Examples of Inverted Duty Structure in India

India’s Goods and Services Tax (GST) was introduced to streamline the country's indirect taxation system. While it brought uniformity, one of the persistent structural challenges has been the inverted duty structure (IDS).This refers to a situation where the tax rate on inputs is higher than the tax rate on finished goods, creating pressure on working capital and making manufacturing less competitive.

In this blog, we will explore real-world examples of inverted duty structures in India and how to claim inverted duty refund, highlighting the sectors most affected and how this impacts their overall operations.

What is Inverted Duty Structure?

Before diving into the examples, let’s quickly recap what inverted duty structure means in the context of GST:

It occurs when input goods (raw materials) are taxed at a higher GST rate than the output goods (final products).
This leads to an accumulation of Input Tax Credit (ITC) that cannot be fully utilized.
Though refunds are allowed under Section 54(3) of the CGST Act, the process can be slow and complicated.

1. Textiles and Apparels

One of the most cited examples of IDS is the textile industry:

Input (fabric, yarn, dyes): 12% to 18% GST
Output (readymade garments below ₹1,000): 5% GST

This discrepancy results in excess ITC and reduced profitability for small and medium enterprises (SMEs) in the sector. Although refunds are allowed, delays in processing impact working capital needs.

2. Footwear Industry

Another prominent example is footwear:

Input (raw materials like leather, adhesives): 18% GST
Output (footwear below ₹1,000): 5% GST

This pricing mismatch has made domestic manufacturing less viable compared to imports, which often come at zero or reduced duties under free trade agreements (FTAs).

3. Fertilizer Sector

Even the fertilizer sector, which is vital for agriculture, faces IDS:

Input (ammonia, phosphoric acid): 18% GST
Output (fertilizers like urea and DAP): 5% GST

This structure increases the cost burden for manufacturers and creates refund backlogs, indirectly affecting farmers through higher input costs.

4. Renewable Energy Industry

Input (solar modules, inverters, mounting structures): 18% GST
Output (solar power generation): Exempt

While the government has exempted output from GST to promote green energy, it has unintentionally created an IDS problem. Producers can't claim full ITC on capital goods and services used, reducing returns on investment.

5. Pharma and Healthcare Products

In pharmaceuticals:

Input (active pharmaceutical ingredients): 18% GST
Output (essential medicines): 5% or exempt

This mismatch leads to increased compliance requirements and capital blockage for pharmaceutical manufacturers, especially those producing life-saving drugs.

6. Electrical and Electronic Goods

Input (components like LED drivers, circuit boards): 18% GST
Output (LED bulbs under certain price): 5% GST

This has slowed down the push for affordable energy-efficient appliances, as manufacturers face pricing and profitability issues due to IDS.

Government Efforts to Address IDS

The GST Council has taken note of IDS and made changes periodically:

Moved some items from lower to higher slabs to align input-output tax rates
Allowed refunds in certain cases
Discussed rationalization in specific sectors during council meetings

However, structural changes are still awaited in sectors like textiles and fertilizers, where significant distortions remain.

Conclusion

Inverted Duty Structure, though unintended, has become a hurdle for many Indian industries. From textiles to renewables, the impact is seen in working capital pressures, slowed investment, and reduced competitiveness. Addressing these discrepancies is vital for boosting domestic manufacturing, especially under the “Make in India” initiative.

As the GST system matures, a rational and equitable duty structure that minimizes IDS issues is key to long-term industrial growth and tax compliance.
