Cut-Resistant Gloves from China: The EN 388 Level Is the Least Useful Number on the Label

A distributor in Lyon told me he lost a customer over gloves. He had been buying level C cut gloves for a sheet metal fabricator, same specification for two years, same factory. Then the factory changed its liner yarn from HPPE to a cheaper HPPE and glass blend, the coupons still passed level C, and the gloves started failing in the field within three weeks instead of eight. The certificate was valid. The glove was different.

This is the fundamental thing to understand about buying protective gloves in China: EN 388 is a performance band, not a recipe. Passing a band only means the sample tested cleared the threshold. It says nothing about where in the band the product sits, and nothing about how it behaves after ten washes.

What EN 388 actually tests

The standard covers mechanical risks in four or five tests, reported as a string of digits. Abrasion is cycles on a rotating abrasive surface; cut resistance under the current edition is a TDM-based test that produces a score, mapped into levels A to F; tear and puncture are force-based. If the glove is marketed for impact protection there is an additional test, and for cold there is a separate EN 511 that people constantly confuse with the cut rating.

The label might read "4X43C" or similar. Those characters are not decorative and a supplier who cannot explain which character came from which test is a supplier who did not run the tests.

Why the letter is not enough

Cut level C and cut level D both mean "good". The gap between the low end of C and the high end of D is large in a real workshop. If your customer handles 0.8 mm cold rolled sheet with oily edges, a mid-range C is usually enough; if they handle glass or deburred stainless edges, they need to be at the top of C or into D, and the price difference is honest.

So specify a minimum score, not a letter. Say "cut score not below X" and ask the supplier to state the measured numeric result on the test report. Good factories will give you the raw number for each test and the lab name. Weak ones will email you a PDF certificate with a model number and no data.

The liner is the product

Cut resistance comes from the yarn. HPPE (high-performance polyethylene) is the workhorse, often blended with glass fibre, steel microfilament, basalt or nylon. Glass adds cut resistance cheaply and adds itch, pilling and breakage of the fine filaments over time. Steel microfilament is strong but heavy and can create false confidence because a glove can score well while being uncomfortable enough that workers take it off.

Gauge is the knitting fineness — 13, 15, 18 gauge. Higher gauge is thinner and defter and generally more expensive. An 18-gauge glove with the right yarn gives better dexterity for the same cut score, which in assembly work matters more than raw resistance because a glove people actually wear is the only glove that protects anyone.

Then the coating. Nitrile palm coatings give grip and oil resistance; polyurethane gives dexterity and a clean finish for handling small parts; latex crinkle gives the best dry grip; water-based PU is a premium for touchscreen and fine assembly. Coating thickness and whether it is a palm dip or a full dip changes both grip and breathability, and full-dip gloves sweat, which is why workers cut the fingertips off and destroy the protection.

The washing question nobody asks

Industrial gloves get washed. Cut resistance after five or ten domestic or industrial wash cycles can drop measurably, especially with glass-containing liners where the filaments abrade and break. Ask whether the supplier has wash-cycle data. Most do not, and the ones that do have a real selling point. If your customer has a laundry contract, this is a genuine qualification question rather than a nice-to-have.

Size, fit and the Chinese sizing trap

Chinese domestic sizing often runs smaller than European sizing at the same nominal number. Ask for the actual hand circumference and length dimensions per size on the spec sheet, and get two sizes in the sample order. A glove that fits badly is a glove that gets removed. I have seen distributors reject an entire shipment on this alone, and it costs nothing to check early.

Certification paperwork that holds up

For Europe, gloves under PPE Regulation need a type-examination certificate from a notified body, which lists the model and the sizes covered. Check whether the certificate names your exact model and whether it is still valid — certificates expire and get withdrawn. For the US, ANSI/ISEA 105 gives a different cut score scale (A1 through A9) that does not map one to one onto EN 388 levels, so a supplier quoting "ANSI A4 equivalent to EN level D" is simplifying and you should get both reports if you sell into both markets.

One more practical item: the user information. Gloves sold in Europe must ship with instructions and performance data in the language of the destination market. Chinese factories will print what you send them, which means if you do not send anything, you get a generic sheet. That is a compliance gap you own, not the factory's.

A short buying routine

Ask for the numeric test results and the lab, not the certificate alone. Ask for the liner composition and the yarn's supplier if they will share it. Ask about wash performance. Order two sizes and put one pair on someone who actually does the job for a week. Then buy the first order with a clause that ties the approved sample to production, with a retained sample from the approved lot sealed at both ends. It sounds bureaucratic for a glove. It is the difference between a two-year account and losing one over three weeks of wear.
