RawSource Bulk Chemical Price Index — July 2026

A supplier tells you the market “moved,” and the number on your renewal quote is 12% higher than last quarter. Was that the market, or was that the seller? Without an independent read on where bulk chemical prices are heading, every RFQ negotiation starts from the counterparty’s version of reality. This index gives you a second opinion, built entirely from public data you can check yourself.

The short version: through May 2026, the U.S. chemicals complex is broadly firmer, and the organics side is running hot. The BLS Producer Price Index for basic organic chemicals rose about 21% over the three months to May 2026 and about 18% year-on-year, dragging up solvents and glycols.

Inorganics are calmer: caustic soda and sulfuric acid are firm, hydrochloric acid is up year-on-year but flat lately, and methanol is the clear outlier, softening on ample supply. Everything below is directional market commentary with an as-of date, not a RawSource price quote.

Key takeaways

• The organic-chemical complex is the story this month: BLS PPI for basic organic chemicals is up roughly 21% over three months and 18% year-on-year to May 2026, so budgets built on late-2025 solvent and glycol numbers are already stale.
• Acetone and propylene glycol saw the sharpest moves up, on production outages and firmer propylene-based feedstock costs; methanol and isopropyl alcohol are the two that softened.
• Chlor-alkali products (caustic soda, sodium hypochlorite) are firm on tight operating rates; sulfuric acid is up strongly year-on-year but nearly flat month-on-month.
• Use this as a negotiation cross-check, not a purchase price. Index levels are not comparable across commodities; only each series’ own percentage change carries meaning.

July 2026 price-trend snapshot

The table reads as the most recent public direction for each commodity, the main driver behind it, and the as-of date of the read. Direction is the recent trend, not a forecast.

Two commodities in that table carry real search demand from buyers pricing renewals right now, methanol and sulfuric acid, and they are moving in opposite directions this month. That divergence is the single most useful thing in the snapshot: “chemicals are up” is true in aggregate and wrong for methanol.

What the federal price data shows

The Producer Price Index is the cleanest free anchor available, published monthly by the U.S. Bureau of Labor Statistics and mirrored on the St. Louis Fed’s FRED service. It measures U.S. producers’ selling prices, so it tracks the wholesale level a distributor buys at, one step upstream of your delivered cost. The readings below are for May 2026, the latest month available at this publication, and BLS flags May as preliminary.

Read the columns, not the rows against each other. The organic index climbing about 21% in a quarter while the inorganic-acids index barely moved (+1.7%) tells you where the pressure is concentrated: on the carbon side of the catalog. A buyer whose spend is weighted toward solvents, glycols and their derivatives is absorbing a very different market than one buying acids and alkalies. Weight your own basket before you conclude the market did anything to you.

Movers and shakers

Acetone led the upside. U.S. supply tightened through the spring on overlapping production outages and planned maintenance, with strong export pull from Europe and Latin America. Public spot assessments put acetone near $1,547 per metric ton FOB U.S. Gulf Coast in mid-April 2026, and one source recorded a roughly 32% jump in late March, per market reporting. Benzene and propylene feedstock costs kept a floor under it. If acetone is in your solvent slate, this is a month to lock volume rather than ride spot.

Propylene glycol firmed on feedstock and a producer move. North American propylene glycol sat near $1.92 per kilogram in May 2026, and a major North American producer announced an increase effective early June, per trade sources. The driver is propylene-oxide cost, so PG and other propylene derivatives tend to move together. Ask your supplier to separate the feedstock pass-through from margin when the increase letter arrives.

Caustic soda and sodium hypochlorite stayed firm. Caustic ran up about 3.7% in the U.S. in mid-March on tight global supply and import-logistics friction, per ChemAnalyst, and the BLS caustic series is up 8.7% year-on-year.

Because hypochlorite is made from chlorine and caustic, its roughly 4.7% rise from December to March tracks the same chlor-alkali economics. Water-treatment and cleaning buyers should read caustic and hypochlorite as one linked exposure; the full basket those plants buy is broken down in our water treatment chemicals guide.

Glycerin and citric acid held a firm bias. Refined glycerin in North America rose on tight supply and steady demand from pharma and personal care, with one index up about 10% quarter-on-quarter in Q1, per ChemAnalyst. Citric acid sat near $671 per metric ton in April and ticked up about 1% in late May on corn-linked cost and logistics, per market data.

Methanol and IPA were the exceptions down. Methanol softened through June, with spot off sharply over the trailing month on ample supply and thin downstream demand, per Trading Economics; Methanex posted a European contract reference of €915 per metric ton for the July-to-September window.

Isopropyl alcohol drifted around $1,320 to $1,360 per metric ton in Q1 as solvent and disinfectant demand stayed cautious, per market reporting. These two are the reason a blanket “prices are rising” surcharge deserves a challenge.

The organic-chemicals run, in detail

The one number worth carrying into your next budget review is the basic-organic-chemicals index: up about 21% in three months and 18% over the year to May 2026. That is not a normal quarter. It reflects three forces stacking at once. Feedstock cost is the base layer, with benzene and propylene supporting downstream solvents and glycols. Supply disruption is the accelerant, as spring outages and turnarounds in the U.S. removed acetone and derivative volume from an already-snug market. Trade and logistics friction sits on top, firming import replacement costs.

For a container-volume buyer, the practical risk is basis, not just level. When an index moves this fast, contract formulas priced off a lagging reference can drift well away from spot in either direction, and the gap is where disputes start.

Two defenses are worth setting up this month. First, pin every renewal to a named public reference with a stated lag, so both sides argue about the same number. Second, widen your safety-stock band on the organics that moved hardest, acetone and the glycols, because a snug market punishes just-in-time buyers when the next outage lands. The honest limitation: PPI is a national producer average with a reporting lag, so it tells you direction and rough magnitude, not the delivered number on your lane in a given week.

What this means for your next RFQ

The BLS series measure the U.S. market, and the drivers this month are global: chlor-alkali tightness and shipping friction abroad feed U.S. import parity, while feedstock swings move with crude and gas. That is why a domestic-average index and a landed spot quote can disagree, and both can be right. Treat this index as the macro backdrop and your own lane quotes as the ground truth.

Three actions turn this into negotiating room. Benchmark any increase letter against the matching PPI series before you accept it; a 15% ask against a series up 6% is a conversation, not a fact. Separate feedstock pass-through from margin, especially on propylene derivatives like propylene glycol and acetone where the feedstock story is public.

Then time your buys against the divergence: lock the sharp movers, and stay short on the softening ones like methanol until the trend confirms. For the broader sourcing mechanics behind these calls, our bulk buying and grade guide walks through how specification and origin change a delivered number as much as the index does.

RawSource supplies these commodities from U.S. stock at drum, tote and bulk volume, including Sulfuric Acid 93%, Caustic Soda Beads, Sodium Hypochlorite, Citric Acid and Propylene Glycol, across water treatment and industrial manufacturing. Send your commodity, grade and volume, and request a current quote for your lane.

Methodology and sources

The authority backbone is the U.S. Bureau of Labor Statistics Producer Price Index (commodity series), read through the St. Louis Fed’s FRED service and current to May 2026, the latest month published at the time of writing. BLS marks May 2026 preliminary and revises for up to four months, so treat the newest reading as provisional. Percentage changes (month-on-month, three-month, year-on-year) were computed by RawSource from the published index values; the index levels themselves use different base periods across series and are not comparable to one another.

Per-commodity spot direction and drivers are drawn from public market-intelligence pages, each linked and dated inline: Methanex posted prices, Trading Economics, ChemAnalyst, and businessanalytiq. Every figure is a range or an approximate public indication as of the stated date, offered as directional market commentary. Nothing here is a RawSource offer, a guarantee of availability, or a price quote for any transaction. This index updates monthly.

Frequently asked questions

Are these RawSource’s prices?

No. This is a market index built from public data, the U.S. BLS Producer Price Index plus public market-intelligence pages, to show where bulk chemical prices are heading. It is directional commentary, not an offer or a quote. For a price on a specific commodity, grade, volume and delivery lane, request a current quote.

How current is the data?

The BLS Producer Price Index anchor is current to May 2026, the latest month available when this July 2026 edition published, and BLS flags that month as preliminary. Per-commodity spot indications carry their own as-of dates, ranging from Q1 2026 to late June 2026, shown in the snapshot table and inline. The index refreshes monthly.

Why is methanol falling when most chemicals are rising?

Methanol runs on its own supply-and-demand balance. Through June 2026 the market carried ample supply against muted downstream demand, which softened spot even as feedstock-driven organics like acetone and the glycols rose. It is a useful reminder that “the chemicals index is up” does not mean every molecule is up.

Why does a national index disagree with my delivered quote?

The Producer Price Index is a U.S. producer-level average with a reporting lag, one step upstream of your delivered cost and blind to your specific grade, packaging, origin and freight lane. Use the index for direction and rough magnitude, and use your own quotes for the actual number. When they diverge sharply, that gap is usually freight, grade or import parity, and it is worth asking your supplier to itemize.

How should I use this index in a negotiation?

Match each increase request to the corresponding PPI series and compare the magnitudes. An ask well above the matching series’ move is a starting point for discussion, not a settled cost. Pair that with a named public reference and a stated lag in your contract so both sides price off the same number.
