Getting your technicians onto a Chilean mine site

This is the failure mode nobody warns European industrial suppliers about, because everything written about Chilean mine site accreditation is Chilean compliance software marketing aimed at Chilean contractors.

The sequence goes: you win the order, you ship the equipment, you book flights for two commissioning engineers, and then the mine's contractor management system asks for documents you have never heard of and your people do not get through the gate. The equipment sits, the schedule slips, and the customer's view of you is formed.

Why the mine cares

Ley 20.123 regulates subcontracting in Chile and makes the principal, the mandante, jointly and severally liable for the labour and social security obligations of its contractors and subcontractors towards their workers. The mine can limit that liability by exercising its rights of information and retention, which in practice means demanding documentary proof of compliance before and during the work.

That is why mine sites run contractor accreditation systems. It is not bureaucracy for its own sake; it is a large company managing a statutory liability that attaches to your workers.

The main instrument in that process is the certificate of compliance with labour and social security obligations issued by the Direccion del Trabajo, commonly referred to as the F30 and, for the version covering a specific contractor's obligations towards its workers, the F30-1. A Chilean contractor pulls these routinely. A foreign company has no Chilean employment relationship to certify, which is precisely where the problem starts.

And then there is the safety regime

Separately from the labour question, mining operations are governed by the mining safety regulation, supervised by Sernageomin, the national geology and mining service. Site induction, medical fitness including altitude assessments, task-specific certifications for work at height, confined spaces, electrical work and lifting, and the mine's own rules all sit on top.

Altitude is not a formality in Chile. Several operations sit above 3,000 metres and some considerably higher, and there are occupational health requirements around intermittent hypobaric exposure that apply to your engineers as much as to anyone else's.

The four ways through it

Work through a Chilean contracting partner. The most common answer and usually the fastest. A Chilean industrial services company already accredited at the site provides the labour, and your specialist supervises. The commercial cost is a margin; the benefit is that the accreditation problem becomes theirs.

Use your own Chilean entity. If you have incorporated, you employ or contract locally and generate the certificates the system expects. This is the clean answer for a supplier with a continuing service obligation, and it is one of the stronger arguments for having an entity at all: see do you need a Chilean entity to sell to Codelco.

Send people as the foreign supplier and accredit as a foreign contractor. Possible, and the requirements are site-specific rather than uniform. Expect to provide apostilled corporate documents, insurance, and evidence covering your workers' status. Start this at contract signature, not at shipment.

Structure the contract so the customer's own people commission. Viable for simpler equipment, with your engineer supporting remotely or attending as a visitor rather than performing work. Note the distinction the site will draw between attending and working; a visitor badge does not authorise you to open a panel.

What to do at quotation stage

Put the accreditation requirement in the quote as an assumption, name who will hold it, and price it. Two lines of text at quotation stage prevent the most expensive week of the project.

Then ask the customer, before signing, three questions:

1. Which contractor accreditation system does this site use, and what does it require of a foreign supplier?
2. What is the lead time from document submission to gate access, in your experience with foreign vendors?
3. Are there altitude or occupational health requirements specific to this site for short-duration visits?

A procurement contact who cannot answer these will connect you to someone who can, and asking marks you as a supplier who has done this before.

Note that a long commissioning campaign has a tax consequence as well as a labour one, because extended on-site work can create a taxable presence: see withholding tax on services invoiced into Chile.

Common questions

What is Ley 20.123?

Chile's subcontracting law. It makes the principal jointly and severally liable for the labour and social security obligations of its contractors and subcontractors towards their workers, subject to rights of information and retention, which is why mine operators demand documentary compliance evidence before allowing anyone on site.

What is an F30-1 certificate?

A certificate issued by the Direccion del Trabajo evidencing a contractor's compliance with labour and social security obligations towards its workers. It is a standard requirement in Chilean contractor accreditation and is one of the documents a foreign supplier with no Chilean employees cannot straightforwardly produce.

Can a European engineer work on a Chilean mine site without a local entity?

Sometimes, through site-specific foreign contractor accreditation, and it depends on the operator. In practice most European suppliers either work through an accredited Chilean partner or use their own Chilean entity, because both generate the documentation the accreditation systems are built around.

How long does mine site accreditation take in Chile?

It varies by operator and there is no published standard. Treat it as a lead time item to start at contract signature rather than just before mobilisation, and ask the customer directly what they have seen with foreign vendors.
