Start with the destination country and the installation environment. A cable designation does not establish compliance in another country.
Share conductor material, AWG or mm² size, conductor count, voltage, insulation and operating conditions. Attach an approved drawing or datasheet if available. Ask for the exact scope of any proposed listing and manufacturing location covered.
Add quantity, reel lengths, labeling language, packaging, requested delivery window and Incoterms. Request written confirmation of feasibility, sample plan, documentation and lead time. TGS reviews each inquiry against the final requirements.
