Why Dry Ice Is Becoming the Go-To Solution for Cold Chain Logistics in 2026

Temperature-controlled shipping is not new. The question of how to keep perishables cold during transport has been part of logistics since the first ice trade routes were established in the 1800s. What is relatively new is the scale, the speed expectations, and the product categories now moving through cold chain infrastructure.

Dry ice has become a central part of that equation. Where it was once a specialty option reserved for pharmaceutical transport and high-value perishables, it has moved toward operational standard across food delivery, biotech shipping, and a widening range of last-mile logistics.

What changed in last-mile cold chain

Two converging trends

Two things happened in parallel over the last five years. Direct-to-consumer food shipping expanded dramatically. And pharmaceutical cold chain requirements tightened, driven in part by the distribution demands exposed during COVID-19 vaccine deployment.

Both trends created demand for temperature maintenance that didn’t depend on refrigerated truck infrastructure. Direct-to-consumer food companies can’t put every delivery on a refrigerated truck. The economics don’t work at the order sizes and geographic spread involved. Dry ice in insulated packaging fills the gap, maintaining temperature for the duration of transit without any active power source.

Pharmaceutical requirements

The pharmaceutical side is more regulated but runs on similar logic. Cold chain integrity documentation is required for many drug categories, and dry ice provides a passive temperature control solution with a long enough duration to cover most domestic shipping windows.

For biologics and vaccines that require ultra-cold storage in the minus-seventy-eight-degree Celsius range, dry ice is often the only practical option outside of liquid nitrogen.

Food delivery applications

Meal kits and premium e-commerce

The growth of meal kit services and premium food e-commerce has pulled dry ice into everyday logistics at a scale that didn’t exist a decade ago. A company shipping wagyu beef or fresh pasta to residential addresses needs to maintain temperature from the distribution center to the doorstep, across an unpredictable delivery window.

Dry ice works for this because it’s dense, doesn’t produce liquid as it sublimates, and can be sized to match the expected transit time. A two-day ground shipment requires a different quantity calculation than an overnight delivery. Suppliers and logistics teams have developed standard formulas for common routes and shipping scenarios.

High-value categories

Seafood and proteins drive the highest volume demand. Specialty produce is also a growing category, particularly premium mushrooms, truffles, and live shellfish, where temperature excursions translate directly to quality loss. The same dry ice infrastructure that handles these categories also supports specialty confections like premium chocolates and ice cream, where even minor melting creates a product presentation problem.

California and Colorado as distribution hubs

California is the largest agricultural state in the country and one of the leading states for food manufacturing, life sciences, and business-driven pharmaceutical production.

Regional suppliers like AdChem Gas dry ice delivery serve businesses across California — with distribution hubs in the East Bay and San Bernardino — providing food-grade dry ice in rice or pellet form, with delivery coordination designed around commercial production and shipping schedules.

Pharmaceutical and biotech cold chain

Stricter requirements

The requirements in pharmaceutical shipping are stricter than in food. Temperature excursion logs are part of regulatory documentation for many drug categories. Chain of custody matters. And the consequences of a cold chain failure are measured in both product loss and regulatory exposure, not just a disappointed customer.

Dry ice used in pharmaceutical shipping has to meet purity standards that differ from food service applications. The documentation requirements are more involved. Suppliers who serve this segment have to maintain traceability and certifications that wouldn’t be required for event or food service customers.

Air transport standards

The International Air Transport Association maintains standards for dry ice shipment by air, including packaging requirements and quantity limits per passenger aircraft. Ground transportation regulations differ by cargo classification and quantity. Businesses new to pharmaceutical cold chain shipping typically work with a logistics specialist or supplier to ensure their packaging and documentation meet applicable standards before going live.

The infrastructure behind dry ice supply

How it is made

Dry ice is produced by compressing and cooling carbon dioxide until it liquefies, then allowing it to expand rapidly and solidify. It’s manufactured at facilities that produce CO2 as a byproduct of industrial processes, including ammonia production, fermentation, and natural gas processing.

Supply chain vulnerabilities

This means dry ice supply is tied to industrial CO2 production, which can create regional supply constraints when industrial output changes. The COVID-19 period exposed some of these dependencies when CO2 supply was disrupted by shutdowns at food processing and industrial facilities. The logistics industry took note.

Regional suppliers who have their own CO2 sourcing relationships and storage capacity can buffer against short-term supply disruptions in ways that spot-market buyers cannot. For businesses that have incorporated dry ice into standard operations, supply reliability is not a minor consideration.

What logistics teams are watching

The next phase of cold chain development is likely to involve more precise tracking and documentation of temperature throughout the shipping process. IoT temperature loggers embedded in packaging already exist, and their cost has dropped enough that inclusion in higher-value shipments is increasingly common.

Dry ice will remain the passive cold source in most of these systems, even as the documentation layer around it grows more sophisticated. The fundamental physics haven’t changed: sub-zero temperature, no liquid residue, no power requirement, and a sublimation rate that can be calculated in advance.

For an industry that values predictability, those characteristics matter more in 2026 than they did before last-mile cold chain became a competitive necessity.
