Lysine hcl 98.5% price manufacturers

Buyers must ensure the product meets the 98.5% purity threshold (calculated on a dry basis). Key parameters include Loss on Drying (≤1.0%), Specific Rotation (+18.0° to +21.5°), and Ammonium Salt content (≤0.04%). For feed-grade applications, the L-Lysine content should be at least 78.8%.

Suppliers should ideally hold FAMI-QS (Feed Additive and Pre-Mixture Quality System) or ISO 22000 certifications. For export to the EU, EFSA compliance is necessary, while US-bound goods must align with FDA and AAFCO (Association of American Feed Control Officials) guidelines to ensure the product is free from harmful contaminants like heavy metals (Lead ≤5ppm, Arsenic ≤2ppm).

Lysine is typically produced via microbial fermentation using corn starch or liquid glucose. High-quality suppliers use advanced membrane filtration and crystallization technologies to ensure high purity and low dust levels. Granular forms are often preferred over fine powders to reduce caking and improve flowability in automated feed mixing systems.

The product is hygroscopic and should be stored in a cool, dry, and well-ventilated warehouse away from direct sunlight. The standard shelf life is 24 months when kept in original, unopened packaging (usually 25kg bags or 650kg-1000kg jumbo bags). Ensure the inner PE liner is intact to prevent moisture absorption.

The primary risks include price volatility due to fluctuations in corn (raw material) prices and quality degradation during long-term sea transit. To mitigate this, use third-party inspections (like SGS or BV) at the loading port to verify the Certificate of Analysis (COA) against the actual batch.

Focus on volume-based pricing tiers; ordering in Full Container Loads (FCL), such as a 20GP container (approx. 18-20 tons), significantly reduces the unit cost compared to LCL. Discuss long-term supply contracts to hedge against market price spikes, and request Free Time at Destination (14-21 days) to avoid demurrage charges.

Always utilize Secured Trading Services provided by platforms like Made-in-China.com to ensure payment is only released upon proof of shipment. For large orders, use Irrevocable Letters of Credit (L/C at sight) or Telegraphic Transfer (T/T) with a 30% deposit and 70% against the Bill of Lading (B/L) copy.

Ensure the supplier provides a Material Safety Data Sheet (MSDS), even though it is generally classified as non-hazardous. For shipping to regions like Southeast Asia or South America, verify the HS Code (2922419000) to confirm import tariffs and check if a Certificate of Origin (Form E or Form RCEP) is required to claim preferential duty rates.
