Container Loading Supervision Service

1.Supervision Requirements
Supervision involves loading products into the container under oversight, ensuring the following requirements are met:
1) Products meet requirements: Ensure the products are correct and the number of cartons is accurate.
2) Container is suitable for shipment: Ensure the container is not damaged and is clean; the arrangement of products inside the container is suitable for transport; record the product quantity, container number, and lock number.

2.Supervision Process
1) Obtain documents from the office and contact the factory;
2) Upon arrival at the factory, confirm with the factory representative whether the container has arrived. If not, further confirm the estimated time of arrival and inform the office;
3) Count the products and compare with customer documents;
4) Sample cartons and take photos: stacking, outer cartons, marks, products. The number of cartons to sample is the square root of X multiplied by 0.6, with a minimum of 5 cartons for the supervision process;
5) Check the exterior of the container: no damage, container number clear and correct;
6) Check the interior of the container: no damage, floor clean, container number clear and correct/missing. During the day, close the doors to check for light leaks. On rainy days, check the floor, walls, and roof for water stains. If the floor is dirty, request the factory to clean it as part of the supervision process;
7) Key locations for the container number: exterior side wall, interior side wall near the right door, upper part of the right door exterior;
8) Take photos: (using a 40' container as an example) empty container, 1/4 loaded, 1/2 loaded, 3/4 loaded, 100% loaded, right door closed, both doors closed, close-up of the lock position after locking, photo of the lock number (close-up), close-up of the locking rod (right door) lower slot (door) rivet (especially for shipments to Eastern European countries).

3.Common Issues and Precautions
1) Issue: The front half of the container is fully loaded, while the back half is empty, cartons are thrown around, not neatly arranged. The front half is fully loaded, the back half has a steep height difference, lacking effective cushioning.
Note: Carton stacking should be reasonable, with similar heights inside and out (preferably only one layer difference), to prevent tilting or falling during transport and handling.
Avoid having the front half fully loaded and the back half empty, or a large height difference. Create a step-like arrangement with at least 2-3 cartons (horizontally) for cushioning, or ensure the last cartons are not loaded all the way to the door.
2) Requirements: Inspectors have the responsibility and obligation to remind the factory to achieve this during supervision. Otherwise, it must be noted in the report.
(1) Count before/during supervision - counting before supervision helps us grasp the overall situation;
(2) Open cartons for inspection and take photos during supervision - the number to open is the square root multiplied by 0.6;
(3) Check if the container is suitable before supervision - dirty, holes, etc.;
(4) Estimate the volume of packaging cartons during supervision - to ensure reasonable stacking;
(5) If it doesn't fit: Plan the layout in advance to avoid reloading;
(6) Just right;
(7) A lot of empty space
① From the start, avoid stacking cartons too high, prevent one end reaching the top and the other the bottom, ensure similar heights front and back, especially with the last rows descending in steps.
② If cartons vary in weight, place heavier ones at the bottom, preferably distributed front, middle, and back, to avoid the container being light on one end and heavy on the other.
③ Pay special attention: the last row must be arranged to the door, with no significant gaps in between (the minimum size carton shouldn’t fit).
Attached. Introduction to Container-Related Content
Types of Containers
1) Classification by Material
Based on the material used for the main components (side walls, end walls, roof, etc.), containers are named accordingly. Classified by material, containers can be divided into three types:
(1) Aluminum alloy containers: advantages include light weight, attractive appearance, corrosion resistance, good elasticity, ease of processing, low processing and repair costs, long service life; disadvantages include high cost and poor welding performance;
(2) Steel containers: advantages include high strength, sturdy structure, good weldability, excellent water tightness, low price; disadvantages include heavy weight and poor corrosion resistance;
(3) Fiberglass reinforced plastic (FRP) containers: advantages include high strength, good rigidity, large internal volume, thermal insulation, corrosion and chemical resistance, easy cleaning, simple repairs; disadvantages include heavy weight, susceptibility to aging, and reduced strength at bolt points.
2) Classification by Structure

4.Containers classified by structure can be divided into three categories:
(1) Interior post type container and exterior post type container, mainly referring to aluminum alloy containers. Interior post type means the side posts (or end posts) are located inside the side or end walls; exterior post type means the side posts (or end posts) are located outside the side or end walls;
(2) Collapsible container: refers to containers whose main components (side walls, end walls, and roof) can be easily folded or disassembled, and conveniently reassembled when needed;
(3) Monocoque container: integrates all components into a single steel body, with advantages including light weight and ability to withstand torsional forces without permanent deformation.
3) Classification by Purpose
Classified by purpose, containers can be divided into:
(1) Dry container: suitable for various goods that do not require temperature control, generally referred to as general-purpose containers. Mainly used for transporting general cargo, it is the most common type.
(2) Refrigerated container: equipped with refrigeration units, allowing temperature adjustment from +25°C to -25°C, with inner walls lined with low thermal conductivity materials. During transport, the refrigeration unit maintains the required temperature. The top inside has hooks and rails for hanging meat and fruit, suitable for frozen foods, fresh fruits, or special chemical products, typically maintaining temperature for about 72 hours.
(3) Solid bulk container: used for loading powdered, granular, and various bulk goods.
(4) Open top container: suitable for heavy goods like glass panels, steel products, machinery, allowing loading and unloading by crane from the top. The top can be opened or is not fixed.
(5) Flat rack container: consists of a base and metal frames on all sides, suitable for long, overweight, or light bulky goods.
(6) Tank container:
(7) And some special-purpose containers, such as car containers, livestock containers, hide containers, platforms, etc.
