Compliance before speed
We do not offer shortcuts. A fast release built on a fragile declaration turns into a penalty with interest. We would rather explain the right route.
The firm
A technical partner, not a paperwork desk
COMEX HCY S.A.S. started in 2011 on a simple conviction: most customs problems are solved before they happen.
We are an Argentine customs brokerage, filing directly before ARCA, and we coordinate operations in three more countries in the region through licensed agents in each. We work with importers, exporters and free trade zone users on everything from a one-off shipment to continuous sourcing programmes.
That distinction matters and we say it plainly: in each country a locally licensed agent signs the filing, because each country requires it. What does not change is who builds, audits and answers for the file. See the detail country by country.
Our model rests on three deliberate decisions. First: every client has a named owner who knows their history, their product and their timings. Second: we review the documents at origin, not once the cargo is already accruing storage. Third: every technical position we take is written down with the regulation that supports it.
That last decision is what makes the difference when an audit arrives two years later. An orderly, defensible file is worth more than any one-off saving on a rate.

Our principles
What holds every operation up
Document traceability
Every operation leaves a complete file: supporting papers, positions taken and correspondence. If customs asks — in any of the four countries — the answer is already built.
A real point of contact
No call centres, no email chains without an owner. One person with a name, a direct line and knowledge of your account.
Anticipation
We flag a requirement or a regulatory change before it affects you, not once it has already cost you.
Positions that are grounded
Every classification and every valuation rests on current regulation and doctrine. Nothing is decided by habit.
Whole-chain view
We read your operation beyond customs: incoterm, transport, cost and cash flow are all part of the analysis.
