When sourcing reusable industrial gloves, a buyer should not rely only on a CE logo or a statement that a glove is “chemical resistant.”
For Category III personal protective equipment (PPE) intended for the EU market, buyers need to verify the glove model, the applicable EU type-examination certificate, the relevant technical markings and the additional conformity assessment procedure required by Regulation (EU) 2016/425.
This guide explains the main checks using Jiali JNI reusable green nitrile industrial gloves as a practical product example.
What Does CE Category III Mean for Protective Gloves?
Category III PPE covers certain risks that may cause very serious consequences, including death or irreversible damage to health.
Under Regulation (EU) 2016/425, Category III conformity assessment includes:
- Module B: EU type-examination by a notified body.
- Module C2 or Module D: An additional procedure covering conformity to type under the applicable production-supervision system.
A Module B certificate is therefore an important document, but buyers should not assume that Module B alone completes all Category III requirements.
For the legal requirements, see Regulation (EU) 2016/425 on EUR-Lex.
Step 1: Check the Certificate Against the Exact Glove Model
Start with the product identity rather than the certificate logo.
Confirm:
- Manufacturer’s legal name
- Glove model or product reference
- Material and construction
- Certificate number
- Notified body
- Issue and expiry information
- Applicable standards and certificate scope
Jiali manufactures the JNI series of reusable green nitrile industrial gloves in Zhanjiang, Guangdong, China.
Its published EU type-examination documentation identifies the following:
| Item | Jiali JNI Reference |
|---|---|
| Manufacturer | Zhanjiang Jiali Glove Products Co., Ltd. |
| Glove series | JNI |
| Material | Synthetic nitrile rubber |
| Color | Green |
| Notified body | CTC, No. 0075 |
| EU type-examination certificate | 0075/2236/162/02/25/0282 |
| Certificate expiry stated in document | February 11, 2030 |
| PPE category | Category III |
| Type-examination procedure | Module B |
The certificate applies to its documented product scope. It must not be presented as certification of every industrial, household or disposable glove manufactured by Jiali.
Buyers should request the applicable certificate and verify the exact model and current status before relying on the documentation.
Step 2: Understand EN ISO 374-1 Type A
EN ISO 374-1 concerns protective gloves against dangerous chemicals.
Type A indicates that the glove achieved the specified permeation performance against at least six defined test chemicals under standardized laboratory conditions.
The JNI certificate documentation identifies:
EN ISO 374-1: Type A — JKLMOPT
These letters identify the chemicals for which the documented test performance applies. They are not a blanket guarantee against all chemicals or mixtures.
When selecting industrial gloves, buyers should assess:
- Exact chemical name and concentration
- Expected contact type and duration
- Temperature and working conditions
- Relevant breakthrough and degradation data
- Intended task and glove-use instructions
Important: A laboratory permeation result does not establish a universally safe wearing time in every workplace.
Step 3: Read the EN 388 Mechanical Performance Marking
EN 388 describes specified mechanical performance tests for protective gloves.
Jiali JNI documentation lists:
EN 388: 4101X
The positions in this marking correspond to different mechanical performance test results. The X in the marking means the applicable test result is not available or not applicable as defined by the standard.
Do not interpret the overall code as a single quality score. A glove may perform differently under abrasion, cutting, tearing and puncture-related test conditions.
Procurement teams should compare the actual marking and supporting test information with the hazards of their work.
Step 4: Do Not Confuse Microorganism Protection with Virus Claims
Jiali JNI documentation also lists EN ISO 374-5 for microorganism protection.
This reference should not automatically be rewritten as “virus resistant.”
Claims relating to protection against viruses require the applicable additional evidence and marking.
If the supplied document refers to microorganisms without a supported virus claim, the product description should remain limited to the documented scope.
Step 5: Understand What EN 421 Does and Does Not Mean
EN 421 addresses protective gloves for specified ionizing-radiation and radioactive-contamination hazards, depending on the applicable requirements.
For Jiali JNI, the documented application must be interpreted within the relevant certificate scope.
EN 421 is not an antistatic glove standard.
It should not be used to advertise ESD or electrostatic-dissipation performance without appropriate separate evidence.
Step 6: Check the Actual JNI Construction
Protective performance documentation must correspond to the actual glove construction.
Jiali’s JNI published commercial specifications include:
- Synthetic nitrile rubber
- Green exterior
- Nominal palm thickness: 15 mil, approximately 0.381 mm
- Length: 330 ± 10 mm
- Sizes: 7/S through 11/XXL
- Flock-effect interior construction
The product’s technical file describes the interior as White Polyester Nap Backing. This should not be represented as a traditional cotton flock lining or an unlined glove.
Commercial nominal palm thickness and thickness measurements at other test locations must not be treated as interchangeable.

Step 7: Request the Complete Documentation Package
Before purchasing industrial gloves for an EU PPE application, ask the supplier for the documents relevant to the exact product and destination market.
Depending on the product and applicable requirements, this may include:
- EU type-examination certificate
- EU Declaration of Conformity
- Applicable Module C2 or Module D conformity assessment information
- Instructions for use
- Technical product specification
- Relevant performance documentation
- Product labeling and traceability information
Verify the consistency of product names, markings, certificate references and manufacturer details.
A certificate number printed on a quotation is not a substitute for reviewing the actual documents.
Jiali publishes the reference information for its applicable products on the Certifications & Compliance page.
Frequently Asked Questions
Does a Module B certificate alone complete Category III CE conformity assessment?
No. Category III PPE requires Module B together with the applicable Module C2 or Module D procedure under Regulation (EU) 2016/425.
Does EN ISO 374-1 Type A mean protection against every chemical?
No. The marking relates to performance against specified test chemicals under defined conditions. Chemical compatibility must be assessed for the actual work.
Is an EN ISO 374-5 microorganism claim the same as a virus-protection claim?
No. Virus-related claims require their own applicable supporting evidence and marking.
Can the JNI certificate be used for Jiali household latex gloves?
No. JNI and JLHL are different glove series with separate product documentation and certificate scopes.
