Crab

For live crabs, check for high activity levels and strong limb movement; they should feel heavy for their size, indicating full meat content. For frozen products, ensure there are no signs of freezer burn or ice crystals inside the packaging, which suggests temperature fluctuations. Meat yield (filling rate) is a critical KPI; premium suppliers should guarantee a filling rate of 80% or higher during peak seasons.

Suppliers must provide HACCP (Hazard Analysis and Critical Control Point) certification and ISO 22000 for food safety. Depending on the destination country, you may require a Health Certificate, Certificate of Origin, and Catch Certificate to prove the product was legally harvested. Ensure the supplier complies with FDA (USA) or EFSA (EU) regulations regarding heavy metal limits (like cadmium and mercury) and biotoxins.

Specify the grade of meat required: Colossal Lump, Jumbo Lump, Backfin, or Claw meat. Confirm the pasteurization process parameters to ensure shelf-life stability. For frozen crab, clarify the glazing percentage (net weight vs. gross weight); a standard glazing of 10-20% is common, but it must be clearly documented to avoid overpaying for water.

Crab quality and pricing are highly seasonal. Buyers should align their procurement calendars with the molting cycles and harvest seasons of specific species (e.g., King Crab, Snow Crab, or Blue Swimmer Crab). Purchasing during the peak harvest ensures the lowest unit price and highest meat density. Establish long-term contracts with suppliers on Made-in-China.com to secure stable supply during the off-season.

The biggest risks are Cold Chain Failure and Customs Delays. Seafood is highly perishable; a break in the -18°C (for frozen) or 2-4°C (for live) cold chain can lead to total cargo loss. Always use dataloggers in containers to monitor temperature throughout transit and ensure the supplier has adequate export quotas to prevent seizures at the border.

For beginners, CIF (Cost, Insurance, and Freight) is often preferred as the seller manages the complex refrigerated logistics. However, experienced buyers may prefer FOB (Free on Board) to have better control over the shipping line's transit time. Always negotiate a 'Dead on Arrival' (DOA) allowance for live shipments, typically ranging from 3% to 5%.

Utilize secure payment terms such as Letter of Credit (L/C) or Escrow services provided by reputable platforms like Made-in-China.com. Never wire full payments upfront to unverified suppliers. Request a third-party pre-shipment inspection (PSI) from companies like SGS or Intertek to verify weight, count, and temperature before the container is sealed.

Ensure all labeling and marking comply with the destination country's laws, including scientific names (Latin names), production dates, and storage instructions. Work with a specialized customs broker who has experience in perishable goods to expedite the release process and avoid costly demurrage charges at the port.
