What convergence is worth to a company

Regulatory approximation is usually framed politically, as a country adopting rules it did not write. A company sees something different: a change in what it costs to sell abroad.

The cost of divergence

A manufacturer selling into several markets with different technical requirements tests and certifies separately for each. Every additional certification is a laboratory fee, a delay and a variant of the product to keep in stock.

Small firms simply do not export under those conditions, because the fixed cost of entry exceeds the margin on the volume they could sell. Divergence is therefore a barrier that falls hardest on the smallest companies.

What convergence changes

One technical file, one set of tests, one declaration, and access to the whole market rather than one country in it.

A recognised standard also changes how a buyer treats an unfamiliar supplier. Purchasing departments assess risk, and a certificate they already understand removes most of the assessment.

The second-order effects

Lower financing cost, because a company with recognised certification is easier for a lender or insurer to evaluate.

Better internal quality, because the documentation the standard requires catches problems that were previously absorbed as scrap.

And access to supply chains, since a large manufacturer will not qualify a supplier who cannot demonstrate a system.

The honest cost side

It is expensive up front, and firms serving only the domestic market carry the cost without the benefit. That is a real objection and it is why transition periods exist.

The summary

For a company that exports or intends to, convergence is not a political question. It is the cheapest market access available.

Adopting somebody else's rules sounds like a concession; for an exporting firm it is a cost reduction, and it can be calculated. I have calculated it: building to two standards cost roughly a third more than building to one — separate tests, separate certificates, separate stock. The price of convergence is paid once; the price of divergence is paid on every shipment.
