Overpayment of duties and lost preferential tariff benefits from conservative or incorrect classification
Definition
To avoid penalties, many traders classify goods under overly high‑duty headings or fail to link documentation and HS codes to trade‑agreement preferences, leading to chronic overpayment of customs duties. Because the customs function is often siloed from pricing and margin analytics, these leakages remain invisible and unbilled back to customers or suppliers.
Key Findings
- Financial Impact: Ongoing duty overpayments of 2–4 percentage points of customs value on affected product lines; industry practitioners report that correct classification and preference use routinely avoid six‑figure annual duty costs for mid‑sized import programs.[5][1][2]
- Frequency: Daily with each customs declaration on imports/exports and monthly with duty settlements
- Root Cause: Lack of detailed product data and classification expertise causes companies to use generic or catch‑all codes and to overlook HS notes and exceptions that would put goods in lower‑duty or preferential categories.[1][5] Weak integration between customs documentation, origin documentation, and trade‑agreement rules means that even when products qualify for preferential rates, the evidence is not assembled or declared correctly.[2][5]

Financial Impact
$100,000–$1,000,000+ per large infrastructure project (depending on equipment import volume); multiplied across portfolio of active projects • $100,000–$300,000 annually hidden in gross margin variance (2–4% of $5–15M annual customs spend for multinational; plus lost refund opportunity) • $100K–$1M+ per project depending on import scale (2–4% duty overpayment on imported capex; multiplied by years of project operation if recurring spare-parts imports also misclassified)
Current Workarounds
Ad-hoc tariff classification requests to logistics partners; manual country-of-origin verification via purchase order review; incomplete duty drawback claim filing (leaving money on the table); siloed commodity teams without shared tariff intelligence • Commodity trading house uses senior coordinator's tacit knowledge of 'safe' codes; parallel Excel models with manual tariff rate updates; spot-checks by compliance team (post-shipment) • Conservative HTS code selection via manual lookup tables or industry memory; Excel-based tariff rate tracking without preference linking; email chains with customs brokers
