If an error is found only after a customs hold, port storage, demurrage, a missed delivery window and reputational risk with the retail chain are added to the cost of the goods. Fixing it early at the warehouse in Sarkandaugava, before the goods go to EU buyers, usually costs no more than the relabelling and the agreed handling of the batch.
For a buyer with a regular replenishment cycle, certification readiness is critical no less than the price of a unit of goods: one returned batch can break the promo cycle of the network and remove the listing.
So the service is built for repeat work: preparing a series of batches to an agreed standard.
