If you manufacture or procure chemicals for pharmaceutical, food, or regulated industrial use in India, you have almost certainly encountered the designations IP, BP, USP, or NF on a Certificate of Analysis. These are pharmacopoeial grade references — and they are not interchangeable. Nor is the phrase "pharma grade" a valid substitute for any of them.
This guide explains what each standard means, which regulatory bodies recognise each, which to specify for your application, and what Supreme Petro Chemicals supplies across these grades.
What Is a Pharmacopoeia?
A pharmacopoeia is an officially recognised compendium of quality standards for medicinal substances — active ingredients, excipients, dosage forms, and reagents. For each listed substance, it specifies identity tests, assay methods, purity requirements, impurity limits, and acceptance criteria. Regulatory agencies and GMP auditors treat pharmacopoeial compliance as the minimum quality baseline for pharmaceutical-grade material.
Pharmacopoeias are updated regularly through addenda and new editions. A CoA referencing an outdated edition may not satisfy current GMP requirements — always confirm the edition cited against what your QA system specifies.
IP — Indian Pharmacopoeia
Published by the Indian Pharmacopoeia Commission (IPC), Ghaziabad, under the Ministry of Health and Family Welfare. Current edition: IP 2022 with subsequent addenda.
IP is the legally recognised standard under the Drugs and Cosmetics Act, 1940. Any drug substance or pharmaceutical-grade excipient manufactured or marketed in India for domestic use must comply with IP monographs where they exist. The IPC has progressively harmonised many IP monographs with BP and Ph.Eur test methods, so IP and BP grades are analytically equivalent for most common excipients — but IP remains the regulatory baseline for domestic Schedule M GMP compliance.
For procurement teams: specifying IP grade is the correct starting point for any chemical entering an Indian-market pharmaceutical formulation.
BP — British Pharmacopoeia
Published annually by the Medicines and Healthcare products Regulatory Agency (MHRA), UK. Current edition: BP 2025.
BP incorporates monographs from the European Pharmacopoeia (Ph.Eur) by reference, which means BP compliance effectively implies Ph.Eur compliance for most monographed substances. BP is the primary reference for UK, Commonwealth countries, Gulf and Middle Eastern markets, and much of South-East Asia.
In India, BP grade is widely accepted alongside IP for pharmaceutical procurement — particularly in export-oriented manufacturing and in plants operated by multinational pharmaceutical companies. Many Indian pharma companies specify BP as their procurement standard because it aligns with both domestic IP requirements and export market needs.
USP — United States Pharmacopoeia
Published by the United States Pharmacopeial Convention as the combined USP–NF (United States Pharmacopeia – National Formulary). Current edition: USP 47–NF 42.
USP is the reference standard recognised by the US Food and Drug Administration (FDA). For any chemical entering a US-market drug product — whether as an active ingredient, excipient, or processing solvent — USP or NF compliance is required. USP is also the de facto global standard for multinational pharmaceutical supply chains because of the FDA's reach and the broad international adoption of its monographs.
For Indian manufacturers operating USFDA-approved facilities or supplying US-market finished dosage forms, USP or NF grade with full batch CoA from the original manufacturer is non-negotiable.
NF — National Formulary
The NF is published as part of the combined USP–NF volume and covers excipients specifically — substances used as carriers, diluents, binders, solvents, humectants, and processing aids in pharmaceutical formulations. When a chemical is designated "NF grade", it means it complies with the NF monograph for that excipient.
The practical distinction: APIs and drug substances generally have USP monographs; excipients generally have NF monographs. Propylene glycol, polyethylene glycols, sorbitol, glycerine, and similar excipients are monographed in NF. Specifying "USP/NF grade" for an excipient is technically more precise than "USP grade" alone.
Ph.Eur — European Pharmacopoeia
Published by the European Directorate for the Quality of Medicines (EDQM), Council of Europe. Current edition: Ph.Eur 11.0.
Ph.Eur is the regulatory reference for the European Medicines Agency (EMA) and all EU national regulatory bodies. Because BP incorporates Ph.Eur monographs by reference, a material that meets BP typically also meets Ph.Eur. For Indian exporters to the European market or those holding EU-GMP certificates, Ph.Eur compliance may need to be explicitly confirmed on the CoA — not simply assumed from BP compliance.
FCC / FFG — Food Grade
FCC stands for Food Chemicals Codex, published by USP. It sets purity and identity standards for chemicals used in food processing, flavouring, and preservation. In Indian commercial practice, the term FFG (Food/Feed Grade) is commonly used for chemicals supplied to food and animal feed applications.
Food grade is not a pharmacopoeial standard. It is governed by FSSAI (Food Safety and Standards Authority of India) for the Indian market, and by the FDA or EFSA for US and EU food applications. A CoA marked "food grade" or "FCC" does not imply pharmaceutical compliance — the two standards have different test parameters and impurity limits. Never use food-grade material in pharmaceutical manufacturing without explicit QA approval and grade verification.

Which Grade to Specify — Practical Decision Guide
Manufacturing for the Indian domestic pharma market
Specify IP grade as the primary requirement. BP is broadly accepted as equivalent for monographed excipients, subject to your QA team's approval. "Pharma grade" without a pharmacopoeial reference is not acceptable under Schedule M GMP.
Manufacturing for UK, Middle East, or Commonwealth export
Specify BP grade. Confirm that the CoA cites the current BP edition and covers all relevant monograph parameters. For EU export, verify Ph.Eur compliance explicitly on the CoA — do not assume BP implies Ph.Eur without confirmation.
Manufacturing for USFDA-inspected plants or US-market products
Specify USP or NF grade depending on whether the substance is an API (USP) or excipient (NF). The CoA must reference the current USP–NF edition. For critical excipients, a Drug Master File (DMF) or CEP may also be required.
Food, flavouring, or FSSAI-licensed manufacturing
Specify FCC or food grade with FSSAI-compliant documentation. Do not assume pharma grade implies food-grade compliance — they are separate standards with different impurity profiles and test requirements.
Why "Pharma Grade" Alone Is Not a Valid Specification
In India's chemical trading market, "pharma grade" is widely used as a marketing label with no enforceable meaning. It could describe a genuine IP-certified batch from a licensed manufacturer with a complete CoA — or a standard technical product relabelled by a trader. For GMP compliance, the CoA presented to your QA team must state:
- The specific pharmacopoeial reference and edition (e.g., IP 2022, BP 2025, USP 47–NF 42)
- The batch number and manufacturing date
- Numeric test results for each pharmacopoeial parameter (assay, water content, heavy metals, residue on evaporation, specific impurities)
- The name and registered address of the original manufacturer
Without all four, the CoA is not GMP-compliant regardless of how the grade is labelled on the drum.

FAQ
Is IP grade equivalent to BP grade?
For many excipients, IP and BP monographs are harmonised and purity specifications are equivalent or very close. However, test methods, reference standards, and specific impurity limits can differ. Document which standard was tested — do not assume interchangeability without your QA team's confirmation for the specific substance and application.
Can BP grade be used for an IP-regulated product in India?
In Indian practice, BP grade is widely accepted as equivalent to IP for most excipients, subject to QA approval and documented justification in your material specification. Your internal SOP and regulatory affairs team should govern this — not the supplier's assurance. Some IP monographs reference BP test methods directly.
What if a chemical doesn't have an IP monograph?
If no IP monograph exists for a substance, BP or USP grade is typically accepted under Indian GMP guidelines, provided the relevant pharmacopoeial standard is documented in your Material Specification and approved by QA. The IPC also publishes supplementary standards for non-IP substances used in pharmaceutical manufacturing.
