1 .         Purpose of Schedule

                The Tables in this Schedule replace some of the tables in the GHS.

        Note for this clause:

                See the definition of GHS in regulation 5.

Table 6.1 Classification of mixtures containing respiratory or skin sensitisers

Cut‑off values/concentration limits of ingredients of a mixture classified as either a respiratory sensitiser or a skin sensitiser that would trigger classification of the mixture.

Item	Ingredient classification	Mixture classification
		Skin sensitiser Category 1	Respiratory sensitiser Category 1
		All physical states	Solid/liquid	Gas
1.	Skin sensitiser Category 1	≥ 1.0%
2.	Skin sensitiser Sub category 1A	≥ 0.1%
3.	Skin sensitiser Sub‑category 1B	≥ 1.0%
4.	Respiratory sensitiser Category 1		≥ 1.0%	≥ 0.2%
5.	Respiratory sensitiser Sub‑category 1A		≥ 0.1%	≥ 0.1%
6.	Respiratory sensitiser Sub‑category 1B		≥ 1.0%	≥ 0.2%

        Note for this Table:

                Table 6.1 replaces Table 3.4.5 in the GHS, p. 159.

Table 6.2 Classification of mixtures containing carcinogens

Cut‑off values/concentration limits of ingredients of a mixture classified as a carcinogen that would trigger classification of the mixture.

Item	Ingredient classification	Mixture classification
		Category 1 carcinogen	Category 2 carcinogen
1.	Category 1 carcinogen	≥ 0.1%
2.	Category 2 carcinogen		≥ 1.0%

        Notes for this Table:

        1.         The concentration limits in Table 6.2 apply to solids and liquids (w/w units) and gases (v/v units).

        2.         Table 6.2 replaces Table 3.6.1 in the GHS, p. 174.

Table 6.3 Classification of mixtures containing reproductive toxicants

Cut‑off values/concentration limits of ingredients of a mixture classified as a reproductive toxicant or for effects on or via lactation that would trigger classification of the mixture.

Item	Ingredient classification	Mixture classification
		Category 1 reproductive toxicant	Category 2 reproductive toxicant	Additional category for effects on or via lactation
1.	Category 1 reproductive toxicant	≥ 0.3%
2.	Category 2 reproductive toxicant		≥ 3.0%
3.	Additional category for effects on or via lactation			≥ 0.3%

        Notes for this Table:

        1.         The concentration limits in Table 6.3 apply to solids and liquids (w/w units) and gases (v/v units).

        2.         Table 6.3 replaces Table 3.7.1 in the GHS, p. 187.

Table 6.4 Classification of mixtures containing specific target organ toxicants (single exposure)

Cut‑off values/concentration limits of ingredients of a mixture classified as a specific target organ toxicant that would trigger classification of the mixture.

Item	Ingredient classification	Mixture classification
		Category 1	Category 2
1.	Category 1 specific target organ toxicant	Concentration ≥ 10%	1.0% ≤ concentration < 10%
2.	Category 2 specific target organ toxicant		Concentration ≥ 10%

        Notes for this Table:

        1.         The concentration limits in Table 6.4 apply to solids and liquids (w/w units) and gases (v/v units).

        2.         Table 6.4 replaces Table 3.8.2 in the GHS, p. 197.

Table 6.5 Classification of mixtures containing specific target organ toxicants (repeated exposure)

Cut‑off values/concentration limits of ingredients of a mixture classified as a specific target organ toxicant that would trigger classification of the mixture.

Item	Ingredient classification	Mixture classification
		Category 1	Category 2
1.	Category 1 specific target organ toxicant	Concentration ≥ 10%	1.0% ≤ concentration < 10%
2.	Category 2 specific target organ toxicant		Concentration ≥ 10%

        Notes for this Table:

        1.         The concentration limits in Table 6.5 apply to solids and liquids (w/w units) and gases (v/v units).

        2.         Table 6.5 replaces Table 3.9.3 in the GHS, p. 207.
