A CBRN glove can pass every test it was submitted for and still fail an audit, because the buyer cannot demonstrate which glove the test applies to. At an airport or a border post the glove sits inside a chain of custody: a specification, a test report, a certificate, a label, and a carton that arrives months later. Each item is easy to obtain and difficult to reconcile with the others. The checklist below treats procurement as one verification chain, and asks the same question at every stage: does this record describe the glove I am buying, in the size I will issue, from the batch I will receive?
Write the Specification So It Can Fail
A specification written in adjectives cannot be verified. Every line should be a pass or fail statement naming the test method and its edition, for example a breakthrough time above a stated threshold for each chemical on your list, tested to the permeation standard your market recognises. Add the physical tests that matter at a border lane: tensile strength, puncture resistance, and leak tightness of the finished glove. State the size range by measured hand dimensions rather than small, medium and large, because a size that fits a warehouse hand will not necessarily seal under a uniform cuff. Finally, set a minimum remaining shelf life at delivery, not at manufacture, so the clock starts on your side of the shipment.
Make Every Record Point at the Same Glove
The most common gap is not a missing certificate but a set of documents that quietly describe different products. Use one anchor string throughout the purchase file: model, material code, size range and production batch. Then check the following.
- Does the permeation report cover the finished glove, seams and cuff included, or only flat sheeting?
- Does the certificate number resolve when you query the issuing body directly?
- Was the test run to the current edition of the standard, not the one superseded two years ago?
- Was the laboratory accredited for that specific method, and is the scope certificate still valid?
- Has the compound changed since the report was issued? Ask for written notification of any formulation change.
A supplier who cannot produce a model-to-report cross reference in writing is telling you something useful about the rest of the order.
Audit the Line That Will Run Your Order
Factory audits go wrong when they are conducted in the sample room. Ask to walk the line that will actually produce your batch: the dipping or lamination line, the compounding area, and the curing records. Look for calibration labels with dates, batch records that can be matched to retained samples, and a clear answer on whether any process is subcontracted. Ask how rework and regrind are handled, since recycled polymer in a barrier layer is difficult to detect afterwards but easy to declare.
Let the Label and the Arrival Sample Speak
The label is the only document that travels with the glove. It should repeat the model, size, batch, date of manufacture, expiry date and certification marks, in the language of the destination market. Cartons should carry the purchase order and batch reference, and sea freight needs desiccant and a pallet pattern that does not crush the cuff beading.
On arrival, sample to a stated plan, keep sealed approval samples from the first accepted lot, and test leak tightness plus thickness at fingertip, palm and cuff against those samples. Quarantine any lot that fails and record a written disposition. A lot marked pending issue tends to end up on a vehicle anyway.
