What's driving sentiment this week:
Latest published month (2026-07) — Sentiment: Neutral
The most recent published customs observation for HS 293090 is 2026-07 at USD 7,935.39/ton, +31.2% against the previous month and +4.4% against 2025-08.
Reported volume across the fixed 15-economy panel was 107,484 tonnes over the window, 8,957 tonnes a month on average, and the three-month trend is -11.5%. The heading-level series is volatile: the largest month-on-month move in the window was +31.2% between 2026-06 and 2026-07, when reported value moved -26.4% and reported tonnage moved -43.9%, so that move reflects the mix and size of shipments filed under this heading rather than a single quoted price.
Next 1–3 Months — Outlook
This page is refreshed from public customs statistics rather than paid price assessments, so the next revision will roll in each newly published month for HS 293090. Direction shown here is a reading of published customs unit values, not a forecast.
Key Market Impact
Customs unit values for this heading are the single most checkable price signal available without a subscription: they combine the product mix actually crossing borders, the average contract level behind those shipments and freight-relevant volume. Treat them as the trade-weighted baseline for the heading, and read the coverage note above before applying them to a single grade.

Demand-side factors
- Thioester demand is as a secondary antioxidant for polyolefins and elastomers, where the thiodipropionate esters decompose the hydroperoxides formed during processing and service, plus smaller volumes as lubricant and grease additives and as intermediates in agrochemical and pharmaceutical synthesis, so its call tracks polyolefin and rubber compounding volumes.
- Related market pages on this site: Polyethylene (the polyolefin the antioxidant protects), Polypropylene (the other polyolefin in the same compounds), Phenol (the hindered phenol the thioester is used alongside).
Price Trajectory, latest 12 months (2025-08 to 2026-07)
The monthly customs export unit value for HS 293090 moved from USD 7,603.34/ton in 2025-08 to USD 7,935.39/ton in 2026-07 (+4.4% across the window). The window high was USD 10,319.09/ton in 2025-10 and the low USD 6,048.80/ton in 2026-06. Three-month averages put the latest quarter -11.5% against the previous one, which is classified here as neutral. The heading-level series is volatile: the largest month-on-month move in the window was +31.2% between 2026-06 and 2026-07, when reported value moved -26.4% and reported tonnage moved -43.9%, so that move reflects the mix and size of shipments filed under this heading rather than a single quoted price. One filing distorts 2026-06: Germany declared 10,670 tonnes under this heading at USD 3,285.76/ton, against a monthly norm of about 1,915 tonnes for that reporter across the rest of the window and a panel median of USD 10,956.50/ton in the same month, so the flow carries 63% of the panel's tonnage that month. The 2026-06 aggregate of USD 6,048.80/ton is therefore a reporting artefact inside the heading rather than a price observation, and the direction label is not taken from a three-month average that contains it.
The same panel reported USD 889.6 million of export value on 107,484 tonnes over the twelve months, an average of 8,957 tonnes a month. Values are customs returns for the stated HS heading, so they capture the traded mix of that heading rather than a single quoted grade.
The EU side of the same heading is one month fresher than the panel above: Eurostat Comext records EU27 imports of HS 293090 from outside the EU at USD 6,151.83/ton in 2026-08 (EUR 5,306.46/ton at the ECB monthly reference rate), +41.7% against 2026-07, on 10,096 tonnes; the twelve months to 2026-08 totalled 134,146 tonnes. On the 12 months the two datasets share (2025-08 to 2026-07), three-month blocks that far apart moved -21.5% on the export panel and -12.1% on the EU import side, so the two agree on direction. Import values are recorded on a CIF-type basis by a single bloc, so the level is not comparable with the export panel — the comparison above is directional.
2026-08 is deliberately not in the series: of the 15 economies that make up this page's fixed panel, 13 had filed both value and net weight for this heading when the page was rebuilt on 2026-11-03, while the heading drew 18 filers in total that month; 2026-09 drew 0 filings for this heading, 0 of them from panel members, and 2026-10 drew 0 (0 from the panel). Splicing a partly-filed month onto a fixed panel would move the unit value through composition alone, so the window stays at 2026-07 until the whole panel for 2026-08 has reported.
HS 293090 is the residual organo-sulphur line, 'n.e.c. in heading 2930', so it carries the thioester antioxidants together with rubber accelerators, thiochemicals and other sulphur compounds that have no dedicated six-digit line; the dithiocarbamates are separated in 293020, the thiuram sulphides in 293030, methionine in 293040 and thiodiglycol in 293070. The unit value therefore describes a broad organo-sulphur composite and cannot be read as a price for a single thiodipropionate grade.
Supply-side factors
- Fixed reporting panel of 15 economies: AUS (36), BRA (76), CAN (124), CZE (203), FIN (246), DEU (276), GRC (300), GTM (320), HUN (348), IDN (360), MYS (458), NLD (528), POL (616), IND (699), GBR (826). The panel is held constant in every month of the window so month-to-month movement is not a composition effect.
- Monthly unit value range over the window: USD 6,048.80 to USD 10,319.09/ton.
- Latest month, 2026-07: USD 7,935.39/ton, +31.2% against the previous month, on 9,494 tonnes.
Basis: these are customs unit values for the stated HS heading, not quoted spot, contract or assessed prices, and no paid price assessment is used or redistributed on this page. Every figure can be re-checked at the API links listed at the end of this page.

Substitutes & Alternatives
| Substitute | Replacement Scenario / How It Substitutes |
|---|---|
| Oxygen Esters (conventional carboxylate esters) | In lubricant and plasticizer applications where thioester reactivity or sulfur content is undesirable, conventional oxygen esters (e.g., dioctyl sebacate, trimethylolpropane trioleate) can substitute. They lack the antioxidant and extreme-pressure properties of thioesters, so substitution is limited to applications where those functions are not required. Generally a drop-in replacement from a compatibility standpoint. |
| Zinc Dialkyldithiophosphates (ZDDP) | In lubricant additive packages, ZDDP provides both antioxidant and anti-wear performance, overlapping with the hydroperoxide-decomposing role of thioesters. ZDDP can replace thioesters in engine oil and gear oil formulations, though it introduces zinc and phosphorus, which may be restricted in low-SAPS (sulfated ash, phosphorus, sulfur) specifications. Partial replacement requiring additive package rebalancing. |
| Thioethers (dialkyl sulfides, e.g., dioctadecyl sulfide) | Simpler thioether compounds can substitute for thioesters as secondary antioxidants in polymer applications where the ester linkage is not needed for compatibility or solubility. They offer similar sulfur-based peroxide decomposition but generally lower efficiency per unit sulfur. Used as cost-driven partial substitutes in commodity polyolefin stabilization. |
| Acyl-CoA analogs / Acyl-N-acetylcysteamine thioesters (biochemical/pharma) | In biochemical research and pharmaceutical synthesis where acyl-CoA thioesters are used as acyl-transfer agents, synthetic surrogates such as acyl-N-acetylcysteamine (SNAC) thioesters or acyl pantetheine analogs can substitute. These are more stable and easier to handle than acyl-CoA itself. Substitution requires validation of enzymatic or chemical reactivity equivalence; not a drop-in replacement but a functional analog widely accepted in biosynthetic studies. |
| Flavoring Esters (ethyl acetate, isoamyl acetate, etc.) | In food flavoring applications where thioesters contribute roasted, meaty, or sulfurous aroma notes, conventional oxygen esters (fruity/sweet notes) can substitute only when the target flavor profile is changed. This is not a direct functional replacement but an alternative when sulfur-containing notes are reformulated out of a flavor system. Requires full sensory and regulatory reformulation. |

Key Influence Events
Thioesters are a class of organic compounds in which the oxygen atom of a conventional ester linkage (–C(=O)–O–) is replaced by a sulfur atom, giving the general structure R–C(=O)–S–R'. They occur naturally in biological systems (notably as acyl-CoA thioesters, central intermediates in fatty acid and acetyl metabolism) and are produced synthetically for use as lubricant additives, polymer stabilizers, antioxidants, flavoring agents, pharmaceutical intermediates, and specialty chemical building blocks. Common commercial examples include dilauryl thiodipropionate (DLTDP), distearyl thiodipropionate (DSTDP), and dimyristyl thiodipropionate (DMTDP), which are widely used as secondary antioxidant co-stabilizers in polyolefins and other polymers. Thioesters are generally more reactive than their oxygen-ester counterparts due to the lower resonance stabilization of the C–S bond, making them valuable acyl-transfer agents in both industrial synthesis and biochemistry.
