With dangerous goods, the mass of the substance counts, not the weight of the parcel. Fulfillment 4 weclapp therefore calculates with the net weight of your weclapp items. For liquids, the density factor is added: it translates the LQ limit in liters into kilograms, a special feature of Fulfillment 4 weclapp. Back to the overview: Gefahrgut 4 weclapp.

Net weight: the basis of all dangerous goods data

  • Source: the standard net weight field on the weclapp item, not a custom additional field.
  • Per substance: net weight times quantity in the parcel, summed per UN number. The same item in several bill of materials line items counts once.
  • What for: points total (ADR points and the 1000-point rule), net quantity in the transport document and the dangerous goods data to DPD, Gebrüder Weiss and Dachser; for Dachser rounded to whole kilograms.
  • If it is missing: the item counts as zero. That is why an empty net weight is the most common stumbling block.

Density factor: reliably converting LQ limits in liters

For many liquids, the LQ limit per inner packaging is given in liters, but weclapp holds a weight. The density factor (g/ml, between 0.5 and 3.0) on the item closes this gap: liter limit times density gives the limit in kilograms, against which the app checks the net weight.

Example: cleaning agent of class 8, packing group II, 1.03 kg per bottle, density 1.03 g/ml. The limit of 1 liter corresponds to 1.03 kg, so the bottle may ship as LQ. Without a density factor it would have failed at the 1 kg limit.

The density factor only affects the LQ decision, not the points total or the label. More on LQ: Limited Quantities (LQ) from weclapp.

FAQ

Frequently asked questions

Do I have to maintain the density factor for every item?

No, only for liquids that are supposed to ship as LQ and whose limit is given in liters. Without a density factor, the app checks the net weight directly against the limit.

Where do I get the density?

Usually from the manufacturer's safety data sheet. Enter it in g/ml on the weclapp item.

Does the app count gross or net?

Net: net weight of the item times quantity, not the gross weight of the parcel.
