R22 Supply from China: Specification Basis, Documents and Quotation Terms

This is the supply page for R22 (HCFC-22, CAS 75-45-6, UN 1018), the HCFC still supplied to service existing air-conditioning and refrigeration equipment where the phase-out schedule under the Montreal Protocol still allows it. Commercial terms — minimum order, container load, loading port, lead time and packing — are not fixed on this page; each one is confirmed in the quotation you receive.

We are a trading company: the product is produced by a licensed Chinese producer and supplied under our own documentation. Group member Quzhou Huafu handles warehousing and cylinder filling for the cylinder grades in our range (R22, R134a, R410A).

Quantity and packing

These are the four fields buyers ask for first, and the four that cannot be published loosely: they move with grade, packing form, destination and shipping window. Send the quantity, the destination port and the packing form with the enquiry, and the quotation will state all four explicitly. Where a volume is quoted in cylinders, the cylinder count and the net weight are given together — one without the other does not tell you what is loaded.

Specification basis

R22 is quoted against our own specification, and every lot is certified against it. Purity, moisture, acidity, non-condensable gas and residue are reported per lot, with the test method behind each result, and no figure is carried over from an earlier lot: the number that counts is the one on the certificate for the lot you actually receive. Where a buyer names a standard — a national grade, an industry grade, or the buyer’s own purchasing specification — the quotation is made against that document and the COA names it as the basis of analysis, so your laboratory can read our results against the specification it already holds. If a specification needs review before you commit to a volume, send it with the enquiry; the answer comes back on paper, lot by lot.
