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.

Declared value

Value declared to customs in currency units.

Gross weight (kg)

Gross weight in kilograms.

Invoice quantity

Units shown on the commercial invoice.

Invoice value

Commercial invoice total in currency units.

Net weight (kg)

Net weight in kilograms.

Shipped quantity

Units actually shipped per the packing list.

Value tolerance (%)

Allowed value difference in percent of invoice value.

Cross-check customs declared value against invoice value within a percent tolerance, shipped against invoiced quantities, and net against gross weights before lodging an entry. 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]

Fully consistent

True when no consistency issue was flagged.

Issues

Plain-language list of detected inconsistencies.

Quantities match

True when invoiced and shipped quantities match.

Values match

True when declared value is within tolerance of invoice value.

Weights plausible

True when net weight does not exceed gross weight.

• 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.

• Battery UN3480 SoC 30 Percent Checker

  Check lithium-ion cells and batteries shipped standalone under UN 3480 against the IATA requirement of a state of charge not exceeding 30 percent of rated capacity.

• Certificate of Origin FTA Threshold Check

  Screen achieved regional value content against an agreement-specific threshold and optional shortfall allowance. Only use the allowance when the applicable rule explicitly permits it in RVC percentage points; this calculation does not establish preferential origin by itself.

• Container Payload Weight Checker

  Sum cargo and packing material weights and check the total against a container or road-leg payload limit.
