Container Weight: Overweight Container Guide
Why are overweight containers and mis-declared weights a problem?
Following the entry into force of the amendments to SOLAS related to the VGM of loaded containers, domestic public ports - mainly under the administration of the state-owned entity Bolivariana de Puertos, S.A. (Bolipuertos, S.A.) - have implemented it, although with some misinformation and uncertainty. The reason for the former is attributable to the late publication of the guidelines on the matter by the INEA, as the maritime and port authority in Venezuela.
In the absence of guidelines on the subject, in the previous weeks to the entry into force, it was public understanding that for the purposes of complying with the VGM, shippers could use any public or private weighting equipment (weighbridges). However, on 30th June 2016 Bolipuertos, S.A. published the Circular BP-PRE-00013, stating that the ports under its control (Puerto Cabello, La Guaira, Maracaibo, Guanta, El Guamache and La Ceiba) had all weight equipment, calibrated and certified by the competent national governmental entity SENCAMER, also having a Compliance Certification issued by the INEA. The Circular caused surprise taking into account that by that time, no official information was known about the fact that weighting equipment would need another certification, apart from the one of SENCAMER. Since then, a great deal of confusion was created among exporters as to whether the VGM issued by Bolipuertos, S.A. was the only valid to proceed with the loading of containers. Consequently, there has been a significant degree of discretion by the public ports, in accepting the VGM issued by private weighbridges, usually located in the premises of exporters or yards outside the port area.
The INEA, on the other hand, has finally issued the Technical Norm and Guidelines for the implementation of VGM of loaded containers, through Providencia Administrativa No. 910 published in the Official Gazette No. 40,952 dated 26th July 2016. According to these guidelines, it is stated that the VGM is compulsory not only for ocean going shipments but also for cabotage (Art. 2); that the INEA will certify the companies and/or port administrations authorized to verify the gross mass of the loaded containers, having the suitable weighting equipment and procedures (Art. 3); it is accepted both measurement methods as prescribed by SOLAS, provided the weighting equipment is calibrated and certified by SENCAMER and it is able to provide a weighting ticket (Arts. 6, 7 and 8); it is required that the VGM must be inserted in the shipment declaration whose standard wording is included in Annex “A” (Art. 13); and also are listed the requisites for the port administration to be authorized by the INEA for the purposes of issuing the VGM, in which case a certification is issued by the former in the wording of Annex “B” (Art. 16). It is important to point out that the regulations in question do not mention anything about weight discrepancies nor the requisites for entities different than port administrations (for example, weighbridges at the exporters´ premises or yards outside port areas), to be certified by the INEA to issue the VGM, that it should presumably be the same prescribed by article 16. Finally, the INEA as the port authority will monitor and ask from shippers, carriers and port administrations for the procedures/documentation related to the VGM (Art. 17).
As per our last flash survey made among the main container lines serving Venezuela, it has been leaned that implementation of the VGM is advancing without complications and delays. Exportations are currently receiving from the governmental authorities utmost attention in terms of simplification of procedures, so that it is being accepted both the VGM issued by Bolipuertos, S.A. and any other private entity, provided the weighting equipment is certified by SENCAMER, it does not matter if it has the INEA´s certification. Additionally, shipping lines verify the compliance of the VGM, through the declaration made by the shipper to the carrier via its electronic systems in place.
Overweight containers and mis-declared weights are becoming a very serious problem - it is estimated that as many as 20% of containers are overweight or mis-declared. As containers are stacked higher to keep up with the growth of world trade, overweight and mis-declared weights can:
- Lead to vessels being improperly stowed, which can adversely affect vessel stability and possible loss of containers overboard.
- Cause damage to chassis and terminal handling equipment
- Injuries to dock workers while containers are handled in container yards
- Contribute to citations or accidents on highways and railways.
Overweight and mis-declared containers are caused by poor loading controls by shippers who try to maximize the space in the container.
How much cargo weight can be safely and legally loaded in containers for highway transport in the US?
The maximum cargo weight that can be safely and legally loaded, when a triaxle chassis is used, for most US areas is:
- In a 20” container - 44,000 lbs (19,958kg)
- In a 40” container - 44,500 lbs (20,185kg).
Shippers must be aware that when factoring in the truck, chassis and container weight, the maximum gross vehicle weight cannot exceed 80,000 lbs (36,287kg), which is the basic legal limit for US highway transport. Even though some states allow higher weight limits, we recommend that the cargo weight is limited to the above stated maximums. Shippers must spread the weight evenly throughout the container or the container can be subject to an axle weight violation.
How much cargo weight can be safely and legally loaded in containers for rail transport in the US?
The maximum weight that US railroads will accept or deliver for rail car movement is (including container weight) 52,900 lbs (23,995kg) in the case of a 20” container, and 67,200 lbs. (30,481kg) in the case of a 40” container. Commodities placing concentrated weight onto small areas of the container floor (such as steel coils, marble slabs etc.) are of particular concern to North American railroads because cargo can fall through the container floor and cause a derailment. Please note that containers loaded up to the rail cargo weight limit cannot move over the road as the container will exceed the 80,000 lb. highway limit.
Where are containers currently being weighed in the US?
Most marine terminals in the US weigh export containers during the in-gate process. Containers are also weighed at highway weight scale stations and some rail facilities. Import containers are not weighed prior to out-gate from marine terminals, and shipping lines rely on the bill of lading weight supplied by the shipper overseas to determine what action needs to be taken to safely and legally move the container.
What action should the shipping line take when they become aware that the container is overweight?
Containers found to be overweight should not be loaded onto the ship, or trucked over the road, until the shipping line has notified the shipper or consignee and advised what action the shipping line will take.
For overweight inbound containers, shipping lines can switch the bill of lading to “port to port” and force the consignee or shipper to arrange for trucking at their expense, and transfer risk for any fines or penalties that may result.
For overweight export containers moving from inland origins to the US west coast, shipping lines may have the option to use on dock rail services which eliminates the need for trucking to and from the port. Since these containers are not weighed when they arrive at the marine terminal, the shipping line and vessel planner are relying on the booked weight to stow the container on the vessel.
Shipping lines can utilise overweight corridors such as the Alameda corridor in Southern California or arrange overweight permits to truck the container to or from the rail. There is an additional cost to the shipping line for use of overweight corridor permit options, which can be billed back to the customer.
Shipping lines can utilise special equipment such as a three-axle chassis which allows for an additional 4,500 lbs. of cargo weight in a 20” container. Since these three-axle chassis are not in great supply, there is usually an additional charge when the shipping line uses them.
Shipping lines can arrange to have the overweight cargo reloaded into a second container with all costs billed back to the customer.
At no time should the shipping line force their trucker to accept an overweight container or urge the trucker to move the container at night, when there are less highway patrol officers working and/or highway scales operating.
What are the fines or penalties for overweight containers in the US?
Effective July 1, 2008 the Burlington Northern Santa Fe Railway will begin fining shippers (shipping lines are railway shippers) US$5,000 who tender overweight equipment. BNSF will be installing scales at ramps in Chicago, Memphis, Dallas, Houston and Los Angeles, and will begin weighing containers. For shipment weights that are mis-declared, the BNSF will fine shippers US$100 for each 1,000 lbs. mis-declared.
Shipping lines must insert a clause in the service contract to enable the shipping line to bill railway overweight fines back to the shipper that made the booking.
Shipping lines can impose fines to the shippers for overweight or mis-declared weights that arrive at marine terminals. If shipping lines decide to fine shippers for overweight or mis-declared containers, a clause in the service contract would be required. These fines act as a deterrent to force shippers to load legal weights and send a message to the shippers that the shipping lines will no longer tolerate such overloading of cargo by shippers.
Truck transport overweight container and axle weight violations vary from State to State in the US, and range from US$1,000 to US$5,000 per incident.
Steps a shipping line should take to ensure accurate weights are recorded at interchange points
When a booking is accepted, the shipper advises the shipping line the estimated cargo weight.
Once the cargo is actually loaded in the container and the container is scaled at an off-dock weight station, or during the in-gate process at a marine terminal, the accurate weight should be passed to the shipping line so appropriate action can be taken to load or move the container.
Each shipping line should have a process in place to ensure that the actual weight of the container is communicated to the vessel planner in order to arrange proper stowage on the vessel.
The Ocean Carrier Equipment Management Association (OCEMA) has published weight guidelines for cargo transport on their website at www.ocema.org/cwg.htm and www.ocema.org/members.html.
