8. Professional FAQ (Technical & Manufacturing Terminology)

Q1: What does "avermectin B1/B2 ratio" refer to and why is it significant?
The B1/B2 ratio reflects the proportion of B1a+B1b isomers versus B2a+B2b in the technical mixture. A higher B1 ratio (>90%) often indicates enhanced bioefficacy for veterinary and agricultural applications.
Q2: How does ISO9001 certification benefit avermectin factory clients?
ISO9001 certification ensures all processes (from raw fermentation to packing) are quality managed and traceable, reducing impurity risks and ensuring consistent product batch-to-batch.
Q3: What is “CNC processing” in avermectin manufacturing?
Critical contact parts (rotary evaporators, fermenters) are precision-machined using CNC to achieve low-surface roughness (Ra<0.8μm), boosting hygiene and reducing contamination.
Q4: What is a "pharmaceutical grade COA"?
Certificate of Analysis (COA) issued for pharmaceutical-grade avermectin follows ISO/USP/FDA format, listing all relevant impurities, solvent residues, and micro/metal analyses.
Q5: Can avermectin be customized for different industries?
Yes, manufacturers offer custom avermectin for animal health (high-purity B1, ISO standards), agriculture (cost-effective B mixture), and pharma (ultra-low residue, FDA/DMF registration).
Q6: What is the typical shelf-life and what factors affect it?
Shelf-life is 24–36 months, affected by packaging (oxygen barrier drums), storage (cool, dry, ≤25°C), and B1 isomer stability, as proven in HPLC accelerated aging tests.
Q7: Which standards apply to avermectin exports?
Exports must comply with ISO, US FDA (CFR Title 21), EU EMA, and destination country residue/MRL laws. COA, SDS, and test reports must be provided for import customs.
