Potassium clavulanate

Buyers must prioritize pharmaceutical-grade purity, typically requiring an assay of 96.0% to 102.0% on a dry basis. It is essential to verify the Clavulanic Acid content and ensure the moisture content (water) is strictly controlled, usually below 0.5%, as this material is highly hygroscopic and degrades rapidly in the presence of humidity. Always request a Certificate of Analysis (CoA) that aligns with USP, BP, or EP standards.

Suppliers must hold a valid GMP (Good Manufacturing Practice) certification. For entry into regulated markets, a DMF (Drug Master File) number is crucial. Additionally, ensure the manufacturer has ISO 9001 for quality management and, if applicable, CEP (Certificate of Suitability) for the European market to streamline the registration process for finished dosage forms.

Potassium Clavulanate is often sold as a 1:1 mixture with Microcrystalline Cellulose (MCC) or Silicon Dioxide because the pure salt is extremely unstable. Buyers should specify whether they need Pure Potassium Clavulanate or a Diluted Mixture. The mixture form is generally easier to handle, store, and process in tablet or suspension manufacturing, reducing the risk of degradation during production.

This product is highly sensitive to heat and moisture. It must be stored in airtight, light-resistant containers, typically at temperatures between 2°C and 8°C (Cold Chain). For long-distance cross-border shipping, ensure the supplier uses vacuum-sealed aluminum foil bags inside fiber drums and provides temperature-controlled logistics to prevent loss of potency.

Utilize Trade Assurance services provided by platforms like Made-in-China.com to ensure payment security. Never release full payment until third-party pre-shipment inspection (such as SGS or Intertek) confirms the chemical identity and purity. For new suppliers, start with a small sample batch for lab testing before committing to container-level volumes.

Since it is a chemical substance, you must ensure the supplier provides a complete MSDS (Material Safety Data Sheet) and a non-hazardous chemical declaration (if applicable) or proper Dangerous Goods (DG) packaging. Verify the HS Code (typically 2941.90) to determine specific import duties and whether an import license for precursor-like chemicals is required in your destination country.

Prices for Potassium Clavulanate are volatile due to the cost of fermentation raw materials. Negotiate based on volume tiers, aiming for a 10-15% discount on orders exceeding 500kg. Ensure the contract specifies a guaranteed shelf life (typically at least 24 months from the date of manufacture) to avoid receiving 'near-expiry' stock that could jeopardize your production timeline.
