Blown asphalt (oxidized bitumen) from Kazakhstan is supplied at $410–$560 per metric ton FOB Aktau as of Q1 2025, with grades covering 85/25, 90/40, 95/25, 105/35, and 115/15 penetration ranges. Kazakhstan produces approximately 180,000–220,000 tons of oxidized bitumen annually, with roughly 60–65% exported to Uzbekistan, Russia, China, and Caspian-adjacent markets. Typical lead time from confirmed order to loading at Aktau Port is 12–18 days, depending on grade and volume.
What Is Blown Asphalt and Why Kazakhstan Matters
Blown asphalt — also called oxidized bitumen, industrial asphalt, or air-blown bitumen — is produced by passing air through hot petroleum residue (typically vacuum residue or short residue) at 240–280°C for 4–12 hours. The oxidation process increases the asphalt's softening point, viscosity, and hardness while reducing penetration value. The result is a material with distinct properties suited to roofing, waterproofing, pipe coating, and industrial applications — not road paving.
Kazakhstan has become a significant blown asphalt producer for three structural reasons:
- Feedstock availability: Three major refineries (Atyrau, Pavlodar, Shymkent) generate heavy vacuum residue with high asphaltene content — ideal for oxidation.
- Cost position: Kazakh oxidized bitumen undercuts European and Middle Eastern equivalents by 8–15% per ton at equivalent specification.
- Caspian logistics: Aktau and Kuryk ports provide direct maritime access to Iran, Azerbaijan, and onward to Turkey and the Mediterranean.
| Producer / Region | Annual Capacity (tons) | Primary Grades | Export Share |
|---|---|---|---|
| Atyrau Refinery complex | 85,000–100,000 | 85/25, 90/40, 95/25 | 65% |
| Pavlodar petrochemical | 40,000–50,000 | 90/40, 105/35 | 55% |
| Shymkent refinery | 30,000–40,000 | 85/25, 95/25 | 50% |
| Independent blenders | 25,000–30,000 | 105/35, 115/15 | 70% |
| Total | 180,000–220,000 | — | 60–65% |
The independent blenders segment has grown ~22% year-on-year since 2022, driven by export demand from Uzbekistan's roofing sector and Chinese waterproofing membrane manufacturers.
Blown Asphalt Grades Available in Kazakhstan: Specifications and Pricing
Kazakh producers supply blown asphalt in five standard penetration grades, aligned with GOST 9548-74 and increasingly with ASTM D312 equivalency. Below is the current specification and pricing matrix.
| Grade | Penetration (25°C, 0.1mm) | Softening Point (°C) | FOB Aktau Price ($/ton) | Typical Application |
|---|---|---|---|---|
| 85/25 | 21–29 | 85–90 | $510–560 | Roofing felt, shingles |
| 90/40 | 35–45 | 90–95 | $470–510 | Waterproofing membranes |
| 95/25 | 21–29 | 95–100 | $490–530 | Pipe coating, mastics |
| 105/35 | 30–40 | 105–110 | $445–485 | Industrial coatings, batteries |
| 115/15 | 10–20 | 115–120 | $490–540 | High-temp insulation, specialty |
Key specification notes:
- Solubility in toluene: minimum 99.0% for all export grades
- Flash point: minimum 230°C (open cup), critical for sea freight classification
- Penetration index: typically +2 to +4 (highly oxidized, low thermal susceptibility)
- Ash content: max 0.8–1.2% depending on grade
- Packaging options: bulk in bitutankers, 150 kg steel drums, 1-ton jumbo bags, or 25 kg polybags
The price spread between grades reflects production complexity, not just softening point. Grade 115/15 commands a premium because oxidation time extends to 10–12 hours, reducing throughput per reactor cycle by approximately 35%.
| Origin | 90/40 Price ($/ton) | Lead Time (days) | Min. Order (tons) |
|---|---|---|---|
| Kazakhstan (Aktau) | $470–510 | 12–18 | 100 |
| Iran (Bandar Abbas) | $490–525 | 20–30 | 200 |
| UAE (Fujairah) | $535–575 | 25–35 | 500 |
| Turkey (Izmir) | $520–560 | 15–25 | 200 |
| China (domestic FOB) | $495–540 | 10–20 | 300 |
| Russia (Novorossiysk) | $475–520 | 18–28 | 150 |
Kazakhstan's advantage is structural: feedstock cost is 12–18% lower than Gulf producers, and Aktau Port charges $18–24 per ton for handling and berthing versus $35–45 at Fujairah.

Quality Standards and Certifications for Kazakh Blown Asphalt
Kazakh blown asphalt exports comply with multiple international standards, depending on destination and application. Understanding the certification landscape prevents customs delays and quality disputes.
| Standard | Region | Key Parameters |
|---|---|---|
| GOST 9548-74 | CIS, Russia, Central Asia | Penetration, softening point, solubility |
| ASTM D312 | USA, global | Type I–IV classification by softening point |
| EN 13370 | EU | Oxidized bitumen for industrial use |
| IS 702 | India | Blown asphalt specification |
- Certificate of Origin (CT-1 form for CIS preferences)
- Certificate of Analysis (producer + optional third-party)
- Material Safety Data Sheet (MSDS) — mandatory for sea freight
- Packing List and Commercial Invoice
- Bill of Lading / CMR / Rail Waybill
- Phytosanitary certificate (only if wooden pallets used)
Critical compliance note: Blown asphalt with flash point below 230°C is classified as UN 1999 Class 3 flammable liquid for sea transport, requiring special stowage and adding $15–25 per ton to freight cost. All major Kazakh producers now guarantee 230°C+ flash point for export grades.
Independent blenders (approximately 15–20% of total Kazakh output) show higher batch-to-batch variation. Penetration values may vary by ±8% versus ±3% for refinery-produced material. For critical applications — pipe coating, high-temp insulation — specify refinery-origin material and require third-party inspection.
Market Outlook: Kazakhstan Blown Asphalt 2025–2027
Three factors will shape Kazakh blown asphalt supply and pricing through 2027:
1. Feedstock competition from road bitumen
Kazakh refineries face rising domestic demand for paving-grade bitumen (grades 50/70, 70/100) for road construction programs. Government infrastructure spending increased 18% in 2024, diverting vacuum residue from oxidation to straight-run production. This could reduce blown asphalt output by 5–8% annually through 2026 unless new oxidation capacity comes online.
2. Chinese and Uzbek demand growth
- Uzbekistan: roofing material production grew 26% in 2024; blown asphalt imports from Kazakhstan rose to ~48,000 tons
- China: waterproofing membrane manufacturers in Xinjiang and Gansu provinces increased Kazakh imports by 31% year-on-year
- Turkey: post-earthquake reconstruction drives waterproofing demand; Kazakh material gaining share against Iranian supply
3. Logistics infrastructure upgrades
- Aktau Port expansion (Phase 2, completion 2026) will add 1.2 million tons annual dry cargo capacity, reducing berthing delays
- Trans-Caspian International Transport Route (TITR) improvements cut transit time to Turkey by 3–5 days
- New rail link Atyrau–Makat double-tracking reduces inland transport cost by an estimated $8–12 per ton
| Grade | Q1 2025 (actual) | Q4 2025 (forecast) | Q4 2026 (forecast) |
|---|---|---|---|
| 85/25 | $510–560 | $520–575 | $535–590 |
| 90/40 | $470–510 | $480–525 | $495–540 |
| 95/25 | $490–530 | $500–545 | $515–560 |
| 105/35 | $445–485 | $455–500 | $470–515 |
| 115/15 | $490–540 | $505–560 | $520–575 |
Forecast assumes Brent crude averaging $75–85/bbl and no major refinery disruptions. A Brent price above $95/bbl would push all grades up by $35–50 per ton.
