How Chargeable Weight Is Derived
- Billing weight is the higher of actual weight and volumetric weight.
- Volumetric weight formula: (Length x Width x Height) / 5000 (dimensions in cm, output in kg).
- Shipping weight adds packaging weight (dunnage): 100 g for Standard, 500 g for Heavy Bulky.
- Final weight is then rounded as per slab logic.
Example 1: Actual Weight Dominates
Inputs
| Actual Weight | Dimensions (cm) | Volumetric Weight | Shipment Type |
|---|---|---|---|
| 0.80 kg | 20 x 15 x 10 | 0.60 kg | Standard |
Computation
Billing weight = max(0.80, 0.60) = 0.80 kg
Shipping weight before rounding = 0.80 + 0.10 = 0.90 kg
Final rounded weight = 1.00 kg
Example 2: Volumetric Weight Dominates
Inputs
| Actual Weight | Dimensions (cm) | Volumetric Weight | Shipment Type |
|---|---|---|---|
| 0.45 kg | 35 x 25 x 20 | 3.50 kg | Standard |
Computation
Billing weight = max(0.45, 3.50) = 3.50 kg
Shipping weight before rounding = 3.50 + 0.10 = 3.60 kg
Final rounded weight = 4.00 kg
Example 3: 3 kg Shipment and Slab Tiering
Inputs
| Actual Weight | Dimensions (cm) | Volumetric Weight | Shipment Type |
|---|---|---|---|
| 2.70 kg | 38 x 28 x 14 | 2.98 kg | Standard |
Computation
Billing weight = max(2.70, 2.98) = 2.98 kg
Shipping weight before rounding = 2.98 + 0.10 = 3.08 kg
Final rounded weight = 4.00 kg
Tiering View
| Standard Weight Slab | Applicable? | Why |
|---|---|---|
| <= 500 g | No | Final weight is above 0.5 kg |
| > 500 g and <= 1 kg | No | Final weight is above 1 kg |
| > 1 kg and <= 2 kg | No | Final weight is above 2 kg |
| > 2 kg and <= 5 kg | Yes | Final weight 4.00 kg falls in this tier |
| > 5 kg | No | Final weight is not above 5 kg |
Example 4: Heavy Bulky Trigger + Dunnage
Inputs
| Actual Weight | Dimensions (cm) | Reason | Shipment Type |
|---|---|---|---|
| 24.0 kg | 120 x 55 x 40 | Weight > 22.5 kg | Heavy Bulky |
Computation
Billing weight = max(actual, volumetric) = 52.80 kg (illustrative)
Dunnage add = 0.50 kg
Shipping weight before rounding = 53.30 kg
Final rounded weight = 54.00 kg
Quick Summary Table
| Case | What Decides Chargeable Weight | Typical Impact |
|---|---|---|
| Dense item | Actual weight dominates | Lower risk of slab jump |
| Bulky light item | Volumetric weight dominates | Higher slab risk |
| Mid-weight shipment (for example 3-4 kg) | Falls in >2 kg and <=5 kg tier after rounding | Per-kg tier charge applies |
| Heavy Bulky | Heavy criteria + 500 g dunnage | Higher base slab + add-ons |
