Chinese tiger nut

When evaluating Tiger Nuts (Cyperus esculentus), buyers should prioritize size uniformity, moisture content, and cleanliness. High-quality nuts typically have a moisture level below 10% to prevent mold during transit. Look for a golden-brown exterior without dark spots or shriveling. For food processing, ensure the starch content is high (20-30%) and the natural oil content is around 20-25%, which are critical for milk (Horchata) production and oil extraction.

As an agricultural product, compliance is non-negotiable. Suppliers must provide Phytosanitary Certificates issued by customs authorities. For entry into the US or EU, HACCP, ISO 22000, or BRC certifications are highly recommended. If the product is marketed as a health food, verify Organic Certifications (USDA or EU Organic) and ensure the product is Non-GMO verified. Always request a COA (Certificate of Analysis) covering heavy metals, pesticide residues, and aflatoxin levels.

Tiger nuts are available in three primary forms: Dried Whole Nuts, Peeled (Skinless) Nuts, and Flour. Dried whole nuts are best for long-term storage and oil pressing. Peeled tiger nuts are preferred for direct snacking and premium milk production as they yield a smoother texture. Tiger nut flour is a growing trend in the gluten-free baking industry; ensure the flour is extra-fine (mesh size >60) to maintain high-end product consistency.

China has significantly expanded its cultivation areas (notably in Hebei and Xinjiang), offering competitive pricing due to mechanized harvesting and large-scale processing. Buyers can achieve cost savings of 15-25% compared to African or Spanish origins when ordering in bulk. To maximize ROI, aim for Full Container Loads (FCL) to reduce per-unit shipping costs and negotiate tiered pricing where the unit price drops significantly at the 5-ton and 10-ton thresholds.

The biggest risks are moisture damage and pest infestation during sea freight. To mitigate this, insist on vacuum packaging or moisture-proof PP bags with desiccant. Use Third-Party Inspection services (like SGS or Intertek) to conduct pre-shipment inspections at the supplier's warehouse to verify that the batch matches the approved sample in terms of size grade and purity.

For new partnerships, utilize Trade Assurance or Letters of Credit (L/C) to ensure payment is only released upon proof of shipment. A standard payment structure is 30% T/T deposit and 70% against the Bill of Lading (B/L) copy. Always verify the supplier's business license and export qualifications on Made-in-China.com to ensure you are dealing with a verified manufacturer rather than an unlicensed middleman.

For bulk agricultural commodities, Sea Freight (FCL) is the standard. Ensure the container is a Dry Van with proper ventilation or, for high-value peeled nuts, consider a Reefer Container set at 5-10°C if the transit time exceeds 30 days. Ensure the supplier provides a Packing List and Commercial Invoice that strictly matches the HS Code (typically 1212.99) to avoid customs delays and additional storage fees.
