ABF usually gives ten working days to respond to an audit. Use this checklist to organise valuations, HS reasoning, and supporting documents. Spotyard 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.
