Lychee fruit

When sourcing fresh lychee, the skin color should be vibrant red or pinkish-red; brown spots usually indicate oxidation or old age. The texture must be firm to the touch, as softness suggests internal fermentation. For B2B buyers, the Brix level (sugar content) should ideally be between 17% and 22% to ensure premium taste. Additionally, check for uniformity in size and ensure the stems are still attached to prevent rapid moisture loss.

The most commercially viable varieties include 'Feizixiao' (Greenish-red skin, small seeds, high flesh ratio), which is known for its early harvest and excellent transportability. 'Baitangying' is preferred for its extreme sweetness, while 'Huai Zhi' is often used for processing and canning due to its thicker skin. For high-end retail, 'No Mai Tsze' (Glutinous Rice Cake) is the gold standard due to its shriveled 'chicken tongue' seeds and superior fragrance.

Suppliers must provide Phytosanitary Certificates issued by the exporting country's national plant protection organization. Products must adhere to MRL (Maximum Residue Limits) for pesticides as defined by the destination country (e.g., EPA for the US, EFSA for the EU). Ensure the supplier is GlobalG.A.P. certified to guarantee good agricultural practices and food safety traceability. For the US market, Cold Treatment or Irradiation protocols may be required to mitigate fruit fly risks.

Lychee is highly perishable and requires a strict cold chain at 2°C to 5°C with a relative humidity of 90-95%. Packaging should involve perforated polyethylene bags or plastic clamshells within corrugated master cartons to balance moisture retention and ventilation. To prevent browning (pericarp browning), some suppliers use sulfur dioxide (SO2) fumigation or acid dips, though you must verify if these treatments are permitted by your local food authority.

The biggest risk is Cold Chain Breach, which can lead to a total loss of cargo within 48 hours. Another risk is Customs Clearance Delays due to incomplete phytosanitary documentation. To mitigate this, always use refrigerated containers (Reefers) equipped with real-time GPS and temperature sensors, and ensure all paperwork is pre-cleared by a specialized customs broker.

Focus on Quality-Linked Pricing. Instead of just negotiating the unit price, set a claim threshold for spoilage (e.g., if more than 5% of the fruit arrives browned or moldy, a pro-rata refund applies). For large volumes, request FOB (Free On Board) terms if you have a reliable logistics partner, or CIF (Cost, Insurance, and Freight) if you want the supplier to bear the transit risk to your port.

For premium markets where freshness is paramount, Air Freight is the preferred method, typically reaching the destination within 24-72 hours. For larger volumes and cost-efficiency, Sea Freight in controlled atmosphere (CA) reefer containers is viable for transit times up to 21 days, provided the supplier uses ethylene absorbers and precise temperature management.

Utilize Trade Assurance or Escrow services provided by reputable platforms like Made-in-China.com to ensure payment is only released upon proof of shipment. Always request a third-party pre-shipment inspection (e.g., SGS or Intertek) to verify the fruit's grade, temperature at loading, and weight before the balance payment is made.
