DDP should put import clearance, duties and taxes on the seller under the sales contract. But the three-letter term does not change Australian customs law, prove that anti-dumping duty was calculated correctly or erase the exposure of the entity named as owner or importer on the declaration.
For an Australian buyer, the practical answer is therefore: DDP can allocate the cost to the seller, but the quote alone does not prove the border liability has been handled.
That distinction is newly relevant for importers reviewing steel orders after Australia opened continuation inquiry 710 into existing measures on specified hollow structural sections.
What DDP actually promises
Under DDP—Delivered Duty Paid—Incoterms 2020, the seller delivers the goods at the named destination, cleared for import and ready for unloading. The seller is responsible for export, transit and import formalities and for the associated duties and taxes.
That is the maximum seller obligation among the Incoterms rules. It is also why the ICC cautions that a seller should use DDP carefully: the seller needs a practical and legally workable way to complete import clearance in the destination country.
The term should be written precisely, for example DDP [named warehouse address], Incoterms 2020. A vague “all-in DDP” message does not identify the delivery point, declaration structure, exclusions or remedy if the amount assessed at the border differs from the quotation.
For a broader comparison of the trade terms, see OPL's Incoterms guide for Australian importers.
What DDP does not do
Incoterms allocate responsibilities between the parties to a sale. They do not set Australian tariff rates, replace customs procedures, decide ownership or create an exemption from anti-dumping measures.
The Australian Border Force requires importers to self-assess whether the goods are subject to dumping or countervailing measures, lodge the declaration and pay the treatment applicable to the relevant exporter or country under the current Dumping Commodity Register.
If the goods, exporter or rate is wrong, the fact that the commercial invoice says DDP does not make the declaration correct. It determines who promised to bear the cost between buyer and seller; any statutory debt and any contractual recovery claim are separate questions.
The declared owner or importer matters
Under the Customs Act 1901, customs duty due on imported goods is a debt to the Commonwealth payable by the owner of the goods. A customs agent can also be treated as an owner for Customs Acts liability, but appointing an agent does not relieve the underlying owner.
That makes the proposed declaration structure essential. Before accepting a DDP quote, ask:
- Which entity will be named as owner or importer on the Australian import declaration?
- Which ABN or Customs Client Identifier will be used?
- Who appointed and instructed the licensed customs broker?
- Will the Australian buyer receive the import declaration and payment evidence?
A foreign supplier can establish a workable DDP import structure, but the buyer should not assume that happened merely because the quotation uses the term. If the Australian buyer is named as owner or importer, the seller's promise to reimburse or absorb duties remains a contractual protection—not a substitute for a correct declaration.
Why anti-dumping duty makes the gap more serious
Anti-dumping and countervailing duties are additional to ordinary customs duty and indirect taxes. ABF warns that they can exceed the value of the goods in some cases.
The current treatment may depend on:
- the precise goods description;
- the legal manufacturer and exporter;
- the exporting country;
- a named exporter-specific rate or an all-other-exporters treatment;
- a confidential benchmark or variable component;
- the transaction's export price; and
- the date the goods left the export country.
A supplier cannot establish those points by writing “duty included” on a quotation. The broker needs the correct product and entity evidence and must use the live register.
The product-specific companion, Importing Steel Tube from China? Inquiry 710 Raises the Anti-Dumping Stakes, explains how those checks apply to hollow structural sections.
Anti-dumping can also change the GST amount
ABF includes dumping and countervailing duty in the value used to calculate import GST. If anti-dumping duty is omitted or understated, the GST calculation can also be wrong.
The entity that pays GST at the border is not automatically the entity entitled to claim an input tax credit. The ATO's ruling on importations and creditable imports explains that entitlement depends on the actual importing arrangement, creditable purpose, GST registration and supporting records.
Australian businesses should not assume that GST buried inside a single DDP price is automatically recoverable. Confirm the proposed importer, records and tax treatment before using that amount in the landed-cost model.
Seven checks before accepting a DDP quotation
- Name the destination precisely. Use
DDP [exact place], Incoterms 2020, not an unexplained delivery promise. - Identify the declared owner or importer. Obtain the complete legal name, ABN or Customs Client Identifier before lodgement.
- Identify the broker and authority. Confirm who appointed the broker and who will approve the declaration data.
- Itemise the price. Separate ordinary customs duty, anti-dumping or countervailing duty or security, import GST, freight and clearance costs.
- Verify the goods and exporter. Match the exact product, manufacturer, exporter and supplier chain to the current register rather than relying on a generic HS code.
- Allocate later changes in writing. The contract should address securities, reassessments, penalties, refunds, document failures and the remedy if the seller cannot deliver cleared goods at the named place.
- Collect the border records. Retain the import declaration, payment evidence, commercial documents and proof of export date.
These checks do not replace a licensed customs broker, tax adviser or legal advice where the exposure is material. They make the proposed DDP structure visible before the buyer commits cash and production time.
Why inquiry 710 makes this timely
The Anti-Dumping Commission opened inquiry 710 on 3 August 2026 for specified hollow structural sections exported from China, Korea, Malaysia and Taiwan.
The inquiry did not create a universal new duty, but it puts existing measures and future treatment under active review. Importer questionnaire Parts B and C are due 24 August, Parts D and E on 31 August, and initial submissions on 9 September.
An importer using DDP for potentially in-scope steel should verify now who controls the declaration, which exporter treatment is being used, and what the contract says if the border result changes. The 4–9 August China-Australia import brief provides the wider weekly context.
Bottom line for Australian importers
DDP is a meaningful seller obligation, but it is not evidence of customs compliance and it does not make Australian statutory liability disappear.
Before accepting a DDP quotation where anti-dumping may apply, verify the declared importer, product scope, manufacturer and exporter, live register treatment, itemised duty and GST assumptions, and the documents you will receive after entry. Then make the sales contract state who bears any later assessment and what remedy applies if the seller's all-in promise fails.
