I need to add new packing method one rate in fedex packing serive in magento1. Any suggestion would be appreciated.

I had a reply from fedex saying As per the Developer Resource Guide- To specify FedEx One Rate Pricing Option in the Web Service Transaction, perform the following steps:

  1. Specify the "FEDEX_ONE_RATE" ShipmentSpecialService.

  2. The FedEx Packaging Types that are valid/available with the One Rate pricing option are the following:

  3. Specify a U.S. origin and a U.S. destination.

Note: Intra-Hawaii shipments are not allowed for One Rate pricing.

  1. Specify one of the following FedEx Express services:

    • 2_DAY
    • 2_DAY_AM

Note: Web Services clients can request both One Rate and weight-based (non-One Rate) rates in a single RateRequest by specifying "FEDEX_ONE_RATE" as a ServiceOptionType in the RateRequest.variableOptions.


As I understood you need to add custom container type for that you need to rewrite Mage_Usa_Model_Shipping_Carrier_Fedex in your module.

I am mentioning changes that you need to done after rewrite:

 protected $_customizableContainerTypes = array('YOUR_PACKAGING',

Need to update following portion in getcode() method:

'packaging' => array(
    'FEDEX_ENVELOPE' => Mage::helper('usa')->__('FedEx Envelope'),
    'FEDEX_PAK'      => Mage::helper('usa')->__('FedEx Pak'),
    'FEDEX_BOX'      => Mage::helper('usa')->__('FedEx Box'),
    'FEDEX_TUBE'     => Mage::helper('usa')->__('FedEx Tube'),
    'FEDEX_10KG_BOX' => Mage::helper('usa')->__('FedEx 10kg Box'),
    'FEDEX_25KG_BOX' => Mage::helper('usa')->__('FedEx 25kg Box'),
    'YOUR_PACKAGING' => Mage::helper('usa')->__('Your Packaging'),
    'one_rate' => Mage::helper('usa')->__('one Rate')

'containers' => array('YOUR_PACKAGING','one_rate'),         

After that you need to change getContainerTypes method:

return array('YOUR_PACKAGING' => Mage::helper('usa')->__('Your Packaging'),
                'one_rate' => Mage::helper('usa')->__('one Rate'));

I hope this will help you. Please let me know if you have queries.
