What leaves the marsh, and in what state

We work with a single green macroalga, cultivated and harvested by us. Biomass is delivered fresh, drained or dried depending on your customer's use. Cells marked with a dash are waiting for a verified analysis; we do not publish a figure before we have it.

◦ One exclusive territory only: Romania, 2024

We do not publish a map of free territories

Availability changes with every season, so a map would be out of date within weeks. Tell us your market in the request and we confirm the situation of that territory before going further.

  1. You propose the market

    In the request you state the country or region and the sector your network serves.

  2. We confirm the situation

    We tell you whether that territory is free, whether there is already a counterpart, and on what terms you could enter.

  3. Territory is tied to volume

    Any territory reservation is tied to an annual commitment, never to a first order.

Territory exclusivity is assessed case by case. It is never granted on a first order, and in more than one market we have preferred not to close it. The Romanian case is told in full in our first export market.

◦ Own cultivation, harvest and dispatch

We cultivate it ourselves. We don't buy seaweed from anyone

That is why we can tell you which harvest day each pallet comes from, and why your end customer can ask for the analysis of the batch they bought.

One limit worth stating before signing: the marsh sets the pace. There are tide and weather days when nothing is harvested, and that conditions the schedule of a large shipment. We would rather move the date than promise a truck that would not leave.

◦ Reply within 24–48 working hours

Tell us your market. A person will reply

Tell us the country, the sector you serve and the annual volume you handle. We review every request by hand and reply with concrete conditions, not with an automated catalogue.

Importer questions

Do you supply other European Union countries?
Yes. We are a European producer, so goods move within the single market with no third-country import. Transport is arranged from Cartaya (Huelva) and lead time depends on the destination.
What is the minimum order?
It depends on the delivery state. In dried form you can start with a pallet; in fresh form the minimum is set by cold-chain logistics, because biomass leaves on the same day it is harvested.
Can I request a sample before buying volume?
Yes. We send a sample with its batch analysis so your team can validate it. State in the request which delivery state you need and the intended use.
Do you grant territory exclusivity?
It is assessed case by case and tied to an annual volume commitment, never to a first order. Today the only exclusive territory outside Spain is Romania.
What documentation comes with each shipment?
A delivery note with the batch number, the analysis of that harvest day and the specification sheet for the presentation supplied. If your market requires additional documents, say so in the request and we confirm whether we can issue them.

Before asking for a price, look at where the seaweed comes from

The marsh, the cultivation and the processing are documented with photographs and figures. It is what you will need to explain it to your own customer.
