A Comprehensive Guide to Special Container Shipping: Regulations & Requirements

Introduction
In international ocean freight, special containers are critical for shipping goods that are out-of-gauge (OOG), overweight, temperature-sensitive, or otherwise non-standard. This guide details the types of special containers, suitable cargo, selection criteria, and core shipping regulations to help you arrange safe and efficient logistics.

1. Common Types of Special Containers & Their Functions

Special containers are modified from standard dry containers to meet specific cargo needs. The primary types include:

Container Code	English Name	Key Features & Purpose
OT	Open Top	Removable top for top-loading oversized and tall cargo via crane.
FR	Flat Rack	No roof or side walls, allowing loading from all sides for super-wide and heavy goods.
RF	Reefer	Integrated temperature control system for perishable goods.
SA/SAF	Standalone Assembly Frame	Customized frame designed for specific equipment (e.g., power generators).
ES/EQ/BQ	Saddle Tank	Specialized tank containers for transporting liquids or gases.

2. Cargo Compatibility & Container Selection Guide

To ensure cargo safety and compliance, please select the correct container type based on your goods:

Cargo Category	Specific Examples	Recommended Container	Key Regulations / Notes
Heavy Machinery & Vehicles	Excavators, Loaders	FR, SA	Accurate weight, dimensions, and center of gravity must be provided.
	Trucks, Buses	OT, FR, EQ	Must be securely lashed; tires require chocking.
Out-of-Gauge (OOG) Cargo	Wind turbine blades, Transformers	FR, SA	If dimensions exceed standard FR limits, an OOG application is mandatory.
	Power transmission towers, Large structures	FR	Detailed stuffing and securing plan is required.
Temperature Controlled & Dangerous Goods	Perishable Foods, Pharmaceuticals	RF	Precise transport temperature must be confirmed and set in advance.
	Liquid chemical tanks, LNG tanks	ES/EQ (Tank)	Accurate Material Safety Data Sheet (MSDS) must be provided.
Other Special Cargo	Paper rolls, Bulk goods in ton bags	FR, OT	Protection against moisture and proper securing to prevent rolling are essential.
	Ship components, Modules	SA, FR	Special requirements for lashing points and load-bearing structures.

3. Core Shipping Regulations & Operational Procedures

Shipping with special containers involves strict rules and complex operations. Key steps and requirements are as follows:

Advanced Booking & Approval
- Lead Time: Special container space is limited. You must submit a booking request at least 2-4 weeks in advance.
- Detailed Information: You must provide the exact weight, three-dimensional measurements (LxWxH), center of gravity, photos, and a detailed cargo description.
- OOG Application: If the cargo exceeds standard dimensions or weight, an Out-of-Gauge (OOG) application is mandatory to obtain approval from the carrier and ports.
Strict Packaging & Securing Requirements
- Unpackaged Goods: Use wooden blocks or rubber pads at contact points between the cargo and container. Securing with lashings and steel straps at multiple points is crucial to prevent shifting or tipping during transit.
- Anti-Corrosion & Moisture Proof: For precision equipment or steel products, appropriate anti-rust and waterproof packaging is required based on the voyage and environment.
Professional Loading & Unloading Operations
- Professional lifting equipment (e.g., cranes, forklifts) must be used.
- The loading process must strictly follow the provided stuffing plan to ensure stability and safety.
Documentation & Insurance
- Special Documents: Dangerous goods require an MSDS and a Dangerous Goods Package Certificate. OOG cargo may require a Cargo Securing Certificate.
- Cargo Insurance: It is highly recommended to purchase comprehensive marine cargo insurance for high-value special goods to mitigate potential transit risks.
