# Product category

Understand how to specify product categories for line items in your integration.

**Element type: Conditional**

**Endpoints used:** [LineItemModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/LineItemModel/)

If your integration offers [Understand quoting](/avatax-for-cdit/iuc6435579077525/ "Learn how AvaTax calculates or quotes customs duties and import taxes when tariff code information is incomplete or missing.") in the shopping cart for collecting money up front, then it must provide a method for users to input a product category. This is necessary when an HS code isn’t available. You can specify the product category with the `category` option at the line item, and it is the full path to the category where the item is included. These categories are separated by " > ". The system accepts multiple category paths per item. In this case, separate category paths with ";".
