How to choose the appropriate transportation method?

It is recommended to conduct comprehensive evaluation based on shipment volume and destination:

• Maritime Transportation: Ocean 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)
• Highway: Rail transport: Cross-border transportation requires special ADR agreement permits

In addition to regular trade documents, the following must be prepared:

• Hazard classification identification report (issued by CNAS accredited laboratory)
• Cylinder periodic inspection certificate (with electronic chip traceability information)
• Pollution emergency plan (as required by MARPOL Annex III)

How to handle transportation accidents?

According toERG2024 Emergency Response Guidebookrecommends implementing three-level response:

1. Immediately activate the vehicle emergency inhibition system (EIS)
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)

What Changes Are Expected in International Transport Insurance Rates for 2025?

Affected by global climate anomalies, hazardous chemical transport premiums show:

• Marine insurance: base rate increase of 15% (Lloyds January, 2025 data)
• Land transport insurance: new extreme weather surcharge (premium rate 0.8%-1.2%)
• It is recommended to take out insurancePreventive rescue cost insurance(Can cover 80% of emergency handling costs)
