Known supplier risks in spices and saffron
Ground spices are a fraudster's ideal product: once milled, bulking agents and industrial dyes are invisible to the eye. The EU's coordinated control of herbs and spices found suspicious results in 17% of pepper, 14% of cumin and 11% of saffron samples, with oregano worst at nearly half. The documented patterns below each carry a public source and the control that beats it: ISO 3632 grading for saffron, HPLC marker testing, and origin analysis that reads the plant, not the paperwork.
These are documented industry-wide patterns from the public sources linked below, never statements about any specific company listed here. Factual pointers, not legal advice.
The documented patterns, and the control that beats each one
- 1
Bulking and industrial dyes in ground spice
High-value powders stretched with cheaper plant material (safflower or marigold in saffron, olive leaves in oregano) and 'refreshed' with industrial colorants such as Sudan dyes that are banned in food.
EU-wide coordinated control across 21 member states.
Your control: Buy whole spice where the process allows, and for powders require a certificate of analysis from an ISO 17025 accredited lab covering foreign plant material and illegal dyes (Sudan I-IV); for saffron, HPLC testing of crocin, picrocrocin and safranal against ISO 3632 grades.

Origin laundering of premium saffron
Bulk saffron from lower-priced origins is repacked in a premium country and sold under its name at several times the price; the certificate of origin reflects the packing house, not the field.
Documented for 'Spanish' saffron by university chemical-fingerprinting studies.
Your control: For origin-priced saffron demand the PDO certification document and re-check the protected name in the EU register; stable-isotope or multi-element analysis ties the batch to its real soil when the premium justifies the test.

Stale stock re-dated as fresh crop
Old saffron whose aroma compounds have decayed is blended with a little fresh crop, repacked and given a current-season production date at peak-season prices.
Your control: Contract on ISO 3632 category with a current-year harvest declaration, and verify with the degradation-sensitive markers (safranal, picrocrocin) in the pre-shipment certificate of analysis.

Before any prepayment
Advance-payment fraud (fake exporter sites, compromised email threads, too-good prices) hits every category, not just spices and saffron. Read the payment guide before wiring a deposit to a new counterparty, and run the company through the free checks first.

Questions
Is visual inspection of saffron threads enough?
No. Dyed safflower and corn silk pass a visual check. Only laboratory testing (HPLC against ISO 3632, plus a dye screen) distinguishes real grade-I saffron.
Which spices carry the highest documented fraud risk in the EU checks?
Oregano was worst (about half of samples suspicious, typically bulked with olive leaves), followed by pepper, cumin, curcuma and saffron. The full breakdown is on the European Commission's coordinated-action page linked above.
What protects a first saffron order best?
A letter of credit conditioned on an ISO 17025 lab certificate for the sealed shipment sample: ISO 3632 grade, dye screen, and foreign-matter check. It removes both the quality and the prepayment risk.
