Definition & Explanation

Unlike fixed base freight rates, rate adjustment programs for reefer carriers are contractual mechanisms that allow periodic or automatic rate revisions when operating costs shift. Adjustments are typically triggered by changes in published fuel or energy price indices—bunker surcharges being the most common reference—or by pre-agreed review intervals. For refrigerated container operators, these programs are especially relevant because reefer units consume significantly more power than dry containers, making margins more exposed to energy price volatility. From the shipper's perspective, index-linked adjustments offer greater predictability than unilateral general rate increase (GRI) announcements, since the adjustment formula is agreed in advance. The key distinction from GRIs is that rate adjustment programs are bilaterally negotiated and tied to measurable benchmarks.
