Case Study: Bonded Air Freight of Oversized BLAST FREEZERS from Russia to Singapore

Case Study: Bonded Air Freight of Oversized BLAST FREEZERS from Russia to Singapore showcases how Tonlexing managed a highly sensitive shipment under strict handling requirements and a complex bonded transit route. In this case, two large blast freezers were shipped from Moscow to Singapore via Shenzhen, China — without being tilted, stacked, or cleared through Chinese customs. From oversized cargo space booking to bonded re-export and final delivery, this project demonstrates the power of precision logistics.

Project Background

In international logistics, not all cargo can be handled the same way. Certain products require special handling, precise routing, and zero tolerance for risk. This case involved shipping two oversized BLAST FREEZERS from Moscow, Russia (SVO) to Singapore (SIN) with bonded transit through Shenzhen, China (SZX) — a job requiring expert coordination and customized solutions.

The customer, a Russian manufacturer supplying commercial cold storage systems, had strict requirements:

• Door-to-door service

• Air freight using cargo aircraft

• No customs clearance in China

• Cargo must not be tilted or stacked under any circumstance

To meet these needs, we at Tonlexing designed and executed a bonded SVO–SZX–SIN routing with zero handling damage, on-time delivery, and full compliance with the cargo restrictions.

Cargo Description

• Packaging: Heavy-duty wooden crates with pallet base

• Nature: Precision cold storage equipment

• Value: High-value cargo, sensitive to shocks, pressure, or incorrect positioning

• Labeling: Each crate marked with “FRAGILE,” “DO NOT TILT,” and “DO NOT STACK”

These conditions made it unsuitable for commercial passenger flights or standard pallet-based operations. Every step required careful planning with freighter aircraft and non-consolidated handling.

Shipping Route: SVO – SZX – SIN

We recommended the following route for optimal control, speed, and safety:

• Step 1: Moscow (SVO) → Shenzhen (SZX)
  Wide-body cargo flight from Russia to China

• China: Bonded Transit at SZX 
  Cargo remains under customs seal, not cleared into China
  Transferred within bonded zone under supervision

• Step 2: Shenzhen (SZX) → Singapore (SIN)
  Direct cargo flight with proper booking for oversized non-stackable goods

• Final Delivery in Singapore
  Customs clearance + local delivery to client warehouse

Process Overview

Pickup in Moscow

• Our Russian partner arranged pickup with a tail-lift truck

• Forklift loading ensured safe transfer of the two crates

• Each unit was checked for external damage before transport

• Export documents and air waybill prepared in advance

Time: 1 day

Special Handling: Upright position at all times

Air Freight from Russia to Shenzhen

The cargo was loaded onto a dedicated wide-body freighter, selected for its ability to handle large and heavy shipments. It was positioned strictly in accordance with the client’s “NO STACK” instructions and secured with heavy-duty straps and padding to prevent any movement during transit. The airline confirmed the booking under a special cargo code (SCC: GEN + BIG) to ensure proper handling throughout the flight.

Flight time: Approx. 10 hours

Arrival: Shenzhen Airport, customs bonded zone

Bonded Transfer in Shenzhen (SZX)

This was the most critical leg of the journey.

• The cargo was not cleared into China, avoiding import taxes and paperwork delays

• Instead, our bonded warehouse partner facilitated a transfer under customs seal

• No unpacking, tilting, or repositioning took place — crates remained untouched

• A second airway bill was issued for the SIN leg

This bonded transit setup saved the client over $2,000 in potential import tax and handling costs
