Use this logistics calculation for a transparent shipment, inventory, warehouse, customs, packaging, carrier, or service-level estimate when the governing units and business rules are explicit.

Setpoint

Requested container setpoint in degrees Celsius.

Deep-freeze max

Ceiling at or below which cargo counts as deep-frozen, in degrees Celsius.

Freeze max

Ceiling below which cargo counts as frozen, in degrees Celsius.

Classify a reefer setpoint as deepFrozen (at or below the ceiling, default -18 C), frozen (below zero) or chilled (zero or warmer); both ceilings are inputs. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Mode

Temperature-controlled transport mode for the setpoint.

• Carrier tariffs, customs rules, dangerous-goods requirements, hours-of-service rules, surcharges, port terms, dimensional divisors, and service definitions vary by jurisdiction, contract, date, mode, and commodity. A calculation is not a booking, classification, or compliance determination.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify current carrier and authority documents, retain shipment dimensions and timestamps, test boundary cases, and reconcile estimates against invoices and operational scans.

• Dim Divisor US-EU Comparison Lookup

  Compare volumetric weight for the same carton under a US express-style divisor (default 5000 cm3/kg) and an EU road-style divisor (default 3000 cm3/kg), both overridable from your tariffs.

• Slotting Velocity ABC Classifier

  Pareto-slot an item by its cumulative share of pick throughput: A up to the first boundary (default 80%), B to the second (default 95%), C beyond; boundaries are inputs.

• HS Code and Duty Rate Resolver

  Split a 6- to 10-digit HS or national tariff code into chapter, heading, and HS subheading, then resolve a supplied general or preferential ad-valorem rate. Rates are not inferred from the first two digits because the applicable tariff depends on the full classification, jurisdiction, origin, and date.
