Dried herbs

When evaluating dried herbs, prioritize color retention, aroma intensity, and moisture content. High-quality dried herbs should retain a vibrant color close to their fresh state; dull or brown leaves often indicate oxidation or improper drying. The moisture content must be strictly controlled between 8% and 12% to prevent mold growth while avoiding brittleness. Additionally, ensure the volatile oil content meets pharmacopoeia or food industry standards, as this directly impacts the flavor and therapeutic efficacy.

Compliance is critical due to food safety regulations. Buyers should verify that suppliers hold ISO 22000 or HACCP certifications for food safety management. For the US market, FDA registration and compliance with the FSMA (Food Safety Modernization Act) are required. For the EU, products must adhere to EC No 396/2005 regarding maximum residue levels (MRLs) for pesticides. If sourcing organic herbs, look for USDA Organic or EU Organic certifications to ensure no synthetic chemicals were used during cultivation.

Inquire whether the supplier uses Air Drying, Freeze-Drying (Lyophilization), or Dehydration. Freeze-drying is the premium choice for preserving heat-sensitive nutrients and complex aromas, though it carries a higher cost. For bulk industrial use, controlled mechanical dehydration is more common. Ensure the supplier utilizes metal detectors and air-cleaning systems during processing to remove foreign physical contaminants like stones, glass, or plastic.

Dried herbs are highly sensitive to light, oxygen, and moisture. Professional suppliers should use multi-layer vacuum-sealed bags, aluminum foil bags, or UV-protected containers. For bulk shipments, double-walled corrugated boxes with moisture-proof liners are essential. Ensure each batch is labeled with a Batch Number, Production Date, and Expiry Date to maintain full traceability throughout the supply chain.

Always request a Certificate of Analysis (COA) for every batch before shipment. This report should specifically detail levels of lead, cadmium, mercury, and arsenic, as well as a comprehensive pesticide residue screen. For large orders, it is highly recommended to hire a third-party inspection agency like SGS or Intertek to perform random sampling at the factory before the balance payment is made.

Focus on transparency and long-term partnership. Start by requesting a small sample (500g - 1kg) to verify quality. When negotiating, discuss tiered pricing based on volume—discounts of 10-20% are often available for container-load orders. Clarify the Incoterms (typically FOB or CIF) and ensure the supplier is experienced with the specific phytosanitary certificate requirements of your destination country to avoid customs delays.

Utilize secure payment methods provided by reputable platforms like Made-in-China.com, which offer trade fulfillment services. Avoid direct wire transfers to private accounts. Ensure the Proforma Invoice (PI) clearly states the specifications, including purity levels (e.g., 99% Purity) and allowable moisture percentages. This documentation serves as your primary protection in case of a quality dispute.

For long-distance sea freight, especially through tropical zones, use reefer containers (refrigerated) or humidity-controlled containers if the herbs are high-value or highly volatile. Ensure the cargo is stowed away from heat sources on the vessel. For smaller shipments, Air Freight is preferred to minimize the time the product spends in fluctuating environmental conditions, thereby preserving the essential oil profile.
