Single Cargo Parcel

Enter the signed shipper/laboratory TML and actual moisture values. Cargo presets are descriptive only and never assign a legal cargo group or TML.

Cargo / commodity

Declared IMSBC group

Cargo parcel masstonnes.

Certified TML% by mass, wet basis.

Tested moisture content% by mass, wet basis.

Company planning buffer below TMLpercentage points. Company screen only, not an IMO threshold.

TML test agemonths since TML test.

Moisture sampling / test agedays before loading.

Significant rain / snow since MC sampling

Can-test observationA dry can test never proves TML compliance.

Cargo & IMSBC Basis

Cargo / commodity

Declared IMSBC group

Primary behavior concern

IMSBC code basis

TML test method

Certified TML% wet basis. Certified value controls.

FMP, if reportedOptional cross-check for methods where TML = 90% of FMP.

Company planning buffer below TMLpercentage points.

Bulk densityt/m³, optional context.

TML test agemonths.

Cargo composition / characteristics changed since TML test

Hold / Parcel Moisture Register

Each materially different parcel should stand on its own. Any failed parcel controls the acceptance signal. Parcel names are retained only on screen and are not sent in Tool Data.

Sampling & Moisture-Control Status

Sampling plan basis

Subsamples actually takenUsed only by stockpile-scale screen.

Significant rain / snow after sampling

Post-rain moisture confirmation

Loading / handling during precipitation

Approved precipitation procedure appliesCargo schedule and approved procedure still control.

Signed TML certificate providedApplicable appropriate-authority / recognized testing basis confirmed. Signed moisture-content declaration / certificate providedRepresents cargo condition presented for loading. Sampling / testing procedure approvedApplicable competent-authority procedure available. Testing entity / laboratory recognizedRecognition appropriate to the port / authority arrangement. Representative consignment sampling confirmedWet pockets, variable source and fine fractions addressed. Cargo available for ship / survey inspectionAccess to cargo, barges and sampling is not restricted. Separate parcel declarations used when non-uniformDrier cargo is not used to average a wetter parcel into compliance. Rain / water-ingress controls effectiveStockpile, barge and hatch precautions are implemented.

Rain / Water-Ingress Sensitivity

Sensitivity only. Calculated rainfall water can show how quickly headroom disappears, but it cannot replace re-sampling or laboratory testing after material moisture exposure.

Exposed cargo surface aream².

Rainfall depthmm.

Water retention / capture factor% user estimate.

Direct estimated water ingresst. If above zero, overrides area × rainfall calculation.

Field Observations & Stop-Loading Flags

Free water / pooling observedImmediate stop-and-investigate flag. Wet splatter / slurry-like material observedPossible excessive moisture or variable wet zones. Cargo flattening / fluid appearance observedPossible liquefaction or dynamic-separation behavior. Unexpected list / cargo shift during voyageUrgent operational hazard requiring ship-specific response.

Stop / Retest Commercial Exposure

Vessel demurrage / delay valueselected currency/day.

Expected stop / retest delayhours.

Independent survey / expert attendance

Independent lab / re-sampling cost

Additional operational / agency cost

Freight / cargo value at riskOptional context only.

Safety limitation: this tool does not authorize loading or carriage. The actual IMSBC cargo schedule, certified TML, representative moisture-content testing, shipper declaration, appropriate-authority procedures, port/flag requirements, independent survey advice and the Master's judgment control. A dry can test is only a field observation and never proves the cargo is below TML.
