In the rapidly evolving freight forwarding and logistics industry, the abundance and diversity of specialized terminology can often leave professionals scratching their heads. Behind each seemingly simple term lies complex regulations and industry practices that become particularly crucial when navigating new policies and regulations.
A recent notice from trailer companies has sparked intense discussion within the industry about terms like "single drop," "single haul," "double haul," and "double back." What do these terms actually mean, and why are these regulations being adjusted in response to policy changes?
The New Regulations Explained
First, let's examine the notice issued by trailer companies regarding new transportation regulations, which outlines different handling methods for standard containers (20-foot) and large containers (40-foot):
- For standard containers (20-foot): If the cargo weight exceeds 10 tons, the "single drop" method will be implemented, eliminating shared container arrangements.
- For large containers (40-foot): Trailers will not accept any container exceeding 25 tons in total weight.
- 40HQ containers (40-foot high cube): Transportation services will be temporarily suspended with no specified resumption date.
These new rules clearly prioritize safety and regulatory compliance. The "single drop" requirement for overweight standard containers aims to mitigate potential transportation risks. But what exactly does "single drop" mean, and how does it differ from other common industry terms?
Key Terminology Breakdown
1) Single Haul: This term refers to a trailer transporting only one container at a time, typically a 20-foot standard container. This method reduces overloading risks and simplifies loading/unloading processes while requiring less technical skill from operators.
2) Single Drop: Nearly synonymous with "single haul," this term emphasizes the placement method when a trailer carries just one container. While some companies may use different terminology, the operational principle remains identical—prioritizing safety.
3) Double Haul: The opposite of single haul, this involves one trailer transporting two standard containers simultaneously. While improving transportation efficiency, this method significantly increases overloading risks when containers approach their weight limits.
4) Double Back: Primarily used in port loading/unloading operations, this refers to handling two containers side-by-side. Similar to double haul but occurring in different operational contexts, this method aims to improve efficiency but requires careful weight monitoring to prevent safety issues.
5) Shared Container (Consolidation): Distinct from ocean freight LCL (Less than Container Load), this involves multiple shippers sharing one container to optimize costs and space utilization through complementary cargo arrangements.
The Policy Background: Safety First
The rationale behind requiring "single drop" for standard containers exceeding 10 tons stems from the significantly increased accident risks when overloading occurs. This regulation directly originates from China's September 21, 2016 "921 Major Overload Control Policy," designed to curb overloaded transportation and protect road safety.
When a standard container exceeds 10 tons, using double haul methods dramatically escalates overloading risks, creating hazards for both vehicles and road infrastructure. The new policy therefore mandates the safer single drop approach.
These regulations impact every link in the logistics chain—carriers, loading companies, freight forwarders—all now face strict supervision and penalties for non-compliance. All transportation participants must rigorously follow the new rules to ensure safety and regulatory compliance.
In this rapidly changing industry, timely understanding and adaptation to new policies remains essential. Whether you're an industry newcomer or veteran, continuous learning and knowledge updating are indispensable. Through this exploration of new regulations and key terminology, we hope to enhance professionals' understanding of current freight forwarding realities and improve industry competitiveness.
