What is a non-machinable parcel?
A non-machinable parcel is any parcel that cannot be processed through a carrier’s automated sorting system and requires manual handling due to its size, shape, or content. Most shipping carriers like CIRRO E-Commerce uses automated sorting machines to quickly process parcels. However, certain packages don’t fit the standard criteria for machine sorting, leading to higher shipping costs and extra handling time.
The categories of non-machinable parcel
To help businesses understand when a parcel is considered non-machinable, here are some common categories:
| Non-machinable parcels | The challenges of non-machinable parcel processing |
| Oddly shaped items Deviate from standard box shapes—such as tubes, spheres, or other irregular forms. | Unconventional geometry may cause jams or misalignment during handling. |
| Cylindrical items Products with excessive curvature, such as rolling tubes or barrels. | Cylindrical parcels tend to roll, shift, or jam sorting equipment, requiring manual handling. |
| Non-standard dimensions Items that do not conform to traditional square or rectangular shapes may not fit conveyor guidelines. | Parcels are too long, too wide, too tall require manual intervention. Shipping carriers rely on standardized slots to process parcels, and anything that doesn’t conform to predefined size limits are not acceptable. |
| Improper packaging Poorly packed items—such as those wrapped in string, containing loose components, or with protruding parts. | Improper packaging can easily get caught in sorting machinery or suffer damage during transit. |
| Fragile or hazardous items Fragile items are products that can easily break, crack, or get damaged during transit. Hazardous items are substances that pose a risk to health and safety. | They often need additional padding, specialized packaging, or “Handle with Care” labels, while hazardous items must comply with safety regulations for proper handling, storage, and transportation. |
| Unshielded magnets Unshielded magnets are magnetic materials that are not properly enclosed or contained to prevent their magnetic fields from interfering with nearby objects. | If the magnetic field extends beyond 0.00525 gauss at a distance of 7 feet, it can disrupt electronic equipment or attract metallic objects, posing potential risks. |
Why should you pay attention to non-machinable parcels?
Unlike standard parcels that move seamlessly through automated sorting systems, non-machinable parcels demand extra handling, which can slow down delivery and increase operational inefficiencies.
For e-commerce retailers shipping in high volumes, the additional handling fees can quickly escalate, cutting into profit margins. By optimizing packaging and ensuring compliance with carrier requirements, businesses can minimize unnecessary expenses and improve shipping efficiency.
How to avoid extra handling fees and optimize shipping costs?
Use standard box sizes
Always stick to regular rectangular boxes that fit within carrier guidelines. Avoid odd or cylindrical shapes.
Secure packaging properly
Ensure that all contents are packed tightly without shifting inside. Use fillers like bubble wrap or air cushions to maintain stability.
Choose rigid materials
Use strong corrugated cardboard instead of soft mailers when shipping irregularly shaped items.
Distribute weight evenly
Keep the parcel balanced to prevent it from tilting or shifting during transit.
Best practices for cost-effective packaging
Use the right box strength for the item
Choose double-walled or reinforced boxes for fragile and heavy items to prevent damage during transit. Avoid using unnecessarily thick boxes for lightweight products, as they add extra weight and cost.
Shrink wrap or bundle loose items
If shipping multiple small items, bundle them together using shrink wrap or secure them in a structured parcel to prevent shifting inside the box.
Choose poly mailers for lightweight items
Whenever possible, opt for flat, flexible poly mailers instead of boxes to reduce weight and avoid non-machinable classification.
