1 HSNO classification means a classification under the classification system described in [the Hazardous Substances (Classification) Notice 2017].
2 GHS classification means the United Nations Globally Harmonized System of Classification and Labelling of Chemicals, fifth revised edition. In this schedule, a reference to a GHS classification is for information only.
3 Hazardous substances that fall within HSNO classification acutely toxic 6.1C via the oral route (H301) must fall under hazard category H2 acutely toxic in those cases where neither acute inhalation toxicity classification nor acute dermal toxicity classification can be derived, for example, due to lack of conclusive inhalation and dermal toxicity data.
4 The hazard category explosives includes explosive substances and articles.
5 If the quantity of the explosive substance contained in the article is known, that quantity must be considered for the purposes of these regulations. If the quantity of the explosive substance contained in the article is not known, then, for the purposes of these regulations, the whole article must be treated as explosive.
6 The threshold quantity of fireworks, within the meaning of regulation 3 of the Hazardous Substances (Fireworks) Regulations 2001, is calculated using the [net weight of pyrotechnic substances, within the meaning of regulation 3 of the Hazardous Substances (Fireworks) Regulations 2001, but excluding the weight of any construction, packaging, or other inert material used in the fireworks].
7 If explosives of Division 1.4 are unpacked or repacked, they must be assigned to the hazard category P1a, unless the hazard is shown to still correspond to Division 1.4, in accordance with the [Hazardous Substances (Classification) Notice 2017].
8 Flammable aerosols are classified in accordance with HSNO classification 2.1.2A and are assigned to this category if they contain flammable gas 2.1.1A or 2.1.1B or flammable liquids 3.1A.
9 In order to use this hazard category, it must be documented that the aerosol dispenser does not contain flammable gas 2.1.1A or 2.1.1B or flammable liquids 3.1A.

(a)
between 15.75% (15.75% nitrogen content by weight as a result of ammonium nitrate corresponds to 45% ammonium nitrate) and 24.5% (24.5% nitrogen content by weight as a result of ammonium nitrate corresponds to 70% ammonium nitrate) by weight, and either with not more than 0.4% total combustible/organic materials or that fulfil the requirements of Annex III-2 to Regulation (EC) No 2003/2003 of the European Parliament and of the Council of 13 October 2003 relating to fertilisers (OJL 304, 21.11.2003, p 1); or

(a)
more than 24.5% by weight, except for mixtures of straight ammonium nitrate-based fertilisers with dolomite, limestone, and/or calcium carbonate with a purity of at least 90%; or
(b)
more than 15.75% by weight for mixtures of ammonium nitrate and ammonium sulphate; or
(c)
more than 28% (28% nitrogen content by weight as a result of ammonium nitrate corresponds to 80% ammonium nitrate) by weight for mixtures of straight ammonium nitrate-based fertilisers with dolomite, limestone, and/or calcium carbonate with a purity of at least 90%.
4Ammonium nitrate (350/2 500): technical grade

1 HSNO classification means a classification under the classification system described in regulation 4 of the Hazardous Substances (Classification) Regulations 2001.
2 GHS classification means the United Nations Globally Harmonized System of Classification and Labelling of Chemicals, fifth revised edition. In this schedule, a reference to a GHS classification is for information only.
3 Hazardous substances that fall within HSNO classification acutely toxic 6.1C via the oral route (H301) must fall under hazard category H2 acutely toxic in those cases where neither acute inhalation toxicity classification nor acute dermal toxicity classification can be derived, for example, due to lack of conclusive inhalation and dermal toxicity data.
4 The hazard category explosives includes explosive substances and articles.
5 If the quantity of the explosive substance contained in the article is known, that quantity must be considered for the purposes of these regulations. If the quantity of the explosive substance contained in the article is not known, then, for the purposes of these regulations, the whole article must be treated as explosive.
6 The threshold quantity of fireworks, within the meaning of regulation 3 of the Hazardous Substances (Fireworks) Regulations 2001, is calculated using the [net weight of pyrotechnic substances, within the meaning of regulation 3 of the Hazardous Substances (Fireworks) Regulations 2001, but excluding the weight of any construction, packaging, or other inert material used in the fireworks].
7 If explosives of Division 1.4 are unpacked or repacked, they must be assigned to the hazard category P1a, unless the hazard is shown to still correspond to Division 1.4, in accordance with the Hazardous Substances (Classification) Regulations 2001.
8 Flammable aerosols are classified in accordance with HSNO classification 2.1.2A and are assigned to this category if they contain flammable gas 2.1.1A or 2.1.1B or flammable liquids 3.1A.
9 In order to use this hazard category, it must be documented that the aerosol dispenser does not contain flammable gas 2.1.1A or 2.1.1B or flammable liquids 3.1A.

2Ammonium nitrate (5 000/10 000): fertilisers capable of self-sustaining decomposition
This footnote applies to ammonium nitrate-based compound/composite fertilisers (compound/composite fertilisers containing ammonium nitrate with phosphate and/or potash) that are capable of self-sustaining decomposition according to the trough test (see the UN Manual of Tests and Criteria, Part III, subsection 38.2), and in which the nitrogen content as a result of ammonium nitrate is—
(a)
between 15.75% (15.75% nitrogen content by weight as a result of ammonium nitrate corresponds to 45% ammonium nitrate) and 24.5% (24.5% nitrogen content by weight as a result of ammonium nitrate corresponds to 70% ammonium nitrate) by weight, and either with not more than 0.4% total combustible/organic materials or that fulfil the requirements of Annex III-2 to Regulation (EC) No 2003/2003 of the European Parliament and of the Council of 13 October 2003 relating to fertilisers (OJL 304, 21.11.2003, p 1); or
(b)
15.75% by weight or less and unrestricted combustible materials.
3Ammonium nitrate (1 250/5 000): fertiliser grade
This footnote applies to straight ammonium nitrate-based fertilisers and to ammonium nitrate-based compound/composite fertilisers that fulfil the requirements of Annex III-2 to Regulation (EC) No 2003/2003 and in which the nitrogen content as a result of ammonium nitrate is—
(a)
more than 24.5% by weight, except for mixtures of straight ammonium nitrate-based fertilisers with dolomite, limestone, and/or calcium carbonate with a purity of at least 90%; or
(b)
more than 15.75% by weight for mixtures of ammonium nitrate and ammonium sulphate; or
(c)
more than 28% (28% nitrogen content by weight as a result of ammonium nitrate corresponds to 80% ammonium nitrate) by weight for mixtures of straight ammonium nitrate-based fertilisers with dolomite, limestone, and/or calcium carbonate with a purity of at least 90%.
4Ammonium nitrate (350/2 500): technical grade
This footnote applies to ammonium nitrate and mixtures of ammonium nitrate in which the nitrogen content as a result of the ammonium nitrate is—

between 24.5% and 28% by weight, and that contain not more than 0.4% combustible substances; or
(b)
more than 28% by weight, and that contain not more than 0.2% combustible substances.
It also applies to aqueous ammonium nitrate solutions in which the concentration of ammonium nitrate is more than 80% by weight.
5Ammonium nitrate (10/50): “off-specs” material and fertilisers not fulfilling the detonation test
This footnote applies to—
(a)
material rejected during the manufacturing process and to ammonium nitrate and mixtures of ammonium nitrate, straight ammonium nitrate-based fertilisers, and ammonium nitrate-based compound/composite fertilisers referred to in footnotes 3, 4, and this footnote that are being or have been returned from the final user to a manufacturer, temporary storage, or reprocessing plant for a reworking, recycling, or treatment for safe use because they no longer comply with the specifications of [footnotes 3 and 4]; or
(b)
fertilisers referred to in [paragraph (a) of footnote 2 and paragraph (a) of footnote 3 to table 2] that do not fulfil the requirements of Annex III-2 to Regulation (EC) No 2003/2003.
