Peanut shell

Peanut shells are highly versatile raw materials. In the bioenergy sector, they are processed into fuel pellets due to their high calorific value. In agriculture, they serve as animal bedding (poultry litter), organic mulch, or a component in mushroom cultivation substrates. Additionally, they are used in wastewater treatment as a low-cost biosorbent for heavy metals and in the construction industry for creating particleboard or fiberboard.

Buyers must focus on Moisture Content, which should ideally be below 10-12% to prevent mold growth during transit. Purity levels are critical; ensure the shells are free from stones, soil, and metallic debris. For fuel applications, verify the Ash Content (lower is better) and Calorific Value. If used for animal feed or bedding, testing for Aflatoxin levels and pesticide residues is mandatory to meet safety standards.

Peanut shells are typically supplied in three forms: Whole Shells, which are bulky and used for mulch; Crushed/Ground Shells, often used for furfural extraction or bedding; and Pelletized Shells, which are densified for efficient logistics and primarily used as industrial biomass fuel.

As a plant-based byproduct, peanut shells often require a Phytosanitary Certificate issued by the exporting country's national plant protection organization. For entry into markets like the EU or USA, compliance with Fumigation requirements (e.g., Methyl Bromide treatment) is often necessary to prevent the spread of invasive pests. Ensure the supplier provides a Certificate of Origin and a Analysis Report (COA).

Peanut shells have a low bulk density, which can make shipping expensive. To optimize costs, buyers should source compressed bales or pelletized forms to maximize container weight utilization. Utilizing High Cube (HC) containers and negotiating FOB (Free On Board) terms allows the buyer to maintain better control over freight forwarding and local logistics costs.

The primary risks include moisture damage (sweating) during sea transit and regulatory rejection due to pests. To secure the transaction, use Trade Assurance or Letters of Credit (L/C). It is highly recommended to hire a third-party inspection agency (like SGS or Intertek) to perform a Pre-Shipment Inspection (PSI) to verify weight, moisture, and packaging integrity.

When sourcing via Made-in-China.com, look for Audited Suppliers with verified production capacities. Negotiate based on volume-based pricing tiers; for agricultural waste, a long-term supply contract often yields a 10-15% discount compared to spot purchases. Always request a pre-production sample to verify the grinding size or pellet density before committing to a full container load.

Upon arrival, peanut shells must be stored in a cool, dry, and well-ventilated warehouse. Because they are flammable, fire safety protocols and dust explosion prevention measures (if handling ground shells) must be strictly implemented. Ensure the storage area is pest-controlled to prevent infestation of the bulk material.
