Consolidating Several Refrigerant Grades Into One Container for East Africa: What the Documents Require

Mon, 26 Oct 2026 · HANGRUI HOLDINGS LIMITED

← All buyer guides

The short answer: a mixed-grade container to East Africa fails on paperwork far more often than on freight. Four documents have to agree line by line, one country-specific conformity certificate has to be obtained before the goods leave, and the segregation between the UN numbers has to be shown on the loading plan — not asserted in an email.

1. What can share a container, and what cannot

The rule that catches people: class 2.1 (A2L) next to class 2.2 is allowed, but the container has to show both placards and the packing list must carry the class per line. A single “refrigerant gas, non-flammable” line covering the whole load is wrong the moment one A2L grade is inside.

2. The certificate that has to be obtained before shipment

Kenya, Tanzania and Uganda each run a pre-shipment conformity programme: the goods are inspected and certified in the country of supply, and the certificate is presented at clearance. For a consolidated load this means:

• the inspection covers the whole consignment as declared — adding a grade after the certificate is issued means a new inspection;
• the certificate references the invoice and the packing list, so those two documents have to be final before the inspection, not after;
• a container that arrives without it is held at the port, and the cost of that is measured in storage, not in freight.

Practical consequence: the sequence is grades fixed → documents final → inspection → container loaded → vessel. A supplier who loads first and documents later cannot deliver this sequence.

3. The four documents that must agree

Customs and the conformity body read these against each other. A mismatch on one line stops the whole container — the container is one declaration, not ten.

4. Where the segregation is shown

The loading plan is not a formality: it is the document that shows the stowage complies.

• cylinders and drums are not mixed in the same block when the classes differ;
• A2L cylinders go where the ventilation and the placards can be seen from the door;
• the container position of each grade is drawn, not described — “mixed load, stowed per IMDG” is not a loading plan.

5. What a trader has to be able to do

Consolidation splits into two jobs, and they are usually done by two parties:

The value a trading company adds is in the first: it can hold several grades against one order, and it documents each of them so that the second party can load without re-sorting.

FAQ

Can several refrigerant grades with different UN numbers travel in one container? Yes — the segregation between classes has to be met and each grade documented separately; the packing list carries UN number, class and net weight per line.

What is checked before a refrigerant shipment enters Kenya? A pre-export verification of conformity, carried out in the country of supply before shipment; without the certificate the container is held at clearance.

Which documents must agree? Invoice, packing list, transport document and the SDS for each grade — on proper shipping name, UN number, class, packing group, net quantity per line and package count.

Who consolidates — supplier or forwarder? The supplier consolidates commercially, the forwarder physically. A supplier that cannot document each grade separately cannot deliver a clean consolidated container.

What the group provides

Who supplies this: HANGRUI HOLDINGS LIMITED is a chemicals trading group. The shipment is contracted, invoiced and shipped by the group operating company named on the quotation and on the documents — HARMONY TECHNOLOGY (ZHEJIANG) CO., LTD. for international trade, QUZHOU HUAFU NEW REFRIGERATION MATERIAL CO., LTD. for storage and cylinder filling, RIBOLUO CHEMICALS (ZHEJIANG) CO., LTD. for distribution. The group trades and distributes; it does not manufacture.

For a consolidated order the group issues: one invoice with one line per grade, a packing list carrying UN number and class per line, the SDS for each grade, and the loading plan showing the stowage — and names the conformity route for the destination before the goods are loaded.
