Coriander seed

When evaluating coriander seeds, focus on purity levels (ideally 98-99%), moisture content (should be below 9%), and essential oil content (typically 0.3% to 1.1%). High-quality seeds should have a uniform light brown to golden color and a distinctive citrusy aroma. Avoid seeds with visible mold, insect damage, or excessive 'splits' unless your specific application (like grinding) allows for them.

Buyers must ensure suppliers comply with Phytosanitary Certification requirements to prevent the spread of pests. For food-grade applications, look for HACCP, ISO 22000, or BRC certifications. Depending on the destination market, you may also require Aflatoxin and Pesticide Residue lab reports to meet FDA (USA) or EFSA (EU) safety limits.

There are two main types: Coriandrum sativum var. vulgare (large seeds) and var. microcarpum (small seeds). The small-seeded variety generally has a higher essential oil content and is preferred for essential oil extraction and high-end spice blends. The larger seeds are more common in general culinary use and pickling due to their milder flavor and ease of grinding.

A top-tier supplier should utilize Sortex (color sorting) technology to remove impurities and discolored seeds. They should also offer steam sterilization or ETO (Ethylene Oxide) treatment to reduce microbial loads (TPC, Yeast, and Mold) to safe levels for international food standards. Verify if they can provide custom grinding (mesh sizes) if you require coriander powder.

The biggest risks are adulteration (mixing old and new crops) and moisture damage during transit. Mitigate these by requesting a Pre-Shipment Inspection (PSI) from agencies like SGS or Bureau Veritas. Ensure the contract specifies the crop year and use silica gel desiccant bags in the container to prevent 'container sweat' during sea freight.

Coriander is a commodity subject to market fluctuations. Negotiate based on volume tiers (e.g., 5, 10, or 20-ton lots). For new suppliers, use Letter of Credit (L/C) or Trade Assurance to secure your funds. For long-term partners, aim for 30% deposit and 70% against scanned BL (Bill of Lading). Always check the latest market price trends on platforms like Made-in-China.com before finalizing.

Coriander seeds should be packed in multi-wall paper bags or PP bags (25kg/50kg) with an inner liner to preserve aroma. For long-distance cross-border shipping, Dry Containers are standard, but they must be clean, dry, and free of odors from previous cargo, as seeds easily absorb external smells. Ensure the HS Code (090921/090922) is correctly declared for customs efficiency.
