Potassium Dichromate (K₂Cr₂O₇) Supplier for Non-EU Markets & Authorized Users

Gentrochema supplies Potassium Dichromate (K₂Cr₂O₇) exclusively under specific regulatory conditions and in accordance with applicable international chemical legislation and hazardous goods transport regulations.

Potassium dichromate is a hexavalent chromium compound (Cr VI) listed under REACH Annex XIV (Authorisation List) and classified as a Substance of Very High Concern (SVHC) within the European Union.

Regulatory Status

Gentrochema BV no longer holds an active EU REACH Authorisation for Potassium Dichromate.

As a result, Gentrochema can only supply this product under the following conditions:

• Supply to customers located outside the European Union / European Economic Area
• Supply under T1 customs status (non-EU customs cleared goods)
• Supply to customers who possess their own valid REACH Authorisation for the intended use within the EU/EEA

Potassium dichromate may therefore only be supplied where all applicable regulatory obligations are fulfilled by the customer or where the material remains outside EU customs free circulation.

The substance is highly soluble in water and valued for its oxidizing, corrosion-inhibiting, and metal treatment properties. The product is supplied as an orange crystalline solid.

Due to its toxicological classification and environmental hazards, potassium dichromate is subject to strict regulatory control under REACH, CLP, ADR, IMDG and IATA legislation.

The substance is classified as:

• Toxic
• Carcinogenic
• Mutagenic
• Reprotoxic
• Environmentally hazardous
• Strong oxidizer

Signal word: Danger.

Industrial Applications

Potassium dichromate has historically been used in specialized industrial applications such as:

• Safety matches industry (oxidizing agent)
• Metal surface treatment
• Aerospace & defense applications
• Corrosion inhibition systems
• Laboratory reagents
• Pigment and specialty chemical manufacturing
• Wood preservation systems
• Chromium compound production
• Oxidation processes in chemical industry

In the safety matches industry, potassium dichromate is used as a powerful oxidizing agent in specialized match compositions and ignition systems.

Certain industrial applications within the EU/EEA may still be permitted only where covered by a valid REACH Authorisation held by the user or upstream supply chain.
