Grain Stability Calculation Form

Grain is a free-flowing cargo that poses significant risks, primarily in the event of cargo shift during a voyage. National Cargo Bureau can assist in mitigating those risks and provide guidance on proper loading, stowage, and carriage of grain cargoes.

National Cargo Bureau is the only entity authorized to issue grain approvals on behalf of the U.S. Administration (ref. 46CFR §172.015) and, as experts in the field, can provide details of regulatory requirements and offer practical assistance in complying with those requirements.

The Grain Code requires that information in printed booklet form be provided to enable the master to ensure that the ship complies with the Code when carrying grain in bulk on an international voyage and details the information to be included in such a Grain Loading Booklet. This Grain Loading Booklet must be approved and identified in the Document of Authorization.

Detailed requirements for preparation of a Grain Loading Booklet are contained within the International Grain Code, International Maritime Organization (IMO) publication No. I240E, obtainable from any authorized IMO publications distributor. Guidance on application of the Grain Code and potential U.S. alternatives can be found in National Cargo Bureau’s publication, “General Information for Grain Loading”.

National Cargo Bureau, Inc. conducts Grain Stability Reviews in conjunction with the issuance of Certificates of Readiness and Certificates of Loading for Bulk Grain. These reviews ensure compliance with the International Grain Code and the applicable sections of 46CFR.

In addition Grain Stability Reviews may be conducted for the following reasons:

  • A preliminary stability review to determine suitability to load grain for chartering purposes.
  • Intermediate stability review during loading when quantities or destinations change.

To complete the review, the National Cargo Bureau Surveyor makes relevant notations on the Grain Stability Calculation and signs his/her name as evidence of the examination.

A Stability Review may be conducted for purposes of a single voyage authorization.
