Chromic acid flakes 99.9% manufacturers

For high-purity industrial applications, you must ensure the CrO3 content is ≥99.9%. Pay close attention to the impurity limits, specifically sulfate (SO4) content <0.05% and insoluble matter <0.01%, as these directly affect the quality of electroplating baths. The physical form should be dark red flakes without significant clumping, which indicates moisture absorption.

Chromic Acid Flakes at 99.9% purity are primarily used in functional chrome plating (hard chrome) for automotive and aerospace parts, decorative plating for consumer goods, and as a strong oxidizing agent in organic synthesis. It is also critical in wood preservation and the manufacturing of high-purity catalysts.

Suppliers must provide a Material Safety Data Sheet (MSDS/SDS) compliant with GHS standards. For international trade, ensure the product meets ISO 9001 for quality management. Because it is a hazardous material, the manufacturer should hold a Production License for Dangerous Chemicals and comply with REACH regulations if exporting to the EU.

Chromic acid is highly corrosive and an oxidizer. It must be packed in hermetically sealed steel drums (typically 25kg or 50kg) with internal plastic liners. Ensure the drums are UN-certified for hazardous goods. Storage must be in a cool, dry, and well-ventilated area, strictly separated from organic materials, reducers, and flammable substances.

Chromic Acid is classified as a Class 5.1 Oxidizer (UN 1463) with secondary Class 8 Corrosive risks. You must use a freight forwarder specialized in Dangerous Goods (DG). Failure to declare correctly can lead to heavy fines, cargo seizure, or port rejection. Always verify the IMDG Code compliance for sea freight to ensure safe transit to your specific country.

Use Made-in-China.com's audited supplier reports to verify the factory's physical existence and export licenses. For payment, utilize secured payment terms or Letters of Credit (L/C) that release funds only upon the presentation of a valid Certificate of Analysis (COA) and a Pre-shipment Inspection Report from a third party like SGS or Intertek.

Prices for Chromic Acid are highly sensitive to raw material (Chrome Ore) market fluctuations. Negotiate based on volume-based pricing tiers; for example, ordering in full container loads (FCL) can reduce unit costs by 10-15%. Request a price validity period (e.g., 7-14 days) to protect against sudden market spikes during the procurement process.

Check your local import tariffs and anti-dumping duties on Chinese chemicals. Ensure the supplier provides a Commercial Invoice, Packing List, and Bill of Lading that matches the HS Code (typically 281910) exactly. Some countries require an Import Permit for Precursor Chemicals or specific environmental clearances before the goods arrive at the port.
