Ocean Sea Freight Container Types and Cargo Specifications 2 — Questions and Answers
Question 1: What is the maximum payload weight for a standard 20-foot dry container?
- Approximately 28,000 kg (61,700 lbs) (Correct answer)
- Approximately 15,000 kg (33,000 lbs)
- Approximately 40,000 kg (88,000 lbs)
- Approximately 10,000 kg (22,000 lbs)
Correct answer: Approximately 28,000 kg (61,700 lbs)
A standard 20-foot container has a maximum payload of approximately 28,000 kg, though actual limits depend on the carrier and route — some roads and ports have lower restrictions.
Question 2: What does 'VGM' stand for and why is it required for ocean freight?
- Verified Gross Mass — mandatory weight declaration required by SOLAS before container loading (Correct answer)
- Vessel General Manifest — the cargo declaration filed with customs
- Volume to Gross Mass ratio — used for freight rate calculation
- Verified Goods Measurement — a cargo inspection requirement
Correct answer: Verified Gross Mass — mandatory weight declaration required by SOLAS before container loading
VGM (Verified Gross Mass) is a SOLAS amendment requirement since July 2016 mandating that shippers provide the verified weight of packed containers to the carrier before loading to prevent dangerous stacking errors.
Question 3: What is an 'Out of Gauge' (OOG) shipment?
- Cargo that exceeds the standard dimensions of a container and extends beyond its edges (Correct answer)
- A shipment whose weight exceeds the container's maximum payload
- A container that does not conform to ISO standard measurements
- A shipment requiring customs examination due to undeclared goods
Correct answer: Cargo that exceeds the standard dimensions of a container and extends beyond its edges
OOG cargo extends beyond the standard dimensions of a container (width, height, or length), requiring special equipment like flat racks, open tops, or heavy-lift vessels and incurring additional surcharges.
Question 4: What is 'tare weight' of a shipping container?
- The weight of the empty container itself, excluding cargo (Correct answer)
- The weight of the cargo loaded inside the container
- The gross weight of the fully loaded container
- The weight limit stamped on the container door
Correct answer: The weight of the empty container itself, excluding cargo
Tare weight is the weight of the empty container — the gross weight (VGM) equals the tare weight plus the weight of all cargo, packaging, and dunnage inside.
Question 5: Which container type is used for non-palletized bulk dry commodities like grain, coal, or minerals?
- Bulk Container (Bulktainer) (Correct answer)
- Standard Dry Container
- Open Top Container
- Flat Rack Container
Correct answer: Bulk Container (Bulktainer)
A Bulk Container (bulktainer) has hatch openings in the roof for top loading of dry bulk commodities and discharge hatches at the base, unlike standard dry containers.
Question 6: What does 'CSC Plate' on a shipping container indicate?
- The container has been certified as safe for international transport under the Container Safety Convention (Correct answer)
- The container has passed a customs security inspection
- The container is approved for hazardous goods stowage
- The container meets refrigeration standards for food-grade cargo
Correct answer: The container has been certified as safe for international transport under the Container Safety Convention
The CSC (Container Safety Convention) plate certifies that the container has been inspected and meets structural safety standards required for stacking, lifting, and securing on vessels.
