Need EU-certified supplier for deck fittings or we lose the tender

We supply deck fittings and mooring hardware to a German shipyard, and their buyer just flagged our last batch: no EN 10204 3.1 certs for the cast steel, and the foundry we used can't issue them retroactively. Tender closes in six weeks and we need a new source fast. Spec is roughly 40t of cast steel bollards and fairleads, EN 10025 / relevant marine grade, hot-dip galvanized per ISO 1461, with full 3.1 material certs and traceability to heat number. We've tried two local foundries, one has no EN 10204 capability, the other quoted 14 weeks which kills the deadline. Anyone here sourcing similar marine castings with proper certification? Looking for a foundry or trading partner who actually understands 3.1 vs 2.2 and won't hand us a mill cert that fails at the shipyard's incoming inspection. Recommendations or warnings both welcome.
