What An Importer Signs Up For

What an Importer Signs Up For
A welding machine arrives, the container is opened, the invoice is paid, and from that moment a set of obligations attaches to the machine that the supplier in China cannot carry on the buyer's behalf. Most buyers discover this at the worst possible time: when a customer asks for a document that nobody has.
This article is about what the importer actually signs up for, in plain terms, and about which parts of it we can supply and which parts only the buyer can do.

Who the Importer Is
The importer is normally the entity that first places the machine on the market in that country: the company whose name is on the purchase, the one that takes delivery and puts the machine into use or into stock. On a direct sale to an end user, that is the end user. On a sale through a dealer, it is usually the dealer.
It stops being a formality when the machine is re-sold. An importer who buys a machine and then sells it on, or who substantially modifies it before putting it into service, can find that the obligations of a manufacturer have moved onto them. That is a question to ask before a machine is bought for resale, not after.
The File That Has to Exist Somewhere
The central obligation is to be able to produce a technical file for the machine, on request, for as long as the rules require. That file is not the manual. It is the evidence behind the manual: drawings, the electrical schematic, the risk assessment, the component declarations for the safety-related parts, whatever test evidence exists, the declaration of conformity, and the instructions in the language of the market.
The retention period is set by the applicable rules and is measured in years, not months; check the figure for your market rather than assuming it. The practical consequence is the same everywhere: the file has to live somewhere durable, not in an email thread.
Traceability: Knowing Which Machine You Sold
An importer is expected to know which machines they placed on the market and to be able to identify them afterwards. In practice that means the serial number of every unit, linked to an invoice and a customer, kept somewhere that survives a change of staff.
This is the obligation that fails most often and costs the most, because it fails silently. A machine with a fault and no serial trail cannot be traced to a batch, so the corrective action has to cover every unit instead of the affected ones.

When the Authority Writes
Market surveillance does not begin with an inspection of your premises. It begins with a request for the file, usually with a deadline measured in days. The answer has to come from documents, and it has to come from the importer, because the authority in that country has no relationship with the Chinese supplier.
A supplier can be helpful here, and a good one will be. But helpfulness is not the same as standing in the chain, and a file reconstructed after the request has arrived is worth much less than one that existed before it.
There is a cheaper version of this problem than a failed inspection. A buyer who cannot produce the file on request usually cannot produce it for their own customer either, and a tender that asks for a compliance pack will quietly exclude them. The file is a sales asset long before it is a legal one.
Incidents
If a machine turns out to present a risk, the importer is the one who has to act: stop supplying it, warn the users, correct it or take it back, and record what was done. The supplier's role is to give the importer the information needed to do that, quickly enough to be useful.
The test of a supplier is not the warranty clause. It is whether they can tell you, two years later, which transformer and which controller went into the machine you are being asked about. That is the kind of question a build record answers and a brochure does not.
What We Can and Cannot Do
We can supply the declaration of conformity for the machine as we build it, the drawings and schematic, the component declarations we hold from our suppliers, the test records from run-off, and the instructions in the language you need. We can answer questions about a specific serial years after delivery.
What we cannot do is be the importer in your country. We cannot hold the file on your behalf, we cannot be the contact address on the machine, and we cannot make a declaration that belongs to the entity placing the product on that market. On a turnkey project this is worth agreeing in writing before the order, because it decides whose name goes on the plate.
