About the World Customs Organization
What is the WCO?
The Customs Co-operation Council (CCC), now known as the World Customs Organization (WCO), was established in 1952. Today, the WCO represents 183 Customs administrations across six regions worldwide that collectively process approximately 98% of world trade. As the global centre of Customs expertise, the WCO is the only international organization with competence in Customs matters and can rightly call itself the voice of the international Customs community.
The World Customs Organization develops international standards, fosters cooperation and builds capacity to facilitate legitimate trade, to secure a fair revenue collection and to protect society, providing leadership, guidance and support to Customs administrations.
What is the WCO Publications and Data Solutions Service?
The Publications and Data Solutions Service of the World Customs Organization provides standards, primarily in English and French, on categorizing goods and rules governing the trade in these goods worldwide. Linked directly with the WCO’s decision-making bodies, only the Publications and Data Solutions Service is authorized to produce and circulate these official rules.
In order to meet all kinds of needs, our content is available in different formats and media, both offline (books, binders, CD-ROMs) and online (databases, structured content, application programming interface). You can find these items on our e-commerce site at wcoomdpublications.org or in our online database at wcotradetools.org.
The new wcoomdpublications.org interface, also called the Bookshop.
About WCO Trade Tools
What is wcotradetools.org?
Wcotradetools.org is a platform set up by the WCO that hosts the three main international Customs standards: the Harmonized System, Origin and Valuation. Alongside these Customs standards, the platform provides legal texts, such as the Revised Kyoto Convention, accompanied by its Annexes and Guidelines – explanatory texts clarifying the provisions and setting out some of the measures that can be followed in implementing the Convention.
In addition to the latest updated versions and their history, the site offers many different functionalities and services, such as the HS correlation tables, a cross-referenced search for HS codes in trade agreements and the option to add notes and comments for yourself or a user group.
In which languages are the services and products available?
The platform as a whole and some content are available in the WCO’s two official languages, English and French. Most of the content is also available in Spanish, and there is some content in Russian and Italian. (Some editions of the Harmonized System prior to 2017 are available in all five languages.)
If you want to change the language, you will find a dropdown list in the menu (top right-hand side of the page).
To change the language more specifically in the Harmonized System, you can change the selection directly on the introductory page for the nomenclature.
What information on tariff and trade affairs will I find?
The WCO’s Publications and Data Solutions Service produces and circulates the Customs Rules of Origin, Customs Valuation Rules and the Harmonized Commodity Description and Coding System or Harmonized System (HS):
The Harmonized System is a means of designating products with the same code worldwide. It consists of a Nomenclature, Explanatory Notes and Classification Opinions.
The Origin platform includes more than 260 international agreements with their preferential rules, including their rules of origin and the ability to browse their PSRs (Product Specific Rules).
The Valuation Rules ensure that the WTO Customs Valuation Agreement is interpreted and applied in a uniform manner.
About Customs rules and standards
Who are the WCO Customs rules meant for?
The World Customs Organization’s Customs standards and procedures apply across a huge value chain and a wide range of stakeholders in international trade:
goods manufacturers and industrial producers, to help them to define their import needs and assess their export trade capacities;
wholesalers, importers and exporters;
Customs brokers, experts in Customs formalities;
specialist legal advisers;
international carriers and logisticians;
intergovernmental and international organizations, on the basis of trade agreements and arrangements;
States and their administrations responsible for supervising trade in goods, compliance with the rules, Customs formalities and recovery of Customs duties;
training bodies in this sector.
What are the customs "standards"?
Customs “Standards” (HS, Origin and Valuation) are essential components of the trading system and are used by Customs around the world. The WCO, as the only international organization bringing together national Customs administrations, plays a major role in setting these customs standards and in ensuring common interpretation thereof.
What is the HS, the Harmonized System?
The Harmonized Commodity Description and Coding System, generally referred to as the "Harmonized System" or simply the "HS", is a multipurpose international product nomenclature developed by the WCO, in the early 1970’s, to classify traded products. Since then, the HS has become the universal economic language essential to the fluidity of international trade. Used by more than 200 countries the system enables the classification of over 98% of merchandise in international trade.
The HS is made up of information at multiple levels. It comprises 21 Sections, which are subdivided into 97 Chapters. These are further split into approximately 1,300 headings and over 5,000 subheadings, classifying more than 5000 group of commodities. Each subheading is identified by a six-digit code, arranged in a legal and logical structure, and is supported by well-defined rules to achieve uniform classification. This structure, called the Nomenclature, is freely accessible on the WCO’s platform. Every five years, a new version of the Nomenclature is published, featuring new commodities. The last edition was issued in 2017 and the next one is planned for 2022.
What is Origin ?
The WCO defines rules of origin as "the specific provisions applied by a country to determine the origin of goods and using principles established by national legislation or international agreements." (Revised Kyoto Convention). In parallel with customs classification and assessment, country of origin determination is an essential element in determining the amounts of customs duties and taxes.
There is no international definition of origin, although a distinction is made between two systems: preferential and non-preferential. In the case of preferential Origin, everything is based on bilateral or multilateral agreements (free-trade agreements (FTAs), Customs unions, free-trade areas, etc.) or unilateral non-reciprocal preferential arrangements (GSP, etc.). In the case of non-preferential Origin, each country applies its own rules, even if they can be harmonized within some regional economic unions.
What is Valuation ?
Determining the customs value of imported goods is essential to the application and calculation of customs tariffs. All customs administrations of the current WTO Members value imported goods in accordance with the provisions of the WTO Customs Assessment Agreement (including the former GATT Article VII and Tokyo Round Valuation Code), adopted in 1994. The Agreement essentially bases the customs value on the transaction value of imported goods, i.e., the price paid or payable for imported goods, if any, after certain costs and fees adjustments. 90% of trade is valued on the basis of the transaction value method. The Agreement is intended to provide a single, fair, uniform and neutral customs valuation system for imported goods.

¿Dónde puedo encontrar las opiniones de clasificación?
Las opiniones de clasificación se muestran en la nomenclatura al nivel de dígitos al que se refieren. La mayoría de las opiniones de clasificación están disponibles en niveles de subpartidas como 2209.00, 2208.90, 3824.99, 7326.90. Para ver la mayoría de las opiniones de clasificación es necesario alcanzar un nivel de seis dígitos.
Sin embargo, a diferencia de la base de datos anterior, también puede encontrar opiniones de clasificación a nivel de sección y capítulo para las secciones XVI y XVII y para el capítulo 55.
Estos cambios introducidos en la nueva plataforma buscan imitar mejor la versión impresa de la nomenclatura y acercarse técnicamente al contenido original.
Cómo buscar en la nomenclatura del SA
Búsqueda básica
El motor de búsqueda ofrece la posibilidad de realizar una búsqueda en la nomenclatura. Para hacerlo, puede introducir una palabra clave o un código de SA; esta es una función básica que luego mostrará todas las menciones de la palabra o dígito dentro de la nomenclatura.
Por ejemplo, buscar "carne" arroja como resultado 82 menciones de la palabra en cualquier parte de la nomenclatura, ya sea una sección, subpartida o nota explicativa, etc. La parte de donde provienen los resultados se mencionará en la línea de resultados cuando consulte las 82 menciones de carne. Si busca 29.34, se mostrarán ocho resultados, lo que significa que este dígito aparece 8 veces en la nomenclatura. También puede combinar los dos y buscar al mismo tiempo “carne” y “29.34”, solo se mostrará un resultado y se refiere a: peptonas de carne.
Dependiendo de lo que busque, puede combinar palabras clave y dígitos. También puede buscar usando varias palabras al mismo tiempo, como carne y pato.
Búsqueda avanzada: buscar dentro de un contenido específico
Si desea realizar una búsqueda más exhaustiva, puede utilizar la función de búsqueda avanzada. Permite al usuario refinar su resultado centrándose específicamente en determinadas partes y contenidos de la nomenclatura.
Para hacerlo, haga clic en la cruz para abrir el panel de búsqueda avanzada.
1. Este campo permite al usuario seleccionar la parte de la nomenclatura a la que desea dirigir su búsqueda (al seleccionar: sección, capítulo, partida, supbartida
O buscar un tipo particular de contenido dentro del Sistema Armonizado (al seleccionar: notas legales, notas explicativas, opiniones de clasificación
O seleccionar contenido específico en las tablas correspondientes (al seleccionar el número TIN y CAS
@hsnomenclature (esto buscará en todos los títulos (sección, capítulo, partida, subpartida) Y en notas legales PERO NO en opiniones de clasificación, notas explicativas.
2. Puede escribir las palabras clave a buscar en este espacio.
3. El operador booleano permite al usuario agregar una nueva línea de criterios seleccionando: Y, O, No
También puede ajustar el año y el idioma de la edición que esté buscando.
Por ejemplo, para buscar una palabra clave o un dígito en las notas explicativas, escriba: @explanatorynotes carne o @explanatorynotes 2504
Buscar CAS o INN
Cuando busque CAS o INN, utilice la funcionalidad avanzada o escriba @cas o @inn y luego escriba el nombre o número que esté buscando. Por ejemplo: @cas 1372784-20-7; se deben escribir todos los números y guiones
O @inn hialuronato de sodio
En nuestra base de datos se hace referencia a alrededor de 4500 CAS y INN, si no encuentra el que busca significa que ha sido procesado por la OMA. Le recomendamos ponerse en contacto con la aduana de su país para obtener más información.

I have a multi-user account
There are several of us with a subscription and we would like to set up a group. How do we do this?
To put together a working group on the platform, you need to set up an account and take out a single multi-user subscription with the desired number of users. The administrator of the multi-user account can then invite as many members as there are places available under the subscription fee. All you have to do is enter the relevant e‑mail address and confirm the invitation. Those invited will receive an e‑mail inviting them to join the team on the platform.
If invitees do not yet have an account, they simply need to create one by clicking on the registration link in the e‑mail. It will not then be necessary to take out a subscription: access to the content and functionalities will have already been arranged by the team manager.
If invitees currently have an account and a subscription, they will be asked to confirm the transfer from one subscription to another. This means that they will not be able to take advantage of the access provided in their initial subscription pack, which will end on the date specified when new the subscription is taken out.
How do you add a new user to a multi-user account?
To add a new user to your multi-user account, you must be the team manager. If not, you will not be able to add anyone to the team.
If you are the team manager, you must first log into your personal profile and go into the “My team” section. You can then check at the bottom of the list how many places are available for new users in the subscription pack.
If there are none, please change to a different subscription fee and increase the number of users you would like to have in your team. To do this, click on the link in the purple banner. Please note that increasing the number of people in your team will lead to an increase in your subscription fee.
If you have an available place in your subscription pack, click on the “Add team member” button below the list. Enter the e‑mail address of the person you want to add to the team and confirm it. An invitation e‑mail will be sent.
A green line will appear in the “My team” table, showing a summary of the invitation. This gives the date on which the invitation was sent, the addressee’s e‑mail address and a rubbish bin icon so that you can cancel the invitation if you wish.
How do you remove a user from your multi-user account?
To remove someone from your multi-user account, you must be the team manager. If not, you will not be able to remove anyone from the team.
If you are the team manager, go into the “My team” section in your personal profile. Then, in the list, select the person you want to remove, click on the rubbish bin and confirm the removal of the person from your team. If you confirm this, the person will be permanently removed from the team and will no longer have access to the shared documents, tags and files. This will make a new place available in your subscription pack.
How do you change the team manager of a multi-user account?
Only the team manager can change the person responsible for managing a multi-user account. To do this, go into the “My team” section in your personal profile. From your account, alongside your name, click on the “Change the team manager” button. A window should pop up on your screen where you can select the new team manager from your team. Click on the team member, click on the “Select” button and, to complete the process, confirm the new team manager.
