Chargeable Weight
Chargeable weight is the weight on which freight is billed — MAX(actual weight, volumetric weight). The atomic unit of courier pricing.
What is chargeable weight?
Chargeable weight is the weight a courier uses to bill a shipment. It's the maximum of actual weight and volumetric weight — also called billable weight or DIM weight.
Why it matters operationally
Courier rate cards are organised by weight slab. The chargeable weight determines which slab applies. A 500g actual-weight SKU that volumetrics to 1.4kg ends up in the 1.5kg slab, paying 2–3× the rate of the 500g slab. Understanding chargeable weight is the foundation of accurate shipping cost prediction.
Worked example — B2C ecommerce
A D2C cushion brand ships a 30 × 30 × 8 cm cushion (actual 500g). Volumetric = 7,200 ÷ 5,000 = 1.44 kg. Chargeable = MAX(0.5, 1.44) = 1.44 kg. Billed at 1.5 kg slab.
Worked example — B2B logistics
A B2B manufacturer ships 25 kg dense cargo (compressed FMCG). Volumetric = negligible relative to actual. Chargeable = actual = 25 kg. Conversely, 25 kg of bulky-but-light cargo (lampshades, packaging foam) might volumetric to 60–80 kg — radically different bill.
How a multi-carrier platform handles chargeable weight
Multi-carrier platforms calculate chargeable weight at order entry and route to the carrier with the most favourable slab structure for the SKU. Some carriers have wider slabs (less penalty for being just-above-slab); others have tighter slabs.
Quick reference card
| Attribute | Detail |
|---|---|
| Formula | MAX(actual weight, volumetric weight) |
| Volumetric formula | (L × W × H cm) ÷ 5000 (surface) |
| Synonyms | Billable weight, DIM weight |
| Slab impact | Determines which weight slab applies |
| Disputable | Yes (60–80% recovery with evidence) |
| When dead-weight wins | Dense cargo (metal, books, electronics) |
| When volumetric wins | Bulky-light (foam, textiles, decor) |
| Biggest lever | Right-size packaging per SKU |
One-paragraph summary: Chargeable weight is the atomic unit of courier billing. It's the higher of actual weight and volumetric weight — couriers bill the slab corresponding to chargeable weight. A 500g cushion in an oversized box can end up in the 1.5kg slab, paying 2–3× the actual-weight rate. Right-sizing packaging is the largest single lever to reduce chargeable weight; multi-carrier platforms add weight-discrepancy disputes as a secondary recovery mechanism.
Operator playbook — chargeable weight in practice
A practical playbook for managing chargeable weight:
- Audit declared vs measured weight monthly — every AWB where carrier-measured exceeds declared by >5% is a dispute candidate.
- Right-size packaging by SKU. Maintain a packaging size matrix per SKU profile (small / medium / large) to minimise volumetric weight.
- Use mailer bags for soft goods (apparel, accessories) — mailer ≈ actual weight pricing.
- Vacuum-pack textiles to compress volumetric weight on cushions, blankets, towels.
- Negotiate slab boundaries at scale — the boundary between 500g and 1kg slab is more valuable than 5% per-kg discount.
- Track weight discrepancy % per courier weekly. If one carrier consistently over-measures, escalate or reallocate.
- Train packing team on dimension measurement — incorrect declared dimensions trigger weight disputes you can't win.
Frequently asked questions
How is chargeable weight calculated?
Chargeable weight = MAX(actual weight, volumetric weight). Volumetric = (L × W × H in cm) ÷ 5000 for surface.
Why is my chargeable weight higher than my product's actual weight?
Because volumetric weight exceeded actual. Bulky-but-light SKUs (textiles, foam, cushions) typically have higher volumetric than actual.
Can I reduce chargeable weight by changing packaging?
Yes — right-sizing the box reduces volumetric weight. Mailer bags reduce volumetric to near-zero on soft goods. Vacuum packing reduces volumetric on textiles.
Does chargeable weight differ between surface and air?
Yes — surface uses divisor 5000, some air carriers use 6000 (lower volumetric, but per-kg air rate is higher).
Is chargeable weight the same as dead weight?
No. Dead weight = actual physical weight. Chargeable weight = MAX(actual, volumetric).
Can I dispute chargeable weight?
Yes — if the carrier's measured dimensions exceed your packed dimensions, raise a weight dispute with packed-photo evidence. 60–80% recoverable with disciplined workflow.
How often should I audit chargeable weight?
Weekly for high-volume operations. Monthly for SMB. Carrier-measured discrepancies > 5% from declared are dispute candidates.
Does chargeable weight affect COD handling fee?
No — COD handling fee is based on order value, not chargeable weight. But chargeable weight affects base freight which then affects total.
Can chargeable weight be lower than dead weight?
No — chargeable weight = MAX(actual, volumetric) ≥ dead weight always.
