- FedEx International
- UN3373 Category B only
- Yes (Sch III/IV)
- Yes (EU, AU, CA)
- High. Internal restricted articles list blocks many peptides regardless of permits
- Expect refusal for growth hormone secretagogues and anabolic analogs even with full compliance
- UPS Worldwide Express
- UN3373 Category B; rejects Category A
- Moderate-High. Case-by-case review delays shipments 7–14 days
- UPS applies manual compliance checks; approval not guaranteed even with permits
- DHL Express
- UN3373 and UN2814 with hazmat cert
- Moderate. Most permissive carrier but slowest customs clearance
- Higher acceptance rate but longest transit times due to customs holds
- USPS Priority Mail International
- Does not enforce IATA classifications
- No (not legally required but increases seizure risk)
- Very High. No carrier pre-screening means customs is the first inspection point
- USPS ships almost anything but offers zero customs support; highest confiscation rate
- The professional reality: legal compliance and carrier acceptance are separate gates. A shipment can pass every legal requirement and still be refused by the carrier's compliance team based on internal risk models.
