This heading covers :
(A) Products suitable for use as glues or adhesives and put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg. This group covers the prepared glues and adhesives of (B) below and other products suitable for use as glues or adhesives, provided they are put up for retail sale as glues or adhesives in packages the content of which does not exceed 1 kg. The packages in which glues or adhesives are usually put up for retail sale include glass bottles or jars, metal boxes, collapsible metal tubes, cartons, paper bags, etc.; sometimes the "packaging" is merely a paper band wrapped round, for example, a slab of bone glue. A small brush of the appropriate type is sometimes packed with glues or adhesives (e.g., those put up in jars or tins ready for direct use). Such brushes are classified with the glues or adhesives if packed therewith. Products having other uses in addition to use as glues or adhesives (e.g., dextrins, methyl cellulose in granules) are classified in this heading only if there is some indication on the packages that they are intended for sale as glues or adhesives. (B) Prepared glues and other prepared adhesives, not covered by a more specific heading in the Nomenclature, for example : (1) Gluten glues ("Vienna glues") normally obtained from gluten rendered soluble by partial fermentation. These glues are usually in the form of flakes or powders and vary in colour from yellowish to brown. (2) Glues or other adhesives obtained by chemically treating natural gums. (3) Adhesives based on silicates, etc. (4) Preparations specially formulated for use as adhesives, consisting of polymers or blends thereof of headings 39.01 to 39.13 which, apart from any permitted additions to the products of Chapter 39 (fillers, plasticisers, solvents, pigments, etc.), contain other added substances not falling in that Chapter (e.g., waxes). (5) Adhesives consisting of a mixture of rubber, organic solvents, fillers, vulcanising agents and resins. Except when they comply with the provisions of paragraph (A) above, the heading excludes products covered by a more specific heading in the Nomenclature, for example : (a) Casein glues (heading 35.01), glues of animal origin (heading 35.03) and glues based on starches, or on dextrins or other modified starches (heading 35.05). (b) Other products, which can be used as glues or other adhesives either directly or after treatment, for example, bird lime (heading 13.02), silicates, not mixed (heading 28.39), calcium caseinate (heading 35.01), dextrin (heading 35.05), dispersions or solutions of polymers of headings 39.01 to 39.13 (Chapter 39 or heading 32.08) and dispersions or solutions of rubber (Chapter 40). It is to be noted that certain of the products included in this heading are usable as glues or adhesives in the form in which they are sold, while others must be dissolved or dispersed in water before use. The heading does not cover prepared glazings and dressings for textiles, etc. (heading 38.09) or foundry core binders (heading 38.24); in certain countries, these substances are sometimes called "glues", but they are not used for their adhesive properties. The heading also excludes products having the character of mastics, fillings, etc., of heading 32.14.
