(Excerpt from Article 39 - Crop Law, Law No. 31/2018 / QH14)
General principles on recognition of fertilizers in circulation
1. Fertilizers are goods of conditional trade group which are recognized for circulation in Vietnam.
2. Domestic or foreign organizations and individuals (having representative offices, companies or branches of companies licensed to operate in Vietnam) may register recognition of fertilizers in their names.
3. Each organization or individual may register recognition of only one fertilizer name for each ingredient formula, registered fertilizer nutrient content.
4. The Government shall stipulate the dossiers, order, procedures, time limits and competence to recognize fertilizers circulated in Vietnam.
Principles of testing fertilizers
1. Fertilizers must be subject to testing before being recognized for use, except for the categories of fertilizers stipulated in Clause 2 of this Article.
2. Fertilizers not subject to testing:
a) Organic fertilizers, traditional organic fertilizer used to fertilize roots;
b) Single fertilizers and compound fertilizers, which are used for fertilizing roots and without being supplemented with substances to increase its use efficiency, soil improvers, microorganisms, biological substances, growth regulators or substances to change the nature, utility and use efficiency of fertilizers;
c) Fertilizers are the results of State-level, ministerial-level or provincial-level research projects, which are recognized as technical advances.
3. Fertilizers must be subject to both demonstration and typical testing; demonstration may be conducted only after the end of typical testing.
4. Testing of fertilizers must be subject to approval of the Ministry of Agriculture and Rural Development and carried out at the organizations accredited to be eligible for testing.
5. Testing of fertilizers shall comply with the national standards (the Vietnamese Standards). In the absence of corresponding the Vietnamese Standards, the testing shall be conducted in accordance with the fertilizer testing rules.
