Norfloxacin powder

Norfloxacin is a fluoroquinolone antibiotic primarily used in veterinary and human medicine. When sourcing, you must ensure the product complies with international pharmacopoeia standards such as USP (United States Pharmacopeia), BP (British Pharmacopoeia), or EP (European Pharmacopoeia). The assay content should typically be 99.0% to 101.0% on a dried basis. Key parameters to verify include heavy metal limits (≤20ppm), loss on drying (≤1.0%), and residue on ignition (≤0.1%). Always request a Certificate of Analysis (COA) for every batch to confirm these specifications.

As an Active Pharmaceutical Ingredient (API), Norfloxacin requires strict documentation. Buyers should prioritize suppliers with GMP (Good Manufacturing Practice) certification to ensure quality management. For entry into specific markets, a CEP (Certificate of Suitability) or a DMF (Drug Master File) is often necessary. Additionally, ensure the manufacturer is registered with the relevant local authorities, such as the FDA for the US or EDQM for Europe, and check for ISO 9001 or ISO 14001 to verify operational and environmental standards.

Norfloxacin is practically insoluble in water and slightly soluble in ethanol. For liquid formulations, you may need to source Norfloxacin Nicotinate or Norfloxacin Lactate, which offer better water solubility. The powder is light-sensitive and should be stored in tight, light-resistant containers. Ensure the supplier uses double-layer PE bags inside fiber drums to prevent degradation during transit and storage.

In the B2B sector, Norfloxacin powder is mainly purchased by pharmaceutical manufacturers to produce tablets, capsules, or ophthalmic solutions. In the veterinary sector, it is widely used for treating gastrointestinal and urinary tract infections in poultry and livestock. Buyers must ensure the particle size (mesh size) is compatible with their specific manufacturing equipment, such as high-speed tableting machines or powder blending lines.

The biggest risks involve customs seizure due to lack of proper documentation and purity discrepancies. Because Norfloxacin is a regulated substance, missing a Health Certificate or Export License can lead to total loss. To mitigate this, use third-party inspection services (like SGS or Intertek) to conduct pre-shipment testing and quantity verification. Always verify the supplier's reputation on Made-in-China.com by checking their Audit Reports and 'Diamond Member' status.

Negotiation should focus on volume-based pricing and payment security. For orders exceeding 500kg, you can typically negotiate a 10-15% discount. Instead of full advance payment, propose a 30% deposit and 70% against the Bill of Lading (B/L) or use Letter of Credit (L/C) for large-scale transactions. Additionally, negotiate for free replacement if the third-party lab results do not match the provided COA.

Norfloxacin is generally classified as non-hazardous for transport, but it still requires a Material Safety Data Sheet (MSDS) and a Non-Hazardous Cargo Appraisal Report for air or sea freight. Ensure the packaging is vacuum-sealed to prevent moisture absorption. For shipping to regions with high humidity, specify the use of desiccants within the outer drums. For reliable sourcing and logistics support, buyers should consult verified gold-tier manufacturers on Made-in-China.com who have experience with international shipping regulations.

Always conduct transactions through secure payment channels and avoid direct transfers to private bank accounts. Utilize the trading security services provided by professional B2B platforms like Made-in-China.com to ensure that funds are only released upon proof of shipment. Before placing a bulk order, always request a paid sample (typically 100g-500g) to verify the quality in your own laboratory.
