How to Read a Disposable Glove Certificate of Conformity (CoC)

Jul 22, 2026

A Certificate of Conformity (CoC) is a document issued by a manufacturer or notified body confirming that a product meets specified regulatory and technical requirements. For disposable gloves, the CoC is the fastest way to verify that a batch meets the claims made on the box.

1. What a CoC Is - and What It Is Not

A CoC is an attestation of compliance. It is not a test report, not an invoice, and not a marketing brochure. It should reference the exact standard, batch or lot number, and the issuing authority. If the CoC does not match the product label, the document is unreliable.

2. Eight Fields to Check on Every Glove CoC

Field	What to Look For	Why It Matters
Product description	Exact glove type, material, powder-free status, size range	Ensures the CoC covers the SKU you are buying
Applicable standards	EN 455, EN 374, ASTM D6319, ASTM D3578, ISO 11193	Confirms regulatory scope for your market
Notified body / lab	Name, address, accreditation (ISO 17025)	Unaccredited labs produce unenforceable certificates
Test report numbers	Unique report IDs with dates	Lets you cross-check with the lab
Batch / lot number	Must match the shipment label	Traceability and recall management
AQL level	AQL 1.5, 0.65, 2.5, 4.0	Determines defect allowance and medical-grade status
Expiry / validity	CoC issue date and validity period	Old CoCs may not reflect current formulation
Authorized signature	Signed by quality manager or regulatory representative	Demonstrates accountability

3. Red Flags That Should Stop the Order

The CoC has no test report number or the lab is not ISO 17025 accredited.
The standard referenced is outdated, vague, or incorrect for the product.
The batch number on the CoC does not match the physical carton label.
The document is a generic template with no product-specific details.
The manufacturer refuses to share the original test report or factory quality manual.

4. How to Verify the CoC

Contact the test lab directly using contact details from its official website, not from the CoC itself. Provide the report number and ask for confirmation. For EU CE-marked medical gloves, check the notified body identification number in the NANDO database. For GSO-marked products, verify the registration in the GCC Standardization Organization systems or national authority portals.

5. FAQ

Q: Is a CoC the same as a test report?

A: No. A CoC is a declaration that the product complies with standards. A test report contains the actual measurement data from a lab.

Q: Who can issue a CoC for disposable gloves?

A: A manufacturer can issue a self-declaration for some standards, but medical-grade and PPE claims usually require a notified body or ISO 17025 lab.

Q: How long is a CoC valid?

A: There is no universal expiry, but most buyers accept CoCs issued within 1-2 years. A new formulation, standard update, or material change requires a new CoC.

Q: What does AQL 1.5 on a CoC mean?

A: AQL 1.5 means the accepted quality level allows up to 1.5% defective gloves in the sampled lot. Lower AQL values mean stricter quality.

Q: Can I use a CoC from one country in another market?

A: Not automatically. A CoC must reference the standards recognized in the target market. For example, EN 455 is for the EU; ASTM D6319 is for the US market.
