This heading includes:

(1) Amino-aldehyde resins. These are resins formed by condensation of amines or amides with aldehydes (formaldehyde, furfurol, etc.). The most important are urea resins (e.g., urea-formaldehyde resin, or urea-formaldehyde resin), thiocarbamide resins (e.g., thiourea-formaldehyde resin, or thiocarbamido-formaldehyde resin), melamino-aldehyde resins (e.g., melamino-formaldehyde resin), and aniline resins (e.g., aniline-formaldehyde sin). These resins are used for the manufacture of transparent, translucent or brightly colored plastic products and are mainly used for the manufacture of dishes and haberdashery and electrical goods. In solutions and dispersions (emulsion x and suspensions), (modified or unmodified by oils, fatty acids, alcohols or synthetic polymers), amino-aldehyde resins are used as adhesives, for appreting tissues, etc. (see general clauses for this group, exception (b) for the classification of glues). Polymethylene phenylisocyanate (often referred to as "raw MDI", "polymer MDI" or "polydiphenylmethanediisocyanate") is a liquid ranging from opaque dark brown to transparent light brown, and which is obtained by reacting aniline and formaldehyde to form a mixture of methylene phenylamine oligomers, which then reacts with phosgene and, when heated, forms isocyanate functional groups. The product is a chemically modified polymer of aniline and formaldehyde (chemically modified aminosmol). It contains the actual MDI and mixtures of MDI oligomers. For chemical structures see below:

Monomers MDI Oligomers MDI (n = 1-6)

Polyamine resins such as polyethyleneamines do not belong to amino-aldehyde resins and are classified in heading 3911 as required by Note 3 to this Chapter. (2) Phenol-aldehyde resins. This category of resins includes a large group of resins obtained by condensation of phenol or its homologues (cresol, xylenol, etc.) or substituted phenols with aldehydes such as formaldehyde, acetaldehyde, furfurol, etc. The nature of the products obtained depends largely on the conditions under which the reaction is carried out, and on whether it is modified by the introduction of other substances. Thus, it includes:

(a) Resins (novolaki), which are capable of repeatedly melting and dissolving in alcohol or other organic solvents and which are obtained in an acidic medium. Novolaks are used to prepare varnishes and press powders, etc. (b) Thermosetting phenols are aldehyde resins that form in an alkaline medium. At the same time, various products are obtained at different stages of the reaction. First, resols are obtained in the form of liquids, pastes or solids, which are used as a basis for varnishes, impregnating compounds, etc. Resitols are then formed which are used as press powders and, at the end of the reaction, resites are obtained which form part of the finished materials, for example, plates, sheets, rods, pipes or other articles, usually included in headings 3916 to 3926. Certain resins of this type are ion exchange resins and are classified in heading 3914. (c) Oil-soluble phenol-aldehyde resins (soluble in drying mas-lachs) obtained from butylphenol, amylphenol a, parahydroxydiphenyl or other substituted phenols. They are used mainly in the production of varnishes. (d) Products based on resins referred to in points (a), (b) and (c) above modified by the introduction of canifoli or other natural and synthetic resins (especially alkyd resins), vegetable oils, alcohols, organic acids or other components that affect their solubility in drying m aslas. These products are used in the manufacture of varnishes and paints, as surface coatings or compositions for impregnation. (3) Polyurethanes. This category of polyurethanes includes all polymers obtained from the interaction of polyfunctional isocyanates with polyhydroxy compounds, such as castor oil, butane -1,4-diol, polyols of simple and complex polyesters. Polyurethanes exist in various forms, of which the most important are foams, elastomers and coatings. They are also used as adhesives, molding compounds and fibers. These products are often marketed as one part of a multi-component system or kit. This category also includes mixtures of polyurethane and unreacted polyfunctional diisocyanate (e.g., toluenediisocyanate). For the classification of polymers (including copolymers), chemically modified polymers and polymer mixtures, see the general provisions of this chapter.

1. Within any one heading of this chapter, polymers (including copolymers) and chemically modified polymers are to be classified according to the following provisions:

(a) where there is a subheading named ‘Other’ in the same series:

(1) the designation in a subheading of a polymer by the prefix ‘poly’ (for example, polyethylene and polyamide-6,6) means that the constituent monomer unit or monomer units of the named polymer taken together must contribute 95 % or more by weight of the total polymer content;

(2) the copolymers named in subheadings 3901 30, 3901 40, 3903 20, 3903 30 and 3904 30 are to be classified in those subheadings, provided that the comonomer units of the named copolymers contribute 95 % or more by weight of the total polymer content;

(3) chemically modified polymers are to be classified in the subheading named ‘Other’, provided that the chemically modified polymers are not more specifically covered by another subheading;

(4) polymers not meeting (1), (2) or (3) above, are to be classified in the subheading, among the remaining subheadings in the series, covering polymers of that monomer unit which predominates by weight over every other single comonomer unit. For this purpose, constituent monomer units of polymers falling in the same subheading shall be taken together. Only the constituent comonomer units of the polymers in the series of subheadings under consideration are to be compared;

(b) where there is no subheading named ‘Other’ in the same series:

(1) polymers are to be classified in the subheading covering polymers of that monomer unit which predominates by weight over every other single comonomer unit. For this purpose, constituent monomer units of polymers falling in the same subheading shall be taken together. Only the constituent comonomer units of the polymers in the series under consideration are to be compared;

(2) chemically modified polymers are to be classified in the subheading appropriate to the unmodified polymer. Polymer blends are to be classified in the same subheading as polymers of the same monomer units in the same proportions.

2. For the purposes of subheading 3920 43, the term ‘plasticisers’ includes secondary plasticisers.
