Scope of Section VI
This Section covers inorganic and organic chemicals and miscellaneous chemical products
of Chapters 28 to 38.

This Section does not include products that are excluded from the Section by the virtue
of Notes to each Chapter, for example, yeast (Chapter 21), mixtures of chemicals with
foodstuffs or other substances with nutritive value, of a kind used in the preparation of
certain human foodstuffs (for example, improvers for pastry, biscuits, cakes, and other
bakers’ wares) (mainly Chapter 21), ethyl alcohol (Chapter 22), sodium chloride (Chapter
25), methane and propane (Chapter 27), optical goods (Chapter 90).

How to Classify Chemicals and Chemical Products

The GIRs provide a step-by-step basis for the classification of goods and ensure
uniform interpretation of the HS nomenclature.

As a general guide, you would need to first
understand your product before you can identify the possible HS Chapters and Headings.

Once the possible HS Chapters and Headings are identified, check and apply the relevant
Section Notes, Chapters Notes and Subheading Notes to obtain the 4-digit HS heading.

In every case, the goods must first be classified in the appropriate 4-digit HS heading,
followed by the appropriate 1-dash subheading, and the appropriate 2-dash subheading
within the selected 1-dash subheading and so on, till the 8-digit HS code is obtained.

Step1.Understand your product

To classify chemicals and chemicals products, you would need to understand the
following:

• Is it a separate chemical element, a separate chemically defined compound, or a chemical mixture?
  A separate chemically defined compound is a substance that consists of one molecular species (e.g., covalent or ionic) whose composition is defined by a constant ratio of elements and can be represented by a definitive structural diagram. In a crystal lattice, the molecular species corresponds to the repeating unit.
• What are the function, intended usage, and chemical composition of the product?
• How do the individual chemical components in the product contribute to the function and intended usage?

Step2.Identify possible Chapters and Headings

Identify the possible chapters and headings based on the chemical composition, function, and intended usage of the product.

Separate Chemical Elements and Separate Chemically Defined Compounds

Separate chemical elements and separate chemically defined compounds
(commonly known as pure chemicals) are generally classified in Chapters 28 and 29,
depending on whether they are inorganic or organic chemicals. Such chemical elements or
compounds, whether or not containing impurities, would remain classified in these
Chapters, and could still be classifiable in their respective Chapters when they are mixed
with certain substances, provided such additions do not render the product particularly
suitable for a specific use.

CHAPTER 28	CHAPTER 29
Inorganic compounds	Organic compounds
Chemical elements	Hydrocarbons
Oxides	Derivatives
Hydroxides, Inorganic acids Inorganic salts	Heterocyclic compounds Apart from carbon they may also contain N, O, S…
Generally soluble in water and insoluble in organic solvents	Generally insoluble in water and soluble in organic solvents

The presence of by-products or unconverted starting materials as a result of the
the manufacturing process of a chemical product of Chapter 28 or 29 could be regarded as
permissible impurities. The chemical product could still be classified in Chapter 28 or 29
provided that these impurities are not deliberately left in the product to render it suitable
for a specific use.
*Note: If the product is a plastic product, it is possible to be classified in Chapter 39 of Section VII.
Refer to Chapter Notes of Chapter 39 to check if the product is classifiable under that Chapter

Chemical Mixture

Chemical mixtures are generally classified in Chapters 30 to 38 based on their
intended usage. You should shortlist the possible HS headings according to the intended
usage of your product.

Step3.Apply the relevant Section Notes,
Chapter Notes and Subheading Notes

Examine and apply the Section Notes, Chapter Notes and Subheading Notes of all the
identified possible HS headings for the product, in order to identify the most appropriate HS heading.

The Notes will state the following:

• Definitions and clarifications of certain terms and products
• Classification of certain products in a specific heading that takes precedence over
  other headings of the Section or the Nomenclature
• Scope of products in specific chapters, headings and subheadings by excluding or
  including certain group(s) of products

With reference to Note 1 of Chapter 28 and 29, other than separate chemical
elements and separate chemically defined compounds (whether or not containing
impurities), your chemical product can be classifiable under Chapter 28 or 29 if:

• The product is dissolved in water;
• The product is dissolved in other solvents provided the solution constitutes a
  normal and necessary method of putting up these products solely for reasons of
  safety or for transport
• The product contains an added stabiliser (including an anti-caking agent) for
  preservation or transport
• The product contains an added anti-dusting agent or a colouring substance to
  facilitate their identification or for safety reasons, provided that the additions do
  not render the product particularly useful for specific use rather than for general
  use.

However, certain separate chemical elements and chemically defined compounds
are excluded from Chapter 28 and 29 and are classifiable in other Chapters of the
nomenclature. For example, certain separate chemically defined compounds are classified in
Chapter 31 (Fertilisers) by Note 3c to Chapter 28 and Note 2f to Chapter 29, even when
they are clearly not used as fertilizers.
*Note: If the product is radioactive, a stable isotope or compound of stable isotope or is related to
precious metals or compounds of rare-earth metals, yttrium, scandium or of mercury, please refer to
Note 1 of Section VI.

Step4.Determine the HS code at 8-digit level

Once the most appropriate HS heading for your product has been identified,
compare the HS subheadings within the HS heading to obtain the relevant HS code for your
product. Start by comparing the 1-dash descriptions to find the most suitable one. If there is
a subsequent breakdown for the 1-dash descriptions, proceed to compare and select the
most appropriate 2-dash description under that 1-dash description. Repeat the process if
there are further breakdowns under the 2-dash description until you obtain the most
appropriate 8-digit HS code for the product.

Summary Flowchart on how to classify chemicals

Case studies

Case Study 1 – Hydrogen peroxide

The Material Safety Data Sheet (MSDS) of hydrogen peroxide indicates the chemical composition as follows:

The chemical is presented in liquid form.

Step 1.Understand your product.

The MSDS is for hydrogen peroxide. However, boric acid is also present in the
composition. The function of the boric acid is to stabilize hydrogen peroxide for
preservation.

Step 2,3.Identify possible Chapters and Headings and apply the relevant Section Notes, Chapter Notes and Subheading Notes.

Based on the information of the product, it is a chemically defined compound with
an added stabiliser. Therefore, hydrogen peroxide can be classified in Chapter 28 based on
the terms of the heading and the relative section and chapter notes (Note 1 (d) to Chapter
28). The notes to Chapter 28 include the product to be classified in Chapter 28:

Step 4.Determine the HS code at 8-digit level

*Singapore customs tariff

Case Study 2 –  Camping fuel

The Material Safety Data Sheet (MSDS) of a camping fuel indicates the chemical composition as follows:

The chemical product is put up in tablet form for use as fuels for camping stoves.

Step 1.Understand your product.

The product contains 100% metaldehyde, and it is a separate chemically defined
compound. It is a type of camping fuel in tablet form.

Step 2,3.Identify possible Chapters and Headings and apply the relevant Section Notes, Chapter Notes and Subheading Notes.

It is possible for the product to be classifiable in Chapter 29 (as a separate chemically
defined compound) and in Chapter 36 as a combustible preparation. However, Note 2(ij) to
Chapter 29 excludes the product to be classified in Chapter 29 and Note 1 and 2 (a) to
Chapter 36 includes the product to be classified in Chapter 36. Therefore, the product is to
be classified in Chapter 36, HS heading 36.06.

Step 4.Determine the HS code at 8-digit level

*Singapore customs tariff

Case Study 3 –  Insecticide

The Material Safety Data Sheet (MSDS) of the insecticide indicates the chemical composition as follows:

The chemical product functions as an insecticide, to exterminate aphids in
vegetables. The product is presented in aerosol spray containers, packed for retail sale.

Step 1.Understand your product.

The chemical product is a type of insecticide with a mixture of different chemicals,
each serving different function. The chemical composition renders the product particularly
suitable for a specific use, that is, an insecticide.

Step 2.Identify possible Chapters and Headings.

As it is an insecticide, it can be classified in Section VI HS heading 38.08.

Step 3.Apply the relevant Section Notes, Chapter Notes and Subheading Notes.

The Subheading Note 1 in Chapter 38 listed out the goods covered under the HS Subheading 3808.50.

Step 4.Determine the HS code at 8-digit level

To start, compare the descriptions of 1 dash subheadings under the appropriate
heading and choose the correct 1 dash. Next, repeat the process for the subsequent lines
with 2 or more dashes.

*Singapore customs tariff

Moving on to the 4-dash subheading under the most applicable 3-dash subheading (Other),
since the product is presented in aerosol spray containers, packed for retail sale, the 4-dash
subheading description “In aerosol containers” is the most applicable description.
Moving on to the 5-dash subheading under the most applicable 4-dash subheading (In
aerosol containers), since the product contains deodorizing agents, it is most appropriate to
be classified in the 5-dash subheading (Having a deodorizing function).
Thus, the product is classified in HS Code 3808.91.91. in the case of Singapore customs tariff.

Frequently Asked Questions

Q1) I have a 10-digit HS code provided by my overseas supplier for their chemical
product. Can I use the first 8-digit for import into my country?

The HS is internationally harmonized only at the 6-digit level. You may use the HS
code provided by your overseas supplier as a reference and determine the 8-digit HS
code which is most appropriate and applicable to your product from the import country version of the HS code.

Q2) What information do I need to determine the HS code of chemical products?

To determine the HS code, you may need the following information:

• • chemical composition adding up to 100%
  • chemical structure
  • product usage
  • form (i.e. powder, liquid)

The information could be found in the product catalogue/brochure or the product’s
Material Safety Data Sheet (MSDS).

Q3) Can I determine the HS code of a chemical product using its CAS Registry Number?

Chemical Abstracts Service Registry Number (CAS RN) is a unique number tagged to
a chemical by the American Chemical Society and is used internationally to identify
chemicals. For chemicals with CAS RN.
However, since the list is not exhaustive, you may also refer to the Europa website for assistance.
Do note that the Europa website is meant as a guide and
traders are advised to make reference to the import Customs publication for the 8-digit HS code.
The next alternative is to research on the chemical structure and its functionality of
the chemical in the web, and determine the most appropriate HS code.

Q4) Is there a specific HS heading for washing preparations for cleaning industrial machines?

If the washing preparation is in the form of bar, cake, moulded piece or shape, they
would be classified in HS heading 34.01. Otherwise, it would be classified under HS
heading 34.02 if it is in other forms (e.g. liquid, pastes, etc.) not specified in HS
heading 34.01.

Chapter 28 Inorganic Chemicals

Inorganic Chemicals; Organic or Inorganic Compounds of
Precious Metals, of Rare-Earth Metals, of Radioactive Elements or of Isotopes

This Chapter covers, in principle, separate chemical elements and separate chemically
defined compounds, subject to the provision of the legal notes.
As specified in Note 2 to the Chapter, certain compounds containing carbon in their
structures are to be classified in Chapter 28 as inorganic compounds, such as oxides of
carbon, Calcium carbonate.
Separate chemical elements and separate chemically defined compounds containing
impurities, or dissolved in water, remain classified in Chapter 28.

Chapter 28 is categorized into six groups as shown below:

For purposes of transportation and preservation, Separate chemically defined elements
and compounds put up with an added stabilizer remain classified in this Chapter. Products
added to certain chemicals to keep them in their original physical state are also to be
regarded as stabilizers, provided that the addition does not alter the character of the basic
product and render it particularly suitable for specific use rather than for general use.

Example;

Stabilized by the addition of Boric acid remains classified in Heading 28.47.

Hydrogen Peroxide

• Hydrogen peroxide (28.47) stabilized by additional of boric acid remain classified
in this Chapter because is of a type normally used for the purpose.
• Carbonyl Chloride dissolved in Toluene or Benzene is classified in heading
38.24.
• Carbonyl chloride (subheading 2812.11) dissolved in benzene cannot remain
classified in this chapter because the dilution is not necessary for transportation
and render the product suitable for specific usage.

The scope of priority heading 28.52, compounds of mercury, is expanded to include
the same whether or not chemically defined. 2852.10 (chemically defined inorganic or
organic compound of mercury). Non-chemically compound of mercury fall under sub
heading 2852.90.
This subdivision was done for purposes of capturing data on certain hazardous chemicals
and pesticides as measures to facilitate the monitoring and control in international trade.

Relationship with other parts of the Nomenclature
Subject to the provision of the legal notes 3 and 8 to Chapter 28, the following chemically
defined inorganic compounds are excluded from Chapter 28 and classified in other
Chapters, for example, Sodium chloride in Chapter 25, Ammonium nitrate in Chapter 31,
Precious stones in Chapter 71, Artificial graphite in Heading 38.01

	29.42	Other organic compounds

Within any one heading of this Chapter, derivatives of a chemical compound (or group
of chemical compounds) are to be classified in the same subheading as that compound
(or group of compounds) provided that they are not more specifically covered by any
other subheading and that there is no residual subheading named “Other” in the series of
subheadings concerned (subheading note 1 to Chapter 29).
The Chapter is divided into 13 categories as shown below:

Relationship with other Chapters
This Chapter does not cover :
(a) Goods of heading 15.04 or crude glycerol of heading 15.20;
(b) Ethyl alcohol (heading 22.07 or 22.08);
(c) Methane or propane (heading 27.11);
(d) The compounds of carbon mentioned in Note 2 to Chapter 28;
(e) Urea (heading 31.02 or 31.05);
Items classified in this Chapter are mainly chemically defined organic compounds other
than those excluded in note 2 to Chapter 29, some as listed above.
Impurities and stabilizers present in chemicals of this Chapter have limitation as provided
in note 1 to Chapter 29 just as it is in Chapter 28. Presence of water in most cases however
has no effect (Note 1(d) to this Chapter).
There is also a danger of misclassifying other chemicals of this Chapter such as vitamins and
antibiotic since their classification can also be affected by level of purity as demonstrated
in Chapter 27, by presentation either in bulk or put up for retail or in measured doses, or
by being mixed with other materials of other Chapters for specific use.

Relationship with other parts of the Nomenclature
• Diary feed supplements containing antibiotic and vitamins for the wellbeing of
animals – 23.09
• Vitamins and mineral supplements preparation, edible, for people’s wellbeing
or maintaining health but which can not cure or prevent diseases – 21.06
• Vitamins put up in measured doses for therapeutic or prophylactic use – 30.04

The above diagram shows classification of goods in heading 27.11 and heading 29.01 as
per the EN to heading 27.11 and EN to Heading 29.01.
For example, ethene with a level of purity less than 95% pure is classified in heading 27.11
not in heading 29.01.
heading 29.40 covers sugars chemically pure, others than sucrose, lactose, maltose,
glucose and fructose (Chapter 17). Sugar or Sucrose is classified in Chapter 17.

Preparation of Vitamins
Vitamins (Heading 29.36) are active agents, usually of complex chemical composition,
which are obtained from outside sources and are essential for the proper functioning of
human or other animal organisms (Explanatory Notes to heading 29.36).
Preparations based on vitamins are excluded from Chapter 29 and are classified in Chapters
21, 23, 30. Supplement feeds (used in animal feeding), containing antibiotics and vitamin
A, with dairy products are classified in Subheading 2309.90 (Preparations of a kind used
in animal feeding).

Vitamin and mineral supplements are classified in Chapter 21 (Miscellaneous edible
preparations), subheading 2106.90 (Other).
Multi vitamin preparations presented in soft gelatin capsules (main ingredients : ginseng
extract, vitamins, nicotinamide, calcium pantothenate) are also classified in subheading
2106.90.

this Chapter.
Tablets, capsules and syrups which do cure or treat a particular ailment or disease are
not regarded medicaments. For example, aloe vera tablets put up for retail sale in plastic
containers, of which the tablets consist of 3% aloe vera powder used as a nutritional
supplement such product is considered a food supplement classified in heading 21.06.
Note 1(b) to Chapter 30 gives clarification on the classification of preparations such as
tablets having the nature of food supplements, chewing gum or patches intended to assist
smokers to stop smoking (heading 21.06 or 38.24).
While Note 1 excluded items from this chapter, it is also important to crosscheck with
Note 4 to Chapter 30 before considering classifying item in heading 30.06.

characterized by the fact that they contain the oxygen necessary for combustion and that
in combustion they produce a large volume of gas at a high temperature, articles prepared
from explosives, pyrophoric, inflammable or combustible products for producing light,
sound, smoke, flame or sparks.

Relationship with other Chapters
This Chapter does not cover separate chemically defined compounds other than those
described in Note 2(a) or (b) to Chapter 36.

Chapter 37: Photographic or cinematographic goods

Photographic or cinematographic goods

This Chapter covers photographic plates, film, paper, paperboard and textiles of Chapter
37 are those with one or more layers of any emulsion sensitive to light or other forms of
radiation. In this Chapter the word “photographic” relates to the process by which visible
images are formed, directly or indirectly, by the action of light or other forms of radiation
on photosensitive surfaces.

Relationship with other Chapters
This Chapter does not cover waste or scrap of Chapter 38.

Chapter 38: Miscellaneous chemical products

Miscellaneous chemical products

This Chapter covers miscellaneous chemical products not covered somewhere else in
the Nomenclature. It is sometimes known as basket Chapter for chemicals not covered
somewhere else in the Nomenclature. It also covers separate chemical defined compounds
put up in packages for retail sale not covered elsewhere in other Chapters of the nomenclature.
For example sulphur-treated bands, wicks and candles, and fly paper insect-side of 38.08
which otherwise are classified as sulphur chemicals of Chapter 28.
The Chapter also covers wastes as provided by Notes 4, 5, and 6 to the Chapter 38 for
municipal waste, sewage sludge, and other waste respectively. However, wastes containing
mainly petroleum oil remain classified in Chapter 27 as per note 6 to Chapter 38.
Biodiesel is also classified in this Chapter if it contains less than 70% of petroleum oils
(38.26. Biodiesel is defined in note 7 to Chapter 38.
Classification of pesticides is based on Note 2 to Section VI which reads;

Subject to Note 1 above, goods classified in heading 30.04, 30.05, 30.06, 32.12, 33.03,
33.04, 33.05, 33.06, 33.07, 35.06, 37.07 or 38.08 by reason of being put up in measured
doses or for retail sale are to be classified in those headings and in no other heading of
the Nomenclature.
38.08 – Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and
plant-growth regulators, disinfectants and similar products, put up in forms or packings
for retail sale or as preparations or articles (for example, sulphur-treated bands, wicks and
candles, and fly papers).
The nature of packaging determines classification. When Separate chemically defined
compounds for example DDT are presented in form or packaging for retail sale, they are
classified in heading 38.08, subheading 3808.91 However, when they are presented in
bulk, they are classified in Chapter 29, subheading 2903.92.
Relationship with other Chapters
This Chapter does not cover;
(a) Separate chemically defined elements or compounds with the exception of the following;

(1) Artificial graphite (heading 38.01);
(2) Insecticides, rodentcides, fungicides, herbicides, anti-sprouting products and
plant-growth regulators, disinfectants and similar products, put up as described
in heading 38.08;
(3) Products put up as charges for fire-extinguishers or put up in fire-extinguishing
grenades (heading 38.13);
(4) Certified reference materials specified in Note 2 to Chapter 38;
(5) Products specified in Note 3 (a) or 3 (c) to Chapter 38.

(b) Mixtures of chemicals with foodstuffs or other substances with nutritive value, of a
kind used in the preparation of human foodstuffs (generally heading 21.06);

(c ) Ash and residues ( including sludges, other than sewage sludge), containing metals,
arsenic or their mixtures and meeting the requirements of Note 3(a) or 3(b) to Chapter
26 (heading 26.20);

(d) Medicaments (heading 30.03 or 30.04); or

(e) Spent catalysts of a kind used for the extraction of base metals or for the manufacture
of chemical compounds of base metals (heading 26.20), spent catalysts of a kind used
principally for the recovery of precious metal (heading 71.12) or catalysts consisting
of metals or metal alloys in the form of, for example, finely divided powder or woven
gauze (Section XIV or XV).

Special features
Note 3 to chapter 38 read that heading 38.24 includes the following goods which are
not to be classified in any other heading of the Nomenclature :

(a) Cultured crystals (other than optical elements) weighing not less than 2.5g
each, of magnesium oxide or of the halides of the alkali or alkaline-earth
metals;

(b) Fusel oil; Dippel’s oil;

(c) Ink removers put up in packings for retail sale;

(d) Stencil correctors, other correcting fluids, and correction tapes (other than
those of heading 96.12), put up in packing for retail sale; and

(e) Ceramic firing testers, fusible (for example, Seger cones).

Note 7 to Chapter 38 reads, for the purpose of heading 38.26, the term ‘biodiesel’ means
mono-alkyls esters of fatty acids of a kind used as a fuel, derived from animal or vegetable
fats and oils whether or not used.

It is difficult to determine HS Code for Organic Chemicals only by searching tariff documents and Explanatory notes.

I suggest searching to match the structural formula from the below table images along with MSDS and CAS.
each Heading has a link to structural formula categorized by Heading by Japanese Customs.
