Volumetric Weight Calculations by India Post: Explained

Introduction: The Hidden Cost of Shipping with India Post

For e-commerce sellers in India, shipping is one of the most critical parts of business operations. Whether you use India Post, private couriers like DTDC, Delhivery, or logistics aggregators such as Shiprocket, one recurring challenge stands out: volumetric weight calculations.

Many sellers expect to pay based on the dead weight of a parcel, but couriers often charge according to volumetric weight (the amount of space a package occupies). This often leads to weight discrepancy India issues, courier overcharges, and disputes.

Unfortunately, due to manual weighing errors or miscalculated dimensions, sellers frequently end up paying more than they should. If you’ve ever wondered why your small but bulky product cost so much to ship, volumetric weight is the reason.

In this blog, we’ll explain:

• What volumetric weight is and why India Post uses it

• How manual processes create weight disputes

• The financial and operational impact on sellers

• How Scandim360 provides an automated solution

• Real-world use cases and a comparison of manual vs. automated processes

What is Volumetric Weight?

Volumetric weight, also known as dimensional weight, is a pricing method used by couriers like India Post. Instead of charging only on the actual dead weight, they calculate charges based on:

Formula:

Volumetric Weight=Length×Breadth×HeightCourier DivisorVolumetric \ Weight = \frac{Length \times Breadth \times Height}{Courier \ Divisor}Volumetric Weight=Courier DivisorLength×Breadth×Height​

• If the volumetric weight is higher than the actual weight, couriers charge based on volumetric weight.

• India Post and private couriers use different divisors, which makes it even more confusing for sellers.

For example:

• Dead weight: 2 kg

• Dimensions: 40 × 30 × 30 cm

• Volumetric divisor: 5000

Volumetric Weight=40×30×305000=7.2 kgVolumetric \ Weight = \frac{40 \times 30 \times 30}{5000} = 7.2 \ kgVolumetric Weight=500040×30×30​=7.2 kg

👉 Even though the parcel weighs 2 kg, India Post may charge for 7.2 kg.

Why Does This Problem Matter?

Incorrect or unfair volumetric weight charges are not just a minor inconvenience — they can deeply affect business operations.

1. Financial Losses

Courier overcharges add up quickly. A difference of 2–5 kg per parcel can mean thousands of rupees lost every month, especially for high-volume sellers.

2. Constant Disputes

Sellers often raise tickets with India Post or aggregators to dispute charges, but without proof of measurement, most disputes fail.

3. Customer Dissatisfaction

Delays in resolving shipping costs or disputes can delay refunds or deliveries, leading to bad reviews and lost customers.

4. Lack of Transparency

India Post and other couriers rarely share detailed proof of their recalculations, leaving sellers with little recourse.

5. Wasted Time & Effort

Instead of focusing on sales and growth, sellers spend hours emailing courier support teams.

Current Practices: Where Things Go Wrong

Most sellers and warehouses still rely on manual weighing and measurement.

• Digital weighing scales are used for dead weight.

• Dimensions are measured with tape or scale.

• Volumetric weight is calculated manually.

• Declared values are then uploaded to courier portals.

However, once the parcel reaches India Post hubs, staff may recalculate dimensions and apply their divisor. The lack of a standardized, automated record means:

• Sellers cannot prove their declared weight was accurate.

• India Post charges based on their recalculation.

• Disputes drag on without resolution.

This is where automation is needed.
