Buyer guides
- Consolidating Several Refrigerant Grades Into One Container for East Africa: What the Documents Require
Why a mixed-grade container to Kenya, Tanzania or Uganda is a documentation problem before it is a freight problem — the segregation rules between UN numbers, the pre-shipment conformity check each country runs, and the paper set that has to agree line by line.
- Electronic Specialty Gases in the Group's Range: the CAS List and How They Are Specified
A specialty gas is bought by substance and grade, not by brand: the CAS number fixes the substance, the specification sheet fixes the impurity limits, and a certified cylinder gets it to the line.

- Sourcing Chemicals from China: Six Checks Before the First Order
Six things a buyer can verify before the first order — business scope versus the dangerous-goods licence, no-storage trading, cylinder test dates, document consistency, carrier packs and payment terms — each with the question to ask.
- Supplying R410A and R134a into the EU: What the Supplier Does, and What Stays With the Buyer

A buyer's due-diligence map for a multi-entity Chinese supplier: the five documents to request, which entity legally holds each one, and the three questions a supplier's own website cannot answer.
