EU researchers face a constant decision when sourcing peptides: stay within the EU customs union or source from non-EU suppliers (often US-based, sometimes Asia-based). Chempeptides operates as an EU-internal supplier; Pepfactor and similar non-EU labs ship across customs borders. The practical implications for delivery, cost, and reliability are significant.
The customs friction factor
Shipments crossing EU external borders go through customs clearance. This adds:
- Customs declaration paperwork (CN22/CN23)
- VAT charged at destination country rate (typically 19-25%)
- Possible import duty (0% for HS 2937 in most cases)
- Customs broker handling fees
- 3-7 day average transit time increase versus intra-EU
- Customs hold probability of 5-10% for biochemical shipments
See our EU customs guide for full friction detail.
Transit time comparison
| Destination | Chempeptides (EU-EU) | Pepfactor (non-EU → EU) |
|---|---|---|
| Germany | 1-2 days | 5-10 days |
| France | 2-3 days | 5-10 days |
| Netherlands | 1-2 days | 5-10 days |
| Spain | 3-4 days | 7-14 days |
| UK | 3-5 days | 7-14 days |
The cold-chain implication
Cold-chain packaging provides approximately 72 hours of stable temperature protection with phase-change gel packs. Intra-EU transit consistently delivers within that window. Non-EU transit often exceeds it — particularly if customs holds extend handling. The result: sensitive sequences (GHK-Cu, BPC-157, TB-500) face higher cumulative heat exposure on non-EU routes.
VAT and effective cost
Headline prices can look favourable from non-EU suppliers — until VAT is applied at customs:
- Non-EU listed price: €100
- + Shipping: €25-40
- + VAT at 21% on (product + shipping): €26-29
- + Customs broker fee: €15-25
- = Effective landed cost: €166-194
Intra-EU sourcing eliminates the VAT-on-import step (VAT is included in the listed price) and the broker fee. The €100 listed Chempeptides product is €100 delivered (within EU).
Payment infrastructure
Chempeptides (EU): Regulated EU payment rails — iDEAL, Bancontact, SEPA, card processors, Bunq. Card-issuer fraud protection applies.
Pepfactor (non-EU): International payment methods, often crypto preferred. Card chargeback paths cross jurisdictions.
Customs hold probability
Non-EU shipments of biochemical material trigger customs inspection more frequently than intra-EU shipments. Hold rates of 5-10% for biochemical categories are typical at major EU entry ports. A held shipment can take 3-14 days to clear, during which the cold-chain integrity degrades.
When non-EU sourcing makes sense
- Specialty compounds genuinely unavailable from EU suppliers
- Bulk volume orders where price differential exceeds €200+ to offset customs friction
- Research protocols with sufficient lead time to absorb 2+ week delivery variance
When EU-internal sourcing wins
- Time-sensitive protocols (most research)
- Sensitive sequence compounds requiring cold-chain
- Small-to-mid orders where customs friction percentage is high
- First-time supplier evaluations
- Reliable delivery scheduling for experimental design
