âť“ Purchasing Guide & FAQ

What purity grade should I choose for Kojic Acid?

For cosmetic use, always select "Cosmetic Grade" or higher (99%+ purity for most actives). Technical grade may contain impurities unsuitable for skin contact. Check the supplier's COA (Certificate of Analysis) for heavy metals, microbial limits, and purity confirmation.

What is a typical MOQ and how do I negotiate?

Minimum Order Quantities range from 1kg to 25kg depending on the supplier and ingredient. For startups, look for suppliers offering 1-5kg MOQs. You can often negotiate lower MOQs by agreeing to higher per-kg pricing, or by combining multiple ingredients in a single order.

How do I verify a supplier's credibility?

Prioritize "Verified Supplier" and "Trade Assurance" badges on Alibaba. Check the supplier's years in business (3+ years preferred), transaction volume, and response rate. Request samples before committing to bulk orders, and always use Alibaba's secure payment system.

How should Kojic Acid be stored and handled?

Store in a cool, dry place away from direct sunlight. Use airtight containers to prevent moisture absorption. Follow the supplier's MSDS (Material Safety Data Sheet) for specific handling precautions. Some actives (like Vitamin C) are sensitive to air and light—consider opaque or amber packaging.

Can I request custom packaging or private labeling?

Many Alibaba suppliers offer OEM/ODM services including custom packaging, private labeling, and even formulation assistance. Minimums for custom packaging typically start at 500-1000 units. Contact suppliers directly through the links above to discuss your specific requirements.
