Green coffee

When evaluating green coffee, you must prioritize moisture content, which should ideally be between 10% and 12% to prevent mold growth or quality degradation. Additionally, check the defect count based on SCAA (Specialty Coffee Association of America) standards; high-quality beans should have zero primary defects (like black or sour beans). The bean size (Screen Size) is also critical for roasting consistency, with Screen 17/18 being the standard for premium grades.

To ensure smooth customs clearance and meet consumer demand, look for Phytosanitary Certificates issued by the exporting country's plant protection organization. For specific market segments, Organic (USDA or EU Organic), Fair Trade, and Rainforest Alliance certifications are vital. Ensure the supplier provides a Certificate of Origin to benefit from potential tariff preferences under trade agreements.

The processing method—Washed (Wet), Natural (Dry), or Honey processed—drastically changes the flavor profile and shelf life. Washed beans offer higher acidity and clarity, preferred for premium specialty roasts, while Natural processed beans provide heavier body and sweetness. For B2B buyers, Washed process beans are often more stable for long-term storage and large-scale industrial roasting.

Green coffee is hygroscopic and absorbs odors. Suppliers should use GrainPro or Ecotact liners inside traditional jute bags to provide a hermetic barrier against moisture and pests. The warehouse should maintain a controlled temperature (15-20°C) and humidity (50-60%) to prevent the beans from 'fading' or losing their enzymatic vitality.

The biggest risks include quality inconsistency between samples and bulk shipments and moisture damage during sea transit. To mitigate this, always use Third-Party Inspection services (like SGS) to verify the cargo at the loading port. Ensure the contract specifies allowable defect percentages and use Letter of Credit (L/C) or Escrow services to secure payment until shipping documents are verified.

Coffee is a commodity priced against the New York (C Market) or London exchange. Negotiate based on a 'Differential' (premium or discount) over the market price. For shipping, FOB (Free On Board) is recommended for experienced buyers to control freight costs, but ensure the supplier uses Food-Grade containers and avoids placing coffee near odorous goods like rubber or chemicals.

Buyers must be aware of Maximum Residue Limits (MRLs) for pesticides. For example, the EU and USA have strict testing for Ochratoxin A (OTA). Always request a Lab Analysis Report from the supplier before the ship sails. On platforms like Made-in-China.com, prioritize Audited Suppliers who have a proven track record of exporting to your specific region to ensure they understand local food safety laws.

Utilize the secured payment systems provided by reputable B2B platforms like Made-in-China.com to ensure funds are only released upon proof of shipment (Bill of Lading). Conduct due diligence by checking the supplier's business license, export permit, and years of operation. Requesting a small trial order (e.g., 10-20 bags) before committing to a full container load (FCL) is a standard industry safeguard.
