Certificates of Origin Explained

A certificate of origin (CO) declares where goods were produced. These documents unlock preferential tariff rates, satisfy regulatory requirements, and protect against anti-dumping duties. Understanding COs is essential for cost-effective international trade.

Types of Certificates

Non-Preferential COs

  • Indicate country of origin without FTA benefits
  • Required by many countries for customs
  • Issued by chambers of commerce
  • General trade compliance

Preferential COs

  • Claim benefits under free trade agreements
  • Reduce or eliminate duties
  • Specific requirements per agreement
  • Significant cost savings potential

Common Certificate Types

USMCA Certificate

  • US-Mexico-Canada Agreement
  • No specific form (certification statement)
  • 9 required data elements
  • Self-certified by importer, exporter, or producer
  • Blanket certification for 12 months allowed

EUR.1 Movement Certificate

  • EU preferential agreements
  • Authenticated by customs
  • Common in EU-partner country trade
  • Being replaced by REX system

Form A (GSP)

  • Generalized System of Preferences
  • For developing country exports
  • US GSP status varies
  • Required for preference claims

Form B (UK GSP)

  • UK's version of GSP
  • Post-Brexit requirement
  • Different form from EU

CAFTA-DR, KORUS, CPTPP

  • Specific agreement certificates
  • Each agreement has requirements
  • Many self-certification formats
  • Regional value content rules

Rules of Origin Principles

Wholly Obtained

  • Products entirely produced in country
  • Mineral products, agricultural goods
  • Natural resources
  • Simplest origin determination

Substantial Transformation

  • Products with non-originating materials
  • Transformation sufficient to change origin
  • Various tests apply
  • Country of origin becomes last substantial transformation

Tariff Shift Rule

  • Non-originating inputs must shift HS chapter/heading
  • Common in modern FTAs
  • Specific rules per product category
  • Easier to verify than value rules

Regional Value Content (RVC)

  • Percentage of value from region
  • Net cost method
  • Transaction value method
  • Varies by product and agreement

USMCA Specific Requirements

Automotive Rules

  • 75% RVC (up from 62.5%)
  • 40-45% Labor Value Content (LVC)
  • 70% steel and aluminum from North America
  • Specific high-wage requirements

Melt and Pour

  • Steel: Must be melted and poured in North America
  • Aluminum: Must be smelted and cast in North America
  • Prevents third-country transshipment
  • Verification requirements

Data Required on USMCA Certificate

  1. Importer, exporter, or producer certification
  2. Certifier name and contact
  3. Exporter name and address
  4. Producer name and address
  5. Importer name and address

  7. Origin criterion
  8. Blanket period (if applicable)
  9. Authorized signature and date
