Plumbing and HVAC products depend on local standards for threads, pipe sizes, water contact and refrigerants, so a part that fits in one country may not fit or be approved in another. Choose a target market first, then check approvals and installer preferences before you stock.

Pipe threads and sizes differ between regions: parallel and tapered threads such as BSP and NPT look similar but do not seal against each other, and pipes are sized in metric or inch systems. Fittings come in compression, push-fit, solder, press and threaded types, and installers in each country have strong habits. Stock what local installers already use. Common materials are brass, copper, PVC, polypropylene and cross-linked polyethylene, and each has a limit on temperature and pressure.
Fittings, taps and pipes that touch drinking water are controlled in many markets, with limits on lead and other substances. Approval schemes include national bodies such as NSF in the United States and WRAS in the United Kingdom, and other countries have their own. Check the rules for your market, and ask for the approval documents as well as a catalogue claim.
Heating and cooling equipment carries more rules than most trade goods:
Small fittings come in bags or boxes of set quantities, and assortment kits suit plumbers who want a range. Radiators, boilers, tanks and units are heavy, bulky and damaged easily, so pallet freight and careful receiving matter. Returns on plumbing products are difficult once a part has been installed, so agree how defective goods are handled.
Fittings are low in value per piece and move steadily, with margin in range depth and availability when a plumber needs a part today. Boilers and heating products sell mostly before and during the cold season, and air conditioning peaks before summer, so order ahead and avoid carrying unsold seasonal stock through the off-season. Branded boilers and heat pumps are often limited to authorised sellers, which affects where you can buy.
They should not be, because the thread forms differ and joints can leak or fail. Check the thread type on every product against your market.
In many markets they do, with limits on lead and other materials. Check the rules for your market and ask for the approval documents.
Refrigerant and installation rules limit who may handle or fit units in some countries. Confirm what applies in yours before you stock them.
Everyday fittings, valves, tap parts and pipe sell steadily all year. Heating products peak before winter and cooling products before summer.
