D.2.3 The use of this substance will not cause environmental pollution. D.2.4 If the natural quantity of a substance is insufficient, consider using chemically synthesized substances with the same properties as the natural substance, such as chemically synthesized pheromones (sex attractants), provided that the use does not directly or indirectly cause pollution to the environment or products. D.3 Evaluation
D.3.1 Significance of evaluation
Regular evaluation of external input substances can make organic production more and more beneficial to humans, animals, the environment and the ecosystem. D.3.2 Criteria for evaluating input materials
Input materials should be comprehensively evaluated from the aspects of crop yield, quality, environmental safety, ecological protection, landscape, living conditions of humans and animals, etc. Input materials are restricted to special crops (especially perennial crops), specific regions and specific conditions. D.3.3 Sources and production methods of input materials D.3.3.1 Input materials should generally come from (in order of priority) organic matter (plants, animals, microorganisms), minerals, and chemically synthesized substances equivalent to natural products. Renewable input materials should be given priority, followed by mineral source materials, and finally input materials with chemical properties equivalent to natural products. When allowing the use of chemically equivalent input materials, it is necessary to consider its ecological, technical or economic reasons. D.3.3.2 The ingredients of input materials can be mechanically treated, physically treated, enzymatically treated, treated by microbial action, and chemically treated (as an exception and subject to restrictions).
D.3.3.3 When collecting raw materials for input materials, the stability of the natural environment shall not be affected, nor shall the survival of any species in the collection area be affected.
D.3.4 Environmental impacts
D.3.4.1 Input materials shall not harm the environment, such as causing pollution to surface water, groundwater, air and soil. The impact of these substances on the environment during processing, use and decomposition must be evaluated. D.3.4.2 Input materials can be degraded into carbon dioxide, water and other mineral forms. There is no prescribed degradation time limit for non-toxic natural input materials.
U.3.4.3 The half-life of input materials with high acute toxicity to non-target organisms shall not exceed 5 days, and their use shall be restricted, such as stipulating the maximum allowable use amount. If measures cannot be taken to ensure the survival of non-target organisms, the input material shall not be used. D.3.4.4 Input materials that accumulate in organisms or biological systems shall not be used, nor shall input materials that are known or suspected to be mutagenic or carcinogenic be used.
D.3.4.5 Input materials should not contain harmful chemical synthetic substances (xenobiotics). Chemical synthetic products are only allowed to be used when their properties are exactly the same as those of natural products. D.3.4.6 The heavy metal content of input minerals should be as low as possible. The use of copper in any form must be considered temporary and must be limited. D.3.5 Human health and product quality
D.3.5.1 Input materials must have no effect on human health. It must be considered whether the input materials are harmful during processing, use and degradation. Some measures should be taken to reduce the risk of using input materials and establish standards for the use of input materials in organic tea. D.3.5.2 Input materials should have no adverse effects on product quality such as taste, shelf life and appearance quality. D.3.5.3 Ethics and confidence
D.3.5.3.1 Input materials should have no adverse effects on the natural behavior or body functions of farmed animals.
