We often hear about cargo seal in the world of shipping. But what are they?

Cargo seals are strictly linked to cargo shipping.

Cargo shipping is the transport of goods by specialized ships that carry different types of goods such as oil, scrap metals, white-goods, iron ore, diesel and petrol, food and drink, electrical and electronics equipment, raw materials for manufacturing and commodity bulk cargo such as coffee.

The majority of consumer goods are carried by container ships which are sealed with cargo seals. It’s about 20-foot long containers, known as twenty foot equivalent units (TEU).

The largest vessels commissioned in 2019/2020 can carry up to 23,000 TEU and these are deployed predominantly on the most profitable China-US Pacific routes.

The COVID-19 pandemic has caused major fluctuations in trade across the world, and this affected container shipping and carriers. Profits have improved substantially, in some cases by record margins, as consumer demand has boomed, coinciding with high freight rates and low bunkering prices. Also cargo seals have been affected by high increases. However their cost remains irrelevant compared to their service/use.

Cargo seals must be compliant with ISO 17712:2013 (High security container seals).

They are divided into two large groups:

Traditional cargo seals (mechanical seals), RFID cargo seals ( with RFID technology)
