Success Story: Transport of 22 Tons of PVC Additives to Moscow Using TIR Stake Trailers

Project Overview

In July 2025, DR Trans delivered 22 tons of UN 3267-classified PVC additives from Shandong to Moscow using stake trailers and TIR protocols. 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 Stake Trailers Optimize Bagged Chemical Transport

Operational Insight: Stake trailers’ 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

Stake Trailer 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 stake trailers 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)
