What Are CO and CQ? Why Crucial in International Trade? (Updated 2025)
In import-export operations, CO (Certificate of Origin) and CQ (Certificate of Quality) are two essential documents verifying the origin and quality of goods. These certificates not only help businesses comply with customs regulations but also enable preferential tariff treatment and build trust with global customers.
What is CO?
What is CO?
CO – Certificate of Origin is an official document issued by competent authorities in the exporting country to certify that the goods are produced, processed, or manufactured in that country.
CO is critical for:

- Meeting import regulations of destination countries
- Preventing counterfeit or smuggled goods in global supply chains
Key contents of a CO include:
- Exporter and importer names and addresses
- Product description and specifications
- Quantity, weight, and value
- Country of origin

What is CQ?
What is CQ?
CQ – Certificate of Quality is issued by the manufacturer to confirm that the product meets the technical standards of the production country or international standards.
CQ is commonly required for industries with high-quality standards such as electrical equipment, machinery, construction materials, and medical devices.
Key contents of a CQ include:
- Manufacturer information (name, address, registration number)
- Importer details (company name and address)
- Product name, HS code, quantity, weight
- Shipment date and location
- Manufacturer’s confirmation (signature, stamp, logo)
What Makes a CO or CQ Valid?
To be legally accepted, a CO or CQ must:
- Be issued using the correct format (e.g., Form D, E, AANZ, etc.)
- Come from an authorized organization (e.g., Ministry of Industry and Trade or its delegates)
- Include valid signatures, stamps, and no erasures or false information
- Be written in English or bilingual, depending on the destination country’s customs requirements
Common CO Types in International Trade
| CO Type | Applicable Markets |
| CO Form A | Goods exported from developing to developed countries (e.g., EU, USA) |
| CO Form D | Intra-ASEAN trade to enjoy tariff preferences |
| CO Form E | ASEAN-China FTA (ACFTA) |
| CO Form S | Vietnam–Laos trade |
| CO Form AI | ASEAN–India Free Trade Agreement (AIFTA) |
| CO Form AANZ | ASEAN–Australia–New Zealand FTA (AANZFTA) |
| CO Form VC | Vietnam–Chile Free Trade Agreement |
Correct CO classification helps businesses reduce import duties, validate documents, and strengthen competitive advantage.
Legal Framework for CO and CQ in Vietnam
- Law on Standards and Technical Regulations (2006)
- Decrees 127/2007/ND-CP & 67/2009/ND-CP on Rules of Origin
- Decision 24/2007/QD-BKHCN on Conformity Certification
Why Are CO and CQ Important for Your Shipments?
CO (Certificate of Origin)
- Confirms product origin — a prerequisite for tariff exemptions and overcoming trade barriers
CQ (Certificate of Quality)
- Proves the goods meet required quality standards, especially for bidding and international sales
Both CO and CQ are essential in customs clearance, regulatory compliance, and quality inspection during import-export procedures.
