If you are sourcing stamped or fabricated metal components from overseas and shipping them into Australia, one of the first things you will need to get right is the correct hs code for sheet metal parts. Getting the classification wrong can mean paying the wrong amount of duty, holding your shipment at the border, or even facing a penalty. This guide explains how sheet metal parts are classified under the Australian Customs Tariff, what duty and GST you can expect, and how buying from a factory that understands export documentation can make the whole process smoother.
Which HS heading covers sheet metal parts?
In the Harmonized System, most ready-made sheet metal parts fall under Chapter 73 (articles of iron or steel) if they are steel, or Chapter 76 if they are aluminium. The most common heading for stamped and fabricated parts is HS 7326, "Other articles of iron or steel". If your component has been forged or stamped but not further worked, the statistical code 7326.1 attracts a 0% general duty rate in Australia. Parts that have been further worked, such as those used as components in passenger motor vehicles (7326.90.10) or other finished articles (7326.90.90), generally sit at a 5% general rate.
Very often the same physical part can be classified in more than one possible way, so it is worth confirming the description and statistical code with a customs broker before you book shipping. The classification also depends on the material, the degree of finishing, and the end use. For example, springs fall under 7320, while sheet metal structural frames sit under 7308 rather than 7326.
Duty, GST and additional charges you should budget for
On top of the tariff duty, Australia applies a 10% Goods and Services Tax (GST) on the customs value of the goods plus the duty. Importers also need to plan for the Import Processing Charge, which ranges from about AUD 50 to AUD 192 depending on the shipment value, and a biosecurity levy of roughly AUD 46 to AUD 74 where it applies. Goods cleared with a value under about AUD 1,000 may qualify for the Low Value Imported Goods threshold, which reduces the paperwork burden.
The good news for buyers sourcing from China is that the China-Australia Free Trade Agreement (ChAFTA) has reduced the duty on most Chapter 73 steel products to 0% when the correct certificate of origin is provided. Under ChAFTA you claim the preferential rate with a valid Form E certificate of origin, so it is worth asking your supplier to supply one. The Regional Comprehensive Economic Partnership (RCEP) also offers staged reductions for qualifying origins.
Compliance checks and anti-dumping awareness
Australia has active anti-dumping and countervailing measures on a range of steel products coming from China, Korea, Taiwan and Malaysia. Because these measures can change without notice and the duty rates can be substantial, it is important to check the Australian Border Force's Anti-Dumping Commission register before every shipment. Supplying a mill certificate tied to the actual heat or batch number of your steel helps confirm the chemical composition and mechanical properties, and it is a document that customs and building inspectors increasingly ask to see.
You should also keep your commercial invoice accurate, describing the product clearly, and include the country of origin and steel grade. Wooden crating or dunnage used to protect the parts must be ISPM 15 heat-treated or fumigated to meet the DAFF biosecurity requirements, otherwise your cargo can be held at the port.
Working with a factory that makes the paperwork easier
Choosing the right supplier affects more than unit price. A sheet metal parts supplier that operates its own factory rather than acting as a trading company can provide the technical documentation, material certificates and export paperwork that make customs clearance in Australia far more predictable. When you work directly with a stamping die manufacturer, you also remove the layers of middlemen that drive up cost and lengthen lead times.
DIAN STAMPING, established in 2003 in Zhejiang, China, is a factory-based manufacturer with more than 20 years of experience in automotive stamping dies, sheet metal parts, checking fixtures and welding jigs. The company operates a facility of around 50,000 m², employs roughly 110 people including close to 35 die designers and technicians, and produces about 2,000 sets of medium and small stamping dies each year. It supplies OEM customers including KIA, BYD, Toyota, Honda, Suzuki and Geely, and exports to more than 10 countries.
Customization, samples and delivery timelines
Because the exact HS code depends on the final part details, it helps to work with a manufacturer that can build the component to your specification from 2D drawings, 3D data or physical samples. Prototype services are available so you can validate the part before committing to high-volume production. The quality management system at DIAN STAMPING is certified to ISO 9001, with manufacturing practices aligned to IATF 16949-oriented automotive quality standards.
As a china sheet metal parts factory, DIAN offers free metal samples with freight paid by the customer, and typical delivery is 30 to 40 days for steel stamping dies and around 70 days for casting stamping dies, subject to the project scope. Stamping capability covers progressive dies, transfer dies and tandem multi-station dies, processing multiphase steel, aluminium, custom rolled and welded plate, and stainless steel for body-in-white, door, seating, instrument panel, fuel-tank, exhaust and chassis systems.
Final checklist before you import
To summarise, before shipping a consignment of sheet metal parts into Australia, confirm the correct HS classification (usually Chapter 73 or 76), check the general duty rate and whether a preferential rate applies under ChAFTA or RCEP, budget for GST and import processing charges, and verify there is no active anti-dumping measure on your product. Then choose a factory that can supply accurate certificates of origin, material mill certificates, clean packing compliant with Australian biosecurity rules, and clear commercial documentation. With the right HS code and the right partner, importing sheet metal parts to Australia can be a straightforward and cost-effective process.
