Volumetric Weight Calculations by DTDC: Explained

Introduction: The Growing Challenge of Shipping Weight Discrepancies

E-commerce sellers in India are facing a persistent problem: shipping weight discrepancies. Many sellers often complain about courier overcharges, incorrect volumetric weight calculations, and disputes with courier companies. Manual errors, inconsistent weighing practices, and lack of transparent proof reports make the situation worse. Whether you are shipping through DTDC, Delhivery, Blue Dart, or Flipkart Smart Fulfilment, these challenges result in financial losses, wasted time, and unhappy customers.

In this blog, we will break down DTDC’s volumetric weight formula, show how it differs from other courier companies, and explain how sellers can ensure compliance. Finally, we’ll introduce Scandim360—a smart automated dimensioning and volumetric weight system designed to eliminate disputes, save costs, and bring accuracy to e-commerce logistics.

Why Weight Discrepancy Matters for E-Commerce Sellers

Weight discrepancies are not a minor issue—they directly impact profitability and trust. Here’s why this problem matters:

• Financial Losses: Sellers end up paying higher shipping charges when couriers recalculate weights manually or incorrectly.

• Disputes with Couriers: Without proof reports, sellers have no strong ground to contest overcharges.

• Customer Dissatisfaction: Higher shipping costs often get passed on to customers, leading to poor satisfaction.

• Lack of Transparency: Different couriers use slightly different volumetric formulas, leaving sellers confused.

• Wasted Time: Hours are spent disputing charges, instead of focusing on sales and business growth.

DTDC’s Volumetric Weight Formula

DTDC, like most courier companies, uses volumetric weight as the basis for shipping charges when the package is bulky but lightweight.

Formula Used by DTDC:

This means that a package measuring 50cm x 40cm x 30cm would be:

If the dead (actual) weight is only 7 kg, DTDC will still charge for 12 kg, as volumetric weight is higher.

How DTDC Differs from Competitors

• Blue Dart / FedEx: Use a divisor of 5000 (same as DTDC).

• Delhivery: Uses a divisor of 4000 for air shipments, making volumetric charges higher.

• India Post / Some Regional Couriers: Still rely heavily on dead weight, but may add surcharges for larger parcels.

This creates confusion for sellers who ship with multiple partners. Ensuring compliance with each courier’s formula is critical.

The Problem with Current Practices

• Manual Weighing: Staff manually measure packages with tape measures, often leading to small but costly errors.

• Courier Recalculations: Even after sellers record dimensions, couriers often recheck at warehouses and update charges.

• No Proof Reports: Sellers cannot prove their measurements in disputes with courier companies.

• Operational Errors: Wrong entries lead to incorrect billing, penalties, or delayed shipments.
