The Harmonized Commodity Description and Coding System, generally referred to as "Harmonized System" or simply "HS“.

Is a multipurpose international product nomenclature developed under the auspices of the World Customs Organization (WCO), an independent intergovernmental body. The tariff schedule containing the headings, subheadings and the corresponding number codes, the notes to the Sections, of the Chapters and the Subheadings, as well as the General Rules for the interpretation of the HS.

Heading

Subheading

All countries must

classify the same

substance under

the same Subheading


The Harmonized System is based on a fundamental principle that goods are classified by what they are. In some cases, end-use is considered when a product is specifically constructed for it.

General Rule Nº1 for the interpretation of the Harmonized System:

The titles of Sections, Chapters and sub-Chapters are provided for ease of reference only; for legal purposes, classification shall be determined according to the terms of the headings and any relative Section or Chapters Notes.

substance) is added to methyl

bromide. When the content is

more than 2%, it is no longer

considered an unmixed

substance. Chloropicrin acts as

fungicide, therefore, renders it

(3) A single unmixed product.

Charged fire-extinguishing grenades: containers charged with fire-extinguishing

products (whether or not mixed), and used directly without incorporation in fire

extinguishing appliances. These are glass or pottery containers which are thrown into

the heart of the fire and which break freeing their contents, or glass containers the end

of which need only be broken between the fingers to project the extinguishing product.

The reagents of this heading are on a backing or in the form of preparations, therefore they are more than a single constituent. They may consist of admixtures of two or more reagents or of single reagent dissolved in solvents other than water. Reagents of this heading may also be put up in the form of kits, consisting of several components composed of various components. The products of this heading should de clearly identifiable as being for use only as diagnostic or laboratory reagents. This must be clear from their composition, labeling, instructions for in vitro or laboratory use, etc.

Certified reference materials of this heading are reference materials intended to calibrate a device, evaluate a measurement method or attribute values to materials.

For the classification of certified reference materials, heading 3822. has priority over any other tariff schedule, except for the products of Chapters 28 ó 29.

IMPORTANT: Before classifying a mixture under this heading, you must have the certainty that is not expressed or contained elsewhere (other heading).

Example NASF S III mixture that we saw previously, contained HCFC

(R22, R123 and R124).

As we will see, mixtures containing halogenated derivatives of

methane, ethane or propane are classified in Subheading

3824.74.

But this mixture, since it is especially prepared for extinguishers,

is under heading 3813 (more specific). Therefore, It must be

classified in this heading and never under heading 3824.

Subheadings 3824.71 to 3824.79:Subheadings 3824.71 to 3824.79 includes mixtures containing halogenated derivatives of methane, ethane or propane, including the mixtures of these halogenated derivatives with other substances.

The trade of mixtures containing halogenated derivatives of methane, ethane or propane mixtures, is controlled by the Montreal Protocol regarding ozone depleting substances.

We must distinguish “containing” from “based on”. Under this subhedings, is enough if the blend contains an halogenated derivative of methane, ethane or propane, including the mixtures

of these halogenated derivatives with other substances.

Does not need to be based on (Principal component).

Viscous liquids whose main chemical characteristic are hydroxyl (OH) groups

composed of oxygen and hydrogen. These Groups react with the isocyanate

groups (N=C=O) of the isocyanate giving place to urethane groups. It is worth

distinguishing between polyetherpolyol and polyesterpolyol.

POLYETHERPOLYOL: obtained from a reaction of polyhydroxylated alcohols

(i.e., glycols, glycerin, raw sugar) or amine (i.e., ethylendiamine) with alkylene

oxide. Polyols used for manufacturing rigid foam are mostly obtained from

propylene oxide.

POLYESTERPOLYOL: obtained from the reaction of polyvalent carboxylic

acids (i.e., phthalic acid, terephthalic acid or adipic acid) with similar glycols,

glycerin or polyalcohols. Water and polyol with ester structure are obtained.

Polyol

Polyol, continuation

Indicates the number of hydroxyl groups existing in the molecule. If the

polyol is a mixture of components of different functionalities, then the mean

functionality is indicated.

The parts of a molecule that are capable of reacting,

i.e., hydroxyl groups, are called functional groups. The content in hydroxyl

groups in a compound is called hydroxyl index or OH index.

Functionality of a polyol

Polyol: Formation of a polyurethane

Heat

The manufacture of rigid PUR foam requires two main components that are liquid, a polyol and a isocyanate as well as an blowing agent. Generally speaking, an blowing agent and other auxiliaries, such as activators (reaction accelerators), foam stabilizers, flame retardants, etc. are mixed with the polyol. The polyaddition reaction that takes place when the polyol and the isocyanate are mixed leads to the formation of urethane structure macromolecules

Also the water present reacts with the isocynate to form a polyurea and carbon dioxide, which acts as an expansion agent, being able to be the only one present.

Section VII (chapters 39 and 38)products of the chemical or allied industries

Legal Note N.º 1 of Section VIIGoods put up in sets consisting of two or more separate constituents, some or all of which fall in this section and are intended to be mixed together to obtain a product of section VI or VII, are to be classified in the heading appropriate to that product, provided that the constituents are:

a) Having regard to the manner in which they are put up, clearly identifiable as being intended to be used together without first being repacked;

(b) Entered together (presented simultaneously); and

(c) Identifiable, whether by their nature or by the relative proportions in which they are present, as being complementary one to another.

Classification analysis of polyol containing ODS (R141b), continuation

Systems: POLYOL + ISOCYANATE

Systems are usually formed by two components:

On the one hand, polyol (A) and on the other, isocyanate (B). These

components are mixed in a determinate proportion, and therefore, in systems,

are presented in this proportion. Summarizing, if the final mixture, has 1 part of

component A and 1.4 parts of component B, for each ton of component A there

will be 1.4 tons of component B.

Therefore, a system, satisfies the requirements of Legal Note Nº 3 of Section

VI:

a) Clearly identifiable by their packaging, as intended to be used

together without prior reconditioning;

b) Presented simultaneously; and

c) Complementary one to another.


As set out in the note, the systems are classified in the heading appropriate for the product formed in the reaction. As the system will react forming a polyurethane, it should be classified as such.

POLYETHERPOLYOL POLYESTHERPOLYOL

THE OTHER POLYOLS


Note sobre Prepolymers:

Urethane prepolymers are those mixtures in where a portion of polyol reacts with an excess of isocyanate. Forming in this manner a liquid prepolymer. This prepolymer is in itself, a diisocyanate, but unlike the original (MDI), it has a high molecular weight, which depends on the used polyol, and a higher viscosity. This prepolymer is allowed to react with another polyol, which may or may not contain foaming agent to finally form a polyurethane. These prepolymers, do not contain a foaming agent.
