HS Code Chapter 27 covers one of the most commercially important categories in international trade: mineral fuels, mineral oils, petroleum products, coal, petroleum gases, bituminous substances, mineral waxes and electrical energy.

Businesses involved in oil and gas, petrochemicals, industrial manufacturing, power generation, transportation, construction and energy trading regularly encounter products that may fall within Chapter 27 of the Harmonized System.

Identifying the chapter, however, is only the first stage of customs classification. Products described commercially as oil, fuel, gas, lubricant or petroleum product do not automatically receive the same HS code.

The correct classification can depend on factors such as chemical composition, petroleum content, processing method, physical state, distillation characteristics, additives and whether another HS heading describes the product more specifically.

What Products Fall Under HS Chapter 27?

The official scope of Chapter 27 covers mineral fuels, mineral oils and products of their distillation, bituminous substances and mineral waxes.

In practical trade terms, the chapter brings together several major commodity groups.

This list is useful for understanding the general scope of the chapter, but it should not be used as a shortcut for determining the final HS code of a particular product.

For example, two materials both sold as “industrial oil” can be classified differently if one is primarily a petroleum oil and the other is a formulated chemical preparation with additives that bring it within another heading.

Understanding the 2-, 4- and 6-Digit HS Structure

The Harmonized System is hierarchical. Classification begins with a broad chapter and becomes progressively more specific through headings and subheadings.

Under the international Harmonized System, headings are identified by four digits, while six-digit codes identify the international subheading level.

This distinction is important for trade involving Saudi Arabia, the United Arab Emirates (UAE), Qatar, Oman, Kuwait and Bahrain because the international six-digit classification can be extended by the applicable destination tariff for customs declaration purposes.

HS Chapter 27 Headings: 2701–2716

HS Code Chapter 27 is divided into headings covering different mineral fuels, petroleum products, gases and related materials. Understanding these four-digit headings is essential before moving to the six-digit subheading level.

HS 2710 — Petroleum Oils and Preparations

Heading 2710 is one of the most important and technically demanding headings within Chapter 27.

It covers petroleum oils and oils obtained from bituminous minerals, other than crude oils, together with certain preparations not elsewhere specified or included where qualifying petroleum oils make up at least 70% by weight and are the basic constituents of the preparation.

Chapter Note 2 also explains that the references in heading 2710 to petroleum oils and oils obtained from bituminous minerals can include similar oils and oils consisting mainly of mixed unsaturated hydrocarbons obtained by any process, provided that the weight of the non-aromatic constituents exceeds that of the aromatic constituents.

Heading 2710 also contains specific provisions for products containing biodiesel and for waste oils. For Chapter 27 purposes, waste oils include qualifying used oils no longer fit for use as primary products, certain sludge oils from petroleum-oil storage tanks, and qualifying oil emulsions or mixtures with water such as those arising from spills, tank washing or cutting-oil operations.

Why Petroleum Percentage Matters

The 70% threshold is an important part of the legal wording for certain preparations, but classification should never be performed using percentage alone.

The full nature of the finished product must still be reviewed. A formulated preparation may potentially be described by another heading even though petroleum-derived materials are present.

Light Oils and Preparations

The international subheading notes provide a technical definition for light oils and preparations under subheading 2710.12.

The definition uses a distillation criterion: 90% or more by volume, including losses, must distil at 210°C according to the specified ISO method, which is equivalent to ASTM D 86.

This demonstrates why technical data can directly determine customs classification. An invoice that merely describes the goods as “petroleum oil” or “industrial oil” may not provide enough information.

HS 2711 — Petroleum Gases and Other Gaseous Hydrocarbons

Heading 2711 covers petroleum gases and other gaseous hydrocarbons. Classification at the international subheading level can depend on both the identity of the hydrocarbon and whether the product is liquefied or presented in gaseous state.

The six-digit structure includes categories for:

• Liquefied natural gas
• Liquefied propane
• Liquefied butanes
• Liquefied ethylene, propylene, butylene and butadiene
• Other liquefied petroleum gases and gaseous hydrocarbons
• Natural gas in gaseous state
• Other gaseous hydrocarbons in gaseous state

LPG Is a Commercial Description

“LPG” is a common commercial expression for liquefied petroleum gas, but it is not always sufficient to establish the exact six-digit HS code.

A shipment may consist principally of propane, butane or another qualifying mixture. The actual composition should therefore be reviewed before selecting the international subheading.

Common Commercial Products Associated with Chapter 27

Importers and exporters often begin reviewing HS Code Chapter 27 for products described commercially as:

What HS Chapter 27 Does Not Cover

Chapter 27 contains legal exclusions that can move a product into another part of the Harmonized System.

One important exclusion relates to separately chemically defined organic compounds. As a general rule, such compounds do not belong in Chapter 27, subject to the specific exceptions provided in the Chapter Notes, including pure methane and pure propane of heading 2711.

The Chapter Notes also exclude medicaments of headings 3003 and 3004, as well as mixed unsaturated hydrocarbons of headings 3301, 3302 or 3805.

These exclusions mean that a product cannot be classified simply because it is petroleum-related or hydrocarbon-based.

Chapter 27 vs Chapter 29

Chapter 29 covers organic chemicals and is an important competing chapter when a product is a separately chemically defined organic compound.

Consider a material described commercially as a hydrocarbon solvent. Before selecting Chapter 27, the classifier may need to determine:

• Whether the product is a single chemically defined compound
• Whether it is a mixture
• The proportion of aromatic and non-aromatic constituents
• The production process
• Whether Chapter 29 contains a more specific description

Chapter 27 vs Chapter 34

Lubricating products can require careful comparison between petroleum headings and headings for prepared lubricants.

A product marketed as a “lubricant” is not automatically classified within heading 2710 simply because petroleum oil appears in the formulation.

Composition, additives and the nature of the finished preparation should be examined.

Chapter 27 vs Chapter 38

Specialty chemical preparations can also create classification questions between Chapter 27 and Chapter 38.

This can be relevant for complex industrial fluids, additive packages and preparations containing petroleum-derived constituents alongside other functional chemicals.

Chapter 27 vs Chapter 39

Chapter Note 2 specifically excludes certain liquid synthetic polyolefins from the petroleum-oil references in heading 2710.

The exclusion applies where less than 60% by volume distils at 300°C, after conversion to 1,013 millibars when a reduced-pressure distillation method is used. Such products fall within Chapter 39 rather than being brought into heading 2710 merely because they resemble petroleum oils.

This is another example of why the physical and chemical properties of the actual product can matter more than its commercial appearance.

Technical Data Needed for Chapter 27 Classification

Accurate classification of mineral oils, fuels and hydrocarbon preparations frequently requires technical information beyond the commercial invoice.

Documents That Can Support Classification

Depending on the goods, useful documentation may include:

• Commercial invoice
• Technical Data Sheet (TDS)
• Safety Data Sheet (SDS)
• Certificate of Analysis (COA)
• Product specification
• Full material composition
• Hydrocarbon composition
• Petroleum percentage
• Distillation results
• Density
• Viscosity
• Flash point
• Sulfur content
• Additive information
• Biodiesel content
• Manufacturing process
• Intended application

Not every classification requires every document. The objective is to obtain enough information to eliminate incorrect headings and compare the realistic classification alternatives.

How to Classify Products Under HS Code Chapter 27

A disciplined classification process reduces the risk of selecting a code merely because its description appears similar to the commercial name of the goods.

Common HS Chapter 27 Classification Mistakes

1. Classifying Only from the Commercial Product Name

Terms such as “fuel oil,” “industrial oil,” “hydrocarbon” and “lubricant” can cover products with materially different compositions and legal tariff characteristics.

The commercial name should therefore be treated as a starting point, not as the final classification.

2. Assuming Every Lubricant Belongs Under 2710

The presence of petroleum oil does not automatically place a finished lubricant in heading 2710.

The percentage of petroleum oil, the additives and the overall nature of the preparation should be considered together with potentially competing headings.

3. Ignoring Composition Thresholds

Chapter 27 contains several technical and percentage-based rules. Ignoring those criteria can lead to classification at the wrong heading or subheading.

4. Ignoring Physical State

Under heading 2711, the distinction between liquefied products and gases presented in gaseous state affects the international subheading.

5. Confusing Crude and Refined Petroleum Products

Crude petroleum oils are classified differently from many refined petroleum oils and preparations.

Understanding the processing history of the material is therefore important.

6. Copying the Supplier's HS Code Without Verification

A supplier's code can be a useful reference, but it is not conclusive.

The supplier may be using a tariff extension from a different jurisdiction, may have classified a different version of the product, or the original classification may itself require correction.

7. Treating Six Digits as the Final Destination Declaration Code

Six digits represent the internationally harmonized subheading level. For an actual declaration, the current destination tariff must then be checked separately for Saudi Arabia, the UAE, Qatar, Oman, Kuwait or Bahrain.

HS Chapter 27 in Saudi Arabia, UAE, Qatar, Oman, Kuwait and Bahrain

Chapter 27 is especially relevant to Gulf trade because petroleum, natural gas, energy, petrochemical and industrial supply chains are significant across Saudi Arabia, the United Arab Emirates (UAE), Qatar, Oman, Kuwait and Bahrain.

These six countries participate in the Gulf customs-union framework, which includes a common external customs tariff and a Common Customs Law. The international Harmonized System classification remains the common starting point for identifying the goods.

For customs purposes, however, determining the international six-digit HS subheading is not necessarily the final operational step. The importer or exporter should then verify the current detailed tariff, customs procedures and regulatory requirements that apply in the actual destination market.

This distinction is important for companies supplying the same product to several Gulf markets. The international HS analysis provides a common classification foundation, while destination-specific requirements are checked separately for the actual transaction.

This is also why an educational Chapter 27 article should not be treated as a substitute for classifying a specific shipment.

Explore HS Chapter 27 by Heading

Chapter 27 can be expanded into individual classification guides for each four-digit heading, with additional articles covering the corresponding six-digit international subheadings.

As each guide is published, these items can be converted into internal links. The four-digit guides can then link to their corresponding six-digit articles, creating a complete Chapter 27 content cluster.

the classification process can consider the actual description, specifications, supporting documentation, origin and destination of the goods.

Final Takeaway

HS Code Chapter 27 is the primary Harmonized System chapter for mineral fuels, petroleum oils, petroleum gases, coal, bituminous substances, mineral waxes and related commodities.

But identifying Chapter 27 is only the beginning.

A complete classification may require determining:

• The correct four-digit heading
• The correct six-digit international subheading
• The applicable detailed tariff extension
• Whether a legal Chapter Note excludes the goods
• Whether another chapter describes the product more specifically
• Whether percentage or technical thresholds apply
• Whether physical or chemical characteristics affect classification

For straightforward commodities, classification can be relatively direct. For petroleum preparations, industrial oils, specialty fuels, hydrocarbon mixtures and lubricants, the technical details can materially change the result.

Do not classify a product only because its commercial name resembles a tariff description.

Start with the actual goods, identify the relevant HS provisions and supporting technical information, and verify the current destination tariff and customs requirements in Saudi Arabia, UAE, Qatar, Oman, Kuwait or Bahrain before completing the customs declaration.
