CE marking in roofing slates

PlantillamarcadoCECE marking is mandatory for all the products sold in the European Union, regardless of the country of origin of the products. In the case of roofing slate, this marking is done using the data obtained from the tests of EN 12326 (parts 1 and 2) Slate and natural stone for discontinuous roofing and cladding. The CE mark does not establish qualities, just gives information about product features. The different qualities of the slate are established by the manufacturer taking into account the market requirements and its own standards.

The results of the tests of EN have to be stated on a label attached to each pallet or slate cage. In paragraph ZA of EN 12326-1 is an example of CE label, although there are other solutions.

Together with this label must be included another document, the declaration of conformity, in which it is specified in detail the characteristics of the slate. This document must accompany each sold batch of slate; there is no need to include it to slate pallet or cage. As for the label, there is a model in Part 1 of the standard.

The CE marking is mandatory for roofing slate since 2004, so it is sufficiently well established between producers and consumers. However, there are still companies that refuse to incorporate it to their products, either by ignorance or negligence law, thereby risking a sanction by the competent authority.

World´s roofing slate market in 2011

Producing countries versus consuming countries

A brief analysis of the global market for roofing slate in 2011 reveals a number of interesting conclusions. Spain still remains the largest exporter of slates in the world, followed by China and Brazil. Spanish exports in dollars (graphic 1) are well above those of China and Brazil, but not so for exports measured in tons (graphic 2), where China is close to the production volume of Spain. Regarding to consuming countries, in 2011 France was the largest consumer, followed by the UK, Germany and the United States.

Evolution 2011

Taking into account the selling prices for slate, measured in $/ton (graphic 3), Spain, the largest producer, sells its slate at an average price of $ 657/ton, down from the average of 855 $/ton. However, this price is higher than the sales of China (343 $/ton) and Brazil ($ 479/ton). In fact, the overall average price rises due to high sale prices of Central European countries (Germany, France, Belgium and Italy) that had a very limited production but sold at high prices their production into their own markets for restoration of historical monuments and singular buildings. On the other hand, the buying price (graphic 4) for all the countries is closer to the average (787 $/ton), except for the case of China (1,412 $/ton) and Brazil (1,071 $/ton). These two countries buy little roofing slate (graphics 1 and 2) but at very high prices. Thus, it is possible to draw a conclusion: China, and to a lesser extent Brazil, are potential consumers of roofing slate. The opening of these markets to European production companies can be a good solution for the economic crisis that many of these companies are experiencing.
