1 Scope
This document specifies the terms and definitions related to the classification and
labeling of chemicals, as well as the general requirements for the classification, labeling,
safety data sheets of chemicals.
This document is applicable to the classification and disclosure of chemicals in
accordance with the United Nations Globally Harmonized System of Classification and
Labeling of Chemicals (hereinafter referred to as GHS).
This document does not apply to intentionally ingested drugs, food additives, cosmetics,
pesticide residues in food; however, if workers may be exposed or there is a potential
for exposure during transportation, the provisions of this document must still be
followed.
Note. The labeling requirements for transport packaging shall take precedence over the
requirements of the "Recommendations on the Transport of Dangerous Goods - Model
Regulations".

c) Compare the data with the relevant hazard classification criteria, to decide whether
to classify the substance or mixture as a hazardous substance or mixture;
determine the degree of hazard as appropriate.
4.1.3 Classification criteria
GB 30000.2 ~ GB 30000.29 respectively provide detailed provisions for a specific
hazard class or a group of closely related hazard classes. For most hazard class, the
classification process for mixtures is based on the following sequence.
a) If there is test data for the entire mixture, the classification of the mixture will
always be based on that data;
b) If there is no test data for the mixture itself, consider the bridging principles listed
in GB 30000.2 ~ GB 30000.29 to see if those principles can be used to classify
the mixture. If the test data clearly indicate that no classification is required, the
bridging principles can also be applied;
c) In addition, for health and environmental hazards, if there is no test data for the
mixture itself and the existing information is insufficient to apply the bridging
principles, then the agreed method of estimating the hazard based on the known
information is used to classify the mixture.
Note. In most cases, it is not possible to master the hazard classifications for germ cell
mutagenicity, carcinogenicity and reproductive toxicity for all mixtures. For these hazard
classifications, the mixture is generally classified based on the information on the individual
ingredients in the mixture that has been mastered, using the critical value/concentration limit
method in GB 30000.2 ~ GB 30000.29.The classification can be modified based on the
complete experimental data of the mixture according to the specific situation, provided that the
relevant data is reliable according to the requirements of the above standards.
4.2 Classification of mixtures
4.2.1 Use of critical values/concentration limits
4.2.1.1 When classifying untested mixtures based on the hazards of the ingredients,
some hazard categories use the general critical values/concentration limits of the
classified ingredients of the mixture to classify the mixture. The general critical
values/concentration limits used are sufficient to determine the hazards of most
mixtures, but some mixtures may also contain hazardous ingredients at concentrations
lower than the general critical values/concentration limits, which still pose some
identifiable hazards. There may also be situations where the unified critical
value/concentration limit is much lower than expected based on the determined non-
hazardous level of a certain ingredient.
4.2.1.2 If conclusive data show that the hazard of an ingredient is not apparent above
the general cut-off values/concentration limits adopted in this series of documents, the
mixture may be classified according to these data. The possibility that the ingredients
behave in the mixture in a manner that would increase the hazard compared to the pure
substances shall be excluded. In addition, the mixture shall not contain ingredients that
could affect such a classification decision.
4.2.1.3 Appropriate documentation supporting the use of any values other than the
general cut-off values/concentration limits shall be maintained for review when
required.
4.2.2 Synergistic or antagonistic effects
When classifying a mixture, it should consider all available information on the possible
synergistic effects among the ingredients of the mixture. Downgrading the
classification of a mixture to a less hazardous category based on antagonistic effects
can only be done, if the classification decision is supported by sufficient data.
5 Hazard communication. Chemical safety labels
5.1 Preparation procedure
5.1.1 General procedure
The preparation of chemical safety labels shall comply with the provisions of GB 15258.
The preparation procedure includes.
a) Assignment of label elements;
b) Determination of the order of multiple hazards and information;
c) Arrangement of the display of label elements;
d) Special label arrangements.
5.1.2 Label elements
5.1.2.1 For each hazard category, the normative appendixes on classification and label
elements in GB 30000.2 ~ GB 30000.29 all list in detail the label elements (hazard
symbols, signal words, hazard statements) assigned to each hazard category in Tables.
Hazard categories reflect the standard for unified classification.
Note. "Signal words" are also called "warning words" in some documents.
5.1.2.2 Hazard symbols shall comply with the provisions of Figure 1.
Note. Except for the new symbols to be used for certain health hazards and the exclamation
mark, these symbols are part of a set of standard symbols used in the United Nations
Recommendations on the Transport of Dangerous Goods Model Regulations.
2) The hazard statement code is only for reference and is not part of the hazard
statement text and shall not be used to replace the hazard statement text.
c) Precautionary statements. Precautionary statements shall comply with the
following requirements.
1) Used to describe the measures recommended to minimize or prevent adverse
effects caused by contact with hazardous substances or improper storage or
handling of them. Chemical safety labels shall include appropriate protective
information. GB 30000.2 ~ GB 30000.29 lists the precautionary statements
that can be used for each hazard class.
2) The precautionary statement code is only for reference. This code is not part of
the precautionary statement text and shall not be used to replace the
precautionary statement text.
3) In some cases where the requirements of the competent authorities are followed,
the precautionary statement statements can be combined by using the plus sign
"+" to connect the codes. When the precautionary measures required for
different hazard classes are similar, the precautionary statements can also be
combined.
4) Subject to the requirements of the competent authorities, precautionary
statements on chemical safety labels or safety data sheets may use slightly
different text from that specified in this document, as long as these variations
help convey safety information and do not dilute or detract from the meaning
of the safety advice. Variations may include synonyms or other equivalent
terms applicable to the place where the product is supplied and used. In any
case, precautionary information shall be conveyed in simple and clear
language. In addition, to ensure that the safety information is clear, any text
variations used on the label and the safety data sheet shall be consistent.
d) Pictograms. Pictograms shall comply with the following requirements.
1) Pictograms refer to a graphic composition that may include a hazard symbol
plus other graphic elements, such as borders, background patterns or colors,
used to convey specific information;
2) Pictograms shall be diamonds set at a certain point;
3) Pictograms shall use black symbols on a white background with a red border
that is wide enough to be eye-catching. In the case of domestic use, the border
can be black.
Note. In addition to being used in pictograms, colors can also be used in other areas of the label
to meet special labeling requirements.
statement H318 "Causes serious eye damage" may be omitted.
5.1.5 Arrangement of display of label elements
5.1.5.1 Position of elements on the label
The position of pictograms, signal words, hazard statements on the label shall comply
with the provisions of GB 15258.
5.1.5.2 Supplementary information
Supplementary information that does not violate the relevant provisions of this series
of documents is allowed. The placement of supplementary information shall not hinder
the identification of label element information.
5.1.5.3 Labels for small packages
Small package labels shall meet the following requirements.
a) All applicable chemical safety label content shall be displayed on the container
directly containing the hazardous substance or mixture as much as possible.
b) If it is not possible to place all applicable chemical safety label content on the
direct container, other methods can be used to provide all hazard information. The
main factors affecting this practice include.
1) The shape or size of the direct container;
2) The number of chemical safety label elements that need to be included,
especially when the substance or mixture meets the classification criteria of
multiple hazard categories.
c) If the quantity of the hazardous substance or mixture is small, the supplier has
data to show that it is not likely to harm human health and/or the environment,
meanwhile it has been confirmed that there is no possibility of harming human
health and/or the environment, the label content can be omitted from the direct
container.
d) Subject to compliance with relevant regulations, when the quantity of the
substance or mixture is below a certain amount, certain label content of certain
hazard categories or classifications can be omitted from the direct container.
e) Some label content on the direct container may need to be retained throughout the
life cycle of the product, for example, to facilitate continued use by workers or
consumers.
5.1.6 Special labeling arrangements
5.1.6.1 Principle
For metals and alloys, where they are supplied in a blocky, non-dispersible form, hazard
information can be disclosed only through the material safety data sheet, subject to
compliance with relevant regulations. When the substance or mixture is classified as
corrosive to metals but not corrosive to skin and/or eyes, the hazard pictogram related
to "metal corrosives" can be omitted from the label of the final product in good
packaging for consumer use, subject to compliance with relevant regulations.
5.1.6.2 Labeling in the workplace
Chemicals within the scope of this document shall be labeled appropriately when
provided to the workplace. Labeling requirements shall be implemented in accordance
with GB/T 30000.31.In the workplace, labels shall always remain on the containers
provided. If there is a form that is more suitable for the workplace and can effectively
publicize chemical information, alternative means are allowed to provide the same
information to workers in different written or displayed formats. For example, label
information can be displayed in the work area instead of on individual containers.
5.1.6.3 Consumer product labeling based on the possibility of injury
Subject to the relevant regulations, consumer products (i.e., goods that can be purchased
directly on the market by the general public) can use a consumer product labeling
system, that provides information based on the possibility of injury (consumer product
labeling based on the possibility of injury). The risk assessment principles for consumer
product labels based on the possibility of injury are referred to GB/T 36499.
5.1.6.4 Tactile warnings
If tactile warnings are used, the technical specifications shall comply with GB/T 35929.
6 Hazard communication. Material safety data sheet (SDS)
6.1 General provisions
6.1.1 Material Safety Data Sheet shall be prepared for substances and mixtures, that
meet the physical, health or environmental hazard classification criteria in 4.1.1, and all
mixtures whose ingredients meet the carcinogenicity, reproductive toxicity or target
organ toxicity criteria and whose concentrations exceed the critical value/concentration
limit specified in the mixture standard in Table 1.For mixtures that do not meet the
hazard classification criteria but contain hazardous ingredients at a certain
concentration, the competent authority may also require the provision of a material
safety data sheet.
