Peanuts are grown mainly in Yunlin and Chiayi in central-southern Taiwan. Domestic consumption exceeds output, so a significant share is imported; once local and imported crop are blended during processing, buyers struggle to tell the origin.

Under the ministry's approach, the label carries the growing area, harvest period and handling firms. Participation is voluntary, and users must submit contract-farming records and reconciliations of inbound and outbound volumes.

Many observers say the scheme's value rests on verification. A label alone cannot prevent blending; sampling inspections and volume reconciliation in the distribution chain must run alongside. The ministry says the sampling rate will be higher in the early phase.

Origin labelling of nuts is a recurring practical issue for Chinese food distributors in Korea as well. Taiwanese peanuts often arrive as an ingredient for processed foods, so tightening labelling at the raw-material stage also firms up the basis for labels on finished products.

Whether the scheme takes hold will also show up in prices. If the label earns trust, a premium appears on labelled domestic product, and that premium has to flow back to contract growers for the system to hold. The ministry says it will monitor price data after launch.
