Understanding volumetric weight and following these tips can prevent unexpected costs at checkout.
Why "Weight" Isn't Always What It Seems: Volumetric Weight
Carriers charge based on the space a package occupies on their vehicles, not just its actual weight. To account for this, they use a concept called volumetric weightgreater
How CNFANS Calculates Volumetric Weight
The standard formula used by most agents and carriers is:
Volumetric Weight (kg) = (Length (cm) × Width (cm) × Height (cm)) ÷ Volumetric Divisor
Key Point:"Volumetric Divisor"
Example:
Volumetric Weight (using /5000) = (40 × 30 × 20) ÷ 5000 = 24000 ÷ 5000 = 4.8 kg.
If the actual weight is 3.2 kg, you will be charged for 4.8 kg.
Tips for Accurate Cost Estimates Before Checkout
1. Provide Detailed Product Information
When submitting a purchasing order, include product links and note if the item is particularly bulky (e.g., shoes in their box, pillows, packaging for collectibles). This helps your agent give a more informed initial estimate.
2. Request Pre-Warehouse Photos & Measurements
Before consolidating parcels, you can ask CNFANS to provide photos and measurements (length, width, height) of your items in the warehouse. This allows you to calculate the potential volumetric weight yourself before paying for international shipping.
3. Consider "Simple Packing" or Removal
Request the removal of original retail boxes, excess packaging, and unnecessary tags. Ask for "simple packing" to minimize the final parcel size. A flatter, tighter package can significantly reduce its volumetric dimensions.
4. Use the Rehearsal Packaging Service
This is the most accurate method. For a small fee, CNFANS will pack your items together, weigh them, and measure the final parcel before you pay for international shipping. You will receive the exact weight and dimensions, eliminating all estimation errors.
5. Understand Carrier Divisor Differences
Check CNFANS' shipping lines guide. A line with a higher volumetric divisor (e.g., 7000 vs. 5000) will yield a lower volumetric weight, often making it cheaper for bulky, light items. Choose your carrier strategically.
6. Ask for an Expert Check
If you're unsure, contact CNFANS customer service. Describe your items, and they can often give you advice on potential volumetric issues based on experience.
