One of the most common surprises during checkout is a final shipping cost higher than the initial estimate. Often, this is due to weight miscalculations. Understanding how CNFANS calculates volumetric weight
Couriers charge based on the space your package occupies on a vehicle, not just its actual physical weight. This is known as volumetric weight
Carriers will charge you based on the greater of the two weights. For lightweight but bulky items, volumetric weight is almost always the chargeable weight. Our system follows the standard international freight formula to protect our users from unexpected carrier adjustments. The typical volumetric divisor6000
A box measuring 40cm × 30cm × 20cm has a volumetric weight of (40 × 30 × 20) / 6000 = 4 kg. If the item's actual weight is 2.5 kg, you will be charged for 4 kg. Proactively manage your shipping costs with these strategies: By understanding the role of volumetric weight

Key Tips for Accurate Estimates Before Checkout
Don't guess. Use a ruler or tape measure for the packaged item. Include the outer box/packaging in your length, width, and height inputs in your CNFANS shopping cart.
Before consolidating and paying, you can opt for our rehearsal service. Our warehouse team will physically pack, measure, and weigh your items, giving you a final, guaranteed chargeable weight
While bundling items often saves money, a very large box can trigger a high volumetric weight. Sometimes, splitting into two sensible packages can be cheaper. Use our cost calculator to compare.
Ask CNFANS to remove bulky shop boxes, blister packs, or excess filler before shipment. This reduces the final package dimensions significantly.
Sellers occasionally list incorrect item weights. Be cautious with items listed as 0.1kg or 1g; they are often placeholders. Research the actual weight or contact the seller.
