CHAPTER 9

TRANSPORT

Article 70

It is recognized that the establishment of the common market necessitates the application of  such rates and conditions for the carriage of coal and steel as will afford comparable price  conditions to comparably placed consumers.

Any discrimination in rates and conditions of carriage of every kind which is based on the  country of origin or destination of products shall be prohibited in traffic between Member  States. For the purpose of eliminating such discrimination it shall in particular be obligatory  to apply to the carriage of coal and steel to or from another country of the Community the  scales, rates and all other tariff rules of every kind which are applicable to the internal  carriage of the same goods on the same route.

The scales, rates and all other tariff rules of every kind applied to the carriage of coal and steel  within each Member State and between Member States shall be published or brought to the  knowledge of the Commission.

The application of special internal rates and conditions in the interest of one or more coal or  steel producing undertakings shall require the prior agreement of the Commission, which  shall verify that they are in accordance with the principles of this Treaty; it may make its  agreement temporary or conditional.
