DHL Volumetric Weight Divisor 2026: 5000 vs 6000 Calculation

The Short Answer

For DHL Express international shipments, the standard volumetric divisor is 5000 (using centimeters). This means dividing the volume by 5000 results in a higher billable weight than the older 6000 divisor. Always calculate: (L × W × H) / 5000 to determine chargeable kilograms.

5000 vs. 6000: The Difference Explained

Historically, IATA set the standard volumetric divisor at 6000 ccm/kg. This meant 1 cubic meter of cargo was considered equivalent to 167 kg. However, as lightweight e-commerce parcels flooded air networks, density decreased.

To protect revenue, carriers like DHL moved to a 5000 divisor. This equates 1 cubic meter to 200 kg.

Impact: The lower the divisor, the higher the calculated weight. A package that was 10kg volumetrically under the 6000 rule is 12kg under the 5000 rule—a 20% price increase for shipping the exact same box.

DHL Calculation Formulas

Depending on your unit of measurement, the formula changes but the result (the density ratio) is effectively the same.

Metric System (cm / kg)

(L × W × H) ÷ 5000

Example:
Box: 40 × 30 × 20 cm
Volume: 24,000 ccm
24,000 / 5000 = 4.8 kg

Imperial System (in / lbs)

(L × W × H) ÷ 139

Example:
Box: 16 × 12 × 8 in
Volume: 1,536 cu in
1,536 / 139 = 11.05 lbs

Exceptions to the Rule

Not every shipment uses 5000. It depends on the service level and your specific contract negotiation.

DHL Global Forwarding (Air Cargo): Often uses 6000 (1:167) for freight shipments booked as cargo rather than express courier.
Domestic Road Freight: In some European regions, road freight uses divisors like 3000 or 4000 due to truck density being higher than aircraft.
Negotiated Rates: High-volume shippers (e.g., spending $1M+/year) can sometimes negotiate a custom divisor (e.g., 6000) as part of their contract to lower costs on fluffy items.

The 'Rounding Up' Trap

Warning: DHL measures to the nearest 0.5cm but calculates price on integer dimensions.

If your box bulges to 30.1 cm, DHL scans it as 31 cm.
Always measure your box when PACKED and BULGING, not empty. Tape adds thickness. If you design a custom box at strictly 30.0 cm, a single layer of tape might push it to 30.2 cm, bumping your billable weight significantly across thousands of shipments.

DivisorThe number used to convert cubic volume into billable weight (e.g., 5000 or 139).

Volumetric WeightThe "theoretical" weight of a package based on its size, charged if higher than actual weight.

Chargeable WeightThe final weight used on the invoice (Max of Actual vs Volumetric).

Frequently Asked Questions

For DHL Express, the standard volumetric divisor is 5000 when measuring in centimeters (L x W x H / 5000 = kg). In inches, it is 139 (L x W x H / 139 = lbs). Some legacy economy services may use 6000, but 5000 is the global industry standard.

Formula: Length (cm) × Width (cm) × Height (cm) ÷ 5000. Example: A box 50x40x30 cm. 50×40×30 = 60,000. 60,000 ÷ 5000 = 12 kg volumetric weight.

The shift from 6000 to 5000 aligns revenue with aircraft density. Modern aircraft have limited volume. A ratio of 1:5000 (1 cbm = 200 kg) better represents the density required for profitability than the older 1:6000 (1 cbm = 167 kg) standard.

Yes. DHL rounds every measurement up to the nearest whole number (cm or inch) BEFORE multiplying. 10.2 cm becomes 11 cm. This can significantly impact the final chargeable weight.

Typically, yes. DHL Express (courier) uses 5000 (1:200 density). DHL Global Forwarding (air freight cargo) often uses 6000 (1:167 density), which is cheaper for shippers. Always check your specific contract.
