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.

Days since delivery (d)

Days elapsed since delivery.

Window days (d)

Notice window stated by the applicable carrier terms or rule; the default is for planning only.

Check elapsed time against a configurable concealed-damage notice window. Confirm the applicable carrier contract, tariff, bill of lading, and law rather than treating the five-day planning default as a universal deadline. 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]

Within window

Whether a concealed damage report is still timely.

Days left (d)

Days left to report (negative once the window has closed).

• 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.

• Order to Door Response Time

  Measure elapsed hours between order placement and doorstep delivery and check the result against a delivery-promise target in hours.

• Additional Handling Fee Trigger Checker

  Check a rectangular parcel against configurable longest-side, second-longest-side, actual-weight, and length-plus-girth thresholds; packaging and service-specific rules are outside this numeric screen.

• 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.
