For bulk powder premixes, our standard MOQ starts as low as 50 kg to 100 kg for custom R&D formulations, allowing brand owners to complete pilot market validation without excessive capital commitment. For turnkey finished products utilizing custom formula premixes:
• Hard Capsules: Starting at 100 to 500 bottles (or bulk capsules from 50,000 units).
• Stick Packs & Sachets: 10,000 to 30,000 sachets depending on foil barrier thickness and gravimetric fill weight.
• Direct Compression Tablets: 100,000 tablets per run with custom punch dies and debossing available.
Our facility operates under strict NSF 455-2 GMP and ISO 22000 validated protocols. Cross-contamination is mitigated through dedicated cleanroom suites maintained under negative air pressure cascades with HEPA filtration (0.3 micron at 99.97% efficiency). Equipment contact parts are constructed from sanitary 316L stainless steel, disassembled, and validated via ATP swab testing and allergen-specific ELISA kits between lot changes.
Segregation is eliminated by standardizing particle sizes. When blending dense minerals with light botanical powders, we deploy fluidized-bed granulation or micro-milling to achieve a matched bulk density (typically 0.50–0.75 g/mL), preventing particle settling during transport.
Every outbound custom formula premix is accompanied by an audit-ready, batch-specific Certificate of Analysis (COA) containing:
1. Active Assay Potency: High-Performance Liquid Chromatography (HPLC), Gas Chromatography (GC), or Titration confirming 100%+ label claims.
2. Heavy Metal Quantification: Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for Lead (Pb), Arsenic (As), Cadmium (Cd), and Mercury (Hg) strictly compliant with USP <2232> and California Proposition 65.
3. Microbial Limit Testing: Total Aerobic Microbial Count (TAMC < 1,000 CFU/g), Total Combined Yeasts and Molds Count (TYMC < 100 CFU/g), negative E. coli, Salmonella spp., and Staphylococcus aureus.
4. Physical Specifications: Tapped & bulk density, particle mesh analysis, and Loss on Drying (LOD < 5.0%). Full Allergen Declarations and Non-GMO verification statements are provided standard.
Active vitamins (especially Vitamin C, Vitamin D3, Vitamin K2, and Methylcobalamin) experience natural potency attrition over time due to heat, humidity, and atmospheric oxygen. Shaanxi ESNO Biotech Co., Ltd. conducts accelerated stability studies (40°C ± 2°C / 75% RH ± 5% RH for 6 months, simulating 24 months of ambient shelf life) to chart precise degradation curves.
Rather than applying arbitrary overages that risk regulatory non-compliance in strict markets like the EU or Japan, our formulation scientists calculate validated, minimal overages (typically between 5% and 15%) coupled with microencapsulated protective beadlet technology.
