Finally the specification as privided in the tender may differ slightly from that what is finally realized. This may be cause by change of the supplier, changes in the description or simply translation.

To asure customs acceptance (incentive certificate) and documents that allow payment we grant some flexibility in the invoiced specification.


When being installed as exporter of records, we may establish invoices exactly as required, even when the supplier refuses to follow to the official specification. This will be done only, when we are convinced that the material is technically needed and truly sent to the site.

In case even the prices are fixed in the historic specification, we may invoice the historic prices, even when actual prices differ due to changes in the market, or due to new suppliers. This will work only as long as there is sufficient liquidity
