Collodions and celloidin Collodion is a solution of nitrocellulose containing 12 % by weight of nitrogen in a mixture of ether and alcohol. On drying, this solution leaves an elastic layer of nitrocellulose, the flexibility of which may be increased by adding castor oil. A collodion may also be obtained by dissolving nitrocellulose in acetone. Collodion is used to prepare photographic...

Other This subheading covers non-plasticised cellulose nitrates (nitrocellulose) other than collodions and celloidin, even if for reasons of safety they are dampened — generally, with ethyl or butyl alcohol — or rendered harmless in some other manner.

Carboxymethylcellulose and its salts Carboxymethylcellulose is obtained through the reaction of monochloroacetic acid with alkali cellulose. It is used mainly as a thickener and as a colloid protective agent.

Other This subheading includes cellulose, not specified or included elsewhere, in primary forms. Because of its usual commercial form, regenerated cellulose is not generally classified here. In the form of fine and transparent film, it falls in heading 3920 or 3921 and, in the form of textile fibres, in Chapter 54 or 55. This subheading includes blends of cellulose esters and cellulose...

Chapter 39 Notes (11)

1. 1. Throughout the Nomenclature the expression "plastics" means those materials of headings 39.01 to 39.14 which are or have been capable, either at the moment of polymerisation or at some subsequent stage, of being formed under external influence (usually heat and pressure, if necessary with a solvent or plasticiser) by moulding, casting, extruding, rolling or other process into shapes which are retained on the removal of the external influence. Throughout the Nomenclature any...

2. 2. This Chapter does not cover: • (a) Lubricating preparations of heading 27.10 or 34.03; • (b) Waxes of heading 27.12 or 34.04; • (c) Separate chemically defined organic compounds (Chapter 29); • (d) Heparin or its salts (heading 30.01); • (e) Solutions (other than collodions) consisting of any of the products specified in headings 39.01 to 39.13 in volatile organic solvents when the weight of the solvent exceeds 50% of the weight of the solution (heading 32.08); stamping foils of...

3. 3. Headings 39.01 to 39.11 apply only to goods of a kind produced by chemical synthesis, falling in the following categories: • (a) Liquid synthetic polyolefins of which less than 60% by volume distils at 300°C, after conversion to 1,013 millibars when a reduced-pressure distillation method is used (headings 39.01 and 39.02); • (b) Resins, not highly polymerised, of the coumarone-indene type (heading 39.11); • (c) Other synthetic polymers with an average of at least 5 monomer units; •...

4. 4. The expression "copolymers" covers all polymers in which no single monomer unit contributes 95% or more by weight to the total polymer content. For the purpose of this Chapter, except where the context otherwise requires, copolymers (including co-polycondensates, co-polyaddition products, block copolymers and graft copolymers) and polymer blends are to be classified in the heading covering polymers of that comonomer unit which predominates by weight over every other single comonomer...

5. 5. Chemically modified polymers, that is those in which only appendages to the main polymer chain have been changed by chemical reaction, are to be classified in the heading appropriate to the unmodified polymer. This provision does not apply to graft copolymers.

6. 6. In headings 39.01 to 39.14, the expression "primary forms" applies only to the following forms: • (a) Liquids and pastes, including dispersions (emulsions and suspensions) and solutions; • (b) Blocks of irregular shape, lumps, powders (including moulding powders), granules, flakes and similar bulk forms.

7. 7. Heading 39.15 does not apply to waste, parings and scrap of a single thermoplastic material, transformed into primary forms (headings 39.01 to 39.14).

8. 8. For the purpose of heading 39.17, the expression "tubes, pipes and hoses" means hollow products, whether semi-manufactures or finished products, of a kind generally used for conveying, conducting or distributing gases or liquids (for example, ribbed garden hose, perforated tubes). This expression also includes sausage casings and other lay-flat tubing. However, except for the last-mentioned, those having an internal cross-section other than round, oval, rectangular (in which the...

9. 9. For the purpose of heading 39.18, the expression "wall or ceiling coverings of plastics" applies to products in rolls, of a width not less than 45 cm, suitable for wall or ceiling decoration, consisting of plastics fixed permanently on a backing of any material other than paper, the layer of plastics (on the face side) being grained, embossed, coloured, design-printed or otherwise decorated.

10. 10. In headings 39.20 and 39.21, the expression "plates, sheets, film, foil and strip" applies only to plates, sheets, film, foil and strip (other than those of Chapter 54) and to blocks of regular geometric shape, whether or not printed or otherwise surface-worked, uncut or cut into rectangles (including squares) but not further worked (even if when so cut they become articles ready for use).

11. 11. Heading 39.25 applies only to the following articles, not being products covered by any of the earlier headings of sub-Chapter II: • (a) Reservoirs, tanks (including septic tanks), vats and similar containers, of a capacity exceeding 300 litres; • (b) Structural elements used, for example, in floors, walls or partitions, ceilings or roofs; • (c) Gutters and fittings therefor; • (d) Doors, windows and their frames and thresholds for doors; • (e) Balconies, balustrades, fencing,...
