Crate Weight Volume Density Shipping Class Classifier

Separate gross shipping density from payload-per-external-volume density before caller class mapping; not carrier NMFC classification, dangerous-goods status or packing safety.

Description

Shipping density includes crate tare, while payload density excludes it.

Shipping density includes crate tare, while payload density excludes it. Both use the same external geometric volume.

Separate gross shipping density from payload-per-external-volume density before caller class mapping; not carrier NMFC classification, dangerous-goods status or packing safety.

When to use Crate Weight Volume Density Shipping Class Classifier

Use this tool to separate gross shipping density from payload-per-external-volume density before caller class mapping; not carrier NMFC classification, dangerous-goods status or packing safety.

Prepare the collection, exposure, scheduling or financial records required for this calculation. Keep row order and the declared units consistent.

How to use Crate Weight Volume Density Shipping Class Classifier and understand its results

Prepare the collection, exposure, scheduling or financial records required for this calculation. Keep row order and the declared units consistent.
Enter crateGrossMassKg, crateOuterDimensionsM, callerDensityClassLowerEdgesKgPerM3, declaredTareKg using the field table and calculation rules, then run the tool.
Read grossCrateDensityKgPerM3, netPayloadDensityKgPerM3, callerGrossDensityClassCode. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
crateGrossMassKg	Crate gross mass kg	number	Required
crateOuterDimensionsM	Crate outer dimensions m	list of number	Required
callerDensityClassLowerEdgesKgPerM3	Caller density class lower edges kg per m3	list of number	Required
declaredTareKg	Declared tare kg	number	Required

Use three positive dimensions, nonnegative gross and tare with tare no greater than gross. Assign a zero-based gross-density class using 2–128 increasing covering lower edges; equality starts the new class.^[1]

gross density = gross mass/external volume; payload density = (gross − tare)/volume

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
grossCrateDensityKgPerM3	Gross crate density kg per m3	number
netPayloadDensityKgPerM3	Net payload density kg per m3	number
callerGrossDensityClassCode	Caller gross density class code	number

Limitations and assumptions

Caller classes are not carrier NMFC, dangerous-goods or packing-safety determinations.

Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Travel Frame Size Oversize Surcharge Trigger Checker: Compare packed outer frame dimensions including both face allowances with caller declared transport axis limits; no implicit axis rotation, shipping surcharge amount or safe packaging approval. For a complementary task, use Box List Item Count per Linear Metre Estimate Calculator: Expand heterogeneous counted box-list inventory and measured widths to actual item density per linear metre; not a fixed box conversion or universal item density.
