Container loading supervision services are definitely not excessive services. If you encounter some special circumstances but don't purchase this service, you may regret it.
The most outrageous thing I have ever seen is that factories secretly replace goods that have passed customer inspection with inferior products in stock, and even use empty containers to bottom the list. No one is watching. Once the cabinet door is closed, you will find that the goods are not right when you arrive at the port. It is too late for anything.
In addition, you may encounter situations of missing or underloading. Without a loading supervision report, how do you prove that the factory missed and underloaded parts rather than missing parts from the warehouse at the destination port?
Even if there are no problems with the goods in the factory, workers may still encounter barbaric loading and unloading, and the boxes will be broken and dirty, and they will be quickly stuffed deep into the container while no one is in charge of them. By the time I crossed the ocean to your warehouse, the goods inside were crushed and moldy.
There are also some special circumstances, such as incorrect packing method, heavy goods weighing light goods, and no reinforcement net. A customer I once made ceramics did not supervise the installation. The factory placed large plates upright against the cabinet wall. When the container was opened at the port of arrival, one-fifth of it broke.
This service can help you avoid these problems with a high probability. Spend a small amount of money to grasp the last link in the transnational procurement chain and reduce accidents. You decide for yourself whether it is worth it.
