R410A Supply from China: Blend Composition, Documents and Terms
This is the supply page for R410A, the near-azeotropic 50/50 blend of R32 and R125 used in residential and light-commercial air-conditioning and shipped under UN 3163 as a liquefied gas, N.O.S. Minimum order, container load, loading port, lead time and packing are all confirmed in the quotation; none of them is fixed on this page.
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).

A blend adds one variable to each of those four fields: the composition tolerance you accept has to be fixed before a volume can be quoted against it. Send the quantity, destination port, packing form and the tolerance you work to, and the quotation will state minimum order, loading port and lead time together with the composition basis it is written against.
Specification basis
A blend is specified by composition, not by purity. R410A is R32 and R125 at 50/50 by weight; each component has its own CAS number and the mixture has none, so a specification that prints a single number for R410A is describing a different product. Our COA reports the composition and each component separately, against our own specification, per lot, and the tolerance accepted on each component is written into the quotation rather than left implicit. Moisture, acidity, non-condensable gas and residue are reported on the same certificate, each with the method behind the result, and no figure is carried over from an earlier lot.
Where a buyer names a standard, the quotation is made against that standard and the COA names it as the basis of analysis. Customs classification of a mixture is decided at destination and differs between administrations, so the quotation does not fix one; the documents state what the goods are, and the classification question is answered where the entry is filed.
Because R410A is near-azeotropic, its composition does not shift appreciably as it evaporates, which is why the grade is charged as a liquid in most systems — a point worth confirming with your equipment supplier rather than assuming across a retrofit.
