Corrugated boxes now attract 5% GST (under GST 2.0, effective 22 Sep 2025), while raw materials like kraft paper and adhesives remain at 18%. This 13% gap creates an Inverted Duty Structure (IDS), allowing manufacturers to claim GST refunds under Section 54 of the CGST Act.
GST Rate on Corrugated Boxes (2026)
From 22 September 2025, corrugated boxes under HSN 48191010 attract only 5% GST (CGST 2.5% + SGST 2.5%, or IGST 5%). This reduction significantly impacts working capital for over 20,000 MSME manufacturers across India.
Current GST Rates Input vs Output
Note: Always verify current rates on cbic-gst.gov.in before filing returns.
What is Inverted Duty Structure (IDS)?
Inverted Duty Structure occurs when GST on inputs is higher than GST on the finished product.
For corrugated box manufacturers:
- Inputs (kraft paper, adhesives, corrugated rolls, inks) are taxed at 18%
- Output (finished corrugated boxes) is taxed at only 5%
This 13% gap causes unused Input Tax Credit (ITC) to accumulate every month in your Electronic Credit Ledger, blocking working capital that could be used for raw materials, vendor payments, or business growth.
Without claiming GST refunds, manufacturers face inability to purchase raw materials in bulk, delayed vendor payments, stunted business expansion, and competitive disadvantage.
Important
Under Section 54 of the CGST Act, claiming this refund is your legal right not a government favor. It is your money, blocked due to a tax rate mismatch.
How to Calculate Your Refund Rule 89(5) Formula
Formula
Refund = (Turnover of Inverted Rated Supply × Net ITC ÷ Adjusted Total Turnover) − Tax Payable on Inverted Rated Supply
Worked Example ABC Corrugators Pvt Ltd (Monthly)
Calculation: (₹10,00,000 × ₹1,80,000 ÷ ₹12,00,000) − ₹50,000 = ₹1,50,000 − ₹50,000 = ₹1,00,000
Kraft paper, duplex board, corrugated rolls, adhesives, printing inks, packaging tape.
ITC to Exclude
Capital goods (machinery), input services (rent, legal fees), reverse charge payments, blocked credits under Section 17(5).
7 Common Reasons for Rejection And How to Fix Them
Note
Most rejections are technical, not eligibility issues. Correct the specific error and refile.
⚠️ 2-Year Filing Deadline Don’t Lose Your Refund
Under Section 54 of the CGST Act, the GST refund application must be filed within 2 years from the relevant date. For IDS refunds, the relevant date is the last date of filing for the quarter in which the refund claim arises.
What this means practically:
- If your ITC accumulated in Q1 FY2024-25 (Apr–Jun 2024), the deadline to file is June 2026.
- Missing this deadline means permanently losing that refund there is no extension.
- File quarterly rather than waiting to accumulate this reduces risk of deadline misses.
- Even if your CA or consultant delays, the legal responsibility lies with you as the taxpayer.
Many manufacturers lose lakhs simply by missing the 2-year window. Set a calendar reminder every quarter to review your ITC balance and file promptly.
Post-Filing Journey What Happens After RFD-01?
Most manufacturers don’t know what happens after they submit RFD-01. Here is the complete post-filing journey:
If you receive RFD-03 (deficiency memo), do not ignore it. You have only 7 days to respond. Failure to respond results in automatic rejection and you must refile from scratch.
Industry Context Why This Matters
The corrugated box industry in India is dominated by MSMEs, with over 20,000 small and medium manufacturers spread across states like Maharashtra, Gujarat, Tamil Nadu, West Bengal, and Delhi-NCR. The Eastern India Corrugated Box Manufacturers Association (EICBMA) has formally raised concerns with the GST Council that IDS is putting thousands of these units at risk.
Key industry facts that highlight the urgency:
- Average corrugated box manufacturer carries 12–15% of monthly turnover as blocked ITC.
- A manufacturer with ₹50 lakh monthly turnover could be losing ₹6–7.5 lakh every month to IDS.
- Many MSMEs are unaware they can claim industry estimates suggest less than 30% of eligible units file for refund.
- The CBIC has issued multiple circulars (Circular No. 135/05/2020-GST and related) clarifying IDS refund eligibility for manufacturers.

Frequently Asked Questions (FAQs)
What GST rate applies to corrugated boxes in 2026?+
Corrugated boxes (HSN 48191010) attract 5% GST under GST 2.0, effective 22 September 2025. Since raw materials like kraft paper and adhesives are still taxed at 18%, manufacturers can claim a GST refund under the Inverted Duty Structure (IDS).
Can I claim a GST refund for previous quarters?+
Yes, you can file a refund claim for any past period within 2 years from the relevant date. Filing quarterly is recommended to avoid missing the Section 54 CGST Act deadline.
My GSTR-3B has errors. Can I still claim the ITC refund?+
Not directly. First correct the errors via an amendment return. Any mismatch between GSTR-1, GSTR-3B, and GSTR-2B will trigger an RFD-03 deficiency memo or outright rejection of your RFD-01 application.
How long does a GST refund on corrugated boxes actually take?+
Officially 60 days from a complete RFD-01 application. In practice, most IDS refund claims are processed within 45 to 75 days. Export refunds under LUT are faster, with 90% provisional credit within 7 working days.
Do I need a CA to file RFD-01?+
No, any GST-registered manufacturer can file RFD-01 independently. However, a CA certificate becomes mandatory when the refund claim exceeds ₹2 lakhs, especially given the complexity of the Rule 89(5) calculation.
What is the difference between an IDS refund and an export GST refund?+
Both use Form RFD-01, but the process differs. IDS refund is calculated using the Rule 89(5) formula with HSN-wise purchase and sales registers. Export refund under LUT requires shipping bills and export invoices. If eligible for both, file separate applications.
Which officer processes my GST refund application?+
Your RFD-01 is handled by the Jurisdictional GST Officer linked to your GSTIN, either Central Tax or State Tax authority. Check your officer details at gst.gov.in > My Profile > Jurisdictional Details. Claims above ₹50 lakhs may be escalated to a senior GST audit team.
Is GST applicable on corrugated boxes?+
Yes. Under GST 2.0, corrugated boxes under HSN 48191010 are taxed at 5% (CGST 2.5% + SGST 2.5%). The rate was 12% from July 2024, and 18% from October 2021 to July 2024.
What is the HSN code for corrugated boxes?+
The HSN code for corrugated boxes is 48191010 at 5% GST. Non-corrugated cartons fall under HSN 48192010 at 12%. Corrugated sheets and rolls are classified under HSN 48081000 at 18%. Always use the correct 8-digit HSN code, as mismatches are a leading cause of refund rejection.
What is the GST rate on corrugated sheets?+
Corrugated sheets and rolls (HSN 48081000) attract 18% GST. Since the finished corrugated box is taxed at only 5%, this gap is the core reason behind the Inverted Duty Structure refund opportunity for manufacturers.
What happens if my GST refund application is rejected?+
Rejection is not permanent. Most IDS refund rejections are due to documentation errors, not ineligibility. Correct the specific issue and refile. If you receive RFD-03, respond within 7 days. For an unfavorable RFD-06 order, appeal to the GST Appellate Authority within 3 months.
Can corrugated box exporters claim GST refund under LUT?+
Yes. Manufacturers exporting under a Letter of Undertaking (LUT) without paying IGST can claim a full Input Tax Credit refund under Section 54 of the CGST Act. A 90% provisional refund is granted within 7 working days of RFD-01 filing, with the remaining 10% released after verification.
