase order, the more likely it reflects what your market actually looks like.

Can a resin pricing platform help validate a supplier price increase?

A resin pricing platform can absolutely help validate whether a supplier's proposed increase is supported by actual market conditions. When an increase letter arrives, you need to know whether feedstock costs moved enough to justify the number, whether spot prices support the claim, and how the proposed increase compares to what other buyers are paying. A platform with current benchmarks and feedstock tracking answers all three within hours.

What’s the difference between transaction-based resin pricing and a price assessment or index?

Transaction-based resin pricing comes from actual trades at specific grades, volumes, and dates. A price assessment or index, by contrast, is a survey-derived estimate of where the market sits, compiled from reported offers, bids, and selected transactions. Transaction data tells you what buyers paid. An index tells you what the publisher believes the market average looks like.

Do resin pricing platforms cover both spot and contract pricing?

Resin pricing platforms typically cover either spot or contract pricing in depth, not both. Index publishers like ICIS/CDI focus on contract-grade benchmarks. Resintel focuses on spot. ResinSmart covers both through transaction-based benchmarks and contract advisory. Tracking the spot-contract spread is one of the most useful ways to identify when your contract terms have drifted from where the market actually trades.

How current should resin pricing data be?

Resin pricing data should be updated at least weekly for most procurement decisions, though daily data is better when markets are volatile. Annual budget planning can work from monthly numbers. But if you're responding to a mid-month price increase or deciding whether to pull forward volume ahead of a supply disruption, weekly or daily signals are the minimum you need to make a confident call.

Is one resin pricing platform enough, or should buyers use multiple sources?

One resin pricing platform is usually not enough for buyers who want a complete market picture. Your contracts reference an index, so you need that index. But you also need something faster and more granular to validate what it's telling you. The strongest procurement teams layer in spot data, feedstock tracking, and predictive analytics alongside their primary benchmark.
