Five clusters. Thirty-three materials.
One European counterparty.

The cluster Serica knows most deeply. Multiple qualified producers per SKU, all REACH-mappable, with landed-cost equivalence already modelled.

We carry the construction families where the China-to-EU spread is structural rather than cyclical — rheology modifiers, redispersible powders, set accelerators and superplasticisers.

Pre-shipment QC coordinated through SGS or Intertek; documentation package issued before shipment. Single European point of contact across the engagement.

Food-, feed- and wine-grade ingredients sourced from producers with established export histories into the EU. Each SKU is mapped to its EU regulatory identifier (E-number where applicable) and ships with a complete COA/SDS/TDS pack.

Documentation rigour is the gate here, not price. Serica coordinates the producer documentation and, where required, third-party verification, so the buyer's QM team receives the dossier they expect.

A volume play. The economics of compounding mean a few percentage points of input cost cascade through every kilo of finished masterbatch — making this cluster particularly responsive to disciplined sourcing.

Serica provides landed-cost transparency and REACH-mapped documentation that compounders need to qualify a new origin internally.

Coupling agents and specialty silanes where small volumes carry meaningful spread. The technical sale matters here: grade equivalence, moisture spec, and packaging integrity are non-negotiable.

Serica's role is supplier qualification plus pre-shipment QC on every lot. Buyer receives a sealed, REACH-documented EU-counterparty shipment.

Predictable, repeat-purchase demand profile. Once a buyer qualifies an origin, the relationship tends to compound — which is exactly the buyer behaviour Serica is built around.

Documentation discipline (pharma-grade COA, lot traceability) is the differentiator versus marketplace sourcing.
