HARMONIZED SYSTEM (HS)
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.

HARMONIZED SYSTEM (HS)
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

Example:
Due to safety reasons 2%
chloropicrin (odoriferous
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
more appropriate for a specific
uses and is classified as a

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.
This is why unmixed substances,
although they are used as references,
must be classified under Chapter 28 or 29.

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).

Polyol
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, continuation
Functionality of a polyol
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.
Polyol: Formation of a polyurethane
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
Heat
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.

products of the chemical or allied industries
Legal Note N.º 1 of Section VII
Goods 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.
Classification analysis of polyol containing ODS
(R141b), continuation
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.

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.
