Thread standard is where most first orders go wrong. Each of the 30 country pages names the fitting commonly used in that market — G1/2 BSPP across most of Europe, Asia and Africa, 1/2 inch NPT in the United States and Canada — and the adapter sizes ZHONGHE stocks for the head end: M22.1 x 1.5, M21.3 x 1.5, M21.5 x 2 and M22.1 x 1.75.
Each page also records the compliance route buyers usually meet in that market, the retail and marketplace channels that matter there, the port and typical sea-transit expectation, and a local-vocabulary table so a buyer can see the term their own customers search for. Every country fact is marked as what commonly applies and directs the reader to confirm with their customs broker or importer, because a factory is not the authority on another country's customs practice.
Sixteen of the pages are also published in the language of that market, with region-coded hreflang so a search engine can tell the en-DE page from the de-DE page.
