# Peptides and oligonucleotides: Regulation

How solvent bans and US security laws reshape supply

Source page: https://www.materialinsights.org/chemicals/peptides_oligos/regulation/

What this tab covers How it is regulated and what could disrupt supply: hazard classification, rules in the EU, US and India, anti-dumping duties and other trade measures, and supply-risk notes.

#### Hazards

| Classification | UN number | Key risks |
|---|---|---|
| API-specific; process solvents DMF and NMP are reproductive toxicants (Repr. 1B) | API not regulated; DMF UN2265 | Solvent exposure in plants; TFA is corrosive. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **EU** | REACH restriction on DMF (Dec 2023) and NMP (2020) setting exposure limits | drives solvent substitution in SPPS |
| **US** | BIOSECURE Act (Dec 2025); FDA guidance on synthetic peptide ANDAs referencing rDNA origin (2021) | affects outsourcing choices and generic entry |

#### India

| Rule | Effect |
|---|---|
| **CDSCO approval of generic GLP-1s; patent expiry March 2026 (indicative)** | opens domestic market |
| **PLI for pharmaceuticals (Rs 15,000 crore) covers complex generics and peptides** | incentive for complex APIs (indicative) |

#### Trade measures

- US 1260H listing of WuXi AppTec (June 2026), preliminary injunction (Aug 2026)

#### Supply risk

Capacity is concentrated in a few CDMOs and originator plants; GLP-1 shortages in 2022-2024 showed supply could not keep up with demand.
