The *Customs Modules* introduces or extends the following concepts:
|
|
|
|
.. _model-customs.tariff.code:
|
|
|
|
Tariff Code
|
|
===========
|
|
|
|
The *Tariff Code* stores the `Harmonized System`_ code for a `Country
|
|
<country:model-country.country>` or `Organization
|
|
<country:model-country.organization>` active for a period of the year.
|
|
|
|
.. seealso::
|
|
|
|
The *Tariff Codes* can be found by opening the main menu item:
|
|
|
|
|Products --> Customs --> Tariff Codes|__
|
|
|
|
.. |Products --> Customs --> Tariff Codes| replace:: :menuselection:`Products --> Customs --> Tariff Codes`
|
|
__ https://demo.tryton.org/model/customs.tariff.code
|
|
|
|
.. _model-customs.duty.rate:
|
|
|
|
Duty Rate
|
|
=========
|
|
|
|
The *Duty Rate* stores the import or export rate applied for a `Tariff Code
|
|
<model-customs.tariff.code>` over a period and a `Country
|
|
<country:model-country.country>` or `Organization
|
|
<country:model-country.organization>`.
|
|
The rate can be expressed as a fixed amount or an amount per `Unit of Measure
|
|
<product:model-product.uom>` in a `Currency
|
|
<currency:model-currency.currency>`.
|
|
|
|
.. seealso::
|
|
|
|
The *Duty Rates* can be found by opening the main menu item:
|
|
|
|
|Products --> Customs --> Duty Rates|__
|
|
|
|
.. |Products --> Customs --> Duty Rates| replace:: :menuselection:`Products --> Customs --> Duty Rates`
|
|
__ https://demo.tryton.org/model/customs.duty.rate
|
|
|
|
.. _concept-product:
|
|
|
|
Product
|
|
=======
|
|
|
|
The *Product* concept is extended with a set of methods that allow retrieving
|
|
the product's `Tariff codes <model-customs.tariff.code>` based on criteria.
|
|
|
|
The tariff codes can be set directly on the product or on a special type of
|
|
`Product Category <model-product.category>`.
|
|
Unlike standard product categories, each product can only have a single customs
|
|
category.
|
|
|
|
.. seealso::
|
|
|
|
The `Product <product:concept-product>` concept is introduced by the
|
|
:doc:`Product Module <product:index>`.
|
|
|
|
.. _model-product.category:
|
|
|
|
Product Category
|
|
================
|
|
|
|
The *Customs Module* allows some *Product Categories* to be marked as customs
|
|
categories.
|
|
These product categories can have customs properties such as `Tariff Codes
|
|
<model-customs.tariff.code>` associated with them.
|
|
|
|
When placing categories into a structure all the categories in the structure
|
|
must be either standard categories or customs categories.
|
|
This means a customs category cannot have a standard category as its parent or
|
|
as any of its subcategories.
|
|
|
|
.. seealso::
|
|
|
|
The `Product Category <product:model-product.category>` concept is
|
|
introduced by the :doc:`Product Module <product:index>`.
