# Delivery terms

Understand delivery terms and their impact on Customs Duty and Import Tax Advanced features.

**Element type: Required for Advanced Features**

**Endpoints used:** [CreateNexusParameters](https://developer.avalara.com/api-reference/avatax/rest/v2/methods/Nexus/CreateNexusParameters/), [TransactionParameterModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/TransactionParameterModel/), [TransactionLineParameterModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/TransactionLineParameterModel/)

If your integration is going to be certified against the Customs Duty and Import Tax Advanced features, then you must provide a way for users to specify the [Incoterms/delivery terms](/avatax-for-cdit/jqc1241943768908/ "Understand the rules for customs duties, taxes, shipping, and insurance in cross-border purchases.") associated with their company. AvaTax supports the following delivery terms:

-   `DDP`: Delivered Duty Paid
-   `DAP`: Delivered at Place

In addition, be sure that you recognize how the [Importer of record](/avatax-for-cdit/grx6505019624672/ "Understand the responsibilities of the importer of record in cross-border sales.") can affect delivery terms. Specifically, if the seller is not the importer of record, and the delivery terms are DDP, then the seller will be acting as the buyer's agent. The seller is also responsible for filing and remitting tax.

Specifying the delivery terms is done using the `DeliveryTerms` parameter during Nexus creation. This can also be overwritten in a transaction at either the line level or document level.

**Example**

```
"parameters":[
    {
        "name": "DeliveryTerms",
        "value": "DAP"
    }
]
```
