Kraft paper prices surge 25% in ten weeks squeezing Indian corrugated converters

A rapid escalation in raw material costs

The Indian corrugated packaging industry is facing a severe margin squeeze as kraft paper prices have surged by approximately 25% since mid-July 2026. The South India Corrugated Box Manufacturers' Association (SICBMA) has raised the alarm over the unprecedented speed of these hikes, reporting seven consecutive price revisions in just ten weeks. The cumulative increase amounts to roughly ₹8,000 per tonne, with the latest revision taking effect on October 1, 2026. If this trajectory continues, the association warns that the total increase could approach 35%.

This sharp inflation is primarily driven by upstream pressures. The depreciation of the Indian Rupee against the US Dollar has significantly increased the cost of importing essential papermaking inputs, including wood pulp, recovered fiber, and chemicals. Consequently, domestic kraft paper prices have jumped from around ₹30,000-₹31,000 per tonne to ₹35,000-₹38,500 per tonne. For converters, who operate on notoriously tight margins, absorbing these costs is becoming unsustainable.

The working capital trap

Beyond the immediate procurement costs, the current cycle is creating a severe working capital crisis for corrugated box manufacturers. Converters are caught between shorter credit periods from paper mills and slower collections from downstream customers. This liquidity squeeze is further exacerbated by India's Goods and Services Tax (GST) structure. Manufacturers pay 18% GST on kraft paper and other inputs, but sell corrugated boxes at a 5% GST rate. This disparity leads to an accumulation of input tax credits, locking vital cash within the business while refunds are delayed.

In response to these pressures, corrugated box manufacturers in South India have announced a 20% increase in box prices. However, this hike falls short of the 25% raw material cost surge, indicating that converters are still absorbing a portion of the shock. SICBMA has urged customers, particularly in sectors like garments and apparel, to accept pricing based on prevailing raw material costs and to clear outstanding payments within 30 days to ensure supply continuity.

Global context and strategic implications

The situation in India mirrors broader global tensions in the containerboard market. Major producers worldwide, including Packaging Corporation of America, International Paper, and Smurfit WestRock, have also announced significant price increases in late 2026, citing capacity constraints, recovered paper costs, and energy expenses. In this volatile environment, scale, regional diversification, and backward integration are becoming critical competitive advantages for packaging companies.

For the Indian market, the current crisis highlights the structural asymmetry of the value chain, where converters act as the transmission mechanism for upstream cost shocks. As the industry navigates these turbulent waters, greater payment discipline and multi-vendor sourcing strategies will be essential to mitigate financial risks and ensure the stability of the packaging supply chain.

The resilience of the Indian corrugated sector is being tested, but this crisis could act as a catalyst for necessary structural adjustments and consolidation, ultimately leading to a more robust and financially disciplined industry. How long can independent converters sustain this working capital pressure before we see a wave of strategic acquisitions in the region?
