If you’re shipping internationally, HS codes for shipping are one of the most important and most misunderstood parts of customs compliance.
A single incorrect digit in your classification can mean delays at the border, unexpected tariffs, or even fines. And in 2026, with increasing scrutiny on cross-border shipments and changes to de minimis thresholds, getting HS codes for shipping right matters more than ever.
This article breaks down what HS codes are, how they work, and how to classify your products correctly so you can move goods faster and avoid costly mistakes.
What Are HS Codes for Shipping?
An HS code (Harmonized System code) is a standardized numerical system used globally to classify traded products. Every product shipped internationally from apparel to electronics must be assigned the correct HS code.
Why Accurate HS Code Classification Is Critical in 2026
One of the most important reasons why accurate product classification is crucial for international shipping is compliance with customs regulations. Each country has its own set of rules and regulations governing the import and export of goods, and these rules can vary widely depending on the product being shipped. If a shipment is incorrectly classified, it may be held up at customs or even rejected, leading to costly delays and potential fines.Global trade has changed significantly in the past few years and HS code accuracy is now under greater scrutiny.
Tariffs Are Increasingly Complex
Tariffs are becoming more nuanced, and your HS code now directly determines far more than just a baseline duty rate. It impacts eligibility for free trade agreements, exposure to additional tariffs like anti-dumping duties, and overall landed cost accuracy. A misclassification doesn’t just create a small error but it can result in overpaying duties or underpaying them, both of which introduce financial risk and potential compliance issues.
De Minimis Changes Are Raising the Stakes
De minimis thresholds once allowed many low-value shipments to bypass duties altogether, making classification less critical for smaller parcels. That’s quickly changing. More countries are tightening these thresholds and requiring detailed shipment data upfront, meaning even low-value ecommerce shipments now often require accurate HS codes. In practice, this makes proper classification essential across all order values and not just high-ticket shipments.
Customs Is More Data-Driven Than Ever
Customs authorities are increasingly relying on automated systems, pre-arrival data screening, and AI-driven anomaly detection to assess shipments before they even arrive. This means inconsistencies between HS codes, product descriptions, and declared values can trigger flags almost instantly, leading to delays or inspections. To keep up, many brands are turning to automation tools to classify HS codes more accurately, reduce errors, and streamline global ecommerce operations. Learn how Passport uses AI to automate HS code classification, to improve compliance accuracy, reduce delays, and help brands scale global ecommerce faster.
What Happens If You Use the Wrong HS Code?
Using the wrong HS code can lead to a range of costly and disruptive consequences across your supply chain. Shipments may be delayed or held for inspection at customs, slowing down delivery timelines and impacting customer experience. Financially, misclassification can result in overpaying duties, cutting into your margins, or underpaying, which can trigger penalties, fines, or even audits from customs authorities. In more severe cases, goods can be seized altogether, and you may lose access to preferential trade agreement benefits that reduce costs. For high-volume shippers, even minor classification errors can quickly compound, creating significant financial exposure and operational inefficiencies at scale.
How to Classify Products Using HS Codes
Examples of HS Codes for Common Products
Cotton T-shirts → 6109.10
Smartphones → 8517.13
Face creams → 3304.99
Nutritional supplements → 2106.90
Even small classification errors can lead to delays or unexpected tariffs—so validating your HS codes is critical before shipping internationally.
How to Find the Right HS Code
There are several ways to perform an HS code lookup, but accuracy depends on how you search.
Where to Look
- Worldwide: WCO HS Nomenclature
- European Union: TARIC Consultation
- The United states: USITC HTS Search Engine
- Canada
- Australia
- National trade platforms
- Trade compliance platforms
Note: When searching, always find the correct 6-digit subheading first via the WCO. This code is harmonized globally, meaning it is the same in all countries. Only after confirming the 6-digit root should you look up the 8-to-10 digit national code in the specific country’s database. This “Rule of 6” prevents the most common misclassification errors that lead to customs delays.
Best Practices
- Use detailed product descriptions, not generic terms. Search for Function, Not Name. Example: “Women’s trousers, of synthetic fibers, knitted” (HS 6104.63).
- Keep a record of which General Rule of Interpretation (GRI) you used to justify your classification. This is your primary defense during a CBSA or CBP audit.
- Compare multiple sources
- Avoid relying solely on supplier-provided codes
- For US imports, use the CBP CROSS database to see if customs has already issued a binding ruling for a similar product.
How Product Classification Affects Your Landed Cost
In addition to compliance with customs regulations, accurate product classification can also help e-commerce merchants save money on duties and taxes. Your HS code plays a direct role in determining your total landed cost, influencing not just import duties but also VAT or GST and any additional tariffs or restrictions applied to your goods. Customs duties and taxes are based on the value of the goods being shipped, as well as their classification and country of manufacture. If a product is misclassified, it may be subject to higher duties and taxes than necessary, resulting in unnecessary costs for the merchant.When classification is done correctly, it ensures you’re paying the appropriate amount and taking full advantage of available cost-saving opportunities.
How Passport Helps to Get HS Codes Right
Classifying your products for U.S. import sounds like a logistics task. It’s actually a legal one. Under U.S. law, determining an eight- or ten-digit Harmonized Tariff Schedule (HTS) code for a specific imported product is considered “customs business”—and customs business can only be performed by a licensed customs broker. That’s been CBP’s position for years. But a January 2026 ruling (HQ 350722) made it harder to work around.
The ruling explicitly extended this requirement to AI and automated classification tools. Software alone—no matter how sophisticated—cannot legally produce the HTS subheadings used for actual import entries. Without licensed broker oversight, that classification is non-compliant. Full stop.
This catches a lot of brands off guard, especially those using tech-forward compliance platforms that make the process look seamless. The automation isn’t the problem. It’s relying on it as a legal substitute rather than a support tool. A licensed broker still needs to be in the loop, and knowing that upfront saves you from a costly correction later.
Managing HS code classification at scale is inherently complex, especially when selling across multiple markets with different regulatory requirements and tariff structures. As a licensed and permitted U.S. customs broker, Passport offers commodity classification as a complimentary service to all our brand partners. Our brokers can work through your product catalog in bulk or classify individual items transactionally, depending on what you need. Either way, you get accurate codes, reduced duty exposure, and a compliance workflow that doesn’t slow you down. Done well, classification stops being a cost center and starts being a competitive edge—one less thing standing between you and confident global scaling.

Frequently Asked Questions
What is an HS code in shipping?
An HS code (Harmonized System code) is a standardized numerical code used worldwide to classify traded goods. It helps customs authorities identify products, apply the correct duties and taxes, and ensure shipments comply with regulations.
How do I find the correct HS code for my product?
You can find your HS code by using official government databases, customs websites, or HS code lookup tools. The process typically involves identifying your product’s material, function, and use, then narrowing it down through the appropriate category and subcategory.
Are HS codes the same in every country?
HS codes are standardized globally at the first 6 digits. However, many countries extend them to 8–10 digits for more detailed classification, meaning the full code can vary depending on the destination country.
What happens if I use the wrong HS code?
Using an incorrect HS code can lead to customs delays, incorrect duty payments, fines, audits, or even shipment seizure. It can also result in missing out on reduced tariffs under trade agreements.
Do all shipments require an HS code?
For commercial shipments, yes. And with recent de minimis changes, even lower-value shipments that previously cleared informally now often require proper HS classification.
What is the difference between HS codes and HTS codes?
HS codes refer to the globally standardized 6-digit classification system, while HTS refers to the Harmonized Tariff Schedule of the United States (HTSUS), a country-specific extension.
Can HS codes impact shipping costs?
Yes. HS codes directly affect duties, taxes, and eligibility for trade agreements, all of which contribute to your total landed cost.
How often do HS codes change?
The World Customs Organization updates the HS system approximately every five years, but countries may update their extended codes more frequently. It’s important to stay current to ensure compliance.
Can I reuse the same HS code for all markets?
Not always. While the first 6 digits are consistent globally, additional digits and classification nuances can vary by country, so it’s important to validate codes for each destination.
