2.1.10. HS codes of fertilizers are specified in Section 1 in the Appendix I to the Circular No. 01/2024/TT-BNNPTNT dated February 02, 2024 of the Minister of Agriculture and Rural Development.

2.2. Requirements for fertilizer quality indexes

A fertilizer must meet main quality indexes and additional quality indexes to be registered in the decision to recognize circulation of fertilizer in Vietnam or fertilizer import license (hereinafter referred to as “additional quality indexes to be registered”), acceptable deviations between test results and registered limits in the decision to recognize circulation of fertilizer in Vietnam or fertilizer import license (hereinafter referred to as “deviations from registered limits”) and acceptable deviations between test results and prescribed limits (hereinafter referred to as “deviations from prescribed limits”) applicable to the quality indexes specified in Appendices I, II and III to this Regulation.

Apart from main quality indexes and additional quality indexes to be registered, organizations and individuals are entitled to register additional quality indexes specified in Table 24 of the Appendix II to this Regulation in the decision to recognize circulation of fertilizer in Vietnam (hereinafter referred to as “registered additional quality indexes”).

If a fertilizer contains one or more PGRs whose content or total content is > 0.005% by mass (or > 50 mg/kg or > 50 ppm by mass), such PGRs must be registered in the decision to recognize circulation of fertilizer in Vietnam or fertilizer import license; the content or total content (in case of more than two PGRs) of PGRs in the fertilizer must be less than 0,5% by mass.

In the case of a fertilizer with quality indexes possessing specific properties, such specific properties must be registered, recognized and indicated in the decision to recognize circulation of fertilizer in Vietnam or fertilizer import license.

The fertilizer quality indexes specified in the declaration of conformity must be consistent with those specified in the decision to recognize circulation of fertilizer in Vietnam.

2.3. Restricted elements in fertilizers (harmful elements)

Fertilizers must satisfy the requirements concerning restricted elements specified in the Appendix IV to this Regulation. Restricted elements and their content in urea fertilizers, ammonium sulphate fertilizers, ammonium chloride fertilizers, fused phosphate fertilizer, single superphosphate fertilizer, double superphosphate fertilizer, enriched superphosphate fertilizer, diammonium phosphate fertilizer, urea and micronutrient fertilizer, ammonium and micronutrient sulphate fertilizer, ammonium chloride and micronutrient fertilizer, fused phosphate and micronutrient fertilizers, single superphosphate and micronutrient fertilizers, double superphosphate and micronutrient fertilizers, enriched superphosphate and micronutrient fertilizers, and diammonium phosphate and micronutrient fertilizers must be registered in the decision to recognize circulation of fertilizer in Vietnam in accordance with the provisions set out in the Appendix IV to this Regulation and the declaration of their conformity must include the restricted elements specified in the decision to recognize circulation of fertilizer in Vietnam.

Fertilizers must not contain active substances of plant protection products. If fertilizers contain a biological substance which provides nutrients to plants or improves soil and also controls harmful organisms, they must be registered and considered and recognized by the competent authority in the decision to recognize circulation of fertilizer in Vietnam or fertilizer import license with respect to each specific fertilizer.

3. TEST METHODS

3.1. Sampling

3.2. Test methods

3.2. Conformity assessment bodies may apply other test methods which have equivalent accuracy and designated or accredited by the competent authority in accordance with law on standards and technical regulations.

For dated TCVN on test methods, only the edition cited applies when reviewed. If there are factors affecting the test results because a method specified in TCVN has not been reviewed and revised to make it suitable to the practical situation or no test methods specified in this Regulation are tailored for quality indexes (including quality indexes having specific properties) and restricted elements in fertilizers, the test method designated or accredited by the competent authority in accordance with the law on standards and technical regulations shall apply.

Foliar fertilizers shall be classified according to the main quality indexes registered in the decision to recognize circulation of fertilizer in Vietnam into one of the following three groups of fertilizers, namely inorganic foliar fertilizers, organic foliar fertilizers and foliar biofertilizers.

The main quality indexes of foliar fertilizers are those registered in the decision to recognize circulation of fertilizer in Vietnam as specified in Table 25 of this Appendix.

The additional quality indexes to be registered for foliar fertilizers shall be moisture, pHH2O for solid foliar fertilizers; density (specific gravity) and pHH2O for liquid foliar fertilizers; moisture, pHH2O and C/N ratio for solid foliar fertilizers, or density (specific gravity), pHH2O and C/N ratio for liquid foliar fertilizers having organic substance as a main quality index, and such index shall be registered in the decision to recognize circulation of fertilizer in Vietnam.

The specified limits of main quality indexes, additional quality indexes to be registered for foliar fertilizers shall be those registered by the organization or individual having fertilizers and recognized in the decision to recognize circulation of fertilizer in Vietnam for each specific fertilizer.

Acceptable deviations from registered limits applicable to main quality indexes and additional quality indexes to be registered for foliar fertilizers are specified in Tables 25 and 26 of this Appendix.
