Bulk Rock Salt for Deicing — EU vs US vs Nordic vs CIS Grades Compared
If you're sourcing bulk Egyptian rock salt for deicing, the first question is: which regional spec do you need to match?
This guide compares the five major international standards we ship to — EN 16811-1, ASTM D632, BS 3247, SS-EN 16811-1 (Nordic), and GOST 13830 (CIS) — with side-by-side spec tables, particle-size analysis, and indicative FOB pricing.
| Spec | Region | Min NaCl | Max moisture | Particle size | Anti-caking |
|---|---|---|---|---|---|
| EN 16811-1 Grade A | EU motorway | 97% | 1.5% (kiln) | 0/2 / 0/4 / 0/6.3 mm | E535 (or Type 2 free) |
| EN 16811-1 Grade B | EU high-speed | 97% | 1.5% | 2/8 mm | E535 |
| EN 16811-1 Grade C | EU stockpile/lump | 97% | 1.5% | 10-40 mm lump | n/a |
| EN 16811-1 Type 2 | EU (Med / S Europe) | 97% | 3-4% natural | varies | Free |
| BS 3247:2011 | UK + Ireland | 97% | 1.5% | 1.0-6.0 mm | E535 |
| ASTM D632 Grade 1 | US + Canada | 97% | 1.5% | 4.75-9.5 mm | E535 |
| ASTM D632 Grade 2 | US + Canada | 97% | 1.5% | 2.0-4.75 mm Fine | E535 |
| AASHTO M-143 | US/state DOT | 97% | 1.5% | (per ASTM D632) | E535 |
| SS-EN 16811-1 | Nordic | 97% | 1.5% | 0.5-8 mm | Pre-wetting compatible |
| GOST 13830 Grade I | CIS | 97% | 1.5% | 0.5-5 mm | Free |
| GOST 13830 Grade II | CIS bulk | 95% | 1.5% | 1.2-10 mm | Free |
Particle size is the biggest driver of regional preference. EU + UK favour finer fractions (0/6.3 mm motorway, 1.0-6.0 mm UK Highway) because European spreaders + winter-traffic densities call for fast melt + dispersed coverage. US + Canada use coarser fractions (4.75-9.5 mm Grade 1) because state DOT spreaders are calibrated for higher application rates per lane-mile + larger crystals slow melt extends ice-prevention duration.
Anti-caking — required (E535 sodium ferrocyanide ≤80 ppm) by most major standards, BANNED by Germany Bundesländer and parts of Switzerland and France on environmental grounds. EN 16811-1 distinguishes "Type 1" (with E535) from "Type 2" (without). If your tender forbids ferrocyanide, specify Type 2 or our pre-wetted variants which use NaCl/MgCl₂ brine instead.
Moisture — Type 2 EU sea salt at 3-4% moisture is significantly cheaper than kiln-dried (typically 25-40% lower FOB) because we skip the kiln-drying step. Buyers with covered depot storage and an immediate-application workflow can accept Type 2 without performance penalty.
We carry both. The buying decision is mostly:
Choose Bulk Egyptian Rock Salt for Deicing if:
- Your stockpile is uncovered (rock salt's low natural moisture handles rain better)
- You're in a continental climate (CIS, Eastern Europe, Nordic)
- You need maximum freight efficiency per dry tonne
- You want lump/coarse fractions for slow-melt pre-treatment
Choose Bulk Egyptian Sea Salt for Deicing if:
- You're in a maritime climate (UK, France, Spain, Italy)
- Type 2 natural-moisture (3-4%) is acceptable for cost savings
- You want fast-melt fine fractions (0/2 mm or 2.0-4.75 mm)
- Carbon footprint is a tender criterion (solar evaporation = near-zero embodied CO₂)
For pre-treatment fleets working at -10°C to -20°C, we ship pre-wetted product:
Compatible with all major spreader OEMs (Schmidt, Epoke, Falköping, Henke). See Pre-Wetted Sea Salt and Pre-Wetted Rock Salt SKUs.
| Grade | Range | Notes |
|---|---|---|
| EN 16811-1 Grade A kiln-dried | 65-85 | Sea or rock |
| EN 16811-1 Type 2 natural | 45-60 | Sea, 3-4% moisture, premium discount |
| BS 3247 UK Highway | 65-85 | Sea or rock |
| ASTM D632 Grade 1 | 70-90 | Sea or rock, longer freight to N America |
| GOST 13830 Grade I | 60-80 | Sea or rock, CIS preference |
| GOST 13830 Grade II | 45-60 | Bulk-grade, secondary processing |
| Pre-wetted | 75-100 | Premium for treated product |
