Four Essential Documents in International Raw Material Trade: COA, MSDS, TDS, MOA

n raw material trading, formulation development, and international logistics, four types of documents are encountered daily. Whether you are a formulator, procurement specialist, salesperson, or brand owner, understanding their purposes will help you avoid costly mistakes.

1. COA – Certificate of Analysis

• Full Name: Certificate of Analysis
• Purpose: Issued by the manufacturer’s quality control department to provide specific test results for a batch (purity, content, impurities, moisture, molecular weight, microbiology, etc.)
• Applications:
  • For buyers to confirm product compliance before ordering or after receipt
  • Customs inspection (especially for food, pharmaceutical, and cosmetic raw materials)
  • Factory record-keeping
• Key Information: Batch number, production date, test parameters, specification limits, actual results, test methods, conclusion

2. MSDS – Material Safety Data Sheet (now commonly SDS)

• Full Name: Material Safety Data Sheet (older term); current standard: SDS – Safety Data Sheet
• Purpose: Describes the product’s hazards, safe handling, storage conditions, spill procedures, and first-aid measures
• Applications:
  • Required for most international shipments (air and sea freight)
  • Safety assessment before customer use in plants or labs
  • Customs declarations and dangerous goods reporting
• Key Information: Composition, hazard classification, protective measures, firefighting, spill handling, transport information

3. TDS – Technical Data Sheet

• Full Name: Technical Data Sheet
• Purpose: Provides technical performance data, recommended use methods, physical and chemical properties, suggested dosage, compatibility, etc.
• Applications:
  • Customer formulation development and product testing
  • Product promotion and technical communication
  • Sales teams providing technical explanations to customers
• Key Information: Appearance, active ingredient content, recommended dosage, solubility, pH, stability, usage recommendations

4. MOA – Mechanism of Action

• Full Name: Mechanism of Action
• Purpose: Explains how an ingredient or drug works at the molecular or cellular level within a living organism
• Applications:
  • Scientific basis for functional ingredients (e.g., whitening, anti-aging, testosterone support, weight loss)
  • Building trust with formulators and R&D customers
  • Product marketing materials and white papers
• Key Information: Target, pathway, in vitro/in vivo study results, causal relationship with efficacy
