2026 International & US HS Code & Harmonized Tariff Code Lookup

Use this Customs Duties calculator to find the six-digit Harmonized Codes for international shipping and accurately classify your goods for global trade.

What is an HS or HTS Code?

HS Codes (or HTS Codes), also known as the Harmonized Commodity Description and Coding System, or simply the Harmonized System, are a standardized international system to classify globally traded products. The system was first implemented in 1988 and is currently maintained by the World Customs Organization. The HS Convention, signed in 1983, has over 205 member countries. As signatories, each country agrees to classify its HS tariff code and duty structure according to the HS Code categories.

The Harmonized System is used to ease global trade by creating unified categories to classify different types of goods.

The Harmonized System categorizes about 5,000 commodity groups in simple six-digit codes, broken down into 21 Harmonized System sections, 96 Harmonized System chapters, and thousands of headings.

HS Codes Structure

Global & US HS Codes have four components. Referring to the diagram’s green numbering:

1. Chapter

There are 21 distinct sections that split into 96 chapters. Exception chapters include chapter 77, which is reserved for future use, chapters 98 and 99, which are limited to national use, and Chapter 99, which is a specific code limited to temporary modifications. In the above example, the chapter selected is 09, for “Coffee, tea, maté and spices”.

2. Heading

The heading dictates the specific category within any particular chapter. In the example above, the 01 refers to coffee.

3. Sub-heading

The last two digits of the international Harmonized Code are more specific, defining subcategories of products. For example, caffeinated coffee beans are 0901.21, but decaf is 0901.22. Incidentally, instant coffee would fall under a totally different heading – 21 – for miscellaneous edible preparations.

4. Extra digits

Countries can use an additional 2-4 digits for country-specific categorizations. For example, the US HS code relies on ten digit codes called Schedule B numbers. The 0050 in the above example is used for non-organic coffee. Since these digits are unique, non-organic caffeinated coffee in another country would begin with the same 6 digits but the last four digits would likely be different.

USA HS and HTS Codes

In the USA, exports and imports each have their own numbering system:

USA Harmonized Tariff Schedule codes (HTS-US ) are used for import categorization. Use this number for import paperwork and electronic filing.
Schedule B codes are used for export categorization. Use this number for export paperwork and EEI filing.

As a signatory to the HS Convention, the USA uses the six-digit HS System categorization. However, for determining duty rates and statistical purposes, some countries break the classification down further by adding 1-4 numbers after the six digits. These numbers are called Harmonized Tariff Schedule (HTS ) codes.

HS Code Search & Lookup

There are 21 Harmonized System Sections – the highest level of customs tariff code categorization. This HS code list is used to unify broad categories, like different types of vegetables (Section II, chapters 6-14). These sections are dictated by the WCO and are unified across every member country. The 21 HS Code sections include the following:

HS and HTS Codes Purpose

HS and HTS Codes are used by customs and logistics providers for a variety of purposes, from calculating duties and tariffs to ensuring that an importer is not importing banned or hazardous products. The true value of HS Codes is how globally recognized they are. Whether you’re importing purebred horses to the United States or Sri Lanka, the first six digits of that HS Code will be 0101.21.

HS Codes for Export and Import

That’s exactly where Freightos’ Harmonized Code Duty Calculator comes in handy. Just head to the top of this page, start entering the product you’re shipping into the HS Code Finder, and the calculator will pull results from the customs HS tariff codes list. Since the Harmonized System Code uses very specific words, it may be easier to browse HS codes instead of searching.

Once you find the right HS code, enter the value of your shipment. The HS Code calculator will tell you exactly what the required US duties are. If you encounter a problem, just report the bug with the calculator tool and we’ll be sure to fix it as quickly as possible.

How to get your HS Code

Our HS Code calculator will help you get started finding your HS code. Typically though, once you have goods ready to ship, your supplier will provide you with an HS code – but always check to make sure. In addition, it’s a good idea to reach out to your freight forwarder or customs broker to make sure your HS code is accurate – or if your supplier does not provide one.

Note: some goods can potentially use a few different HS codes. Your freight forwarder or customs broker can also help you choose the one with the lowest possible customs rates for your goods.

The New Economics of Logistics Visibility

Published

on

By

Knowing that a shipment will arrive six hours late is information. Knowing it early enough to reschedule labor, protect a customer commitment, avoid detention, or change an inventory decision is economic value.

That distinction is becoming central to the logistics visibility market. The earlier argument that exceptions are becoming the real unit of work explains why visibility economics depend less on event volume than on whether the organization can convert important events into timely resolution.

The first era of visibility was largely about answering a basic question: Where is my shipment? The next era is about a harder question: What should I do because its state has changed?

Visibility Is Not the Outcome

Location and status data can be valuable, but they are intermediate products. A business does not earn a return because a dot moved across a map more accurately. The return appears when information changes an operational decision. A useful way to think about visibility is as a chain: signal -> interpretation -> decision -> intervention -> economic outcome. If any link is missing, much of the potential value disappears.

A Signal Has to Arrive Inside the Decision Window

Timing matters.

A delay discovered after the customer has already missed production is history. The same delay identified early enough to expedite an alternate shipment may be actionable. An ETA update received after warehouse labor has reported for a shift may have less value than the same update received while the schedule can still be changed.

This means visibility quality is not only about accuracy. It is about whether the signal arrives with enough lead time to support an intervention.

Not Every Exception Deserves Attention

As visibility improves, organizations often discover a new problem: too many exceptions. A network with thousands of shipments will always contain delays, deviations, missed scans, changing ETAs, and incomplete data. If every deviation creates an alert, planners become the bottleneck. The more important capability is prioritization.

Which late shipment threatens a high-value order? Which delay creates a stockout? Which container risks demurrage? Which arrival change will disrupt a dock schedule? Which event is likely to self-correct without intervention?

Visibility becomes intelligence when the system can distinguish operational consequence from mere deviation.

ETA Is a Decision Input

Estimated time of arrival is a good example of how the economics are changing. ETA was once primarily a customer-service or tracking metric. Increasingly it can influence warehouse scheduling, yard planning, labor, inventory, customer promises, and downstream transportation. That makes ETA a shared operating variable.

The value increases when the prediction is connected to the systems that can respond. A changing ETA that remains trapped in a visibility dashboard creates less value than one that can trigger a workflow or decision elsewhere.

Dwell, Detention, and Demurrage Make the Economics Visible

Some visibility use cases have direct financial consequences. Better awareness of arrival, dwell, free-time windows, and container status can help organizations manage detention and demurrage exposure. Yard visibility can reduce unnecessary trailer search and moves. Earlier exception detection can protect delivery appointments and reduce costly service recovery. These cases make an important point: visibility value is often realized outside the visibility platform itself.

More Visibility Can Increase Work

This is the uncomfortable side of digital transparency. If a company exposes ten times as many events but does not improve prioritization or workflow, it may create ten times as many things for people to inspect. The result can be an expensive monitoring layer sitting on top of the same manual decision process.

That is why visibility and autonomous exception management are converging. The system must increasingly help decide which events require action, assemble context, recommend a response, and automate routine resolution where appropriate.

Measure Intervention, Not Just Coverage

Visibility programs are often measured by tracking coverage, data completeness, ETA accuracy, or number of connected carriers. Those are necessary operating metrics, but they do not fully describe business value.

Organizations should also ask: How many material exceptions were identified early enough to act? How quickly were they resolved? How often did intervention protect service or avoid cost? How many alerts required no useful action? How much planner time was consumed per exception?

Those measures connect visibility to economics.

The Market Is Moving Toward Action

This shift has strategic implications for technology providers. Pure visibility is becoming less differentiated as location and event data become more widely available. The higher-value layer is interpretation and action: understanding what an event means to a specific operation and helping execute the appropriate response.

That pushes visibility platforms toward orchestration, workflow, decision intelligence, and AI. It also pushes TMS, WMS, and other execution systems toward richer external event awareness.

The Bottleneck Moves

For years, logistics organizations complained that they could not make better decisions because they could not see what was happening. Increasingly, they can see more.

The bottleneck is moving.

When a network can identify exceptions continuously, the constraint becomes the speed and quality with which the organization can interpret and resolve them. That is precisely the environment in which AI agents become interesting—not because logistics needs another conversational interface, but because it needs more capacity to do operational work.

o9 Solutions Uses a Knowledge Graph to Connect Supply Chain Decisions

Published

By

Supply chain decision-making is difficult partly because the relevant information is distributed across products, locations, suppliers, orders, capacities, policies, and external events. A system may have access to all of those records and still struggle to understand the relationships among them quickly enough to support a consequential decision.

o9 Solutions addresses that problem through its Digital Brain architecture, including an enterprise knowledge graph and in-memory modeling designed to connect demand, supply, inventory, planning, and operating context. That semantic layer is important because it gives analytics and AI a structured representation of how supply chain entities relate to one another rather than treating the environment as a collection of independent tables and documents.

The company combines this architecture with integrated planning, optimization, scenario modeling, machine learning, and human oversight. The strategic direction is toward a continuous decision environment where changes can be interpreted quickly, alternatives can be modeled, and recommendations can be traced back to the assumptions, events, and constraints that produced them.

As with any broad planning and intelligence platform, the value depends on implementation quality. Knowledge models need strong data governance, entity resolution, process ownership, and clear decision rights. A sophisticated model of the supply chain is useful only if the organization can keep it current and use it consistently in real operating workflows.

o9 Solutions appears in the Logistics Viewpoints Supply Chain Decision Intelligence MarketMap and Autonomous Exception Management MarketMap. The two MarketMaps highlight the relationship between integrated decision intelligence and the faster exception-response capabilities now developing around it.

AI Will Not Transform the Supply Chain Until the Architecture Around It Catches Up

Published

Executive thesis. The model is becoming the least durable layer of the AI stack. Sustainable advantage will come from the operating architecture around AI: authoritative context, governed tools, permissions, observability, and connection to enterprise workflows.

The model is only one component

Supply chain AI discussions often begin with model capability: prediction accuracy, reasoning quality, computer vision performance, or the fluency of a generative system. Those capabilities matter, but operational value depends on everything around the model. The system still needs authoritative context, enterprise tools, permissions, workflow, observability, and a reliable path from recommendation to action.

Different AI patterns solve different problems

Prediction, optimization, generative AI, vision, and agents should not be treated as interchangeable technologies. Forecasting demand, selecting a route, extracting information from a document, interpreting an image, and executing a multi-step workflow require different evidence, control, and performance measures. A mature architecture starts with the decision or task and chooses the AI pattern that fits it.

Context is the operating fuel

An AI system can produce a plausible answer while using stale or incomplete operational context. In logistics, that can be dangerous because the truth may reside across orders, inventory, rates, carrier status, warehouse state, supplier records, and policy documents. Retrieval, master data, identity resolution, and system access therefore become part of the AI architecture, not secondary data-engineering concerns.

Tool access turns intelligence into consequence

The moment an AI system can create a shipment, change an order, contact a carrier, release inventory, or approve an exception, governance becomes an operational requirement. Tool permissions, financial limits, approval gates, idempotency, retries, and rollback are the mechanisms that separate an interesting demonstration from a dependable production workflow.

Measure workflow performance

A fluent response is not the right success metric for operational AI. Supply chain leaders should measure decision latency, manual context gathering, exception closure, override behavior, error recovery, tool failure, and the business outcome being improved. That measurement discipline also creates a rational basis for expanding autonomy as evidence accumulates.

The Logistics Viewpoints AI in Logistics: Use Cases, Architecture, and Implementation Guide separates the major AI patterns and connects them to data, tools, governance, workflow, observability, and ROI—the architecture required to move from model capability to operating value.

Executive implication

AI strategy should separate model selection from control architecture and measure value through workflow performance, decision quality, and operational outcomes.
