n-Butane is the primary raw material for MAH production (~85% of global capacity uses the butane oxidation route). Chinese butane comes from LPG refinery streams and is priced against propane/LPG benchmarks correlated to crude oil. A $10/bbl crude swing translates to roughly $30–60/MT change in Chinese MAH production cost. Crude oil price is therefore the single most important short-term MAH price driver.

MAH production requires substantial energy for the high-temperature oxidation reactor (350–450°C), air compression, and product distillation. Chinese electricity and natural gas price fluctuations - particularly the power rationing events seen in 2021–2022 in Jiangsu and Shandong (key MAH production provinces) - can force curtailment and cause spot price spikes of 20–40% above normal levels within weeks.

China has added significant MAH capacity over 2015–2024, contributing to structural price pressure. New plant additions tend to create temporary oversupply and price weakness. When new capacity is absorbed by demand growth - typically within 12–18 months - prices recover. Monitoring announced Chinese capacity expansion projects is one of the most useful medium-term price indicators available to MAH buyers.

MAH as a Class 4.1 DG solid adds freight surcharges beyond standard container rates. China-to-Europe container rates have swung from ~$800/20ft (2019) to >$12,000 (2021 peak) to ~$2,000–4,500 (2024–2025 range). DG surcharges add $150–400/20ft independently of market. At 14.5 MT per 20ft container of bags, freight adds $60–200/MT to the FOB price - a significant but manageable component.

UPR - which consumes ~45% of global MAH - has strong construction and marine seasonality. Demand peaks in Q1–Q2 (spring construction season, Northern Hemisphere) and again pre-winter (Q3). Buyers who lock in annual contracts or place orders in Q4 (October–January, the weakest demand quarter) typically achieve 8–15% lower prices than peak-season spot buyers.

China's ongoing environmental inspection and closure campaigns ("Blue Sky" programme) periodically shut down non-compliant MAH plants, particularly smaller benzene-route producers. These closure events can tighten supply rapidly and cause short-term price spikes of 10–25% before compliant producers ramp up. The trend toward larger, more efficient butane-route plants ultimately increases supply security but creates transitional volatility.

The quality gap between Chinese and Western MAH that existed pre-2015 has been substantially closed at qualified producers. Chinese MAH from leading Shandong and Jiangsu producers now routinely achieves:

• Purity ≥99.5% (premium grade) - matching Western specification
• APHA ≤10 (molten at 70°C) - gel-coat UPR quality
• Fe ≤1 ppm - organometallic and SMA personal care grade
• Crystallisation point ≥52.6°C - consistent purity indicator
• Maleic acid ≤0.1% - moisture-controlled packaging and storage

1. Request batch COA and SDS from Sinolook; verify crystallisation point, APHA, purity, and Fe meet your specification
2. Order qualification sample (1–5 kg); run incoming QC: crystallisation point, APHA, maleic acid content
3. Run parallel synthesis trial: produce UPR, HPMA, or SMA using Chinese MAH alongside your current MAH source; compare AN, colour, and product performance
4. Conduct application performance test (UPR gel time, hardness, colour; HPMA scale inhibition performance; SMA Tg)
5. Approve Chinese MAH as alternate/primary source; update approved vendor list; request REACH OR letter and TSCA cert from Sinolook for compliance documentation

Q1: What is the current price of maleic anhydride?

As of early 2025, indicative prices for maleic anhydride (CAS 108-31-6) from Chinese producers are approximately: Standard grade (purity ≥99.0%, APHA ≤30): $800–1,100/MT FOB China in 25 kg bags; Standard grade big bags (500/1,000 kg FIBC): $750–1,050/MT FOB China; Premium low-colour grade (APHA ≤10, Fe ≤1 ppm): $1,000–1,350/MT FOB China; Molten ISO tank (standard grade): $700–980/MT FOB China. Western-origin MAH (Huntsman, Lanxess in Europe; Bartek, Polynt in North America) is significantly more expensive - typically $1,400–2,200/MT delivered, representing a 30–50% premium over Chinese-origin equivalents after freight. Prices fluctuate with n-butane/crude oil costs, Chinese energy pricing, seasonal UPR demand, and freight rates.

Q2: What drives maleic anhydride price volatility?

MAH price volatility is driven by five primary factors: (1) n-Butane / crude oil price: The primary feedstock for ~85% of global MAH production is n-butane (from LPG). Crude oil and LPG price swings of $10–15/bbl translate to $30–70/MT changes in MAH production cost and are rapidly reflected in Chinese FOB prices; (2) Chinese energy costs: MAH production is energy-intensive; Chinese electricity and gas prices - and periodic power rationing events in key production provinces (Shandong, Jiangsu) - can cause sudden supply curtailments and 15–30% price spikes; (3) UPR seasonal demand: UPR (45% of MAH demand) has construction and marine seasonality, with demand peaks in Q1–Q2 and Q3 and troughs in Q4. Prices typically follow this seasonal pattern by 4–8 weeks; (4) Chinese capacity additions: New plant announcements in China create forward price pressure; capacity coming online creates temporary oversupply until absorbed by demand growth; (5) Freight rates: Container shipping rates from China to Europe/Americas have been volatile (from $800 to $15,000/20ft between 2019–2021), and add $60–200/MT to the delivered cost of Chinese MAH. The net effect is that MAH prices can swing ±20–30% over a 12-month period driven by these overlapping factors, making annual contract pricing attractive for buyers who value stability.

Q3: Is Chinese maleic anhydride the same quality as Western-origin MAH?

Yes - at qualified Chinese producers, maleic anhydride quality is now equivalent to Western-origin material at comparable specification levels. Both Chinese and Western MAH have CAS 108-31-6 and are produced by the same catalytic n-butane oxidation technology (VPO catalyst, 350–450°C). The key QC parameters - purity ≥99.0–99.5%, crystallisation point ≥52.5°C, APHA colour ≤10–30, Fe ≤1–5 ppm, maleic acid ≤0.1–0.3% - are achievable by leading Chinese producers and are verified on the batch COA with each shipment. The historical quality gap between Chinese and Western MAH existed primarily in the 2005–2015 period when Chinese production was dominated by smaller benzene-route plants with less sophisticated quality control. The modern Chinese MAH industry, producing predominantly via butane route with advanced distillation and packaging systems, delivers product fully equivalent to Western material at the specification levels required by UPR, SMA, HPMA, and grafting applications. Sinolook Chemical sources exclusively from qualified producers with consistent batch QC and retention sample capability, and provides full documentation (COA, SDS, REACH OR, TSCA cert) to support buyers' quality management systems.

Q4: What is the maleic anhydride price per kg?

Converting from per-tonne to per-kg pricing: Chinese-origin standard grade MAH at $800–1,100/MT translates to approximately $0.80–1.10 per kg FOB China. Premium low-colour grade at $1,000–1,350/MT is approximately $1.00–1.35 per kg FOB China. After adding freight and DG surcharges for delivery to Europe (approximately $100–200/MT), the CIF Europe equivalent is approximately $0.90–1.30/kg for standard grade and $1.10–1.55/kg for premium grade. For comparison, Western-origin MAH delivered in Europe is typically $1.40–2.00/kg. For small orders (1–5 MT in 25 kg bags), the per-kg equivalent is at the upper end of the range; for large orders (≥18 MT in ISO tank), the lower end applies. Note that MAH is sold and priced by weight (per MT or per kg), not by volume - the relevant reference is always the net weight, as MAH is a dense material (1.48 g/cm³ solid) that takes up less physical space than its weight might suggest.

Q5: Will maleic anhydride prices increase in 2025–2026?

The medium-term MAH price outlook for 2025–2026 is moderately constructive - meaning prices are more likely to be stable to higher than meaningfully lower, based on the following supply-demand dynamics: Demand support: Broad-based demand growth of +3–5% p.a. from UPR (construction and composites), SMA (EV battery components, paper sizing), and MAH-grafted polyolefins (automotive lightweighting) provides a structural demand floor. Supply constraints: Chinese environmental inspections continue to limit expansion of non-compliant benzene-route capacity; new butane-route capacity additions are being absorbed rapidly. Feedstock risk: Crude oil and LPG price uncertainty - particularly from geopolitical events affecting Middle Eastern LPG supply - could push Chinese production costs higher. Downside risks: A significant global economic slowdown reducing construction and automotive output (the key UPR and composite markets) could soften demand; unexpected large-scale Chinese capacity additions could temporarily push prices lower. For buyers consuming ≥20 MT/year, Q4 2025 annual contract locking (at seasonally lower prices) is the recommended risk management approach.
