Bitumen Price in Thailand Today
As of today, the benchmark price for penetration grade bitumen 60/70 in Thailand ranges from THB 25,800 to THB 28,400 per metric tonne (approximately USD 720–795/MT), depending on grade, packaging, and delivery terms. Imported cargoes from Singapore and South Korea land at around THB 26,500–29,000/MT CIF Bangkok, while domestic refinery supply from Thai Oil and IRPC trades at a discount of roughly THB 700–1,200/MT. Prices are updated weekly and typically move within a 2–4% band in either direction per month.
Current Bitumen Price Benchmarks in Thailand (2024–2025)
Thailand consumes roughly 1.8–2.2 million metric tonnes of bitumen annually, with peak demand between November and April (dry season road construction). The table below shows the latest reference prices across popular grades and packaging types.
| Bitumen Grade | Packaging | Price (THB/MT) | Price (USD/MT) | Change vs. Last Month |
|---|---|---|---|---|
| Penetration 60/70 | Bulk (tanker) | 25,800 – 27,500 | 720 – 770 | ▼ -1.8% |
| Penetration 60/70 | New steel drum | 27,200 – 28,900 | 760 – 810 | ▼ -1.2% |
| Penetration 80/100 | Bulk | 25,300 – 26,900 | 705 – 752 | ▼ -2.1% |
| Polymer Modified (PMB) | Bulk | 31,500 – 34,800 | 880 – 975 | ▲ +0.9% |
| Cutback MC-30 | Drum | 29,800 – 32,500 | 833 – 910 | ▲ +0.4% |
| Emulsion CSS-1h | Drum/IBC | 24,500 – 26,700 | 685 – 747 | ▼ -0.6% |
Key observations:
- Bulk vs. drummed pricing: Steel drum packaging adds THB 1,300–1,500/MT due to container and drum return costs, plus 2–4 weeks additional lead time.
- Import vs. domestic: Imported Singapore (Shell, PCS) cargoes carry a premium of THB 850–1,400/MT over domestic Thai refinery supply.
- FX sensitivity: With USD/THB hovering around 35.8–36.2, every THB 1.00 move in the exchange rate shifts import parity by roughly THB 720/MT.
- Volume discount: Orders above 500 MT typically attract THB 300–600/MT concession from traders.
For real-time landed cost calculations, buyers should benchmark against Singapore FOB (approx. USD 610–645/MT) plus freight of USD 25–38/MT to Laem Chabang or Bangkok.
What Drives Bitumen Prices in Thailand Today?
Bitumen pricing in Thailand is a function of crude oil benchmarks, import parity, refinery utilization, and construction season demand. Because Thailand imports roughly 55–60% of its bitumen from Singapore, South Korea, and the Middle East, global factors dominate local prices.
Bitumen is a heavy residue from crude distillation. When Brent crude moves above USD 85/barrel, Asian bitumen benchmarks typically rise within 7–14 days.
| Driver | Current Level | Impact on Thai Bitumen Price |
|---|---|---|
| Brent crude | USD 82–86/bbl | +THB 400–600/MT if sustained |
| Singapore bitumen FOB | USD 610–645/MT | Sets import floor for Thailand |
| USD/THB exchange rate | 35.8–36.2 | Weak baht raises landed cost |
| Thai diesel subsidy policy | Active | Indirect: affects transport cost |
Two Thai refiners dominate local supply:
- Thai Oil (Sriracha): ~500,000 MT/year bitumen capacity
- IRPC (Rayong): ~400,000 MT/year bitumen capacity
When either refinery schedules a turnaround (typically 3–5 weeks), spot prices in Thailand can spike THB 800–1,500/MT within days.
| Month | Demand Level | Price Tendency |
|---|---|---|
| Nov–Feb | Very high | ▲ +2–4% |
| Mar–Apr | High | ▲ +1–2% |
| May–Jul | Monsoon / low | ▼ -1–3% |
| Aug–Oct | Recovery | Stable |
Road construction under the Department of Highways (DOH) and Department of Rural Roads (DRR) typically accelerates budget disbursement in Q1 of the fiscal year (Oct–Jan), pushing bitumen demand up 15–25% quarter-on-quarter.
Thailand Bitumen Price vs. Regional Markets
Thailand is priced at a slight discount to Singapore and a premium to Malaysia, reflecting freight economics and local refining capacity.
| Market | P60/70 Bulk (USD/MT) | vs. Thailand |
|---|---|---|
| Thailand | 720 – 795 | Baseline |
| Singapore | 745 – 810 | +2–3% |
| Malaysia | 700 – 770 | -2–3% |
| Vietnam | 735 – 805 | +1–2% |
| Indonesia | 750 – 830 | +4–5% |
| South Korea (FOB) | 690 – 755 | -3–5% |
Takeaways:
- Thai buyers importing from South Korea can save USD 25–45/MT before freight, but lead time stretches to 18–25 days.
- Intra-ASEAN trade (Malaysia → Thailand) benefits from AFTA 0% tariff, making it competitive for southern Thai projects.
- Land border delivery (Songkhla, Sadao) adds THB 400–700/MT for logistics but avoids port congestion at Laem Chabang.
How Thai Bitumen Prices Are Quoted Today
Understanding the quotation structure helps buyers compare apples to apples.
- Ex-refinery (EXW Rayong/Sriracha): Lowest headline price, buyer arranges trucking. Typically THB 25,300–26,800/MT.
- CIF Bangkok/Laem Chabang: Includes ocean freight and insurance. THB 26,500–29,000/MT.
- DAP job site (upcountry): Adds trucking of THB 600–1,800/MT depending on distance from Rayong. For Chiang Mai delivery, add THB 1,500–2,000/MT.
- Drummed (delivered): Highest cost, usually THB 28,500–31,000/MT, driven by drum cost and handling.
- LC at sight for imports (importers use Bangkok Bank, Kasikorn)
- 30-day credit common for domestic refiners to established contractors
- Performance bond of 5–10% typical for orders over 1,000 MT
| Order Volume | Typical Discount vs. List |
|---|---|
| < 100 MT | 0% (list price) |
| 100 – 500 MT | THB 150–300/MT |
| 500 – 2,000 MT | THB 300–600/MT |
| > 2,000 MT | THB 600–900/MT (negotiated) |
Outlook: Where Are Thai Bitumen Prices Heading?
Three signals suggest Thai bitumen prices will remain range-bound to slightly softer over the next 30–60 days:
1. Monsoon tail-off: October–November rain in Thailand historically suppresses construction, keeping demand 10–15% below peak.
2. Crude strength: If Brent holds above USD 85/bbl, expect +THB 400–600/MT upside risk.
3. Baht weakness: A move from THB 36.0 to THB 37.0 per USD would add roughly THB 700/MT to landed import costs — the single biggest swing factor for Thai buyers right now.
Forecast (next 30 days):
- Base case (60% probability): THB 25,500–28,000/MT
- Bull case (25%): THB 26,500–29,200/MT (crude spike + baht weakness)
- Bear case (15%): THB 24,800–27,000/MT (weak demand + crude correction)
Frequently Asked Questions
Q1: What is the current bitumen price in Thailand today?
As of today, penetration grade bitumen 60/70 in Thailand trades between THB 25,800 and THB 28,400 per metric tonne (roughly USD 720–795/MT). Bulk ex-refinery supply at Rayong sits at the lower end, while drummed CIF deliveries to Bangkok sit at the higher end. Prices are typically updated weekly by Thai Oil, IRPC, and major importers.
Q2: Is bitumen cheaper to buy domestically in Thailand or import it?
Domestic Thai refinery supply is generally THB 700–1,200/MT cheaper than imported cargoes, because it avoids freight, duty, and port handling. However, during refinery turnarounds — typically 3–5 weeks per year — imported Singapore or Korean bitumen becomes the only available source, closing the price gap entirely. Buyers should always compare landed CIF cost against ex-refinery quotes.
Q3: How much does bitumen price fluctuate in Thailand per month?
Thai bitumen prices typically move 2–4% per month, equivalent to THB 500–1,200/MT. The biggest single-day moves (up to THB 800/MT) occur when Brent crude spikes over USD 5/barrel in a week, or when the Thai baht moves more than 1% against the USD.
Q4: What is the cheapest bitumen grade available in Thailand?
Penetration grade 80/100 is generally the cheapest at THB 25,300–26,900/MT bulk, about THB 400–600/MT below 60/70. It is suitable for warmer climates and lower-traffic roads. Bitumen emulsion CSS-1h in drums is also competitively priced at THB 24,500–26,700/MT but requires different application equipment.
Q5: How does the Thai baht exchange rate affect bitumen prices?
Thailand imports roughly 55–60% of its bitumen, so the USD/THB rate is a major price driver. Every THB 1.00 depreciation against the USD adds approximately THB 700–750/MT to imported bitumen landed cost. Conversely, a stronger baht (below 35.5) can pull prices down by a similar amount within 1–2 weeks.
