How Do I Find My Product's HS Code?

Finding the correct HS code is not always straightforward. Many products could fit multiple classifications, and the difference in duty rates can be significant.

This guide walks you through four practical ways to find the right HS code for your products, from the easiest to the most authoritative.

What Is an HS Code?

The Harmonized System is an international standard for classifying traded goods. It is maintained by the World Customs Organization (WCO) and used by over 200 countries.

Every product imported into any country must be classified under an HS code. The code determines:

• Duty rate - The percentage of value you pay as import duty
• Trade restrictions - Whether the product requires licenses, permits, or is prohibited
• Trade statistics - How imports and exports are tracked globally
• Free trade agreement eligibility - Whether preferential rates apply

The first 6 digits are standardized internationally. Countries add their own digits for more specific classification, making codes 8-10 digits in most countries.

Why the Right Code Matters

Classification mistakes are expensive. Using the wrong HS code can result in:

• Overpaying duty - Your product might qualify for a lower rate under the correct code
• Underpaying duty - Customs can audit past entries and demand back-payment plus penalties
• Clearance delays - Incorrect codes may trigger inspections or holds
• Trade compliance issues - Some codes have restrictions that require documentation

4 Ways to Find Your HS Code

1. Ask Your Supplier

The easiest starting point. Your supplier exports the same products to other customers and likely knows the HS code that is typically used.

How to do it: Ask for the HS code on your proforma invoice or commercial invoice. Many suppliers include it automatically.

Reliability: Medium. Supplier codes are a good starting point but may not be correct for your specific country. Export codes from China do not always match import codes in Australia or the US because countries extend the 6-digit base differently.

Best for: Getting a baseline to verify through other methods.

2. Check Past Shipments

Use your own history. If you have imported the same or similar products before, the HS code should be on your previous customs entry documents.

Where to find it:

• Customs entry documents from your broker (often PDF or paper copies)
• Broker portal or online account
• Import declaration forms (B3 in Canada, Entry Summary 7501 in US)

Reliability: High, if the product is identical. Your broker has already classified it and customs has accepted it.

Caution: Do not use a past code for a different product just because it seems similar. Even small differences in materials or use can change the correct classification.

3. Use Official Tariff Lookup Tools

Search the tariff schedule directly. Every country publishes its tariff schedule online, and many have search tools.

How to use them:

1. Start with a keyword search (e.g., "cotton t-shirt")
2. Browse the results to find descriptions that match your product
3. Read the section and chapter notes carefully
4. Note the duty rate for each potential code

Reliability: High for finding options, but choosing between similar codes requires understanding the classification rules.

4. Ask Your Customs Broker

The most reliable method. Licensed customs brokers are trained in tariff classification and work with HS codes daily.

When to use this:

• New products you have never imported before
• Products that could fit multiple classifications
• High-value shipments where the duty rate matters
• Products with potential trade restrictions

How to ask: Send your broker product descriptions, photos, material composition, and intended use. The more detail you provide, the more accurate their classification will be.

Cost: Many brokers will classify products for free if you are using their clearance services. Some charge a small fee for standalone classification consultations.

Understanding HS Code Structure

HS codes follow a hierarchical structure that gets more specific as digits are added:

• Chapters (2 digits) - Broad product categories (97 chapters total)
• Headings (4 digits) - Narrower product groups within chapters
• Subheadings (6 digits) - Internationally standardized, same worldwide
• National digits (8-10 digits) - Country-specific subdivisions

When researching HS codes internationally, focus on the first 6 digits. The extended digits vary by country.

Common HS Code Mistakes

These classification errors come up frequently:

Classifying by use instead of composition

A "sports bag" is not classified under sports equipment. It is classified by material (leather, plastic, textile) under the bags chapter. What the product is made of often matters more than what it is used for.

Using the supplier's export code without verification

Your Chinese supplier's export code is a starting point, not the final answer. Import codes in your country may differ, and the supplier has no liability for your customs compliance.

Choosing the code with the lowest duty rate

If your product genuinely fits multiple codes, you may choose the most favorable one. But intentionally misclassifying to reduce duty is fraud. Customs audits happen, and penalties are steep.

Ignoring material composition

A bag that is "90% cotton, 10% leather trim" may classify differently than one that is "90% leather, 10% cotton lining." Material percentages matter.

Verifying Your HS Code

Before committing to an HS code, verify it through multiple sources:

1. Cross-check the description - Does the official description actually match your product?
2. Read the section and chapter notes - These define what is included and excluded from each classification
3. Check the duty rate - Verify it against the official tariff schedule
4. Ask your broker - Confirm they agree with the classification
5. Document your reasoning - Keep notes on why you chose this code in case of audit

Getting the HS code right at the start saves problems later. A few minutes of verification now prevents duty reassessments, penalties, and clearance delays down the road.
