Surcharge % (%)

Total charge (USD)

Base charge plus surcharge.

• 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.
