Ako vypočítať Tariff Engineering Savings

Čo je Tariff Engineering Savings?

The Tariff Engineering Calculator estimates potential duty savings from legally reclassifying products through design modifications, component changes, or import sequencing to qualify for a lower HTS tariff classification.

Vzorec

Savings = Annual Import Value × (Current Duty Rate - Engineered Duty Rate) - Engineering Cost
V
Annual Import Value ($) — Total annual value of imports being reclassified
R₁
Current Duty Rate (%) — Existing HTS duty rate before engineering
R₂
Engineered Rate (%) — Target duty rate after product modification
EC
Engineering Cost ($) — One-time cost of design modification and legal review

Sprievodca krok za krokom

  1. 1Identify the current HTS classification and duty rate for your product
  2. 2Research alternative classifications with lower duty rates that could apply with modifications
  3. 3Calculate the cost of product modifications needed to qualify for the lower classification
  4. 4Compare annual duty savings against one-time engineering and qualification costs

Worked Examples

Vstup
Footwear classified at 37.5% duty, modify outer sole to qualify at 8.5%, $2M annual imports, $50K modification cost
Výsledok
Annual savings = $2M × (0.375 - 0.085) = $580,000. Payback = $50K / $580K = 1 month
Vstup
Apparel import at 16%, add enough weight in non-textile to classify as "other" at 3%, $5M imports
Výsledok
Annual savings = $5M × 0.13 = $650,000

Common Mistakes to Avoid

  • Making superficial changes that customs authorities will see through as sham reclassification
  • Not obtaining a binding ruling from CBP before committing to the product modification
  • Ignoring the risk of retroactive reclassification if CBP later disagrees with your classification

Frequently Asked Questions

Is tariff engineering legal?

Yes, tariff engineering through genuine product modifications is entirely legal. CBP and courts have upheld that importers have the right to design products to minimize duty, as long as the classification is accurate for the actual product imported.

What is a binding ruling and why should I get one?

A binding ruling is an official CBP decision on the classification of your product. It provides legal certainty and protection against retroactive reclassification. Apply through the CBP eRulings system before making product changes.
