Use the GST Portal’s Services > User Services > Search HSN Code tool to find candidate classifications, then match the result to the actual goods or service and verify its rate and conditions in the applicable CBIC GST rate schedule. A product’s everyday name alone is not enough to establish its code or rate: details such as material, construction, function, or weight can affect classification.
The practical sequence is to describe the real supply accurately, use the portal to find possible HSN or SAC entries, and then verify the relevant full entry and any conditions in CBIC’s schedule. Treat a search match as a lead to check, not as a final ruling. If more than one entry appears plausible after comparing the facts, review CBIC’s FAQs and current notifications or ask a qualified tax professional.

HSN and SAC: which code do you need?
HSN refers to the classification system used for goods. Services use service classification codes, commonly called SAC. The GST Portal’s Search HSN facility covers both goods and services, so select the correct type of supply before searching.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The code is only one part of the lookup. A search result is a candidate to investigate, not a binding decision about how a particular supply must be classified. The applicable rate depends on the relevant legal schedule entry, including any attached conditions or exceptions.
#1 Best Overall
Start by identifying what is actually being supplied. A business or invoice label may describe a product line, a customer-facing name, or a broad activity, rather than the specific goods or service being classified. The classification exercise concerns the supply itself and the characteristics that distinguish it in the relevant description. For goods, that may include composition, construction, intended function, or another stated attribute. For services, describe the service delivered rather than relying only on the name of the business providing it.
HSN and SAC are not interchangeable labels for the same thing. Selecting “goods” when the supply is a service, or the reverse, can produce irrelevant candidates. If a transaction involves different supplies, identify the supply you are classifying and use the appropriate search type for it.
What to gather before you search
Write down a description of the actual supply that is more precise than its shop or invoice name. A supplier’s trade name may not match the technical wording used in the tariff or rate schedule. Gather the details that could distinguish one entry from another:
- Whether the supply is goods or a service.
- For goods, what the item is made from and how it is constructed.
- Its function or intended use, where relevant to the description.
- Any other characteristic mentioned in a possible schedule entry, such as fibre or weight.
- For services, a clear account of what is being provided rather than only the business or invoice label.
These facts help you decide whether a suggested technical description really fits. They also make it easier to compare two plausible entries without treating a broad product name as decisive.
Before searching, separate facts from assumptions. Record what the item is made from, its construction, and what it does; do not infer those characteristics from its brand or common name. If an entry turns on a particular detail, such as a material or weight, use the actual product information rather than a guess. For a service, identify the activity supplied in plain language and note what is included, where that helps describe the service accurately.
A useful working description often has two parts: the familiar name people use and the technical characteristics that explain what the supply is. For example, if a common name could refer to items made from different materials, keep the material detail with the name when searching and comparing results. The point is not to make the description sound legalistic; it is to avoid losing a distinguishing fact when translating an everyday description into a technical one.
How to find a candidate HSN or SAC code on the GST Portal
- Open the GST Portal. Go to Services > User Services > Search HSN Code. GSTN’s advisory describes the facility as available both before and after login.
- Choose the search mode. Search by HSN if you already have a candidate code. If you are starting from a name or description, choose description search and specify whether the supply is goods or services.
- Enter a useful description. Try a trade, commercial, or technical term, or a meaningful part of a description. If a familiar name gives poor or overly broad matches, try describing the material, construction, or function instead.
- Review the suggested code-description pairs. Read the technical description alongside the code. Do not select a result solely because its wording resembles the product name.
- Compare the result with the real supply. Check its composition, construction, function or use, and any other distinguishing details against the candidate description. Keep more than one candidate under consideration if the facts do not clearly distinguish them.
GSTN describes the search tool as helping users map familiar descriptions to technical descriptions and nearby HSN codes. Its suggestions are a useful starting point, but they do not replace checking the applicable legal entry.

Review the returned description and compare it with the supply you are handling now. A previously used code may have been selected for a different product variant, service, or factual description.
If you are starting with a product name, try the common trade name first, then refine the search with a more specific term if the result list is broad or does not seem to describe the actual item. A material, construction detail, or function can help bring the description closer to the technical wording. For a service, search using a concise description of the service activity; the name of the provider or its general industry may not describe the particular service supplied.
Read each suggested pair together. The code helps identify a classification candidate, while the accompanying description helps you judge whether that candidate is relevant. Do not stop after seeing a familiar code, and do not choose a result merely because one word matches. If the portal provides multiple plausible descriptions, note them for the next step instead of forcing a choice before comparing the full facts and legal entries.
When a search does not produce a clear match, that is a reason to improve the description or consult the schedule, not a reason to adopt the closest-looking result automatically. GSTN’s advisory notes that common trade descriptions and technical tariff descriptions may differ. A search tool can help bridge that wording gap, but it cannot determine facts that the user has not supplied or resolve every classification question on its own.

1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsHow to verify the GST rate and its conditions
- Open CBIC’s GST Goods and Services Rates schedule. Use the goods or services section appropriate to the supply.
- Find the entry that matches the candidate classification. Read the full description, not just the heading or code. Confirm that the wording covers the item or service as actually supplied.
- Read the entire entry, including conditions and cross-references. A rate may be attached to a description with an exception, qualification, or other condition. A code or broad chapter by itself does not establish the rate.
- Check current notifications and clarifications. Rates and compliance rules can change. Confirm that the schedule entry remains current before relying on it for an invoice or return.
CBIC’s rate FAQs can help when descriptions appear close or a product characteristic may matter. Use them alongside the schedule and relevant current notifications; an example in an FAQ is not a universal classification rule.
Do not infer a rate from a code’s broad chapter or heading alone. The schedule entry’s wording and any conditions attached to it are part of the answer. Compare the full description with the supply and make sure that a qualification, exception, or cross-reference does not change which entry applies. If a schedule row is conditional, the condition is not optional background: it may be central to whether that row describes the supply.
Keep classification and rate verification as related but distinct checks. First ask whether the description and code are appropriate for the actual supply. Then establish which schedule entry applies and what rate and conditions that entry states. A plausible code does not by itself confirm the rate; conversely, finding a rate that seems familiar is not enough to establish that the supply belongs in that entry.
For an entry that points to another provision or includes qualifying language, follow the cross-reference and read the relevant text rather than stopping at the first matching line. If the wording is unclear or the candidate depends on a fact you cannot establish, check current CBIC notifications or clarifications and seek qualified advice when the decision is material or disputed.
Why similar products can have different classifications
Classification turns on the tariff description and the facts of the supply, not just on what consumers call an item. CBIC’s GST rate FAQs illustrate how attributes can separate otherwise similar-looking cases:
- Sarees and dhotis: the examples distinguish classifications by constituent fibre and, in the cotton examples, weight.
- Solar panel mounting structures: the examples distinguish structures made of iron or steel from those made of aluminium.
These examples show why a name-only search can mislead; they do not determine the classification of every saree, dhoti, or mounting structure. Apply the relevant description to the particular item and check the current schedule.
The lesson from the saree and dhoti examples is not simply that all textiles should be classified by weight, nor that a fibre label settles every case. Rather, the FAQ illustrates that the constituent fibre and, for the cotton examples, weight can matter to the distinction being discussed. A reader checking a textile should therefore compare the relevant facts with the actual schedule wording rather than assuming that two products with the same everyday name share a classification.
The mounting-structure examples likewise show that the material distinction in the described cases matters: CBIC’s FAQ treats iron or steel structures differently from aluminium structures. That does not establish a universal rule for every item used with a solar panel. The actual construction and the wording of the applicable entry still need to be checked. These examples are practical reminders to inspect the features named in a candidate description, not substitute classifications for an individual product.

Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →More generally, if two items look alike to a buyer but differ in a fact named in the schedule or FAQ, do not assume they necessarily share a code or rate. Conversely, a difference that is not relevant to the wording should not be treated as decisive merely because it seems commercially important. The task is to compare the real supply against the legal description and the characteristics that description makes relevant.
What to do when several results look plausible
Compare the candidates against the same set of facts before choosing one. A practical comparison should cover:
- The exact goods or service description in each candidate entry.
- Material, composition, and construction for goods.
- Function or intended use where the wording makes it relevant.
- The legal schedule description and heading, not only a portal search label.
- The rate and all conditions, exceptions, or cross-references attached to the entry.
- The date and applicability of the notification governing the entry.
If the short description leaves materially different candidates open, consult CBIC’s GST rate FAQs and relevant current notifications or clarifications. For a significant or disputed classification, get advice from a qualified tax professional rather than treating a search suggestion as a final ruling.
A simple side-by-side comparison can prevent a superficial match. For each candidate, write down the exact schedule description, the product or service facts that appear to support it, the facts that appear inconsistent with it, and any condition that must be met. For goods, compare composition and construction explicitly; for either goods or services, consider the function or use if the entry makes it relevant. Then compare rates only after identifying the entry that best fits the actual supply.

If two candidates remain plausible, avoid resolving the uncertainty by choosing the lower, more familiar, or previously used rate. Those are not classification tests. Read the corresponding CBIC FAQ examples and current notifications or clarifications for guidance on the distinction. If the remaining ambiguity could materially affect an invoice or tax treatment, ask a qualified tax professional to review the facts and entries. A professional review is particularly useful when the factual description is incomplete or the relevant entries contain conditions that are difficult to interpret.
Keep the comparison anchored to the version of the rule that applies to the date of the supply. CBIC’s rate schedule and notifications are the appropriate places to check for current terms, while older examples or press releases can provide context only to the extent that they remain applicable. Record the date of the schedule or notification checked so a later review can distinguish the decision made at the time from a subsequent update.
Invoice digit requirements: treat older guidance as dated
A CBIC press release from 2021 stated that, effective 1 April 2021, taxpayers whose preceding-financial-year turnover was above ₹5 crore had to furnish six-digit HSN or SAC codes on invoices for taxable supplies. That is what the dated release reported; it should not be assumed to state the current requirement in 2026. Check the latest CBIC notifications and current GST Portal guidance before deciding which digit rule applies to an invoice.
The threshold and digit count above are a statement of the 2021 press release, not a current-rule summary. Before preparing an invoice, verify the presently applicable reporting requirement, including the relevant turnover measure, code digits, and the supplies covered. Do not carry an old invoice format forward just because it worked previously, and do not assume the 2021 statement answers every invoice-format question today.
Recommended Free Tools
For recurring invoicing, make the live-rule check part of the process rather than relying indefinitely on a saved note or a prior year’s setup. If an organisation uses accounting or invoicing software to store product classifications, the software can help apply information consistently, but it does not establish whether the selected classification or rate is legally correct. The free GST Portal and CBIC schedule remain the primary places to look up and verify the classification and rate.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.A final check before using the code
- Does the classification describe the actual supply, including relevant composition, construction, use, or service details?
- Did you verify the full applicable entry in the CBIC rate schedule rather than infer a rate from a code alone?
- Have you read the entry’s conditions, exceptions, and cross-references?
- Have you confirmed current notifications and invoice requirements rather than relying on older guidance?
- If meaningful ambiguity remains, have you sought qualified advice before relying on the classification?
Keep a record of the description and facts you relied on, the candidate you checked, and the schedule entry and current guidance used to verify it. That makes it easier to review the decision if the supply changes or the applicable rules are updated.
A useful record can be concise: the item or service description, the relevant characteristics, the candidate code and technical description, the CBIC entry reviewed, and the date of the schedule or notification check. If you considered another plausible candidate, note why the chosen entry better matched the facts. This is especially helpful when different product variants share a trade name or when a service description changes over time.
Repeat the check when the supply changes in a way that may affect its description, when a new variant is introduced, or when current notifications or the schedule are updated. Do not assume that a classification remains suitable just because the same customer-facing name is still being used. The relevant question is whether the facts and applicable entry continue to match.
For a one-off lookup, the process is straightforward: describe, search, compare, and verify. For repeated invoicing, a consistent internal record can make future checks easier, but it should not replace checking current rules. If the description remains ambiguous after reviewing the portal results and CBIC materials, escalate the issue rather than letting an uncertain code become an unexamined default.
Frequently Asked Questions
How do I find the GST rate for a product?
First identify the product’s relevant characteristics and use the GST Portal’s Search HSN Code facility to find candidate descriptions. Then match the actual product to the full goods entry in CBIC’s GST Goods and Services Rates schedule. Read any conditions, exceptions, and cross-references, and check current notifications before relying on the rate.
How can I check an HSN code by product name?
On the GST Portal, open Services > User Services > Search HSN Code, choose description search, select goods, and enter the product’s trade, commercial, or technical name. If the matches are too broad, refine the description with relevant details such as material, construction, or function. Treat the returned code-description pairs as candidates and verify the technical description against the actual product and CBIC schedule.
How do I find the SAC code for a service?
Use the same GST Portal Search HSN Code facility, but select services when choosing the supply type. Describe the service actually provided rather than relying only on the provider’s business name or invoice label. Review the suggested description and verify the applicable service entry and conditions in CBIC’s current rate schedule.
Does the GST rate depend on what a product is made of?
It can, if material or composition distinguishes the applicable entry. CBIC’s rate FAQs illustrate this with solar panel mounting structures made of iron or steel versus aluminium, and with textile examples where constituent fibre matters. These examples are not universal rulings; compare the actual product with the relevant schedule description.
Can I rely on the GST Portal search result as a final classification?
No. GSTN describes the tool as helping users map familiar descriptions to technical descriptions and nearby HSN codes. A result is a useful candidate, but you still need to match its full description to the actual supply and verify the legal entry, rate, and conditions in CBIC materials.
What invoice code digits are required?
A CBIC press release from 2021 reported that, from 1 April 2021, taxpayers with preceding-financial-year turnover above ₹5 crore had to furnish six-digit HSN or SAC codes on invoices for taxable supplies. That is dated guidance, not a guarantee of the current rule. Check current CBIC notifications and GST Portal guidance for the requirement that applies to your invoice.
What should I do if two HSN or SAC entries seem to fit?
Compare the full legal descriptions, relevant material or construction, function or intended use where applicable, rate, and all conditions or cross-references. Consult CBIC’s rate FAQs and current notifications or clarifications. If the classification remains materially ambiguous or disputed, seek advice from a qualified tax professional rather than choosing the closest search result.
