3808 93 90: Zararlı bitkileri yok edici, sürgünleri önleyici, bitki -: bitkilerin büyümesini düzenleyiciler

See Note 1 (a) (2) to Chapter 38 and the HS Explanatory Note to heading 3808, fourth paragraph, (1), regarding the term ‘put up in packings for retail sale’.

For the purposes of this heading, separate chemically defined elements or compounds can be regarded as ‘products put up in packings for retail sale’, provided that they are put up in packings ready for retail sale directly to end users (private persons, professionals, companies, etc.) without further processing or repacking. These packings must bear legible, visible and indelible instructions for the intended use by the end user (for example, safety, use or handling instructions). Providing this information on accompanying documents only is not sufficient.

Preparations are included under this heading even if they are not put up for retail sale.

This subheading covers substances which, when applied to plants, alter their physiological processes in a desired direction. They are applied to the whole plant, to parts of the plant or to the soil.

Their action can influence, for example:

(a) overall growth;

(b) plant height (stem lengthening or shortening);

(c) size or form of tubers;

(d) internodal length (improvement of resistance to loding);

(e) fruiting and size of fruit;

(f) level of plant reserves (carbohydrates, proteins, fats);

(g) time of flowering or fruit-ripening;

(h) plant sterility;

(ij) number of female flowers.

Plant-growth regulators fall into four major categories:

1. auxins which act on root formation, stalk growth and fruit development. The most important is indol-3-ylacetic acid;

2. gibberellins which promote, in particular, bud growth and blossoming. They are all derived from gibberellic acid;

3. cytokinins which promote, in particular, cell division and retard ageing of the plant. The best-known are kinetin (6-furfurylaminopurine) and zeatin;

4. growth retarders.

This subheading does not include:

(a) fertilisers;

(b) soil improvers (conditioners);

(c) herbicides, whether or not selective (subheadings 3808 93 11 to 3808 93 27);

(d) anti-sprouting products (subheading 3808 93 30).
