Impact, falling objects, dust, cut and abrasion from rebar and formwork, plus visibility around plant. Zones most often specified: head, eye and face, hand, body, foot.
Machinery noise, swarf and sharp edges, coolant and light oil, press and sheet-metal work. Zones: eye and face, hand, foot.
Chemical splash, hot surfaces, flame and static considerations, and long shifts outdoors. This is the sector where the required standard matters most, and where we will ask for it before quoting.
Repetitive handling, slip and trip risk on hard floors, low-level head knocks, and high-visibility issue for visitors and contractors. Zones: hand, foot, body, head.
Wet and muddy ground, washdown, cold rooms, knives and blades. Zones: hand, foot, body.
Splash and aerosol exposure, chemical handling, and single-use volumes. Zones: eye and face, hand, body.

What is the person being protected from? Cut, impact, chemical, noise, heat, dust, slip. A hazard description is more useful to us than a product name.
If your market, insurer or customer requires a specific standard, say so at the start. It changes what can be offered, and it is the one thing that cannot be fixed later.
Approximate annual or per-order volume, and the size split if you have it. Mixed sizes in one carton can usually be arranged; it has to be specified up front.
Port of discharge, and whether you buy FOB or CIF. Packaging and marking requirements often follow from the destination market.
Own label, packaging artwork or plain OEM. If you have artwork files, send them with the enquiry rather than after the quotation.

Send a short description of the working environment, the hazards and the volumes. We will come back with the references that fit, and be clear about anything that does not.
