Importing Pirfenidone API From India: What to Expect From an API Exporter

By Jignesh Akbari, Director | Published by SNJ Labs Pvt. Ltd. on 24 September 2026

Demand for pirfenidone continues to grow as more generic products for idiopathic pulmonary fibrosis reach markets around the world. Many of those generics rely on API made in India, one of the world's largest API manufacturing bases. For an importer, though, buying API across borders involves much more than agreeing on a price. The regulatory documents, packaging and shipping arrangements matter just as much as the material itself.

This article explains what a Pirfenidone API exporter should provide, how documentation differs by market, and how shipments are packed and moved. For product enquiries, visit our Pirfenidone API exporter page. Learn more about the role of Indian API manufacturers in the global pharma industry.

Regulatory Documentation by Market

Market	Typical API documentation
United States	Type II Drug Master File filed with the FDA, referenced through a letter of authorization; FDA-registered site
European Union	Certificate of Suitability (CEP) from the EDQM, or an Active Substance Master File (ASMF); plus a written confirmation from the exporting country's authority
United Kingdom	Requirements aligned with the MHRA's API import rules
Latin America, Middle East, Asia, CIS and Africa	National requirements vary; often GMP certificate, technical package or open part of a DMF, COAs and stability data. Some countries have their own API dossier procedures.

The documents available differ from product to product. Before you commit, ask the exporter exactly what exists for Pirfenidone API and for your target market, and how long it takes to provide it.

Key Terms Every Importer Should Know

DMF (Drug Master File): a confidential file describing API manufacturing and controls, submitted to the FDA.
LoA (Letter of Authorization): permission from the API maker for a regulator to review its DMF on your behalf.
CEP: a certificate from the EDQM confirming that the API's quality is suitably controlled by the European Pharmacopoeia monograph.
ASMF: the European equivalent of a DMF, with an open part for the applicant and a restricted part for regulators.
Written confirmation (WC): a statement from the exporting country's authority, required for APIs imported into the EU, that the site follows equivalent GMP.

Commercial and Shipping Documents

Commercial invoice
Packing list with drum count, batch numbers and weights
Certificate of analysis for each batch
Bill of lading or air waybill
Certificate of origin
Safety data sheet
GMP certificate copy and any destination-specific documents

Documents must match exactly, including product name, grade, batch numbers and weights. Even small mismatches can hold a shipment at customs.

Export Packaging for Pirfenidone API

Primary packing: sealed, double polyethylene liners to protect from moisture and contamination.
Secondary packing: HDPE or fibre drums with tamper-evident closures.
Labelling: product name, grade, batch number, manufacturing and retest dates, net and gross weight, storage conditions and manufacturer details.
Palletisation: drums are palletised and secured for handling.

Air or Sea Freight?

Mode	Best for	Consider
Air freight	Samples, validation batches, urgent orders	Higher cost per kilogram, faster transit
Sea freight	Regular commercial volumes	Lower cost, longer transit, plan stock ahead

Agree on Incoterms, such as EXW, FOB, CIF or DAP, early so both sides know who arranges freight, insurance and customs clearance.

Frequently Asked Questions

What documents does a Pirfenidone API exporter provide with a shipment?

A typical API shipment includes a commercial invoice, packing list, certificate of analysis, bill of lading or air waybill, certificate of origin and safety data sheet. Depending on the destination, GMP certificates, a written confirmation or other regulatory documents may also be needed.

What is a DMF and a letter of authorization?

A Drug Master File (DMF) is a confidential submission to the US FDA describing how an API is manufactured and controlled. The API maker gives its customer a letter of authorization so the FDA can refer to the DMF when reviewing the customer's drug application.

What is a written confirmation for exporting APIs to the EU?

APIs imported into the European Union must be accompanied by a written confirmation from the exporting country's regulatory authority stating that the manufacturing site follows GMP standards equivalent to the EU, unless the country is on the EU's list of equivalent regulatory frameworks.

How is Pirfenidone API packed for export?

APIs are usually packed in sealed, double polyethylene liners inside HDPE or fibre drums, labelled with product name, grade, batch number, dates, weights and storage conditions, and palletised for transport.

Should Pirfenidone API be shipped by air or sea?

Air freight suits samples, validation batches and urgent orders. Sea freight is more economical for larger commercial quantities. In both cases the API should be protected from moisture and excessive heat as per its storage conditions.
