1. What's the difference between food-grade and industrial-grade products?

A: Food-grade products are FDA/GB certified, with higher purity (e.g., magnesium sulfate ≥99.5%) and strict heavy metal limits. Industrial-grade products meet primary content standards (e.g., ≥98%) but do not require biosafety testing, offering better cost-efficiency for non-human-contact applications.

2. Can food-grade magnesium sulfate be used for homebrewing beer?

A: Absolutely! Food-grade magnesium sulfate serves as a yeast nutrient in brewing. The recommended dosage is 0.01-0.03% to enhance fermentation stability. Mention "brewing use" when ordering to receive a free digital manual.

3. Can industrial-grade tricalcium phosphate be used for 3D printing materials?

A: Industrial-grade tricalcium phosphate (particle size ≤50μm) is suitable for ceramic 3D printing when used with a binder. Bulk orders (10+ tons) enjoy a 10% discount, with customized particle size options available.

4. Why is food-grade potassium citrate more expensive than industrial-grade?

A: Food-grade requires multiple crystallization purifications (higher cost) and 15+ tests (e.g., microbes, arsenic salts). Industrial-grade only tests main content and pH, making it ideal for electroplating or detergents.

5. Do food-grade products come with test reports?

A: Yes! All food-grade products include third-party CNAS-certified test reports (viewable online). Random re-inspection upon delivery is supported, with unconditional returns for quality issues.

6. Can industrial-grade magnesium sulfate be used for agricultural fertilization?

A: Agricultural-grade is recommended (better cost-efficiency). Industrial-grade must be dissolved before spraying (5-8kg/acre). Orders over 1 ton include free soil testing guidance.
