Dried blueberries

Quality evaluation should focus on moisture content (typically 12-18%), sugar-to-acid ratio, and uniformity of size. Buyers should distinguish between Wild (Lowbush) blueberries, which are smaller and more flavorful, and Cultivated (Highbush) blueberries, which are larger and meatier. Ensure the product is free from stems, leaves, and foreign materials, and check for color consistency (deep purple to black) as an indicator of proper drying techniques.

Identify whether the product is Infused (with sugar or apple juice) or Natural (no sugar added). Freeze-drying (FD) preserves the most nutrients and shape but is more expensive, while Air-drying (AD) or Osmotic Dehydration is more common for snacks and baking. Verify if sunflower oil is used as an anti-caking agent (usually <1%) to prevent clumping, and confirm if the product is Sulphur-free to meet clean-label requirements.

Suppliers must provide HACCP and ISO 22000 certifications for food safety management. For specific markets, FDA registration (USA), EFSA compliance (EU), or GFSI-recognized certificates (like BRC or IFS) are essential. Additionally, Phytosanitary Certificates are required for customs clearance, and Organic (USDA/EU Organic) or Kosher/Halal certifications may be necessary depending on your target consumer base.

Bulk orders should be packed in multi-layer moisture-proof bags (e.g., PE or aluminum foil) inside double-corrugated export cartons. For retail-ready goods, nitrogen-flushed vacuum packaging is recommended to prevent oxidation and extend shelf life to 12-18 months. Ensure labels include batch numbers, production/expiry dates, and storage instructions (cool, dry place below 20°C).

The primary risks include microbiological contamination (e.g., Salmonella, Yeast, and Mold) and pesticide residue levels exceeding local limits. To mitigate this, always request a COA (Certificate of Analysis) for every batch and utilize third-party inspection services (like SGS or Intertek) to conduct pre-shipment sampling and testing.

Focus on volume-based pricing tiers; ordering in full container loads (FCL) can significantly reduce freight and unit costs. Negotiate payment terms such as 30% deposit and 70% against the Bill of Lading (B/L) to protect your cash flow. For long-term partnerships, ask for fixed-price contracts to hedge against seasonal price fluctuations in the raw fruit market.

Dried blueberries are sensitive to heat; for long-haul sea freight through tropical zones, consider reefer containers (refrigerated) set at 5-10°C to prevent sugar blooming or clumping. Ensure the Incoterms are clearly defined (e.g., FOB or CIF) and that the supplier provides all necessary Customs HS Code (typically 0813.40) documentation to avoid clearance delays.
