Weight is the quietest way an export shipment goes wrong. Nobody argues about it at the negotiation stage, the figures look comfortable on paper, and then a container is refused at the terminal gate two days before the vessel closes. Understanding how the numbers actually stack up on a reefer of Egyptian produce takes about ten minutes and saves a rolled booking.

What VGM is and who signs it

Under the SOLAS amendment in force since 2016, no packed container may be loaded onto a vessel unless a Verified Gross Mass has been declared by the shipper and passed to the carrier and the terminal before the documentation cut-off. VGM is the total: cargo, packaging, dunnage, pallets, and the tare weight of the container itself.

Two methods are accepted. Method 1 is weighing the packed and sealed container on a calibrated weighbridge. Method 2 is calculating the sum of the individual weights of cargo, pallets and packing material and adding the tare stencilled on the container door. Egypt permits both. Method 1 is the safer choice on produce, because actual carton weights drift above nominal weights once fruit is packed to a minimum net weight rather than an exact one.

The numbers on a 40 ft high cube reefer

A 40 ft high cube reefer has a tare weight of roughly 4,600 to 5,000 kg depending on the unit and the maker. Maximum gross weight is commonly 34,000 kg, which leaves a theoretical payload near 29,000 kg. That figure is almost never the real limit.

The binding constraint is usually the road. Egyptian axle and gross vehicle weight limits, and the equivalent limits on the destination side, cap what a trailer can legally carry between the packhouse and the terminal. In practice most lines and hauliers will work to a payload ceiling in the region of 24,000 to 26,000 kg for a 40 ft reefer moving to Alexandria or Damietta. Some destination markets impose stricter limits again, and a container that is legal leaving Egypt can be undeliverable on arrival.

Where produce loads sit against that ceiling

Most fresh produce cubes out before it weighs out, which is why the issue catches people by surprise on the loads that do not. A 20 pallet reefer of citrus in 15 kg cartons at 90 cartons per pallet is carrying roughly 27,000 kg of fruit plus about 500 kg of pallets, which is already at or over the working ceiling. Onion in 20 kg mesh bags and potato in 25 kg bags are heavier still. Guidance on carton and pallet builds by crop is set out in our note on palletisation and ISPM 15 for Egyptian produce.

By contrast, a mango or fig reefer in 4 kg cartons will fill the cube at around 14,000 to 18,000 kg and never approach the weight limit. IQF product in 10 kg cartons sits in between.

Practical rules that prevent problems

• Fix the payload target in writing at the time of booking, not at loading. Ask the line for its maximum accepted VGM on the specific service and the specific destination port.
• Use actual weighbridge figures rather than nominal carton weights. A carton labelled 15 kg net is frequently 15.3 to 15.6 kg gross once tray, liner and carton are counted.
• Count the pallets. Twenty heat-treated wooden pallets add 400 to 600 kg that is easy to forget in a Method 2 calculation.
• Submit VGM ahead of the terminal cut-off, not at it. A late VGM is treated the same as a missing one.
• If a load is genuinely at the margin, reduce by one layer per pallet rather than by one pallet. The cube stays balanced and the stow stays tight.

What happens when it goes wrong

An overweight container is stopped at the terminal gate. The options from there are all expensive: destuff and repack, which on chilled produce means a break in the cold chain, or return to the packhouse and reload, which usually means missing the vessel. Storage, haulage and a rolled booking follow. On a shipment carrying a letter of credit with a fixed latest shipment date, the consequences reach further than the freight bill, as covered in our note on the full export document set.

None of this is difficult to manage. It simply needs to be agreed before the fruit is packed rather than discovered afterwards.
