China climbazole

When sourcing Climbazole, the purity (Assay) should be ≥99.0% to ensure efficacy as an anti-fungal agent. Key physical properties include a melting point between 96°C and 100°C and a loss on drying of ≤0.5%. It should appear as a white to off-white crystalline powder. Buyers must request a Certificate of Analysis (COA) for every batch to verify these parameters, as impurities can affect the stability of the final cosmetic formulation.

Climbazole is strictly regulated. In the European Union (Annex III of the Cosmetics Regulation), it is permitted as a preservative at a maximum concentration of 0.5% in leave-on products and up to 2.0% in rinse-off hair products (like anti-dandruff shampoos). For the US market, ensure the supplier provides a Material Safety Data Sheet (MSDS/SDS) and complies with CIR (Cosmetic Ingredient Review) guidelines. Always verify that the manufacturer follows Good Manufacturing Practices (GMP).

Climbazole is a topical antifungal agent primarily used in anti-dandruff shampoos, scalp treatments, and medicated soaps. It works by inhibiting the synthesis of ergosterol in fungal cell membranes. It is highly effective against Malassezia furfur. In formulation, it is lipophilic, meaning it requires proper solubilization (often using surfactants or alcohols) to remain stable and prevent precipitation in aqueous solutions.

Pricing is heavily influenced by raw material costs (specifically 2-chlorophenol) and environmental regulation compliance in China. Bulk buyers can achieve 15-20% cost savings by moving from 25kg drums to 1-ton metric orders. It is recommended to source from suppliers on Made-in-China.com who offer tiered pricing and have integrated supply chains to mitigate price volatility.

Climbazole is generally classified as environmentally hazardous (UN3077, Class 9) for bulk transport. It must be shipped in UN-approved packaging (typically fiber drums with PE inner bags). Ensure the cargo is kept in a cool, dry, and well-ventilated area, away from strong oxidizing agents. For sea freight, use moisture-proof containers to prevent clumping during long-duration transit.

Utilize Trade Assurance services provided by platforms like Made-in-China.com to protect payments until delivery is confirmed. Before placing a large order, always request a 100g-500g sample for lab testing. Conduct a factory audit or hire a third-party inspector (like SGS or Intertek) to verify the supplier's ISO 9001 and ISO 14001 certifications to ensure consistent quality and environmental compliance.

Focus on long-term contract pricing rather than spot-market buys to stabilize costs. Negotiate payment terms such as 30% deposit and 70% against the Bill of Lading (B/L) for established relationships. Inquire about custom particle size (micronization) requirements, as specialized processing can be a point of negotiation for value-added service without significant price hikes.

Check the HS Code (typically 380899 or 293329) for specific import duties in your country. Be aware of anti-dumping duties that may apply in certain regions. Ensure all documentation, including the Commercial Invoice, Packing List, and Certificate of Origin, accurately reflects the chemical name and concentration to avoid customs clearance delays or seizures.
