CSS-1h bitumen emulsion price ranges from $390 to $520 per metric ton FOB in 2024–2025, depending on base asphalt grade (60/70 or 80/100 penetration), residual binder content (typically 57–63%), and order volume. For a standard 20 MT FCL shipment with 60% residue, expect $430–$470/MT FOB Houston or Jebel Ali. Bulk vessel orders above 500 MT typically unlock a 7–12% discount, dropping effective pricing to $395–$430/MT.
What Determines CSS-1h Bitumen Emulsion Price?
CSS-1h (Cationic Slow-Setting, Grade 1 hard residue) is priced as a function of three cost layers: base asphalt cost (65–75% of total), emulsifier and additive chemistry (8–12%), and processing, packaging, and logistics (15–25%).
Unlike penetration-grade bitumen quoted in fixed market indices, CSS-1h has no single global benchmark. Pricing is derived from the parent asphalt index (e.g., Singapore 60/70 or Iran 60/70), then adjusted for emulsification loss.
Cost breakdown per MT of CSS-1h emulsion (typical):
| Cost Component | Share of Total | Example Value (USD/MT) |
|---|---|---|
| Base asphalt (60/70 pen) | 68% | $300 |
| Emulsifier (cationic, slow-set) | 10% | $44 |
| Water + HCl + stabilizers | 4% | $18 |
| Processing / colloid mill energy | 5% | $22 |
| Packaging (drums/IBCs) | 6% | $26 |
| Freight + FOB margin | 7% | $31 |
| Total FOB | 100% | ~$441 |
Because CSS-1h contains 38–43% water, buyers pay for a diluted product. The residual asphalt content (RAC) is the single most important price lever — every 1% increase in RAC raises the price by roughly $7–9/MT at current asphalt costs.
Quick rule of thumb: CSS-1h price ≈ (base asphalt price per MT × residue %) + fixed conversion cost of $120–160/MT.
CSS-1h Price Comparison by Origin and Residue Content
The table below compares FOB pricing across major supply hubs. Values reflect Q4 2024–Q1 2025 averages for 20–100 MT lots.
| Origin | Base Asphalt Grade | Residue Content | Price FOB (USD/MT) | Min. Order |
|---|---|---|---|---|
| USA (Gulf Coast) | 60/70 | 60% | $455–$495 | 20 MT |
| UAE (Jebel Ali) | 60/70 | 60% | $420–$460 | 20 MT |
| Iran (Bandar Abbas) | 60/70 | 60% | $390–$430 | 100 MT |
| Malaysia (Port Klang) | 80/100 | 57% | $400–$440 | 20 MT |
| China (Shanghai) | 60/70 | 62% | $430–$465 | 20 MT |
| Spain (Barcelona) | 50/70 | 60% | $470–$510 | 20 MT |
Key observations:
- Iranian and Malaysian supply offer the lowest FOB entry points, but sanctions/logistics risk adds $25–$60/MT in effective landed cost.
- USA and EU product commands a 10–18% premium due to AASHTO M208 / EN 13808 compliance documentation.
- Higher residue (62–63%) formulations are increasingly preferred because they cut freight cost per unit of active binder by 5–8%.
| Line Item | Cost (USD) |
|---|---|
| Emulsion FOB | $440/MT × 20 = $8,800 |
| Ocean freight + THC | $900 |
| Insurance (0.4%) | $39 |
| Customs + documentation | $180 |
| Landed total | $9,919 ($496/MT) |
CSS-1h vs Other Bitumen Emulsions: Price and Application Comparison
CSS-1h competes directly with SS-1h, CRS-2, and CSS-1 in the slow-setting cationic category. Price differences reflect residue hardness and set speed.
| Product | Set Speed | Typical Residue | Price Range (USD/MT FOB) | Primary Use |
|---|---|---|---|---|
| CSS-1h | Slow | 57–63% | $390–$520 | Tack coats, fog seals, slurry |
| CSS-1 | Slow | 57–60% | $380–$500 | Tack, dust control |
| SS-1h | Slow (anionic) | 57% | $370–$490 | Cold recycling |
| CRS-2 | Rapid | 65–67% | $430–$560 | Chip seal, prime |
| CRS-2P | Rapid | 65–67% | $450–$580 | Polymer-modified chip seal |
Why CSS-1h costs more than CSS-1 in most markets: the "h" designation requires a harder residual binder (penetration ≤ 100 dmm at 25°C), which limits the base asphalt selection to premium 60/70 grades rather than softer 80/100 or 150/200 feedstocks. That grade constraint adds $15–30/MT.
Why CSS-1h costs less than CRS-2: higher water content (40% vs. 34%) and lower emulsifier loading. However, CRS-2 delivers more active binder per ton, so cost per unit of residual asphalt often favors rapid-set grades for high-volume chip seal projects.
What Drives CSS-1h Price Volatility?
CSS-1h tracks base asphalt with a 0.6–0.75 beta — meaning a 10% rise in 60/70 penetration-grade bitumen produces a 6–7.5% increase in emulsion price, dampened by the fixed conversion cost.
Volatility drivers ranked by impact:
- Base asphalt index (Singapore/Iran 60/70): 65–75% of price variance. A $50/MT swing in base asphalt = $30–38/MT swing in CSS-1h.
- Emulsifier (tallow amine) prices: 8–12% impact. Tallow-derived cationic emulsifiers spiked 22% in 2022 and remain 15% above 2019 levels.
- Seasonality: Q2–Q3 (construction season) pricing runs 4–7% above Q4–Q1. Winter procurement in November–January captures the lowest annual quotes.
- Freight and container availability: Red Sea diversions added $400–$900 per 20' container to Europe-bound routes in 2024.
- Currency: Products priced in USD expose buyers in EUR, INR, and NGN to 5–12% effective cost swings.
| Year | Avg Price (USD/MT) | YoY Change |
|---|---|---|
| 2020 | $310 | — |
| 2021 | $365 | +17.7% |
| 2022 | $505 | +38.4% |
| 2023 | $470 | −6.9% |
| 2024 | $435 | −7.4% |
| 2025 (est.) | $420–$460 | −1% to +5% |
The 2022 spike reflected post-COVID asphalt tightness; the 2023–2024 correction reflects improved refinery output and softer Chinese demand.
How to Buy CSS-1h at the Best Price
Actionable procurement levers, ranked by savings potential:
1. Increase order volume to 100+ MT. Bulk drum or IBC orders cut per-unit packaging cost by $18–28/MT versus 20 MT lots.
2. Buy in Q4/Q1. Off-season procurement saves 5–8% versus peak-season quotes.
3. Specify 62–63% residue. Higher RAC reduces freight cost per active binder unit by 5–8%, even though headline $/MT rises.
4. Negotiate CIF, not FOB, for first orders. Landed-cost transparency prevents hidden port charges of $80–$150/MT.
5. Lock 6-month forward contracts. Fixed pricing removes volatility risk; suppliers typically accept a 2–4% premium over spot for this certainty.
6. Consider bulk vessel (5,000+ MT) for terminal projects. Vessel-parcel pricing can reach $360–$390/MT CFR for large infrastructure programs.
Red flags in low quotes:
- Prices below $350/MT FOB usually indicate diluted residue (<55%), recycled asphalt content, or non-compliant emulsifier systems.
- Missing AASHTO M208 / ASTM D2397 certification means the product may fail residue and sieve tests on delivery.
- Payment terms demanding 100% T/T upfront from unknown suppliers — use LC at sight or escrow for first transactions.
FAQ: CSS-1h Bitumen Emulsion Price
Q1: What is the current price of CSS-1h bitumen emulsion per ton?
CSS-1h currently trades at $390–$520 per metric ton FOB, with the most common 60% residue specification landing at $430–$470/MT. Prices vary by origin: Iranian and Malaysian supply is cheapest, while US and EU product carries a 10–18% premium.
Q2: Why is CSS-1h more expensive than penetration-grade bitumen?
Base 60/70 bitumen costs roughly $300–$350/MT, while CSS-1h costs $430–$470/MT because it includes $120–$160/MT in emulsifier, processing, water, and packaging costs. Buyers also pay for 38–43% water content, so cost per unit of active asphalt is higher.
Q3: How much does a 20 MT container of CSS-1h cost delivered?
A 20 MT FCL of CSS-1h from Jebel Ali to Rotterdam lands at approximately $9,900–$10,400 total ($495–$520/MT) including freight, insurance, and customs. US Gulf Coast to Europe routes run $50–$80/MT higher due to longer ocean transit.
Q4: Does residue content affect CSS-1h price?
Yes — every 1% increase in residue content raises CSS-1h price by $7–9/MT. A 63% residue formulation costs roughly $25–$30/MT more than a 60% version, but reduces freight cost per unit of active binder, often making it cheaper in landed terms.
Q5: What is the cheapest season to buy CSS-1h?
November through February is the cheapest procurement window, with prices running 4–7% below peak-season (May–August) quotes. Buyers who lock forward contracts in Q4 for spring delivery typically save $20–$35/MT versus spot purchases.
