Success Story: Transport of 22 Tons of PVC Additives to Moscow Using TIR High Sided Vehicles

Project Overview

In July 2025, DR Trans delivered 22 tons of UN 3267-classified PVC additives from Shandong to Moscow using high sided vehicle and TIR protocols. PVC additives refer to chemical substances added to improve the processing properties or final product performance of polyvinyl chloride (PVC) plastics. The cargo was secured with triple-layer protection: moisture-proof cloth covers, reinforced bulk bags, and polymer film wrapping. This approach enabled a 9-day transit with zero moisture damage or contamination.

Why  High Sided Vehicle Optimize Bagged Chemical Transport

Operational Insight: high sided vehicles’ adjustable side stakes permitted rapid tarp deployment during sudden weather changes – critical for moisture-sensitive additives.

TIR System: Accelerating Cross-Border Transit

As a TIR-certified operator, DR Trans leveraged this United Nations framework to overcome traditional border delays:

1. Single-Seal Clearance
   Chinese customs applied tamper-proof seals in Shandong, recognized by all transit countries.

2. Paperless Digital Management
   Real-time GPS coordinates synced with electronic TIR Carnet, providing:

   • Automated transit logs

   • Instant exception alerts

   • Client visibility via web portal

3. Eliminated Border Queues
   Kazakhstan and Russian border crossings are completed in under 2 hours each, compared to 12-36 hours for standard shipments.

Phase-by-Phase Operational Execution

Stage 1: Preparation in Shandong (Days 1-2)

• Packaging Protocol

  1. Primary: PVC additives sealed in UN-certified polypropylene bulk bags (1-ton capacity)

  2. Secondary: Polymer stretch film wrapping (6-layer UV-resistant)

  3. Tertiary: Waterproof canvas covers lashed over pallet stacks

• Loading Configuration

  • Removed side stakes for forklift loading

  • Stacked 48 pallets (4 layers high) with anti-slip mats between tiers

  • Secured with a cross-lashing system (rated 2,500kg)

Stage 2: Trans-Kazakhstan Transit (Days 3-5)

• Weather Protection

  • Deployed side-mounted tarps during precipitation near Astana

  • Maintained 10cm ventilation gaps to prevent condensation

• Vibration Control
  Rubber dampeners under pallets absorbed road shocks

Stage 3: Russian Final Delivery (Days 6-9)

• Moisture Integrity Check
  Humidity sensors confirmed 0% water ingress upon Moscow arrival

• Unloading Efficiency
  Removed side stakes for direct forklift transfer to the warehouse

Hazard-Specific Safety Engineering

1. Moisture & Contamination Prevention

2. Cargo Stability System

• Pallet Matrix: 4×3 configuration per trailer tier

• Anti-Shift Measures:

  • Corner protectors on all bulk bags

  • Cross-lashing at 45° angles

  • Edge-protector boards between layers

3. Regulatory Compliance

• Documentation:
  TIR Carnet specified "film-wrapped bulk bags" with UN certification codes

• Training:
  Drivers certified in tarp management for hazardous materials

 High Sided Vehicle Advantages for Bagged Chemicals

Results Achieved

• ✅ 9-day delivery through 3 countries

• ✅ Zero moisture damage despite 320km rainy transit

• ✅ 100% bag integrity – no rips/leaks

• ✅ 3-hour average border clearancea

Conclusion: Precision Packaging + Purpose-Built Equipment

This operation proved high sided vehicles are ideal for bagged chemical transport when combined with:

1. Adaptive protection (moisture-proof covers + film wrapping)

2. TIR efficiency (seamless border crossings)

3. Load engineering (scientific stacking/lashing)
