Notes
1. This chapter does not cover:
(a). Separate chemically defined elements or compounds with the exception of the following:
(1). Artificial graphite (heading 3801);
(2). Insecticides, rodenticides, fungicides, herbicides, antisprouting products and plant-growth regulators, disinfectants and similar products put up as described in heading 3808;
(3). Products put up as charges for fire-extinquishers or put up in fire-extinguishing grenades (heading 3813);
(4). Certified reference materials specified in note 2 below;
(5). Products specified in note (3a) or (3c) below.
(b). Mixtures of chemicals with foodstuffs or other substances with nutritive value, of a kind used in the preparation of human foodstuffs (generally, heading 2106);

(d). Medicaments (heading 3003 or 3004); or
(e). Spent catalysts of a kind used for the extraction of base metals or for the manufacture of chemical compounds of base metals (heading 2620), spent catalysts of a kind used principally for the recovery of precious metal (heading 7112) or catalysts consistin g of metals or metal alloys in the form of, for example, finely divided powder or woven gauze (section XIV or XV).
2. (a). For the purposes of heading 3822, the expression certified reference materials means reference materials which are accompanied by a certificate which indicates the values of the certified properties, the methods used to determine these values and the deg ree of certainty associated with each value and which are suitable for analytical, calibrating or referencing purposes.
(b). With the exception of the products of chapter 28 or 29, for the classifications of certified reference materials, heading 3822 shall take precedence over any other heading in the Schedule B.
3. Heading 3824 includes the following goods which are not to be classified in any other heading of the export schedule:
(a). Cultured crystals (other than optical elements) weighing not less than 2.5 g each, of magnesium oxide or of the halides of the alkali or alkaline-earth metals;

4. Throughout the Schedule B, municipal waste means waste of a kind collected from households, hotels, restaurants, hospitals, shops, offices, etc., road and pavement sweepings, as well as construction and demolition waste. Municipal waste generally contai ns a large variety of materials such as plastics, rubber, wood, paper, textiles, glass, metals, food materials, broken furniture and other damaged or discarded articles. The term municipal waste, however, does not cover:

5. For the purposes of heading 3825, sewage sludge means sludge arising from urban effluent treatment plants and includes pre-treatment waste, scouring and unstabilized sludge. Stabilized sludge, when suitable for use as fertilizer, is excluded (chapter 31 ).
6. For the purposes of heading 3825, the expression other wastes applies to:
(a). Clinical waste, that is, contaminated waste arising from medical research, diagnosis, treatment or other medical, surgical, dental or veterinary procedures, which often contain pathogens and pharmaceutical substances and require special disposal procedures (for example, soiled dressings, used gloves and used syringes);
(b). Waste organic solvents;
(c). Wastes of metal pickling liquors, hydraulic fluids, brake fluids and anti-freezing fluids; and
(d). Other wastes from chemical or allied industries.
The expression “other wastes” does not, however, cover wastes which contain mainly petroleum oils or oils obtained from bituminous minerals (heading 2710).
7. For the purposes of heading 3826, the term biodiesel means mono-alkyl esters of fatty acids of a kind used as a fuel, derived from animal or vegetable fats and oils whether or not used.
