What's driving sentiment this week:
Latest published data (2025-07 to 2026-06) — Sentiment: Bullish
The most recent published customs observation for HS 293090 is 2026-06 at USD 9,911/ton, +16.4% against the previous month and -5.5% against 2025-07.
Reported volume across the fixed 13-economy panel was 95,624 tonnes over the window, 7,969 tonnes a month on average, and the three-month trend is +13.6%.
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.
Coverage note: HS 293090 is the residual line for organo-sulphur compounds; antioxidant thioesters are one small part of a very wide heading that also carries high-value pharmaceutical and agrochemical intermediates.
How About the Price?
Data source: UN Comtrade monthly trade statistics (https://comtradeapi.un.org/public/v1/preview/C/M/HS?period=202606&cmdCode=293090&partnerCode=0&flowCode=X&includeDesc=true) | Last updated: 2026-09-23
Price Trajectory, latest 12 months (2025-07 to 2026-06)
The monthly customs export unit value for HS 293090 moved from USD 10,489/ton in 2025-07 to USD 9,911/ton in 2026-06 (-5.5% across the window). The window high was USD 10,489/ton in 2025-07 and the low USD 7,458/ton in 2025-11. Three-month averages put the latest quarter +13.6% against the previous one, which is classified here as bullish.
The same panel reported USD 829.5 million of export value on 95,624 tonnes over the twelve months, an average of 7,969 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.
Supply-side factors
- Fixed reporting panel of 13 economies: AUS, BRA, CAN, CZE, DEU, GRC, HUN, IDN, MYS, NLD, POL, IND, GBR. 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 7,458 to USD 10,489/ton.
- Latest month, 2026-06: USD 9,911/ton, +16.4% against the previous month, on 8,478 tonnes.
Demand-side factors
- Thioester demand sits inside polymer stabiliser packages: DLTDP and DSTDP act as secondary antioxidants alongside hindered phenols in polyolefins.
- Upstream feedstock pages on this site: Polyethylene and Polypropylene.
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. Coverage note: HS 293090 is the residual line for organo-sulphur compounds; antioxidant thioesters are one small part of a very wide heading that also carries high-value pharmaceutical and agrochemical intermediates.
Substitutes & Alternatives
| Substitute | Replacement Scenario / How It Substitutes |
|---|---|
| Hindered Phenol Antioxidants (e.g., Irganox 1010, Irganox 1076) | Used as primary antioxidants in polyolefin stabilization. Thioesters (DLTDP, DSTDP) function as secondary (peroxide-decomposing) antioxidants and are typically used in combination with hindered phenols; in some formulations, higher loadings of hindered phenols alone can partially replace the thioester component, though synergistic performance is usually lost. Requires reformulation of the stabilizer package. |
| Phosphite Antioxidants (e.g., Irgafos 168, Weston 399) | Phosphites also act as hydroperoxide decomposers (secondary antioxidants) in polymer stabilization, directly competing with thioesters in polyolefins, polyurethanes, and adhesives. They are often preferred when color stability is critical, as phosphites cause less discoloration than sulfur-based compounds. Drop-in substitution at equivalent molar loading is feasible in many polyolefin applications. |
| 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.
