India is a major sourcing hub for APIs, intermediates, specialty chemicals, solvents, and formulations from clusters including Hyderabad, Ahmedabad, Vadodara, and Baddi. China is the largest international source - antibiotics, vitamins, amino acids, and intermediates, with 20+ verified manufacturer relationships built over two decades. Germany supplies high-purity specialty chemicals and pharmaceutical solvents. Russia covers vitamins, amino acids, and select APIs. South Korea is strong in fine chemicals and advanced intermediates.

Additional sourcing countries: Taiwan, UAE (re-export hub), Bangladesh (generic APIs and formulations), Sri Lanka (intermediates and health products), Latin America, and Canada.
Yes. India is now a primary source country for Sumsahi Kemicals alongside China, Germany, and other established markets. Product categories sourced from India include APIs and Advance Stage Intermediates, pharmaceutical intermediates, specialty chemicals, solvents, nutraceuticals, herbal extracts, and finished formulations. Sumsahi draws from major Indian pharmaceutical manufacturing clusters - Hyderabad (oncology and anti-infective APIs), Ahmedabad and Vadodara (antibiotics, solvents), Baddi and Nalagarh (formulations), and Delhi NCR. All manufacturers are pre-qualified against applicable GMP standards including WHO-GMP, EU-GMP, and USFDA certification.
Yes. Sumsahi Kemicals specialises in sourcing pharmacopoeial grade APIs including United States Pharmacopeia (USP) grade, British Pharmacopoeia (BP) grade, Indian Pharmacopoeia (IP) grade, and APIs with USDMF (US Drug Master File) or global DMF filing support. The company has established sourcing channels for GMP-certified manufacturers holding USFDA, EU-GMP, and WHO-GMP approvals, covering antibiotic APIs, antiviral compounds, cardiovascular APIs, hormones, vitamins, oncology APIs, and new bulk drugs not yet widely available in the market.
Sourcing APIs from India requires defining a precise technical specification - CAS number, pharmacopoeial grade (IP/BP/USP), purity percentage, particle size, and residual solvent limits - and identifying GMP-certified manufacturers in clusters such as Hyderabad (oncology APIs), Gujarat (antibiotics and solvents), Baddi (formulations), and Aurangabad (speciality APIs). All suppliers must be certified for the target market's regulatory framework. Working with an experienced indenting house such as Sumsahi Kemicals - which has pre-qualified manufacturer relationships across India - significantly reduces sourcing time and compliance risk.
Yes. Sumsahi Kemicals provides Drug Master File (DMF) preparation support for both CDSCO-India submissions and US DMF (USDMF) filings. Services include assembling the required technical dossier, coordinating Certificate of Analysis (CoA), GMP certificates, MSDS, and manufacturer qualification documentation. Sumsahi also assists with product registration liaison for Indian and international markets, covering both new APIs and existing compounds from international manufacturers being introduced to new markets.
A reliable specialty chemicals supplier should hold verifiable GMP certification (WHO-GMP, EU-GMP, or USFDA), ISO 9001 accreditation, and ICH Q7 compliance - with all certificates confirmed directly from the issuing authority rather than from supplier-provided copies. Beyond documentation, evaluate supply reliability history, technical document quality, Certificate of Analysis accuracy, and post-shipment responsiveness. Red flags include reluctance to share full CoA details, absence of reference clients, and pricing significantly below market rate. Sumsahi Kemicals applies a structured vetting framework across its global supplier network.

Pharmaceutical APIs not previously approved in India require marketing authorisation from CDSCO under the Drugs and Cosmetics Act, typically via a Drug Master File (DMF) submission and a Form 10 import licence. Documentation includes Certificate of Analysis, GMP certificates, MSDS, and a technical dossier. Approval timelines range from 6 to 18 months depending on the product classification. Sumsahi Kemicals provides end-to-end registration support and coordinates all regulatory documentation between the international manufacturer and CDSCO or relevant state drug authorities.

An apostille is an internationally recognised authentication certificate issued by India's Ministry of External Affairs (MEA) that validates a document for use in any of the 124 Hague Convention member countries without further embassy verification. In pharmaceutical and chemical trade, apostille is commonly required for Certificate of Analysis (CoA), GMP certificates, Free Sale Certificates, and company incorporation documents when supplying to regulated institutional buyers in international markets. Sumsahi Kemicals offers end-to-end apostille and legalisation services from its New Delhi office, with with typical turnaround of 2-5 working days for apostille; embassy legalisation timelines vary by destination country.
The key documents requiring apostille or legalisation for pharmaceutical and chemical exports from India include: Certificate of Pharmaceutical Product (CoPP) - required by most regulated importers as proof of marketing authorisation and GMP compliance in the country of origin; Free Sale Certificate (FSC) - confirming the product is freely sold in India; WHO-GMP and GMP certificates - authenticating that the manufacturer meets Good Manufacturing Practice standards; Drug Master Files (DMF); Manufacturing Licences; Agreements and Power of Attorney; and Commercial Contracts when required for regulatory or legal submissions. The process for Hague Convention countries: PHD Chamber attestation then MEA apostille. For non-Hague countries: PHD Chamber attestation, then MEA attestation, then embassy/consular legalisation.
Apostille is a simplified single-step authentication issued by India's Ministry of External Affairs (MEA) that is recognised across all 124+ Hague Convention member countries - no embassy visit required. It is the preferred route for exports to the US, EU, UK, Australia, Japan, and most of Europe. Embassy attestation (consular legalisation) is required for countries not party to the Hague Convention - including Saudi Arabia, Qatar, Kuwait, UAE, Pakistan, Bangladesh, and several African and Asian markets. This is a multi-step process: PHD Chamber attestation, followed by MEA attestation, followed by submission to and collection from the destination country's embassy in New Delhi. Sumsahi Kemicals manages the complete process for both routes from its New Delhi office.
Yes. Sumsahi Kemicals assists licensed importers and exporters with the complete international trade process including: supplier invoice verification, Bill of Lading management, customs clearance and duty payment, export documentation preparation, Shipping Bill (SB) filing, Letter of Credit (LC) management, and buyer payment follow-up. The company facilitates both import of raw materials into India and export of Indian-manufactured APIs and chemicals to international buyers.
The best sourcing country depends on product category and regulatory requirements. China supplies approximately 40% of global API production and dominates in antibiotics, vitamins, amino acids, and intermediates. Germany excels in high-purity specialty chemicals and pharmaceutical solvents. Russia and Eastern Europe supply vitamins, amino acids, and select APIs. South Korea is strong in fine chemicals and advanced intermediates. Japan supplies precision specialty compounds. India is a major producer of generic APIs across all therapeutic categories. Sumsahi Kemicals maintains active sourcing relationships across all these markets.
A chemical indenting house is a specialist intermediary that sources, negotiates, and facilitates the supply of chemicals and pharmaceutical raw materials between buyers and manufacturers - without holding inventory. Operating on a commission or service-fee basis, it acts as the buyer's representative throughout procurement, managing supplier vetting, price negotiation, documentation, logistics, and compliance. Indenting houses are particularly valuable for cross-border sourcing where language barriers, regulatory complexity, and quality verification requirements make direct procurement difficult for most pharma procurement teams.
