• Maritime TransportationOcean shipping: Suitable for large-volume transportation (single container loading ≥20 tons)
  • Advantage: Low unit cost (average price of Asia-Europe route in 2025 is $1200/TEU)
  • Risk: Need to prevent pressure increase caused by summer high temperatures
• Railway:China-Europe Railway ExpressNew dedicated chemical trains (transit time 18-22 days)
• HighwayRail transport: Cross-border transportation requires special ADR agreement permits

How to handle transportation accidents?

According toERG2024 Emergency Response Guidebookrecommends implementing three-level response:

2. Establish a 500-meter isolation zone (use pH test strips to monitor leakage range)
3. Contact local environmental authorities for neutralization treatment (acetic acid solution recommended)

How to Avoid Common Shipping Disputes?

Based on international arbitration cases from the past three years, special attention should be paid to:

• Temperature control clauses (recommended ±3℃ fluctuation range)
• Demurrage calculation methods (some ports have implemented tiered rates)
• Cargo purity guarantees (requiring third-party inspection agencies to take samples before loading)
