A CBRN glove that fails at the receiving dock has already cost the buyer a container and a customs entry. Imported consignments are where protective claims drift: the qualified sample may have come from a pilot line, while the shipped lot came off a press running a different compound batch, cure cycle or thinner fingertip. Quality control on arrival is the buyer's last chance to keep unproven barrier protection out of a responder's kit bag.
What Imported CBRN Gloves Are Built to Stop
CBRN gloves are the hand element of a sealed ensemble. They are tested against chemical warfare agents and toxic industrial chemicals, biological contamination during decontamination or medical response, and radioactive particulates, where an EN 421 containment glove may be called for. A glove rated for one class is not automatically rated for the others.
Protection follows from measurable construction factors. Multilayer laminates pair a thin barrier film with a textile carrier, buying longer breakthrough at the cost of dexterity; butyl and halogenated butyl rubber stay flexible in cold and resist many agents; fluoroelastomer grades suit fuels and solvents. Thickness is rarely uniform, so a glove can meet its nominal gauge at the palm and thin out at the fingertip - precisely where permeation is measured. A seamless dipped glove has no stitched joints to leak; any stitched or bonded seam is a potential permeation path. Under EN ISO 374-1, performance is expressed as Type A, B or C plus letter codes for the standard test chemicals, with permeation tested to EN 16523-1.
Documents That Must Tie Back to the Shipped Lot
Start with paperwork: it is cheap and filters out weak suppliers. Ask for the EU type-examination certificate under PPE Regulation (EU) 2016/425 with Module C2 or D surveillance, and check that its scope names the model, materials and construction actually delivered rather than a generic family approval. Confirm the Type A, B or C classification and the letter codes claimed, and the performance level behind each code, since level 1 and level 6 differ by a factor of forty-eight. Then match the lot marking to the production record, the manufacture date to the declared shelf life, and the permeation report to the finished glove rather than a flat coupon.
Sampling and Physical Checks on the Dock
Sample to a stated plan. ISO 2859-1 at general inspection level II is a common starting point, with zero acceptance for critical defects such as cuff tears, pinholes and delamination. Run the EN 374-2 air-inflation or water-fill leak test on the sample. Measure thickness at fingertip, palm and cuff, check length and cuff diameter against the size table, and verify the gauntlet laps a suit sleeve without gapping. Inspect packaging for compression creases, solvent odour or contamination, and retain sealed samples from every lot for the life of the warranty.
Task Fit, Field Care and Supplier Verification
A glove that passes inspection is only suitable if its class fits the job. Type A coverage suits entry work against unknown agents; Type B and C are reasonable where the chemical list is known and contact is brief. Field care decides how long protection lasts: store cool, dark and uncompressed, clean with approved agents only, inspect before and after each use for swelling, crazing or stiffening, and replace on failed inspection, suspected agent contact or the stated cycle limit, not on calendar age. Before ordering, confirm in writing the certificate scope, per-chemical breakthrough data with test standard and thickness, accredited reports for the exact model, ISO 9001 evidence for the site, lot traceability, and the remedy if a lot fails on arrival.
