How to Negotiate Corrugated Packaging Contracts in 2026

The Negotiation Context

Corrugated converters are currently seeking 10-15% price increases citing OCC and energy input cost pressures. PackIndex data tells a more precise story — one that gives buyers a specific, defensible counter-position.

What the Data Actually Shows

The headline is accurate. But the composition matters. OCC is 42-45% of corrugated BOM, not 100%. Energy is 15-18%. The blended cost increase is 8-11% — not 13-15%.

The Three Arguments

Argument 1: The BOM-weighted increase "Our analysis using PackIndex BOM weights shows blended input cost increase of 9.2%. We accept an 8-10% adjustment, not 12-15%."

Argument 2: The energy lag "NBP gas eased 4.1% in February. Mill energy contracts locked at Q4 peak roll off in Q2. We expect an energy component reversal by Q3 — we want that reflected in the contract."

Argument 3: Index-linkage going forward "Rather than negotiate a fixed price annually, we propose PackIndex CORR index-linked pricing with a ±8% cap/collar, reviewed quarterly. This removes the annual negotiation overhead and protects both sides."
