1. Grade #2 Yellow Corn: The Industry Benchmark

Standard industry mandates usually follow US Grade No. 2 (or equivalent) for global animal feed distribution.

  • Test Weight: Minimum 54 lbs/bu (~69.5 kg/hl).

  • BCFM (Broken Corn & Foreign Material): Strictly capped at 3.0% to ensure caloric density.

  • Heat Damage: Limited to 0.2% to prevent nutrient loss caused by improper artificial drying.

2. The Silent Killer: Aflatoxin Control

Aspergillus flavus growth in warm, humid regions can produce carcinogenic Aflatoxin (B1/B2/G1/G2).

  • Regulatory Limits:

  • EU Standard: Max 4-20 PPB depending on end-use dairy suitability.

  • US FDA: Max 20 PPB for general livestock consumption.

  • Compliance: Mandatory pre-shipment analysis by SGS/Eurofins for every bulk vessel.

3. Storage & The 14% Moisture Rule

Moisture management is the primary factor in long-haul voyage success.

  • The Threshold: We guarantee Max 14.0% - 14.5% Moisture at loading to prevent mold growth in the humid environment of a ship's hold.

  • Fumigation: Mandatory phosphine (Aluminum Phosphide) treatment to eliminate weevils and infestation risks during transit.

Frequently Asked Questions

What is the aflatoxin limit for yellow corn in international trade?

The maximum acceptable aflatoxin level is 20 PPB (parts per billion) for most markets. Shipments exceeding this threshold are rejected immediately at destination. SGS or equivalent third-party testing at loading port is mandatory for all export-grade corn.

What does Grade #2 Yellow Corn mean?

Grade #2 is the global benchmark for feed corn. Key specs: moisture 14.0–14.5% max, broken kernels 3.0–5.0% max, foreign matter below 2%. It is the standard used in CBOT (Chicago Board of Trade) futures pricing.

Why is moisture content so critical for corn shipments?

High moisture (above 14.5%) creates mold risk during ocean transit, especially on long voyages. Mold produces mycotoxins including aflatoxin, which can cause the entire shipment to be rejected. Moisture is tested at loading and again at discharge.

What are the main origins for yellow corn in global trade?

The United States (Gulf ports), Brazil (Santos/Paranaguá), Ukraine (Odessa/Chornomorsk), and Argentina (Rosario) are the four dominant origins. Black Sea corn is price-competitive but subject to geopolitical supply risk.
