Mulberry juice

When evaluating quality, prioritize the Brix level (sugar content), which typically ranges from 8% to 12% for NFC (Not From Concentrate) juice and up to 65% for concentrates. Ensure the product maintains a deep purple-black color without artificial dyes, indicating high anthocyanin content. Additionally, verify the pH level (usually 3.5–4.5) to ensure natural acidity and shelf stability.

Look for suppliers utilizing Cold-Pressing technology combined with HPP (High-Pressure Processing) or UHT (Ultra-High Temperature) flash sterilization. These methods preserve the heat-sensitive antioxidants and Vitamin C better than traditional long-boil pasteurization. For long-distance shipping, aseptic cold-filling is the industry standard for maintaining flavor integrity.

Suppliers must provide HACCP and ISO 22000 certifications to guarantee food safety management. For specific markets, ensure the product meets FDA (USA) or EFSA (EU) regulations, including pesticide residue testing reports and heavy metal limits (Lead/Arsenic). If targeting health-conscious segments, request Organic (USDA/EU), Halal, or Kosher certifications.

Request a Certificate of Analysis (COA) for every batch. The COA should confirm 100% purity with no added sugars, water, or synthetic flavors. You can also ask for Carbon Isotope Ratio Analysis to detect adulteration with C4 sugars (like corn syrup). Made-in-China.com offers verified suppliers who can provide these laboratory validations.

The main risks include fermentation due to temperature fluctuations and packaging leakage. To mitigate this, use Reefer Containers (Refrigerated) for NFC juice or Aseptic Bag-in-Box (BIB) packaging for concentrates. Ensure the supplier uses heavy-duty pallets and shrink-wrapping to prevent movement during sea transit.

Pricing is highly dependent on seasonal harvest cycles (typically April-June). Negotiate Annual Supply Agreements during the harvest peak to lock in lower rates. For MOQs, while large factories prefer 20ft containers, many premium suppliers on Made-in-China.com accept smaller trial orders of 1-2 tons if using standardized packaging.

Utilize Escrow services or Letter of Credit (L/C) to ensure payment is only released upon the presentation of Bill of Lading and Phytosanitary Certificates. Always conduct a pre-shipment inspection (PSI) via third parties like SGS or Intertek to verify that the batch matches the approved sample.

For long-haul shipping, ensure the Cold Chain Logistics are unbroken. Documentation is critical: you must have a Commercial Invoice, Packing List, Certificate of Origin, and Health Certificate. Check your local Customs Tariff codes (HS Code 2009.89) to calculate import duties and VAT accurately before finalizing the purchase.
