India's corrugated box industry is the major player behind packaging for e-commerce, pharma, FMCG, electronics sectors, etc. The Eastern India Corrugated Box Manufacturers’ Association has cited around 20,000 MSME units operating in the corrugated box packaging sector. GST on corrugated boxes in India has a direct impact on their working capital and profitability.
Among the strong growth, most manufacturers experience the problem of working capital blockage mainly due to the Inverted Duty Structure (IDS) under Goods and Services Tax (GST). Inputs such as kraft paper and adhesives are liable to 18% GST whereas finished corrugated boxes are only 5% GST. This disparity results in regular buildup of unused ITC and thus impairs the cash flow of the business directly.
If you are a corrugated box manufacturer in India, this guide will help you understand:
- Why GST refund is critical for your business
- GST rate and HSN codes for corrugated boxes
- When GST refund is applicable
- How to claim the refund step by step
- Common mistakes to avoid
- How to speed up approval
Why is GST Refund important for Corrugated Box manufacturers?
GST refund is not just a compliance matter for corrugated box manufacturers, it helps them to regulate their working capital, increase liquidity and expansion capabilities.
Under GST, corrugated box industry commonly faces mismatched tax rate on their input and output. The current GST rate on corrugated boxes (finished goods) is 5% whereas inputs like kraft paper, adhesives and corrugated rolls attract 18% - this mismatch causes continuous accumulation of unutilised ITC. It leads to working capital blockage, which further blocks cash flows and limits funds available for purchasing raw materials or meeting operating expenses.
The Eastern India Corrugated Box Manufacturers Association (EICBMA) has raised serious concerns that the Inverted Duty Structure has put over 20,000 MSMEs at risk of closure. So, proper planning and compliance is necessary for faster GST Refunds.
Types of GST Refund Available
Under Section 54 of the CGST Act, a registered taxpayer can claim a GST refund in specific situations.
- Refund of accumulated ITC (Inverted Duty Structure)
- Refund on zero-rated supplies (Exports)
- Refund of excess balance in electronic cash ledger
- Refund of wrong tax payment (CGST/SGST instead of IGST)

This gap between 18% GST on corrugated box inputs and 5% on output is exactly what creates the IDS refund opportunity for manufacturers.
Rate Update from 22 September 2025: Cartons, boxes and cases under HSN 4819 10 and 4819 20, including specified corrugated and non-corrugated paper or paperboard products, attract 5% GST.
Common paper inputs under headings such as 4804 and 4808 generally attract 18%, subject to exact classification. This rate difference may lead to unutilised ITC eligible for IDS refund, subject to Section 54(3).
When GST Refund is applicable?
For corrugated box manufacturers, following cases are applicable in general:
1. Inverted Duty Structure
When the raw material is purchased at a tax rate higher than that of finished good, it is known as Inverted Duty Structure under GST. For corrugated box manufacturers, inputs like kraft paper, duplex board, adhesives, and inks are taxed at 18% while finished corrugated boxes are taxed at 5% - this difference results in accumulation of unutilised ITC.
Eligible inputs include kraft paper and duplex board, adhesives and starch, corrugated rolls and duplex sheets, and inks and packaging tape. Note: Capital goods ITC (machinery) and services ITC do NOT qualify under IDS refund.
Refund can be claimed on account of inverted duty structure under Section 54 of CGST Act, Rule 89(5).
2. Export of Corrugated Boxes
Exports are treated as zero rated supply under GST and it can be of two ways:
- Export with payment of tax (refund of IGST paid via shipping bill)
- Export under LUT without payment of tax (refund of accumulated ITC)
Eligible zero-rated refund claims may qualify for provisional refund of up to 90% of the admissible amount, subject to Section 54(6), Rule 91 and applicable eligibility, risk and verification conditions.
Documentation Required
The following should be ensured before filing of GST Refund:
- GSTR-1 & GSTR-3B reconciliation
- ITC reconciliation with GSTR-2A, 2B
- HSN-wise inward and outward supply data
- Export invoices and shipping bills (in case of exports)
- LUT copy (if exporting without payment of tax)
- Purchase register classified into Input Goods, Input Services, Capital Goods
- Applicable declaration/certificate under Rule 89. For an eligible IDS refund under Section 54(3), a CA/CMA certificate is not required merely because the claim exceeds ₹2 lakh.
- Bank account validation on GST portal
Any mismatch between GSTR-1, GSTR-3B, and shipping bill data may result in deficiency memo (RFD-03).
Time Limit for Filing Refund
A GST refund application is generally required within two years from the applicable “relevant date” under Section 54.
For IDS refund, the relevant date is the due date for furnishing the Section 39 return for the period in which the claim arises. For export refunds, the relevant date depends on the applicable export circumstances.
Common Reasons for Refund Delays/Rejection
Common causes of refund delays or disputes include data mismatches, calculation errors and incomplete reconciliation.
- Lapse of Time Limit: Filing refund claim after the prescribed 2-year time limit leads to rejection.
- ITC mismatch in GSTR: Eligible ITC claimed in GSTR-3B should be supported by applicable records, including credits communicated in GSTR-2B. Unexplained mismatches may lead to scrutiny.
- Non-reconciliation of GSTRs: A small mismatch between GSTR-1 and 3B can hold the refund claim.
- HSN code mismatch: Mismatch in HSN codes between inward and outward supplies can trigger scrutiny and deficiency memos.
- Ineligible ITC included: Inclusion of ineligible ITC like capital goods, services, or blocked credit under Section 17(5) can lead to rejection.
- Errors in shipping bill data: Mismatch in shipping bills, invoice values, or LUT Compliance can trigger deficiency memos.
- Inverted duty structure miscalculation: Miscalculation of refund by prescribed Rule 89(5) formula leads to refund hold.
For corrugated box manufacturers, these points are critical to avoid any delay or rejection.

Why Corrugated Box Manufacturers Should Avoid DIY Refund Filing
IDS refund claims require accurate calculation, reconciliation and supporting documentation. Filing refund without proper planning and understanding can lead to Departmental queries and scrutiny, ultimately delaying the refund process.
Some reasons why DIY Refund Filing is risky:
- IDS Refund Scrutiny: Corrugated box units frequently claim inverted duty refunds, which may be examined by GST officers. Even minor calculation errors under Rule 89(5) can trigger notices.
- Large ITC Accumulation: Manufacturers purchase kraft paper, adhesives, corrugated rolls and packaging material which is mostly taxed at 18% leading to heavy ITC buildup.
- Risk of Deficiency Memo (RFD-03): Wrong HSN, mismatch in returns, ineligible ITC can end up in issue of RFD-03.
- Impact on Cash Flow: Businesses struggle to maintain healthy cash flow when their ITC gets blocked. This affects vendor payments, employee salaries and business expansion.

Refund of Stuck Balance in Electronic Credit Ledger
In corrugated box manufacturing industries, heavy investments are done in capital goods like corrugating machines, die-cutting machines, printing machines, conveyor systems, etc. and various services are also taken for running the business. The ITC on these goods and services is not generally allowed under inverted duty structure and results in high accumulation in Electronic Credit Ledger but we help in strategic structuring which can improve ITC utilization.
We analyse capital goods ITC position and provide strategies, do proper ITC planning and set-off structuring which helps in converting it into tax efficiency. From verifying credit ledger balances to preparing refund applications with proper classification of capital goods and services, we ensure full compliance and faster processing.
