Wholesale dry grape

When sourcing dry grapes, quality is categorized by size uniformity, moisture content, and color consistency. Buyers should prioritize Grade A or AAA products which feature a moisture content between 13% and 18% to ensure shelf stability without being overly dry. Check for sugar bloom (crystallization), which indicates age, and ensure the cap-stem removal rate is above 98% for premium processing standards.

Compliance is critical for food safety. Ensure the supplier adheres to HACCP (Hazard Analysis and Critical Control Points) and ISO 22000 food safety management systems. For specific markets, verify FDA registration (USA), EFSA standards (EU), or Phytosanitary Certificates. It is essential to request lab reports testing for pesticide residues, ochratoxin A, and sulfur dioxide levels, ensuring they fall within the legal limits of the destination country.

The drying method significantly affects the flavor and nutrients. Sun-dried grapes offer a traditional deep flavor, while shade-dried grapes (common for green raisins) preserve more natural color and vitamins. Ask if the supplier uses laser sorting and X-ray machines to remove foreign materials like stones, glass, or metal, and confirm if vegetable oil coating (usually <0.5%) is applied to prevent clumping.

To maintain freshness during sea freight, dry grapes should be packed in polyethylene liners inside corrugated export cartons (usually 10kg or 12.5kg). For high-humidity routes, vacuum packaging or the inclusion of desiccants is recommended. Ensure the outer packaging is clearly labeled with batch numbers, production dates, and storage instructions (cool, dry place at 5-10°C).

Always mandate a Pre-Shipment Inspection (PSI) by a third party like SGS or Intertek. Request a Fumigation Certificate to ensure the container is free from pests. Using Made-in-China.com's Secured Trading Service can also protect your payment until the quality is verified.

Negotiate based on seasonal harvest cycles; prices are often most competitive immediately after the harvest (typically August-October). Request tiered pricing based on volume and ask for a 5% discount on repeat annual contracts. If the supplier cannot lower the price, negotiate for better payment terms (e.g., 30% deposit, 70% against B/L copy).

Dry grapes are sensitive to temperature fluctuations. For long transit times through tropical zones, consider Reefer Containers (refrigerated) set at 10°C to prevent sugar fermentation and darkening. Ensure the Incoterms are clearly defined; FOB (Free On Board) is generally preferred for buyers who have their own reliable freight forwarders to control costs.
