Parcel Packing Method #

The plugin and built-in box-packer require that your non-virtual products have weights and dimensions set. More at: Adding Dimensions and Weights to Products for Shipping.

There are two packing methods with PostNL, and each affects the parcels you send:

  • Per Item — Each physical item in your cart is sent individually. Quotes for all items are combined for the final cost.
  • Pack into Boxes — Items are packed into pre-defined boxes and sent for a quote. We recommend this option. See Box-Packing below for more information on this.

Box-Packing #

The box packer included with this shipping method allows you group items into packages with height, width, length, and max-weight provided by PostNL. The packing is mainly volume-based but also considers item size. The box packer is volume-based. This provides good results in most cases, but will never be as accurate as a real person packing a box (see BIN Packing Problem). It is important you understand that packing results are as accurate as they can be and any anomalies should be accepted.

How the calculation works #

The packer does the following:

  1. Finds boxes which fit the items being packed (uses H x W x D).
  2. Packs all fitting items into boxes (using volume).
  3. The largest box which fits 100% of items is used *or* use the highest % packed box, and then pass unpacked items back (and repeat the process)
  4. Unpackable items are packed alone, using the item dimensions.
  5. All packed boxes are returned.

Usage #

Customers can get quotes, after inputting their address, from two places:

  • Cart page – using the shipping calculator
  • Checkout page – filling in the shipping and billing forms

Rates can be selected by customers as usual.

Troubleshooting #

No rates returned/no rates available #

  1. Enable debug mode (WooCommerce > Settings > Shipping > PostNL) to see debugging information on the cart page. This will often reveal the problem.
  2. Check your products have sizes and weights set – without this the calculation cannot be performed.
