Pro Tips for Audit Preparedness
Maintain 5-Year Records
Keep all import documentation for at least 5 years from date of entry as required by 19 CFR 163.4
Document Classification Rationale
Keep records explaining why each HS code was chosen, including binding rulings if applicable
Support Valuation Claims
Maintain documentation for all valuation elements including assists, royalties, and related party adjustments
Obtain Binding Rulings
Request CBP binding rulings for complex classifications to protect against future disputes
Consider C-TPAT Certification
C-TPAT membership can reduce audit frequency and provides supply chain security benefits
Conduct Internal Audits
Regular self-audits help identify and correct issues before CBP discovers them
Common Mistakes to Avoid
Ignoring Transfer Pricing Adjustments
Related party transactions require special valuation treatment. Failure to adjust customs value can result in significant duty underpayments
Missing FTA Documentation
Claiming FTA preference without proper certificates of origin can result in retroactive duty bills and penalties
Inconsistent Classifications
Classifying the same product under different HS codes creates red flags and increases audit probability
Poor Record Keeping
Missing or disorganized records make audit defense difficult and can lead to adverse findings
Undervaluing Assists
Failing to include assists in customs value is a common audit finding that results in duty adjustments
Neglecting Prior Audit Findings
Not addressing previous audit issues increases scrutiny and demonstrates lack of reasonable care
