Chromium VI in Leather Gloves: Evidence Checks for Importers

Buyer guide to checking chromium VI leather gloves before quote approval, covering public limits, ISO leather test methods, component sampling, lab report wording, supplier claims, and approval controls.

Why quote approval needs chromium VI evidence

Chromium VI leather gloves should be screened as a component risk, not only as a finished-glove slogan. Leather can appear in palms, fingers, knuckle reinforcements, thumb patches, cuffs, binding, hang tags, and trim. Before a buyer approves a supplier quote, the evidence file should answer a narrow question: which leather components in the quoted style were checked, against which limit, and by which laboratory method? The first purchasing error is to accept a broad material claim as compliance evidence. A supplier-side safety glove article warns that no leather glove can be completely free of chromium and presents 99.9% chromium-free construction as a reduced-chromium claim, not as a regulatory pass. That distinction matters. Marketing language may describe a process or design goal, while the import file needs a lab result, sample identity, test method, and pass/fail basis tied to the offered product.

Use the glove standard as the baseline limit

The clearest numeric threshold in the supplied public source pack is the chemical-content update described for TS EN ISO 21420/A1:2024. That update states that chromium VI content in leather gloves is set at 3.0 mg/kg and that testing should use ISO 17075-1:2017 or ISO 17075-2:2017. For an RFQ, this can be translated into a requirement: every leather component supplied under the quoted style must have chromium VI results at or below the stated limit when tested by one of those methods. Do not write this as supplier is certified to the standard unless a current certification, declaration, or market-access document has actually been supplied. A standard requirement is not the same as the company's own practice. The useful quote language is narrower: supplier shall provide an independent laboratory report that identifies the sample, leather component, test method, result in mg/kg, and pass limit used for the buyer's destination market. Historical glove guidance points in the same direction. OHS notes that EN 420:2003 + A1: 2009 general requirements include pH and chromium VI content of leather and that these standards help manufacturers and suppliers support CE Marking. The takeaway is not to keep using an older citation automatically. It is to check that the quote, declaration, and lab report all reference the current standard expected by the buyer's market.

Map the leather before testing

A chromium VI check starts with the bill of materials, not with the certificate. Ask the supplier to mark every leather-containing part on the style drawing or tech pack. The map should distinguish the main leather shell from reinforcements, overlays, cuff binding, welt strips, patches, tabs, and decorative trim. If the glove is a leather-textile hybrid, the report should still identify which leather was tested. Color and finish should be treated as sourcing variables. A black grain-leather palm, a tan split-leather cuff, and a dyed reinforcement can be different evidence questions even when they sit on the same glove. If a laboratory report only names the finished glove but does not identify the sampled leather, the buyer cannot tell whether the highest-risk component was covered. A planning assumption to verify before use: if a style uses the same tannery, color, finish, and thickness across all leather parts, a buyer may choose a worst-case leather swatch for pre-quote screening. That assumption must be verified before use and should not replace a product-specific report needed for final approval.

Read the laboratory report like a specification

A usable report should name ISO 17075-1:2017 or ISO 17075-2:2017, state the result in mg/kg, and compare the result with the 3.0 mg/kg threshold when that standard basis is used. The report should also identify the sample by style code, material description, color, finish, supplier, and sampling date. If the report cannot be matched to the quoted style, treat it as background evidence rather than approval evidence. Ask for the full report, not only a pass certificate or screenshot. The report should show the testing laboratory, sample receipt information, method reference, result, and conclusion. If the supplier provides a declaration, it should point back to the laboratory report rather than replacing it. Where a buyer uses an internal restricted-substance list, the quote should state whether the lab compared results to the public standard limit, the buyer limit, or both. The same evidence habit applies to nearby glove chemistry. The USB Certification update cites ISO 3071:2020 for determining pH values of gloves, while OHS also places pH beside chromium VI content in leather under general requirements. pH is not proof of chromium VI conformity, but it can belong in the same quote evidence pack when the buyer is qualifying leather glove components.

Build a supplier quote checklist

A buyer-facing quote checklist should separate claims, evidence, and approval conditions. The material claim should say which leather is used. The compliance evidence should name TS EN ISO 21420/A1:2024 when that is the selected standard basis, the 3.0 mg/kg chromium VI limit, and ISO 17075-1:2017 or ISO 17075-2:2017 as the method. The approval condition should require a report traceable to the quoted style and component list. Use a simple status framework. Acceptable means the report is current for the quoted material, identifies the leather component, uses the agreed method, and shows a result at or below the stated limit. Conditional means the supplier has relevant evidence, but the sample identity, color, finish, or component scope needs clarification before order release. Hold means the quote relies on a marketing claim, an unrelated style report, an expired or incomplete document, or a method that does not match the buyer's specification. Also include change-control language in the quote. New evidence should be required if the supplier changes tannery, leather grade, dye, finish, coating, subcontractor, or construction. The buyer should retain the approved sample and the report together, because the lab document is only useful if it stays tied to the physical material that was approved.

Do not confuse chromium with other chemical checks

Chromium VI is a leather-specific approval question, but many work gloves combine leather with coatings, linings, membranes, adhesives, and synthetic reinforcements. The same USB Certification update gives a separate DMFa limit of 1000 mg/kg for polyurethane gloves. That figure should not be used to judge chromium VI in leather, but it shows why component-by-component evidence matters in a mixed-material glove. For a leather glove with a PU-coated palm patch or synthetic back, the quote evidence file may need separate tests for separate components. The chromium VI result answers the leather question. The DMFa result, if relevant to the construction and market, answers a PU chemistry question. A broad statement that the glove is compliant does not show which component was tested for which substance. This is also where buyers should be cautious with destination-market language. A supplier-side article cites California Prop 65 as a hazard-warning context for chromium VI, but the supplied source pack does not provide a concentration trigger for glove quote approval under that law. Do not substitute a glove-standard test limit for a warning-law analysis without checking the actual market requirement.

Approval rule before releasing the order

Before approval, the buyer should be able to put the quote, bill of materials, lab report, and retained sample side by side and see the same product. If the quote names a tan split-leather driver glove, the report should not be for a different color, a different leather finish, or a generic leather swatch with no link to the offered style. If the supplier cannot connect those records, approval should stay on hold. The practical rule is simple: no chromium VI leather glove quote should be approved on a material slogan alone. Require component mapping, the agreed public limit, the named ISO test method, a traceable laboratory report, and change-control terms. That evidence package does not remove every regulatory question, but it gives importers a defensible basis for screening chromium VI risk before price, packaging, and shipment planning move forward.
