Bitumen Price in Bangkok
Last updated: 2026-10-01
Bitumen Price in Bangkok
As of Q1 2025, the average bitumen price in Bangkok is THB 19,800–21,500 per metric ton (USD 545–595/ton) for 60/70 penetration-grade bitumen in bulk (tanker load), while drummed bitumen (new steel drums) trades at THB 22,000–23,800 per metric ton (USD 610–660/ton). Prices fluctuate weekly, driven primarily by Singapore and Middle East refinery FOB benchmarks, THB/USD exchange rates, and domestic logistics costs — with a typical spread of ±4–6% between quoted and settled prices. Spot buyers ordering under 100 tons can expect to pay a THB 500–900/ton premium, while annual contract holders of 5,000+ tons often secure 3–7% below the listed market rate.
What Determines Bitumen Price in Bangkok?
Bangkok is Thailand's largest bitumen consumption hub, absorbing roughly 1.8–2.2 million tons annually for road construction, roofing, and waterproofing. Because Thailand imports about 65–70% of its bitumen (mainly from Singapore, South Korea, Bahrain, and the UAE), local pricing is a passthrough of import economics.
The price formula most Thai traders use is:
Bangkok price = FOB origin + freight + import duty + VAT 7% + inland logistics + trader margin
| Cost Component | Typical Range (THB/ton) | Share of Final Price |
|---|---|---|
| FOB Singapore (60/70 pen) | 14,500–15,800 | ~72–75% |
| Ocean freight + insurance | 900–1,400 | ~5–7% |
| Import duty & customs | 0–500 (varies by FTA) | 0–2.5% |
| VAT 7% | ~1,300–1,500 | ~7% |
| Inland logistics (port → Bangkok) | 400–700 | ~2–3% |
| Trader margin | 600–1,200 | ~3–6% |
Key drivers to monitor:
- Singapore FOB benchmark — the single biggest lever; a USD 20/ton move shifts Bangkok prices by roughly THB 700/ton.
- THB/USD exchange rate — every 1 THB strengthening against the USD reduces landed cost by ~1.5–2%.
- Crude oil (Brent) — bitumen is a heavy-end refinery product; a USD 5/bbl Brent move typically translates to USD 10–15/ton on bitumen within 2–4 weeks.
- Seasonality — demand peaks in the dry season (November–April) for road paving, pushing prices up 2–5%; the rainy season (May–October) softens them.
- Thai government infrastructure budget — Department of Highways and Expressway Authority tenders can absorb 300,000–500,000 tons in a single quarter, tightening supply.
Bitumen Price in Bangkok by Grade (2025)
Different grades command different prices. Penetration grades dominate Thai road work, while polymer-modified bitumen (PMB) is increasingly used on expressways and airports.
| Grade | Packaging | Price Range (THB/ton) | Price Range (USD/ton) |
|---|---|---|---|
| 60/70 pen | Bulk tanker | 19,800–21,500 | 545–595 |
| 40/50 pen | Bulk tanker | 20,500–22,200 | 565–615 |
| 80/100 pen | Bulk tanker | 19,500–21,000 | 535–580 |
| 60/70 pen | New steel drum | 22,000–23,800 | 610–660 |
| PMB 60 (SBS-modified) | Bulk tanker | 24,500–27,000 | 680–750 |
| Cutback / emulsified | Drum/IBC | 23,000–26,500 | 635–735 |
Prices are ex-Bangkok (Bang Sue, Bang Na, or Laem Chabang delivery), excluding VAT unless stated. Bulk buyers typically settle on a 15–30 day credit term.
Notable patterns:
- Drummed bitumen carries a THB 2,200–2,500/ton premium over bulk due to drum cost, handling, and lower volume efficiency.
- PMB commands a 20–28% premium — justified by SBS polymer content (3–5% by weight) and higher mixing temperatures.
- 40/50 pen is 3–4% costlier than 60/70 because of tighter refinery yield.
Bangkok vs Regional Bitumen Prices
Bangkok is generally mid-priced in Southeast Asia — cheaper than Vietnam and the Philippines (which carry higher logistics costs) but slightly more expensive than Singapore (the refining source).
| City / Market | 60/70 Pen Bulk (USD/ton) | vs Bangkok |
|---|---|---|
| Bangkok, Thailand | 545–595 | Baseline |
| Singapore | 505–545 | −7% to −9% |
| Ho Chi Minh City, Vietnam | 560–620 | +3% to +5% |
| Manila, Philippines | 590–650 | +8% to +10% |
| Jakarta, Indonesia | 555–610 | +2% to +3% |
| Kuala Lumpur, Malaysia | 530–580 | −3% to −5% |
Why the gap?
- Singapore benefits from zero freight — it's the refinery origin.
- Vietnam and the Philippines pay more for inland distribution and, in some cases, face longer port dwell times (7–12 days vs. 3–5 days at Laem Chabang).
- Malaysia enjoys favorable supply from Port Klang and regional trade agreements.
- Thailand sits in the middle: proximity to Singapore refineries, efficient Laem Chabang port, but 7% VAT and fuel excise pass-throughs.
How to Get the Best Bitumen Price in Bangkok
Buyers can realistically save 5–12% on annual procurement by applying structured sourcing tactics.
- Buy in bulk tankers, not drums — saves THB 2,200–2,500/ton immediately.
- Time purchases to the rainy season (May–October) — prices dip 2–5% as paving demand slows.
- Lock annual contracts — 5,000+ ton commitments typically secure 3–7% discounts and priority allocation during peak season.
- Leverage FTA routes — ASEAN Trade in Goods Agreement (ATIGA) imports from Singapore/Malaysia can reduce duty to 0%.
- Hedge currency exposure — forward contracts on THB/USD protect against 1.5–3% swings in landed cost.
- Consolidate freight — co-loading with other Bangkok buyers can cut ocean freight by 15–20%.
- Compare 3–4 traders minimum — quoted spreads for identical specs commonly reach THB 800–1,200/ton.
- Buy off-spec or "rebate" bitumen for non-critical applications — savings of 8–15% but with quality verification required.
A realistic procurement calendar for a mid-sized Bangkok contractor using 2,000 tons/year:
| Quarter | Action | Expected Price Position |
|---|---|---|
| Q1 | Tender-based buying (dry season) | Peak, +3–5% |
| Q2 | Negotiate annual contract | Mid, flat |
| Q3 | Opportunistic spot buys (rainy) | Trough, −2–5% |
| Q4 | Pre-buy for next paving season | Rising, +1–3% |
Cost Calculator: Estimate Your Bangkok Bitumen Spend
Rather than tracking daily price bulletins, most buyers benefit from a total-cost model that captures freight, duty, VAT, and storage. A 1,000-ton order at THB 20,500/ton bulk, for example, breaks down as:
- Base product: THB 20,500,000
- VAT 7%: THB 1,435,000
- Inland trucking (25 × 40 tons): THB 550,000
- Storage (30 days): THB 180,000
- Total landed: THB 22,665,000 (THB 22,665/ton)
That's a 10.6% uplift over the quoted ex-works price — a gap many first-time buyers underestimate. Running these numbers before negotiating gives you a defensible target price and reveals which line items have the most leverage (usually inland logistics and storage, not the bitumen itself).

FAQ: Bitumen Price in Bangkok
Q1: What is the current price of bitumen in Bangkok?
As of Q1 2025, 60/70 penetration bitumen in Bangkok costs THB 19,800–21,500 per ton (USD 545–595/ton) in bulk tanker loads, and THB 22,000–23,800 per ton (USD 610–660/ton) in new steel drums. Prices update weekly based on Singapore FOB benchmarks and THB/USD rates.
Q2: Why is bitumen more expensive in Bangkok than Singapore?
Bangkok imports the majority of its bitumen from Singapore refineries, adding ocean freight (THB 900–1,400/ton), 7% VAT, and inland logistics. These layers create a 7–9% price gap versus Singapore FOB, even before trader margin.
Q3: What is the cheapest way to buy bitumen in Bangkok?
The lowest-cost route is bulk tanker purchase on an annual contract (5,000+ tons), ideally timed to the rainy season (May–October). This combination can save 8–12% versus spot drum purchases during peak dry-season demand.
Q4: How much does PMB (polymer-modified bitumen) cost in Bangkok?
SBS-modified PMB 60 in Bangkok trades at THB 24,500–27,000 per ton (USD 680–750/ton) in bulk — a 20–28% premium over standard 60/70 penetration grade, reflecting 3–5% SBS polymer content and higher processing temperatures.
Q5: How often do bitumen prices change in Bangkok?
Most Bangkok traders revise quotes weekly, with major adjustments following Singapore FOB movements. Spot prices can shift ±2–4% within a month, while contract prices are usually fixed for quarterly or semi-annual periods.
