Fertilizers offered for sale or intended for sale, when displayed or stored, must not be unsealed, repackaged, mixed, diluted, or have their fertilizer labeling altered. But fertilizer manufacturers or importers are exempt from these restrictions while manufacturing, processing, and packaging fertilizers.

Fertilizers with one of the following conditions shall not be displayed or stored for sale or intended for sale:
1.Those without a fertilizer registration certificate;
2.Those of unknown origins;
3.Those not packaged or labeled in compliance with this Act; and
4.Those with poor qualities.
The term "poor quality" as mentioned in subparagraph 4 of the preceding Paragraph refers to those that do not meet the registered ingredients or the specifications announced in accordance with Article 4.

Those who publish fertilizer advertisements shall include the fertilizer registration certificate number, item number, and registered ingredients, and are prohibited from engaging in false, exaggerated, and other inappropriate advertising practices.

Items not complying with the fertilizer specifications presecibed and announced by the Central Competent Authority in accordance with Article 4 may not be labeled, advertised, or promoted with the name of the fertilizer or with claims of having fertilizer effects.
