Learning outcomes

  • Rebuild transaction value from commercial invoices and contracts
  • Identify assists, royalties, and proceeds that belong in the duty base
  • Allocate freight and insurance without distorting landed cost
  • Design a sampling plan that a financial auditing app can automate later
  • Draft findings with clear criteria, condition, cause, and effect
  • Separate customs corrections from GL timing differences
  • Prepare working papers that survive second-level review
  • Know when to escalate for legal or broker interpretation

Modules

  1. 01

    Customs file anatomy

    Declarations, broker packets, and the evidence finance actually needs versus what typically arrives.

  2. 02

    Transaction value reconstruction

    Invoice to payment reconciliation, related-party indicators, and incomplete commercial docs.

  3. 03

    Assists and royalties

    Tooling, materials, design fees, and license streams — what enters the duty base and what stays in the P&L only.

  4. 04

    Freight, insurance, and inland legs

    Allocation methods that keep import cost audits reproducible across shipment mixes.

  5. 05

    Exception design for audit apps

    Thresholds, severity tags, and false-positive control so queues stay usable.

  6. 06

    Mini-audit and findings lab

    Capstone review of a redacted file set with peer critique and instructor sign-off criteria.

Portrait of instructor Helen Cho

Helen Cho

Former trade controller · 14 years across electronics and industrial imports

Helen designs the studio’s file sets from patterns observed in Taiwan(China) import corridors. She coaches judgment calls rather than reciting tariff tables, and she is frank when a scenario needs counsel beyond training.

FAQ

Do you teach a specific financial auditing app brand?

No. We teach review loops — sampling, exception severity, and workpaper structure — that transfer into common app queues. Vendor configuration is your IT team’s job.

Will this replace advice from our customs broker or counsel?

It will not. A real limitation of the studio is that we do not provide legal opinions or binding classification advice. We train you to ask better questions and document what you decided.

How much time should I reserve each week?

Plan five to seven hours across live sessions and file work. Module four often runs long if your broker files are fragmented.

Can we use our own import data?

Yes for Bonded Desk and by arrangement in Harbor Cohort. Files must be redacted before upload; we provide a checklist.

“Helen’s royalty walkthrough caught an assist we had booked only as opex for two years.”

“Solid studio. The app module is thinner than the valuation modules — fine if you already have IT support.”
