Longjing tea manufacturers

Authentic West Lake Longjing is strictly produced within the designated 168 square kilometer area in Hangzhou. Buyers should look for the Geographical Indication (GI) protection label and a traceability QR code issued by the local government. Visually, high-quality Longjing features flat, smooth, and straight leaves with a 'brownish-yellow' tint (often called 'rice gold'), rather than a bright artificial green. The aroma should be a distinctive nutty or chestnut fragrance that lingers after brewing.

Longjing is categorized into grades: Superior (Te Ji), Grade 1, Grade 2, and so on. The highest quality is harvested Pre-Qingming (before April 5th), known for its tenderness and sweetness, while Pre-Guyu (before April 20th) offers a stronger flavor and better value for mass distribution. Ensure the supplier provides a Product Standard Number (GB/T 18650), which is the national standard for Dragon Well Tea.

For international trade, the supplier must provide a Phytosanitary Certificate and a Certificate of Origin. Depending on the destination country, you should verify Pesticide Residue Test Reports (meeting EU MRLs or US FDA standards). Prioritize suppliers with HACCP, ISO 22000, or Rainforest Alliance certifications to ensure processing hygiene and ethical sourcing.

Tea is highly sensitive to light, moisture, and odors. For B2B shipping, ensure the tea is vacuum-sealed in aluminum foil bags and placed in moisture-proof tin cans or reinforced cartons. For long-term storage, the tea must be kept in a cold storage environment (0-5°C). If purchasing for retail, ensure the packaging complies with labeling laws in your target market, including net weight, ingredients, and expiration dates.

The primary risk is 'adulteration' or 'origin fraud,' where tea from outside the West Lake area is sold as premium Longjing. To mitigate this, use Made-in-China.com's 'Audit Verified' supplier service to check the supplier's factory location and business scope. Another risk is seasonal price volatility; it is recommended to lock in prices via forward contracts before the spring harvest begins.

Request a 'Pre-shipment Sample' (PSS) that represents the actual mass production batch, not just a high-end showroom sample. Include a clause in your contract stating that the bulk goods must match the PSS sensory profile. For large orders, negotiate a staged payment plan (e.g., 30% deposit, 70% after third-party inspection) to maintain leverage.

For high-value Pre-Qingming tea, Air Freight is strongly recommended to minimize transit time and exposure to heat. For larger, lower-grade shipments, Sea Freight with Reefer Containers (refrigerated) is ideal. Always ensure the bill of lading specifies 'Keep away from heat and odors' to prevent cross-contamination with other cargo.

Always conduct transactions through secure payment channels provided by reputable B2B platforms like Made-in-China.com, which offer escrow-like services. Avoid direct wire transfers to private accounts. Additionally, consider hiring a third-party inspection agency (like SGS or Intertek) to perform a loading supervision to verify quantity and packaging integrity before the container is sealed.
