Participating companies

Natural stone companies from the Netherlands and Flanders participate in the TruStone Initiative. In doing so, they are working on their responsible business conduct, receive support from the secretariat and meet the requirements of society, governments and other customers (consumers, stonemasons, retailers and contractors). This page lists per participating company since when it is a participating company to the TruStone Initiative and what the progress is with regard to the requirements.

Importing companies participating in the TruStone Initiative report annually to the secretariat. Companies that do not themselves import do not have to submit an annual report.

The assessment framework contains the Initiative’s requirements for due diligence which must be met by importing companies. These requirements become higher the longer a company is a member of the Initiative. The extent to which companies must implement them can differ. This depends, among other things, on the size of the company and its position in the value chain.

Progress of affiliated Dutch and Flemish importers and processors

For importers, the overview below indicates when the company has become a member of the TruStone Initiative and whether it meets the requirements related to the number of years it has been participating. A green number after the company name means that the company meets the requirements associated with the relevant number of years the company has been participating. An orange number means the company is still implementing the requirements. A number that has been crossed out means that the company was not yet a member in the reporting year in question.

A link to the company's action plan is also included. In an action plan, the company indicates which risks it has encountered in its supply chains which it will tackle in the coming year. Companies that do not import materials which originate in, or are processed in, high-risk countries do not have to submit an action plan. High-risk countries are all countries outside of the European Economic Area (all EU-countries, and Iceland, Liechtenstein and Norway).

State of affairs after second year in agreement

Overall companies appear to be on the right track with implementing the international guidelines on responsible business conduct.

However, the insight into circumstances in supply chains in the past year grew only limited. One important reason is that companies were not able to travel in 2020 and partly in 2021 due to the COVID-19 pandemic. Parties within the Initiative point out that it is possible to gather insight through informing local organisations, representatives of workers and other stakeholders in the supply chains (this can be done with the help of civil society organizations that are members of the TruStone Initiative).

To prevent any further delay in tackling encountered risks, parties decided to setup collective projects for which companies are actively invited.
