Import Declaration Explained

An Import Declaration is the record made with the Australian Border Force describing a shipment as it enters Australia. It captures the customs details of the goods, the party bringing them in, and the tariff and value information used to assess duty and GST.

Many Australian businesses never prepare this document themselves. It is commonly lodged by a customs broker or a carrier clearance team on the importer's behalf. Some businesses do lodge their own declarations, but for most ecommerce founders the Import Declaration is prepared by someone else and shared back afterwards.

You can think of the Import Declaration as the official summary of your shipment from a customs perspective. The Commercial Invoice, Packing List and Certificate of Origin are the underlying evidence. The Import Declaration is the record that pulls those inputs together for the border process.

An Import Declaration commonly records information such as:

• tariff classification for the goods,
• customs value used for duty assessment,
• country of origin claimed for the shipment,
• duty assessed on the shipment,
• GST assessed on the shipment, and
• importer details for the business receiving the goods.

Because it draws these details together, the Import Declaration becomes an important reference when reviewing shipment costs. If a duty or GST amount looks unexpected, or a landed cost calculation does not reconcile, the declaration is often one of the first documents worth looking at.

MarginMining does not provide customs, tax or legal advice. This guide is educational and is intended to help you understand the document before you review your own shipment evidence.

When you upload a shipment for an Import Cost Review, MarginMining may compare the Import Declaration against your Commercial Invoice, Packing List, Certificate of Origin, HS codes, freight documentation and supplier information. The review looks for consistency, completeness and clarity, not compliance.

• Tariff classification against the Commercial Invoice and any supplier or product references
• Customs value against the Commercial Invoice total and freight documentation
• Country of origin against the Certificate of Origin and other shipment paperwork
• Shipment references, container or consignment numbers across documents
• Importer details against the business you would expect to see recorded
• Duty and GST amounts alongside supporting evidence for context
• Gaps or inconsistencies against the invoice, packing, origin and clearance evidence

MarginMining highlights inconsistencies, review opportunities and missing evidence rather than determining whether an Import Declaration is correct. Anything the review surfaces is a prompt to look again, not a conclusion.

Examples of the kinds of gaps a review may surface:

• The tariff classification recorded differs from the description on the Commercial Invoice.
• The customs value differs from the invoice total without a clear explanation.
• Origin evidence is missing or does not match the country recorded on the declaration.
• Shipment references or consignment numbers do not line up across documents.
• Importer details on the declaration differ from the business you would expect.
• The Import Declaration has not been shared for review and no copy is available.

Each of these is a reason to look again at the shipment evidence, or to raise a question with your customs broker or carrier clearance team, before the numbers are trusted downstream.

Reviewing an Import Declaration alongside the Commercial Invoice, Packing List and any origin evidence can help identify discrepancies before they become recurring process issues. When the declaration, the invoice and the supporting documents all describe the same shipment in the same way, the story of that shipment is easy to follow.

Reconciliation is best treated as good operational practice rather than an assumption that anything is wrong. Differences between documents may simply need a short clarification with your supplier or carrier clearance provider. Even so, catching them early tends to be easier than untangling them later.

• Who prepares an Import Declaration?

  It is commonly lodged with the Australian Border Force by a customs broker or a carrier clearance team on behalf of the importer, though some businesses lodge their own declarations. The Import Declaration is not usually something a founder prepares themselves.

• Can I obtain a copy after my shipment clears?

  In most cases you can request a copy from whoever lodged the declaration on your behalf, such as your customs broker or carrier clearance provider. Keeping a copy alongside your other shipment evidence makes later review much easier.

• Does every shipment have one?

  Not every shipment. Requirements depend on the shipment type, value and how it enters Australia. Low-value shipments and some courier consignments may be handled differently. If you are unsure, your carrier clearance provider or customs broker can confirm what applies to your shipment.

• Is an Import Declaration the same as a customs invoice?

  No. A Commercial Invoice records the sale of the goods between supplier and buyer. An Import Declaration is the record made with the Australian Border Force describing the shipment for customs purposes. The two documents reference each other but are prepared separately.
