1. Throughout this Schedule, the expression “plastics” means those materials of head- ings 3901 to 3914 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 pres- sure, 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 this Schedule any reference to “plastics” also includes vulcanised fibre. The expression, however, does not apply to materials regarded as textile materials of Section XI.

2. This Chapter does not cover:

(a) waxes of heading 2712 or 3404;

(b) separate chemically defined organic compounds (Chapter 29);

(c) heparin or its salts (heading 3001);

specified in headings 3901 to 3913 in volatile organic solvents when the weight of the solvent exceeds 16% of the weight of the solution (heading 3208); stamping foils of heading 3212;

(e) organic surface-active agents or preparation of heading 3402;

(v) articles of Chapter 95 (for example, toys, games, sports requisites); or

(w) articles of Chapter 96 (for example, brushes, buttons, slide fasteners, combs, mouth-pieces or stems for smoking pipes, cigarette-holders or the like, parts of vacuum flasks or the like, pens, propelling pencils).

(x) articles of chapter 94 ( for example, furniture, lamps and lighting fittings, illuminated signs, prefabricated buildings).

(y)  articles of chpater 95 ( for example, toys, games sports requisites)' or

(z) articles of  Chapter 96 (for example , brushes, buttons, slide fasteners, combs, mouth - pieces or stems for smoking pipes, cigarette holders or the like parts of vacuum flask or like, pens, propelling pencils).

3. Headings 3901 to 3911 apply only to goods of a kind produced by chemical synthe- sis, falling in the following categories:

(a) liquid synthetic polyolefins of which less than 60% by volume distils at 3000C, after conversion to 1,013 millibars when a reduced pressure distillation method is used (headings 3901 and 3902);

(b) resins, not highly polymerised, of the coumarone-indene type (heading 3911);

(c) other synthetic polymers with an average of at least 5 monomer units;

(d) silicones (heading 3910);

(e) resols (heading 3909) and other prepolymers.

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 purposes of this Chapter, except where the context otherwise requires, copoly- mers (including co-polycondensates, co-polyaddition products, block copolymers and graft copolymers) and polymer bends are to be classified in the heading covering polymers of that comonomer unit which predominates by weight over every other single comonomer unit. For the purposes of this Note, constituent comonomer units of polymers falling in the same heading shall be taken together.

If no single comonomer unit predominates, copolymers or polymer blends, as the case may be, are to be classified in the heading which occurs last in numerical order among those which equally merit consideration.

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. In headings 3901 to 3914, the expression “primary forms” applies only to the follow- ing 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. Heading 3915 does not apply to waste, parings and scrap of a single thermoplastic material, transformed into primary forms (headings 3901 to 3914).

8. For the purposes of heading 3917, 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 length does not exceed 1.5 times the width) or in the shape of a regular polygon are not to be regarded as tubes, pipes and hoses but as profile shapes.

9. For the purposes of heading 3918, 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. In headings 3920 and 3921, 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. Heading 3925 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 300l;

(b) structural elements used, for example, in floors, walls or partitions, ceilings or roofs;

(c) gutters and fittings thereof;

(d) doors, windows and their frames and thresholds for doors;

(e) balconies, balustrades, fencing, gates and similar barriers;

(f) shutters, blinds (including Venetian blinds) and similar articles and parts and fittings thereof;

(g) large scale shelving for assembly and permanent installation, for example, in shops, workshops, warehouses;

(h) ornamental architectural features, for example, flutings, cupolas, dovecotes; and

(ij) fittings and mountings intended for permanent installation in or on doors, windows, staircases, walls or other parts of buildings, for example,
knobs, handles, hooks, brackets, towel rails, switch-plates and other protective plates.

12. In headings 3920 and 3921, the expression “flexible” means an article which has a modulus of elasticity either in flexture or in tension of not over 700 kilograms per square centimeter at 230C and 50 per cent. relative humidity when tested in accordance with the method of test for stiffness of plastics (ASTM Designation D-747-63), for flexural properties of plastics (ASTM Designation D-790-63), for tensile properties of plastics (ASTM Designation D-638-64T), or for tensile properties of thin plastic sheeting (ASTM Designation D-882-64T) and “rigid” means all articles other than 'flexible' as defined above.

13. Notwithstanding anything contained in Note 12 to this Chapter, in headings 3909, 3921, 3923, 3924, 3925 and 3926 "rigid ployurethane foam" means cellular polyurethane with compressive strength of 0.418 to 28.14 kg./Cm2 and flexural strength of 1.05 to 28.14 kg./Cm2 when tested in accordance with American Standard (Designation ASTM-D-2341).

14. For the purposes of headings 3919, 3920 and 3921, the expression "film" means sheetings of thickness not exceeding 0.25 millimetres.

15. For the purposes of this Chapter, “insulated ware” shall mean any multi- walled or multi-layered article intended to provide thermal insulation.

16. In relation to the products of heading 3920 and 3921, the process of metallization or lamination or lacquering shall amount to "manufacture".
