Peanut in shell

When sourcing peanuts in shell, buyers must focus on physical integrity and moisture content. The shells should be bright, clean, and free from dark spots or mold, which indicates proper drying. The moisture level must be strictly controlled below 9% to prevent the growth of Aflatoxin, a carcinogenic mold common in poorly stored legumes. Additionally, the kernel-to-shell ratio should be high, typically aiming for a 70/30 or 75/25 split to ensure economic value.

Compliance is critical due to food safety regulations. Buyers must ensure suppliers provide Phytosanitary Certificates issued by national plant protection organizations. For the EU market, adherence to maximum residue levels (MRLs) for pesticides and strict Aflatoxin limits (B1 < 2.0 μg/kg) is mandatory. For the US, FDA registration and compliance with the Food Safety Modernization Act (FSMA) are required. Always request HACCP or ISO 22000 certifications to verify the supplier's food safety management system.

The variety determines the end-use: Virginia peanuts are known for their large size and are preferred for gourmet snacking and roasting in-shell. Runner peanuts are more uniform and often used for commercial roasting, while Spanish peanuts have a higher oil content, making them ideal for oil extraction or peanut butter. Pricing fluctuates based on caliber (count per ounce); for example, 9/11 or 11/13 counts are premium sizes that command higher market prices compared to smaller grades.

A top-tier supplier should utilize optical sorting technology (CCD sorters) to remove damaged or discolored shells that manual labor might miss. The drying process is equally vital; mechanical hot-air drying is preferred over sun-drying to ensure uniform moisture reduction and reduce environmental contamination. Ensure the supplier uses aspiration systems to remove dust, stones, and foreign metallic objects during the cleaning phase.

The biggest risk is quality degradation during transit, specifically mold growth due to temperature fluctuations (the 'container sweat' effect). To mitigate this, use desiccants (silica gel bags) inside the container and ensure the use of ventilated containers if the voyage exceeds 21 days. Another risk is weight loss due to natural moisture evaporation; buyers should negotiate a weight tolerance clause (usually 1-3%) in the sales contract.

For new suppliers, avoid 100% T/T upfront. Use Letter of Credit (L/C at sight) or Escrow services provided by reputable platforms like Made-in-China.com to ensure payment is only released upon proof of shipment. For bulk agricultural commodities, it is standard to pay 30% deposit and 70% against a scanned copy of the Bill of Lading (B/L), provided a third-party inspection (like SGS or CCIC) has verified the quality at the loading port.

Peanuts are bulky; therefore, 40ft High Cube (HC) containers are usually the most cost-effective. Ensure the packaging is breathable, such as PP woven bags or jute bags, to allow air circulation. Avoid shipping during the monsoon or high-humidity seasons if possible. Always verify the 'Free Time' at the destination port; agricultural products often face longer customs clearance times for quarantine inspections, so negotiating 14-21 days of free detention is highly recommended.
