How to Prepare for an Australian Customs or ABF Post-Entry Audit

ABF usually gives ten working days to respond to an audit. Use this checklist to organise valuations, HS reasoning, and supporting documents. Spotyard Sourcing & Logistics handles ABF, DAFF, and GST compliance so you clear cargo without surprises.

Common Audit Triggers

  • Large swings in declared customs values between shipments
  • Frequent concession or duty refund claims
  • High-risk categories like apparel, footwear, and medical devices
  • Tip-offs from other agencies or overseas customs

Build an Audit-Ready Folder

  • Store every shipment's paperwork in clearly named folders (for example, YYYY-MM-DD_Supplier_PO)
  • Keep signed commercial invoices, packing lists, contracts, and proof of payment
  • Save HS classification notes or advance rulings for each SKU
  • Archive inspection photos to prove product identity if ABF questions the tariff

Responding to ABF

  1. Acknowledge the audit letter immediately and nominate a contact person.
  2. Provide complete document bundles rather than piecemeal replies.
  3. Log any verbal guidance from ABF officers in follow-up emails.
  4. Escalate valuation or tariff disputes early so you can negotiate realistic timelines.

If Issues Are Found

  • ABF can direct you to lodge amended import declarations and pay short-paid duty, GST, and penalties.
  • Voluntary disclosures usually reduce penalties when you flag errors first.
  • Update SOPs, HS coding guides, and broker instructions to prevent repeat findings.

Spotyard's compliance team runs pre-audit health checks so you know where gaps sit before ABF comes knocking.
