EN388 gloves wholesale decisions should never be based on price alone—especially when safety and compliance are at stake.
When evaluating gloves for bulk procurement, a cut resistance level printed on a label is only meaningful if the testing method behind it is known and verifiable.Simply labeling a product as “Level 5 Cut-Resistant Gloves” makes it difficult to convince customers; such a label fails to specify the testing method employed, the company that conducted the testing, or when the most recent test was performed. Two gloves with the same label can perform very differently on the job.
EN388:2016, CE, and EN420 are the standards that fill that gap. Together, they give wholesale buyers a consistent, auditable basis for comparing products across suppliers — and for defending sourcing decisions if a compliance question arises later.
This blog guide will cover three key aspects: the specific content of our practical testing procedures, the inherent limitations of those standards, and the specific documentation you should request before finalizing a large-volume order. Our aim is to demonstrate the professionalism and transparency of our manufacturing processes here at Rilong Gloves, as well as the overall reliability of our brand.
EN388:2016 Explained — How to Read the Label Before You Order
The EN388:2016 label on a glove carries a six-character code that summarizes its performance across five mechanical tests. Reading that code correctly — and knowing which characters to prioritize for your specific procurement use case — is more useful than comparing headline claims between suppliers.
The 2016 update introduced one significant change relevant to bulk buyers: the addition of the TDM-100 straight-blade cut test (ISO 13997), represented by a letter from A to F in the fifth position of the code. This replaced sole reliance on the COUP rotating-blade test, which produced inconsistent results when applied to modern high-performance fiber blends. For buyers sourcing high-performance cut-resistant gloves for industrial use, the TDM letter is now the more reliable indicator of real-world cut protection.
The table below breaks down each position in the EN388:2016 code, what it measures, and the performance level Shandong Rilong’s certified product lines achieve.
| EN388:2016 Metric | Testing Mechanism | Scale | Shandong Rilong Standard |
| A – Abrasion | Martindale abrasion machine cycles | 1 to 4 | Level 4 (8,000+ cycles) via advanced nitrile foam. |
| B – Cut (COUP) | Rotating blade index | 1 to 5 | Exceeds 20.0 Index (often marked ‘X’ if TDM is used). |
| C – Tear | Force to tear apart liner | 1 to 4 | Level 4 via high-tensile HPPE/Nylon blends. |
| D – Puncture | Force to penetrate with standard spike | 1 to 4 | Level 3/4 based on coating thickness and density. |
| E – Cut (TDM-100) | Sustained straight blade force (Newtons) | A to F | Level F (30 Newtons) for severe industrial risks. |
CE Marking — What It Means for EU Market Wholesale Buyers
The CE mark on a glove is not a quality rating — it is a legal declaration that the product meets the requirements of the EU PPE Regulation (EU 2016/425) and has been assessed by a recognized third party.
Mechanical safety gloves fall under Category II (Intermediate Risk), which means factory self-certification is not permitted. The glove must be tested and approved by an independent Notified Body — a laboratory authorized by an EU member state to carry out conformity assessments. The four-digit Notified Body number printed next to the CE mark on the glove identifies which body issued the approval and can be cross-referenced in the EU’s NANDO database.
For buyers sourcing heavy-duty latex foam coated work gloves intended for EU market distribution, confirming Notified Body certification before production begins is a prerequisite — not a post-shipment check. Gloves placed on the EU market without valid Category II certification expose the importer, not the manufacturer, to regulatory liability.
EN420 — The General Requirements Standard Buyers Often Overlook
EN ISO 21420 — formerly EN420 — defines the baseline requirements that apply to all protective gloves, regardless of their mechanical or chemical rating. Where EN388 tests what a glove resists, EN ISO 21420 tests whether the glove itself is safe to wear.
The standard covers four areas relevant to wholesale buyers: sizing consistency across production batches, dexterity performance, pH safety of materials in contact with skin, and limits on harmful chemical substances — including DMF (Dimethylformamide), a solvent used in PU coating processes that can cause dermatitis and liver toxicity at sustained exposure levels.
For buyers sourcing industrial anti-static gloves or any coated glove intended for prolonged skin contact, EN ISO 21420 compliance is the document that confirms the glove won’t harm the worker wearing it. Request the EN ISO 21420 test report alongside the EN388 report — a glove that passes mechanical testing but fails chemical safety parameters is not legally compliant for EU market distribution.
At Shandong Rilong, our certified product lines maintain DMF content below 10ppm across all coated variants, verified through third-party laboratory testing.
How to Verify Certifications Before Placing a Bulk Order
Certification claims are only as reliable as the documents behind them. Before committing to a bulk order, there are three levels of verification worth completing.
The first is the Declaration of Conformity (DoC). This is the manufacturer’s formal statement that the product meets the requirements of the applicable EU directive. It should identify the specific product, the standards it was tested against, and the Notified Body that conducted the assessment. A CE logo on a product image or website is not a substitute for this document.
The second is the full test report from the Notified Body. This should show the actual test scores — not just the final rating — for each EN388 performance category. The four-digit Notified Body number printed next to the CE mark on the glove identifies the issuing laboratory. This number can be cross-referenced against the EU’s NANDO database to confirm the body is currently authorized.
The third is batch-level traceability. A certification that covers a product line does not automatically guarantee that every production run meets the same standard. Ask whether the supplier maintains batch records linking each shipment to a specific production date and quality control check.
At Shandong Rilong, we provide the Declaration of Conformity, full EN388 and EN ISO 21420 test reports, and batch traceability records with every order. Third-party inspection by SGS or any buyer-appointed auditor is available upon request.
What Shandong Rilong’s Certifications Cover — And What They Don’t
We are a direct manufacturer, not a trading middleman. As detailed on our company profile, all our mechanical PPE products are traceable from raw material sourcing through to final vulcanization. Our certifications cover our proprietary production lines, achieving compliance at scale.
However, quality cannot be magically guaranteed on micro-orders. Our MOQ of 3,000–6,000 pairs is fundamentally an engineering requirement. Running automated dipping lines for 18-gauge nitrile at this volume ensures the temperature stability needed to maintain EN388 Level 4 abrasion consistency across the entire batch. With a lead time of 7–25 days, you receive wholesale pricing (20%+ savings) without sacrificing certified safety.
Procurement FAQ
1. How does the TDM-100 test impact EN388 2016 gloves bulk orders?
The TDM-100 test provides a highly accurate reflection of real-world cutting hazards by applying directional force in Newtons. For bulk orders intended for metal fabrication or glass handling, specifying a TDM rating (A-F) guarantees the glove will perform under severe pressure, whereas the old COUP test (1-5) may overestimate the protection of glass-fiber-blended yarns.
2. Can CE certificates be transferred from a trading company to my brand?
No. If you are operating a Private Label or OEM model, the CE certification must legally reflect your brand as the “economic operator” placing the product on the EU market. Shandong Rilong assists our OEM buyers in navigating the Technical File submissions to Notified Bodies to ensure your branded gloves are legally compliant.
3. Why is DMF testing part of EN ISO 21420 (formerly EN420)?
Dimethylformamide (DMF) is a solvent commonly used in PU glove manufacturing. Sustained skin exposure to high levels of DMF can cause severe health issues, including liver toxicity. EN ISO 21420 sets strict chemical limits. By employing advanced washing processes, we keep our DMF levels below 10ppm, completely neutralizing this liability for wholesale buyers.
