Australian exporters shipping goods to the United States need to understand an important distinction:
HS, AHECC and U.S. HTS codes are related, but they are not identical.
Incorrect classification can affect:
• Customs declarations
• Import duty
• Section 232 and Section 301 measures
• AD/CVD
• Import controls
• Total landed cost
Classification should therefore be reviewed before the shipment leaves Australia.
What Is an HS Code?
HS means:
Harmonized System.
It is maintained by the World Customs Organization and provides an internationally harmonised:
6-digit
classification structure.
Countries can then add additional digits for their own tariff and statistical requirements.
As a result, the first six digits may align internationally while the remaining digits differ between Australia and the United States.
What Code Does Australia Use for Exports?
Australian export declarations use:
AHECC
Australian Harmonized Export Commodity Classification.
AHECC is based on the international six-digit HS structure and extends it to an:
8-digit Australian export classification.
Exporters should therefore identify the correct AHECC based on factors such as:
• Product description
• Material
• Function
• Manufacturing method
• Technical specification
A U.S. 10-digit HTS number should not simply be copied into an Australian export classification field.
What Is the U.S. HTS?
Goods imported into the United States are classified under the:
HTSUS
Harmonized Tariff Schedule of the United States.
The U.S. system builds on the international HS and includes additional tariff and statistical detail.
In simplified terms:
International HS = 6 digits
U.S. HTSUS = further U.S. tariff and statistical subdivisions
An Australian AHECC number and a U.S. HTSUS number therefore serve different national customs systems.
Why Does Detailed Classification Matter?
Tariff classification can depend on very specific product characteristics.
For metal products, this may include:
• Steel or aluminium
• Stainless or non-alloy
• Sheet or coil
• Hot-rolled or cold-rolled
• Width
• Thickness
• Processing method
For machinery and electronics, classification may depend on:
• Principal function
• Complete equipment or parts
• Electrical characteristics
• Material composition
Small product differences can result in different tariff classifications and different import measures.
Which U.S. Tariffs Should Australian Exporters Check?
U.S. landed cost should not be assessed using the base HTS rate alone.
Depending on the product and current trade measures, review may include:
• Base HTS duty
• AUSFTA preferential treatment
• Section 232 tariffs
• Section 301 measures
• Anti-Dumping and Countervailing Duties
• Other current U.S. trade measures
• MPF and HMF where applicable
The final result depends on:
HTS + Country of Origin + Product + Current Trade Measures.
A base HTS rate showing “Free” does not necessarily mean no additional U.S. duties apply.
Does AUSFTA Still Matter?
Yes.
The:
Australia–United States Free Trade Agreement
may provide preferential tariff treatment for qualifying Australian-origin goods.
However, FTA preference does not automatically remove every additional trade measure introduced separately.
Businesses should therefore review:
• AUSFTA Rules of Origin
• Base HTS treatment
• Additional tariffs currently applicable
Goods do not qualify as Australian origin simply because they are shipped from Australia.
Origin depends on the applicable rules and manufacturing circumstances.
What Is Section 232?
Section 232 is used by the United States for certain national-security-related import measures.
Depending on current measures, affected sectors may include products such as:
• Steel
• Aluminium
• Copper
• Automotive products
• Certain industrial goods
Businesses exporting metal-intensive products or machinery should therefore check whether the relevant HTS classification is covered by current Section 232 measures.
These rules can change, so they should be reviewed again before shipment.
What Is Section 301?
Section 301 measures can impose additional tariffs in response to specified trade practices.
While many businesses associate Section 301 primarily with China tariffs, the correct treatment should be checked against:
• Country of origin
• HTS classification
• Current measure
• Exemptions
• Effective date
Australian exporters should not assume that Australian-origin goods are automatically outside every Section 301 measure.
What Are AD/CVD Duties?
AD/CVD means:
Anti-Dumping Duties
and:
Countervailing Duties.
These measures can apply to specific:
• Products
• Countries of origin
• Producers or exporters
Rates can be substantially higher than ordinary customs duty.
Products such as metals, chemicals and industrial materials should therefore be checked against current AD/CVD orders where relevant.
What Other U.S. Import Fees May Apply?
U.S. imports may also incur customs user fees such as:
MPF — Merchandise Processing Fee
and, for applicable ocean imports:
HMF — Harbor Maintenance Fee.
Rates and thresholds can change, so the applicable fee schedule should be checked for the actual entry year and import type.
How Do You Map an Australian Classification to the U.S. HTS?
A practical process is:
-
Confirm the product specification.
Review:
• Description
• Material
• Function
• Dimensions
• Manufacturing method
• Technical data
-
Identify the Australian AHECC.
-
Use the international six-digit HS as a starting reference.
-
Search the current U.S. HTSUS.
-
Review additional measures such as:
• Section 232
• Section 301
• AD/CVD
• Applicable Chapter 99 provisions
-
Provide the complete product information to the U.S. importer or Licensed Customs Broker for final review.
Why Should You Not Guess an HS Code?
A supplier's existing code may simply be:
• A classification used in another country
• An old classification
• A code generated from a basic product description
• A code used on previous paperwork
It may not be suitable for U.S. import entry.
Complex products should be supported by information such as:
• Product photos
• Datasheets
• Material composition
• Intended use
• Technical drawings
• Manufacturing information
Who Is Responsible for the U.S. HTS Classification?
The U.S. Importer of Record has important responsibilities for the customs entry.
In practice, the importer may appoint a:
Licensed Customs Broker.
The Australian exporter should support this process by providing accurate:
• Product information
• Origin information
• Material composition
• Technical documents
• Australian classification references
Classification should ideally be aligned before the goods leave Australia.
What Is a Binding Ruling?
Where classification is complex, a business may seek a:
Binding Ruling
from U.S. Customs and Border Protection.
A prospective ruling can provide a formal CBP decision on matters such as tariff classification or origin for a specifically described future transaction.
Supporting information may include:
• Product description
• Photos
• Technical data
• Material composition
• End use
• Proposed classification
• Transaction information
This can provide greater certainty for businesses regularly importing the same product.
How Long Does a Binding Ruling Take?
For eligible eRuling requests handled by the National Commodity Specialist Division, CBP generally aims to issue rulings within approximately:
30 calendar days.
More complex matters referred to Headquarters can take longer.
Businesses planning significant recurring U.S. imports should therefore consider classification questions before commercial shipments begin.
How Can a Customs Broker Help?
A Licensed Customs Broker can assist with reviewing:
• HTSUS classification
• Country of origin
• AUSFTA eligibility
• Section 232
• Section 301
• AD/CVD
• Import permits
• CBP entry requirements
For high-value or recurring imports, the cost of repeated classification errors can significantly exceed the cost of obtaining specialist advice early.
Common HS and HTS Mistakes
Common problems include:
• Using an Australian eight-digit code as a U.S. code
• Classifying only by product name
• Ignoring material composition
• Confusing complete machinery with parts
• Incorrect country-of-origin assumptions
• Checking only the base duty rate
• Ignoring Section 232 or Section 301
• Failing to check AD/CVD
• Using outdated tariff information
U.S. tariff measures can change quickly, so historical duty rates should not automatically be used for current shipments.
What Should Australian Exporters Prepare?
Useful documents and information include:
• Commercial Invoice
• Packing List
• Product description
• Product function
• Material composition
• Datasheet
• Product photos
• Australian AHECC
• Suggested six-digit HS
• Country-of-origin information
• AUSFTA origin information where applicable
• U.S. importer and customs broker details
Better product information allows a more accurate assessment of:
Landed Cost.
