2901 24 00: Butadiene and isoprene: Acyclic hydrocarbons, unsaturated, buta-1,3-diene and isoprene

General

The letters ‘(INN)’, after a name appearing in the Combined Nomenclature and the explanatory notes thereto, indicate that the name is included in the list of International Nonproprietary Names for Pharmaceutical Substances published by the World Health Organisation.

The letters ‘(INNM)’ indicate that the name is accepted by the World Health Organisation as an ‘International Nonproprietary Name Modified’.

The letters ‘(ISO)’ indicate that the name appears as one of the ‘common names for pest control chemicals and plant growth regulators’ in recommendation R 1750 of the International Organisation for Standardisation.

A fused system is one in which there are at least two rings which have one, and only one, common bond and have two, and only two, atoms in common.

Separate chemically defined organic compounds, presented as a food supplement in capsules (except microcapsules), for example of gelatine, are excluded from this chapter because the presentation in capsules is a treatment that is not covered by note 1 to this chapter.

Note 1(b)

See the HS General Explanatory Note to this chapter, (A), final paragraph.

Note 1(d)

The aqueous solutions permitted are only those that are true solutions, even if because of insufficient water the substance is only partly dissolved.

Note 1(f)

As regards the addition of a stabiliser, anti-dusting agent, colouring agent or odoriferous substances, see the HS General Explanatory Note to this chapter, (A), penultimate paragraph.

Note 1(g)

As regards the addition of a stabiliser, anti-dusting agent, colouring agent or odoriferous substances, see the HS General Explanatory Note to this chapter, (A), penultimate paragraph.

Note 5

The provisions of this note apply only to the classification, as between headings, of the products concerned (see the HS General Explanatory Note to this chapter, (G)).

For classification as between the subheadings within a heading, the provisions of subheading note 1 to this chapter are to be applied.
