In recent months, the global raw materials market—especially tungsten—has seen significant fluctuations and increasing volatility. Tungsten is a key element in the production of carbide and has a significant impact on the cost of our tools. To ensure continuity of supply while adopting criteria that are as fair and transparent as possible, we have introduced a price adjustment system based on the APT index (Ammonium Paratungstate), an international benchmark for the cost of tungsten.
How it works
- Each item is associated with a fixed APT coefficient, which represents the impact of the raw material on the finished product.
- This coefficient does not change over time.
- The price variation is determined solely by the trend in the raw material cost (ΔAPT).
Calculation of the surcharge
The surcharge is therefore calculated by combining:
- APT coefficient (fixed)
- APT variation (updated periodically)
Price updates
The APT value is monitored on a monthly basis. The price list is updated regularly to reflect changes in the raw material cost, both increases and decreases. This means that:
- If the cost of tungsten increases
A surcharge will be applied - If it decreases
The surcharge will also decrease
Transparency and objectivity
This system makes it possible to:
- Apply an objective criterion, linked to a recognized market index
- Ensure transparency in price formation
- Pass through raw material changes in a clear and verifiable way
The APT reference value is publicly available and can be consulted through independent sources.
