❔ The Did You Knows? ❓VGM - Verified Gross Mass

Have you ever wondered how a shipping vessel maintains its stability while at sea with all those heavy containers on board? There is a sizeable amount of planning that goes into protecting vessel stability, preventing stack collapses and ensuring the safety of port and dock workers.

Verified Gross Mass or VGM is the total weight of a packed shipping container, verified by the shipper as required by International Maritime Organizations (IMO) Safety of Life at Sea (SOLAS) regulations. This mandatory requirement which came into effect internationally in July 2016, ensures the safe loading of containers onto vessels by preventing accidents caused by overweight or incorrectly declared containers.

There are two generally accepted methods of declaring a VGM:

  1. Weighing the packed container and all its contents using certified equipment. Trucks generally utilise weigh bridges as a means of calculating this.
  2. Weighing the cargo (goods weight), dunnage (packaging weight) and empty container (tare weight) separately and then summing these weights to calculate the container's total gross mass.

But who is responsible for declaring the VGM?

The shipper is legally responsible for providing the accurate VGM for each and every packed container delivered to the shipping line.

No packed container is allowed to be loaded onto a ship unless a VGM has been provided.

A missing or incorrect VGM declaration can lead to rejections and delays of containers loading a vessel. This may result in a container being rolled to the next sailing. Subsequently, additional charges may apply in the form of storage, demurrage, rebooking fees, and/or emergency weighing at the terminal.

Fines, penalties, insurance validity complications as well as legal action can also be the result of serious VGM compliance issues. It is important from a health and safety perspective to ensure all those operating at sea and around shipping vessels remain safe.

❔ The Did You Knows? ❓Approved Transitional Facilities

Importing into New Zealand is different to the rest of the world. We are largely a country free from the pests seen in other parts of the world. Sure, we are an island in the middle of the Pacific, but our borders are kept safe from a biosecurity perspective due to regulations set to manage those risks. One example; import containers into New Zealand need to be opened, inspected and signed off at an Approved Transitional Facility (ATF) before being released to the importer.  What is an Approved Transitional Facility? An ATF is an MPI approved location where goods that may carry biosecurity risks can be temporarily held, unpacked, and inspected upon importation to New Zealand. These locations operate under strict biosecurity standards acting as a secure buffer zone to prevent pests, diseases and contaminants from entering the country. NZ relies on strict biosecurity to protect native environments and agriculture; meaning that on arrival, goods cannot automatically move from the port to your warehouse without first being inspected.  Behind the scenes of every New Zealand ATF is a Transitional Facility Operator (TFO) whose responsibility it is to manage and maintain the biosecurity procedures of their ATF. The TFO assumes control of the outright risk at the facility, knowing and understanding goods approved to be received, processes to follow should risks be identified, ensuring overall compliance of the site and its people, as well as the goods it holds.  Terms like MPI, TFGEN, AP, BMSB and Risk Goods get thrown around daily in our environment, but what do they actually mean?  MPI – The Ministry for Primary Industries is the government department responsible for the biosecurity sector in New Zealand. They are ultimately responsible for managing the biosecurity border risk to New Zealand. TFGEN – Transitional Facilities for General Uncleared Risk Goods. Every ATF needs one, and every TFO needs to know theirs back to front. It’s their procedure manual; their Personal Business Bible illustrating everything their ATF is approved to handle, down to which employees are approved to handle risk goods. Processes are outlined to ensure the ATF is compliant to manage imported goods and the risks associated with them. AP - Alongside the TFO are Accredited Person(s). While the TFO oversees the overall biosecurity procedures of the ATF, the APs supervise the unpacking and manage biosecurity risks at a container and goods level. Inspecting imported cargo for pests, or contamination of varying types is front and foremost for any AP. Each container arriving into a facility is signed off by an AP before goods can be released to the importer. Risk Goods – These are any goods that could contain or harbour harmful pests, diseases, or organisms that threaten the environment, economy or human health of New Zealand. All goods are considered risk goods prior to their arrival into NZ and sign off by an ATF, but not all risk goods are equal. Raw/fresh animal products carry a higher risk than finished furniture for example due to the nature, processing and finishes of goods. Specific ATFs are approved to handle higher risk goods with higher compliance requirements. BMSB – The Brown Marmorated Stink Bug is a pest native to Asia that has spread throughout Europe and Northern America. NZ has spent close to a decade on full alert in an effort to keep this pest off our shores; BMSB Season is Back! - Hobbs Global Operating an ATF is expensive, particularly as compliance continues to get stricter but doing so may provide benefits to your company.
