A published chemistry serves to inform traders, consumers and producers in distant corners of the globe what standard they may expect when entering a contract. The MMTA provides these standards across a wide range of minor metals as a benchmark.
The publication of norms for chemical specification are provided by the MMTA in order to give general trade guidance. In this way the MMTA attempts to set acceptable standards, thus assisting the smooth running of the minor metals trade.
As ever in any minor metals contract, any specific agreement between two trading parties may overrule an MMTA standard if agreed by both principals in advance. If you have suggestions for the inclusion of a new norm or the renewal & updating of an existing one, please do not hesitate to submit your comments by contacting the Executive.
Significant as the chemical norms are in providing a standard contractual specification between traders, so the Sampling and Assaying Standards provide detailed guidelines as to how minor metals in their various forms should be weighed, sampled and assayed, so that results are universally accepted.
