Importing from China to Australia: Duties and Biosecurity

Importing from China to Australia comes down to three cost layers and two clearance gates. The cost layers are customs duty (usually 5%, but often zero under the China-Australia Free Trade Agreement), 10% GST calculated on the goods value plus duty, freight and insurance, and clearance fees. The gates are an Import Declaration lodged with the Australian Border Force for consignments valued over AUD 1,000, and biosecurity clearance from the Department of Agriculture, Fisheries and Forestry (DAFF), which inspects timber packaging and container cleanliness with unusual seriousness. China is Australia's largest source of imported goods, so the route is well-trodden, yet the details still catch first-time importers out.

Get the paperwork right and a routine sea-freight consignment clears within days of the vessel berthing. Get it wrong, the wrong tariff classification, untreated wooden pallets, a missing packing declaration, and your container sits at the terminal while storage and inspection charges accumulate daily.

This guide covers the full process: landed-cost math, how the ChAFTA duty discount works in practice, the documents customs expects, why quarantine stops so many China shipments, the product standards your goods must meet, and when a customs broker earns its fee. If you are still choosing suppliers, a sourcing agent that verifies factories before you commit to a container is usually the cheapest risk control available.

What does it actually cost to import from China to Australia?

For most manufactured goods, landed cost stacks from five components: the supplier price, international freight and insurance, customs duty, GST, and clearance charges. Duty is a percentage of the customs value (the price paid, converted to Australian dollars at the exchange rate on the date of export). GST is 10% of the "taxable importation": the customs value plus any duty plus transport and insurance to Australia. Note the compounding: you pay GST on the duty too.

Cost component · Without ChAFTA (5% duty) · With ChAFTA COO (0% duty)

• Customs value: AUD 10,000 · AUD 10,000
• Sea freight + insurance: AUD 1,500 · AUD 1,500
• Customs duty: AUD 500 · AUD 0
• GST (10% of value + duty + freight): AUD 1,200 · AUD 1,150
• Import processing charge (electronic): ~AUD 50 · ~AUD 50
• **Government charges total: AUD 1,750 · AUD 1,200**

One certificate saves AUD 550 on a AUD 10,000 shipment here, and the saving scales with consignment value. GST-registered businesses claim the GST back as an input tax credit on their Business Activity Statement, turning the 10% into a cash-flow timing cost. If you are not GST-registered, the GST is a permanent cost in your landed price.

Two costs new importers miss. First, anti-dumping duties: Australia applies extra duties to specific Chinese products (certain steel goods, aluminium extrusions and others) on top of standard duty, and they can be large, so check for a dumping duty notice on your product before pricing anything. Second, alcohol and tobacco are taxed at far higher rates under separate rules this guide does not cover.

How does the ChAFTA duty discount actually work?

The China-Australia Free Trade Agreement has been in force since 20 December 2015, and DFAT reports that over 95% of Australian tariff lines on Chinese imports now carry zero duty. But the discount is not automatic. Buying from a Chinese supplier alone gets you nothing. To claim the preferential rate you need a valid Certificate of Origin (COO) issued by an authorised body in China, and your broker must declare it at import. No certificate, no discount: you pay the general rate of 5% for most manufactured goods.

Practical points worth knowing. One certificate per shipment: a COO can cover up to 20 line items and is valid for one year, but every consignment needs its own. Small shipments skip the paperwork: DFAT confirms no COO is required where customs value is below AUD 1,000. Retrospective claims are allowed: if goods arrived without a COO, you can seek a refund of excess duty, up to 12 months from the date of shipment with a retrospective certificate, up to 4 years where one was held at import. Goods must genuinely originate: goods merely transhipped through China do not qualify, and customs can verify certificates with the issuing body.

Build the COO into your supplier agreement from the first order. Ask before paying a deposit whether the supplier can arrange one and what it costs. Suppliers in the major export regions do this routinely; one that has never heard of it is a useful early warning sign.

What documents does Australian customs require?

Clearance runs on documents, and mismatches between them cause a large share of delays. Assemble the full set before the goods ship:

Document · Purpose · Provided by

• Commercial invoice: Itemised value, quantities, Incoterms, HS codes · Supplier
• Packing list: Cartons, weights, dimensions · Supplier
• Bill of lading / air waybill: Contract of carriage · Forwarder / carrier
• Packing declaration: Packaging materials used (timber or not) · Supplier or forwarder
• Fumigation / heat treatment certificate: Proof of ISPM 15 timber treatment · Treatment provider
• Certificate of Origin (ChAFTA): Proof of originating status · Authorised body in China
• Import permits: For regulated goods only · Importer, in advance

The packing declaration is a biosecurity document, not a formality: DAFF uses it to decide whether your container gets a timber inspection. A missing or vague declaration almost guarantees one. The commercial invoice sets your customs value, and undervaluing goods to cut duty is illegal, easy to detect on audit, and can lead to seizure and penalties. Keep every import document for five years; the Border Force requires it and post-clearance audits happen.

How do you lodge an Import Declaration?

Consignments over AUD 1,000 entering for home consumption need a Nature 10 (N10) Import Declaration, lodged electronically through the Border Force's Integrated Cargo System (ICS). Shipments at or below AUD 1,000 generally clear under a simplified Self-Assessed Clearance handled by the courier. Goods bound for a licensed warehouse use a Nature 20 (N20) declaration instead, with duty and GST deferred until withdrawal.

Almost no first-time importer lodges an N10 alone. The standard route is a licensed customs broker, who files through the ICS using your documents. You remain legally responsible for the declaration's accuracy, so read the draft before lodgement, especially the tariff classification and declared value.

On cost and timing: the ABF charges an import processing fee per declaration that rises with customs value and is cheaper electronically, roughly AUD 50 for consignments between AUD 1,000 and 10,000, rising to around AUD 152 above AUD 10,000 (rates are indexed, so confirm current figures). Your broker's service fee and terminal handling sit on top. Once charges are paid and biosecurity intervention complete, the ABF issues an Authority to Deal releasing the goods. A clean sea-freight consignment typically clears within a few working days of berthing; air freight often clears same-day.

Why does quarantine stop so many shipments from China?

Australia's biosecurity regime is among the world's strictest, and China-origin cargo gets close attention. DAFF decides whether your goods, packaging and container may enter. Three issues cause most holds.

Timber packaging. Solid-wood pallets, crates, skids and dunnage must comply with ISPM 15: heat-treated (minimum 56°C core temperature for 30 minutes, marked HT) or fumigated with methyl bromide (marked MB) by a certified provider, bearing the IPPC mark with treatment code and certification number. Plywood, particle board, OSB and veneer are exempt, as is wood 6 mm or thinner. Non-compliant timber is ordered for treatment, re-export or destruction at your expense. Ask your supplier for ISPM 15-stamped pallets and confirm it in the packing declaration.

Container cleanliness. DAFF orders inspections where the container exterior shows soil or plant contamination, or the packing declaration is missing or vague. Used machinery and anything with soil contact faces the heaviest scrutiny and must arrive clean.

Brown marmorated stink bug (BMSB) season. From 1 September to 30 April, DAFF runs seasonal BMSB measures and China is a target-risk country. Certain high-risk sea-freight goods must be treated offshore before arrival; LCL containers are managed at container level. Air freight faces random inspections rather than mandatory treatment. If you import machinery or goods with hollow components, check the current season's target list on DAFF's website before booking, as requirements update annually.

For regulated goods (food, plants, animal products, chemicals), check DAFF's BICON database for exact import conditions first. Some need a permit arranged before the goods leave China; no broker can fix a missing permit after arrival.

What product standards must your goods meet?

As the importer you are legally the supplier of the goods in Australia, which makes you responsible for product compliance. Penalties include seizure, mandatory recalls and fines.

Electrical safety: the RCM mark. Electrical equipment must carry the Regulatory Compliance Mark, mandatory since 1 March 2016. The single mark covers two regimes: electrical safety (ERAC, under the Electrical Equipment Safety System) and electromagnetic compatibility/telecoms (ACMA). Equipment is risk-classified into three levels: Level 3 (high risk) needs a Certificate of Conformity; Levels 1 and 2 need a Certificate of Suitability. The Responsible Supplier who registers equipment on the ERAC national database must be an Australian or New Zealand entity with an ABN. A Chinese factory cannot fill that role. If you import anything that plugs in, charges, or has a motor or heating element, arrange RCM compliance before ordering: it needs accredited test reports and a local entity holding the registration.

ACCC product safety. The ACCC enforces mandatory safety standards and permanent bans across categories from children's toys to treadmills. If your product falls under a mandatory standard it must comply regardless of the factory's Chinese certifications. Check Product Safety Australia for your category before committing to production, and consider pre-shipment quality control with compliance checkpoints, not just cosmetic inspection.

Labelling. Food has mandatory country-of-origin labelling; cosmetics and chemicals have ingredient rules; textiles need fibre content and care labels. Labelling failures are a common cause of detained goods: cheap to prevent, expensive to fix after landing.

Which Australian port should you ship through?

Container trade flows through three main gateways: Sydney (Port Botany), Melbourne and Brisbane, with smaller volumes via Fremantle and Adelaide. The rule is simple: ship to the port nearest where goods will be stored or sold, because Australian domestic freight is expensive relative to the ocean leg. A container landed in the wrong city can cost more to move interstate than it cost to cross the Pacific.

Port · Best for

• Sydney (Port Botany): Goods sold or warehoused in NSW
• Melbourne: Victoria, SA and Tasmania distribution; busiest container port
• Brisbane: Queensland distribution
• Fremantle (Perth): Western Australia; avoids the long interstate leg

For LCL shipments, check which ports your forwarder consolidates through; routing via their main consolidation port is usually faster and cheaper than forcing a direct service. Ocean transit from major Chinese ports to the east coast is measured in weeks, air freight in days, so build the sea transit into inventory planning and hold safety stock.

Do you need a customs broker?

Not legally, but for commercial cargo over AUD 1,000 going without one is a false economy. A licensed broker classifies your goods under the correct tariff code, claims your ChAFTA preference, flags permit requirements before shipment, handles DAFF queries, and arranges port handling and delivery. A wrong classification found on audit means back-paid duty plus penalties; the broker's fee is a fraction of that risk.

Choose a broker with experience in your product category and China-origin cargo, since biosecurity familiarity matters more than most importers expect. Ask how they handle DAFF inspections and what the all-in fee covers: brokerage, ABF charges, terminal handling and delivery are often quoted separately. Many forwarders offer in-house brokerage, so one party owns the cargo from the Chinese port to your warehouse. A logistics partner managing freight and clearance together removes most handoff risk. For small or infrequent imports under AUD 1,000, the courier's standard clearance service is usually enough.

Frequently asked questions

Do I pay duty and GST on samples from China?

It depends on value. Samples at or below AUD 1,000 generally clear under Self-Assessed Clearance with no duty or GST at import, except tobacco and alcohol. Samples over AUD 1,000 need a full Import Declaration and attract duty and GST like any commercial import. Do not declare saleable stock as samples to avoid duty; that is a customs offence.

Can I claim back the GST paid on imports?

Yes, if your business is GST-registered. Import GST is claimed as an input tax credit on your Business Activity Statement for the period the goods clear. You need an ABN and GST registration, and you must keep the import declaration as evidence. Below the registration threshold the 10% is a permanent cost, so time a first large import for just after registering if you are near the threshold.

What if my supplier cannot provide a ChAFTA Certificate of Origin?

Three options: ask whether a trading company in their chain can arrange one; pay the general duty rate (usually 5%) and absorb it; or switch to a supplier that can, since established exporters arrange COOs routinely and inability to do so can signal a middleman. You can also claim the preference retrospectively, up to 12 months from shipment with a retrospective certificate.

How long does customs clearance take?

A clean consignment clears fast: air freight often same-day, sea freight within a few working days of berthing. Biosecurity intervention adds time, from days for a document check to weeks for ordered fumigation and re-inspection. Build buffer stock into your planning, especially during BMSB season (September to April) when inspections spike.

What happens if goods fail a biosecurity inspection?

DAFF directs treatment, cleaning, re-export or destruction, at your expense. Treatment and re-inspection fees plus accumulating terminal storage can exceed the value of a small consignment. Prevention is far cheaper: ISPM 15-compliant packaging, an accurate packing declaration, and clean goods.

Your pre-shipment decision rule: five checks before the container leaves China

Most import problems are decided before the goods ship. Run these checks while you still have leverage over the supplier. First, origin paperwork: can the supplier provide a ChAFTA Certificate of Origin, and if not, is the 5% duty in your margins? Second, classification: has your broker confirmed the HS code and checked for anti-dumping duties? Third, biosecurity: is all timber packaging ISPM 15-stamped with an accurate packing declaration? Fourth, compliance: is RCM arranged with a local Responsible Supplier for electrical goods, and have you checked ACCC mandatory standards for your category? Fifth, permits: does BICON show any import permit requirement, and is it in hand?

If any answer is no, delay the shipment, not the business. A week in China costs a fraction of a detained container in Sydney. For official detail, DFAT's guide to using ChAFTA covers origin claims and retrospective refunds, and DAFF's timber packaging requirements spell out exactly what pallets and crates must carry.
