iDevelopment of the East African Standards has been necessitated by the need for harmonizing requirements governing quality of products and services in East Africa. It is envisaged that through harmonized standardization, trade barriers which are encountered when goods and services are exchanged within the Community will be removed.
In order to meet the above objectives, the EAC Partner States have enacted an East African Standardization, Quality Assurance, Metrology and Test Act, 2006 (EAC SQMT Act, 2006) to make provisions for ensuring standardization, quality assurance, metrology and testing of products produced or originating in a third country and traded in the Community in order to facilitate industrial development and trade as well as helping to protect the health and safety of society and the environment in the Community.
East African Standards are formulated in accordance with the procedures established by the East African Standards Committee. The East African Standards Committee is established under the provisions of Article 4 of the EAC SQMT Act, 2006. The Committee is composed of representatives of the National Standards Bodies in Partner States, together with the representatives from the private sectors and consumer organizations. Draft East African Standards are circulated to stakeholders through the National Standards Bodies in the Partner States. The comments received are discussed and incorporated before finalization of standards, in accordance with the procedures of the Community.
Article 15(1) of the EAC SQMT Act, 2006 provides that “Within six months of the declaration of an East African Standard, the Partner States shall adopt, without deviation from the approved text of the standard, the East African Standard as a national standard and withdraw any existing national standard with similar scope and purpose”.
East African Standards are subject to review, to keep pace with technological advances. Users of the East African Standards are therefore expected to ensure that they always have the latest versions of the standards they are implementing.

For the purpose of this East African Standard, the following definitions shall apply.
whole mature dry seeds of varieties (Glycine max (L.) Merr.)
1Soybeans may be yellow, green, brown or black.
soybeans and pieces of soybeans that are badly ground-damaged, badly weather-damaged, diseased, frost-damaged, germ-damaged, heat-damaged, insect-bored, mould-damaged, sprout-damaged, stinkbug-stung, or otherwise materially damaged. Stinkbug-stung kernels are considered damaged kernels at the rate of one-fourth of the actual percentage of the stung kernels.
any extraneous matter than dry soybeans or other food grains comprising of
immature damaged soybeans are characterized by a green exterior appearance in conjunction with green discolouration penetrating the cotyledon. Examination of the cotyledons is determined by cutting the soybeans in cross section. For grading purposes, immature damaged soybeans are considered as part of the “Total Damage” grade specification. Soybeans that are green in appearance and have no discolouration of the cotyledon or just a halo of green around the outside of the cotyledon are to be assessed against the overall colour of the sample.
any seed which if present in quantities above permissible limit may have damaging or dangerous effect on health, organoleptic properties or technological performance such as Jimson weed — dhatura (D. fastuosa Linn and D. stramonium Linn.) corn cokle (Agrostemma githago L., Machai Lallium remulenum Linn.) Akra (Vicia species), Argemone mexicana, Khesari and other seeds that are commonly recognized as harmful to health
Soybeans in various stages of rancidity are characterized by a deep pink discolouration on the seed coat and varying degrees of discolouration of the cotyledon.
broken soybean seeds that are less than three-quarters of the whole seed, and cotyledons that are loosely held together by the seed coat.
Soybeans shall meet the following general requirements/limits as determined using the relevant standards listed in Clause 2:
Soybeans shall be graded into three grades on the basis of the tolerable limits established in Table 1 which shall be additional to the general requirements set out in this standard.
Shall be soybeans which do not fall within the requirements of Grades 1, 2, and 3 of this standard but are not rejected soybeans.
Note: For Tanzania and Burundi this requirement shall not apply.
This comprises soybeans which have objectionable odour, off flavour, living insects or which do not possess the quality characteristics specified in Table 1. They cannot satisfy the conditions of ungraded soybeans and shall be graded as reject soybeans and shall be regarded as unfit for human consumption.

Soybeansshall comply with those maximum limits for heavy metals established by the Codex Alimentarius Commission for this commodity.
3Soybeans shall comply with those maximum pesticide residue limits established by the Codex Alimentarius Commission for this commodity
Note: where the use of certain pesticides is prohibited by some Partner States, then it shall be notified to all Partner States accordingly.
Soybeans shall comply with those maximum mycotoxin limits established by the Codex Alimentarius Commission for this commodity. In particular, total aflatoxin levels in soybeans for human consumption shall not exceed 10 µg/kg (ppb) with B1 not exceeding 5 µg/kg (ppb) when tested according to ISO 16050.
Soybeans shall be produced, prepared and handled in accordance with the provisions of appropriate sections of EAS 39

Soybeans shall be packed in suitable packages which shall be clean, sound, free from insect, fungal infestation and the packing material shall be of food grade quality.
Soybeans shall be packed in containers which will safeguard the hygienic, nutritional, technological and organoleptic qualities of the products.
The containers, including packaging material, shall be made of substances which are safe and suitable for their intended use. They shall not impart any toxic substance or undesirable odour or flavour to the product.
Each package shall contain soybeans of the same type and of the same grade designation.
If soybeans are presented in bags, the bags shall also be free of pests and contaminants.
Each package shall be securely closed and sealed.
4In addition to the requirements in EAS 38, each package shall be legibly and indelibly marked with the following:
Note: EAC partner states are signatory to the International Labour Organizations (ILO) for maximum package weight of 50 kg where human loading and offloading is involved
Sampling shall be done in accordance with the EAS 79/ISO 13690.
