General Rules for Interpretation of the Tariff (GRI 1 to 6)

Updated 5 October 2026 · Fact-checked

The General Rules for Interpretation (GRI) are six rules, in strict order, that decide the tariff heading of goods under the Customs Tariff. Start with the heading text and Section or Chapter Notes (Rule 1). Move to later rules only if Rule 1 fails. Then apply Rules 2 to 5, and finally Rule 6 for subheadings.

Understand General Rules for Interpretation of the Tariff

The Customs Tariff is built on the Harmonised System (HS). Goods are grouped into Sections, Chapters, headings (4-digit) and subheadings (6-digit and beyond). India adds further digits for its own tariff lines. The General Rules for Interpretation tell you how to pick the correct heading when the goods are not obviously covered by one entry.

The rules work in a fixed hierarchy. You use Rule 1 first. You go to Rule 2 only if Rule 1 does not settle the matter, and so on. You never pick a rule because it gives a lower duty. Classification is about what the law says, not about what suits the importer.

Rule 1: Classification is decided by the terms of the headings and any relevant Section or Chapter Notes. Section and Chapter titles are only for reference and have no legal force. If the heading and Notes decide it, stop there. Most goods are classified at this stage.

Rule 2(a): A heading for an article also covers that article incomplete or unfinished, if it has the essential character of the complete article. It also covers the article complete or finished but presented unassembled or disassembled (for example, a bicycle imported in parts in one consignment). It likewise covers an incomplete or unfinished article presented unassembled or disassembled, if it has the essential character of the complete article. Rule 2(b): A reference in a heading to a material or substance includes goods consisting wholly or partly of that material. If this makes goods appear classifiable under two or more headings, the classification is made under Rule 3.

Rule 3 applies when goods appear classifiable under two or more headings. Apply its parts in order. 3(a): the most specific description is preferred over a more general one. If that fails, 3(b): mixtures, composite goods and goods put up in sets for retail sale are classified by the material or component giving them their essential character. If that fails, 3(c): use the heading that comes last in numerical order among those equally eligible.

Rule 4: goods that cannot be classified under Rules 1 to 3 go to the heading for the goods most akin to them. Rule 5 applies to packing and has two limbs. 5(a): cases and containers (such as camera cases or instrument cases) that are specially shaped or fitted for a particular article, suitable for long-term use, and of a kind normally sold with the article, are classified with it when presented with it. This does not apply where the packing gives the whole its essential character. 5(b): other packing materials and packing containers presented with the goods are classified with the goods if they are of a kind normally used for packing such goods. This does not apply if the packing is clearly suitable for repeated use. Rule 6: classification at subheading level follows the same rules, comparing only subheadings at the same level, and subject to the Section and Chapter Notes. Rule 6 is the way to reach the final tariff line.

The residuary entry (usually 'Other' or 'Other articles') catches goods that fit no specific entry. Use it only after a specific entry has been ruled out. Also note that when Rule 1 works, you do not look at essential character at all.

Key rules to remember

Rule 1: Heading terms + Section/Chapter Notes decide classification; titles are for reference only; Always apply first. If the Notes exclude the goods from a chapter, they cannot go there.
Rule 2(a): Incomplete/unfinished article with essential character of complete article = classified as the complete article; complete or incomplete article presented unassembled or disassembled = classified as the assembled article; Applies to goods presented in parts, usually in one consignment. For an incomplete article, the essential character test applies in both situations.
Rule 2(b): Heading for a material includes goods consisting wholly or partly of that material; If this makes the goods classifiable under two or more headings, apply Rule 3.
Rule 3(a): Most specific description is preferred to a general description; A heading naming the goods is generally more specific than one naming a class of goods.
Rule 3(b): Mixtures, composite goods and retail sets are classified by the material or component that gives essential character; Applies only if 3(a) cannot decide. Essential character may depend on bulk, weight, value, role or function. For sets, the goods must be of at least two different headings, put up to meet a particular need, and packed for direct sale without repacking.
Rule 3(c): Heading that comes last in numerical order among equally eligible headings; Last resort within Rule 3.
Rule 4: Goods that cannot be classified under Rules 1 to 3 = heading for goods most akin; Rarely used in exams.
Rule 5: 5(a): specially shaped, durable cases normally sold with the article = classified with the article; 5(b): other packing materials and containers of a kind normally used for packing such goods = classified with the goods; 5(a) does not apply if the packing gives the whole its essential character. 5(b) applies only to packing of a kind normally used for such goods, and does not apply if the packing is clearly suitable for repeated use.
Rule 6: Subheadings are compared only at the same level, using the same rules and Notes; Select the heading first, then the subheading, then the tariff item.

How to solve General Rules for Interpretation of the Tariff questions

Use the same sequence for every classification question. Show the rule you applied and why the earlier rules did not settle the matter.

1Identify the goods precisely: material, function, form, and how they are presented (assembled, in parts, in a set, packed).
2Check the Section and Chapter Notes for inclusions and exclusions, and read the competing heading texts. Apply Rule 1.
3If Rule 1 gives one heading, conclude. State the heading and the Note or text you relied on.
4If goods are incomplete, unassembled, or a mixture, apply Rule 2 and see if one heading results.
5If two or more headings still apply, apply Rule 3 in order: 3(a) specific, then 3(b) essential character, then 3(c) last in numerical order.
6Check packing under Rule 5 and fall back on Rule 4 only if nothing else fits.
7Once the heading is fixed, apply Rule 6 to choose the subheading, and use the residuary entry only if no specific subheading fits.
8Write the conclusion in provision-facts-conclusion form.

Quickest way: Rule-ladder shortcut

When to use it: Use this under time pressure, especially for MCQ case scenarios where you must choose a heading fast.

Ask: does a heading name the goods, or does a Note include or exclude them? If yes, Rule 1 is the answer.
If the goods are in parts or half-finished, ask whether they have the essential character of the whole. If yes, Rule 2(a).
If two headings both seem to apply, pick the narrower one (3(a)). If both are equally narrow, ask which component gives the main character (3(b)). For a set, first check that it has at least two different headings, serves a particular need and is packed for sale without repacking.
If still tied, choose the later heading (3(c)).
Never use a residuary entry until you have eliminated every specific one.

Common mistakes in General Rules for Interpretation of the Tariff

Jumping to essential character without trying Rule 1.
Essential character is the best-known idea in GRI, so students apply it by default.
Fix: Always start with heading text and Notes. Use Rule 3(b) only when two or more headings remain after Rules 1 and 2.
Treating Section or Chapter titles as binding.
Titles look like a legal description of the goods.
Fix: Remember that titles are for reference only. The heading text and Notes decide classification.
Applying Rule 3(c) before 3(a) and 3(b).
Students want a quick tie-breaker.
Fix: Rule 3 operates in order. Use 3(c) only when specificity and essential character both fail.
Choosing the classification with the lower duty.
Students think in terms of tax outcome.
Fix: Duty rate is irrelevant. Decide the heading by the rules, then read the rate against it.
Using the residuary entry too early.
'Other' feels safe when the goods are unusual.
Fix: First check all specific headings and Notes. A residuary entry applies only if nothing specific covers the goods.
Comparing subheadings under different headings under Rule 6.
Students forget that the heading must be fixed first.
Fix: Settle the heading first. Then compare subheadings only at the same level within that heading.

Worked examples

Example 1

A company imports a bicycle in a single consignment, disassembled into frame, wheels, handlebar, chain and seat. All parts are needed to make the complete bicycle. The importer says each part should be classified separately as a 'part of bicycle'. How should the goods be classified?

Show the solution

Provision: Rule 2(a) says a heading for an article also covers the article unassembled or disassembled when presented that way.
Facts: The consignment contains all parts of one complete bicycle, in a single shipment, ready to be assembled.
Application: The heading for bicycles, read with Rule 2(a), covers the bicycle presented disassembled. Rule 2(a) therefore takes precedence over classifying the parts separately as 'parts of bicycles'. The disassembled bicycle is treated as the assembled bicycle.
Subheading: apply Rule 6 to pick the correct subheading within the bicycle heading.

Answer: Classify the whole consignment as a bicycle under the heading for bicycles (via Rule 2(a)), not as separate parts. Then choose the subheading under Rule 6.

Example 2

A retail gift set contains a cotton towel, a bar of soap and a bottle of shampoo, packed together in one box for sale to consumers without repacking, as a bathing gift. The set is not covered by any single heading. The towel is the largest item by value and bulk, and it is the item the gift set is built around. How should the set be classified?

Show the solution

Provision: Rule 1 gives no heading for the set as such. Rule 2 does not help, as this is not an incomplete or unassembled article.
Rule 3(a): no heading is more specific for the whole set.
Rule 3(b) covers goods put up in sets for retail sale. First check the set conditions: the goods must fall under at least two different headings, be put up together to meet a particular need, and be packed for direct sale without repacking.
Check of conditions: the towel, soap and shampoo fall under different headings, they serve one need (bathing), and they are packed in one box ready for sale to consumers. The set conditions are met.
Essential character: on these facts the towel is the largest component by value and bulk and is the centre of the set, so it gives the set its essential character. Essential character may depend on factors such as value, bulk, weight or role, and must be judged on the facts given.
Conclusion: the set goes under the heading for the towel.

Answer: The set meets the Rule 3(b) conditions for a retail set. Classify it under the heading for the cotton towel, as the towel gives the set its essential character on the stated facts.

Exam tips

Write the rule number every time. Marks usually go for naming the right rule and why the earlier ones fail.
In case-scenario MCQs, check whether the facts mention parts, sets or mixtures. Those words signal Rules 2 and 3.
Quote the Section or Chapter Note when an exclusion decides the matter. It is a Rule 1 point.
When asked about packing, check if it is specially shaped, durable and presented with the article (Rule 5(a)), or ordinary packing that follows the goods (Rule 5(b)).
Finish with the heading and, where asked, the subheading under Rule 6.

Practice questions from Classification of Imported and Export Goods

General Rules for Interpretation of the Tariff: frequently asked questions

What are the six General Rules of Interpretation?

Rule 1 uses heading terms and Notes. Rule 2(a) covers incomplete or unassembled articles. Rule 2(b) extends a heading for a material to goods consisting wholly or partly of that material, including mixtures and combinations. Rule 3 applies whenever goods appear classifiable under two or more headings. Rule 4 covers the most akin goods, Rule 5 covers packing, and Rule 6 covers subheadings.

Can I use Rule 3 before Rule 1?

No. The rules are applied in order. You move to a later rule only when the earlier one does not give a classification.

What is essential character?

It is the feature that gives goods their main identity. It may depend on the nature of the material, bulk, quantity, weight, value, or the role of a component. It is used mainly under Rule 3(b). Under Rule 5, packing follows the goods only as set out in the rule, and Rule 5(a) does not apply where the packing gives the whole its essential character.

When do I use the residuary entry?

Use it only when no specific heading or subheading fits the goods. Check the Notes and every specific entry first.
