IV. Label size should not be smaller than 148 mm × 210 mm for volume over 500 liters.
Due to the size, or shape, or material used for the container or packaging for toxic and concerned chemical substances, the labels may have difficulty meeting the prescription above, in which case fold-out labels, tie-on tags or outer packaging should be used instead and put on a conspicuous place. The size of such label does not subject to the preceding paragraph.

Manufacturers and importers should mark clearly on each container or
packaging the toxic and concerned chemical substances. Purchasers should keep the clarity and integrity of labeling content of each container or package.

The user should label the containers or packaging of toxic and concerned chemical substances that are individually packaged or mixed for self-use as prescribed in Article 3.
When, in the preceding paragraph, the same toxic and concerned chemical substances are contained in several containers or packages in the same location, a placard may replace the individual labels as prescribed in Article 9.

When any one of the following situations is applied, the containers or packaging of toxic and concerned chemical substances may be exempted from the prescription in Article 3:
I. When the outer container or packaging is already labeled and the inner container or packaging is used only as lining and not subsequently removed.
II. When the inner container or packaging is already labeled clearly and also easily seen from the outer container or packaging.
III. Toxic and concerned chemical substances are taken from marked containers or packaging and immediately used solely by the team currently on duty.
IV. Toxic and concerned chemical substances are taken from marked containers or packaging and used by a laboratory for experiment or research on a self-use basis.
