Tadalafil API Price per kg: What Drives the Cost of Bulk Tadalafil

Red Chem Biotech · Published · 2 min read

What sets the price of tadalafil API per kg: grade, documentation, volume, packaging and Incoterms. A buyer's checklist for comparing bulk tadalafil quotes.

Tadalafil is one of the most widely traded active pharmaceutical ingredients, and India is the dominant exporter. Because so many suppliers quote it, buyers often see a wide spread of prices per kilogram for what looks like the same material. The difference almost always comes from what is — and is not — included in the quote.

The five factors behind a tadalafil API price

  • Grade and specification: material tested to the current USP or EP monograph, with named methods and limits, costs more to release than material sold against a loose in-house sheet.
  • Documentation: a batch Certificate of Analysis and Safety Data Sheet are standard; residual-solvent (ICH Q3C), elemental-impurity (ICH Q3D) and nitrosamine statements add value for regulated buyers.
  • Volume: per-kilogram prices fall with batch size and with recurring, forecast orders.
  • Packaging: double polyethylene bags in fibre drums are typical; smaller packs and special labelling cost more per kilogram.
  • Delivery terms: an ex-works price and a delivered (CIF or DAP) price are not comparable until freight, insurance and duties are added.

How to compare quotes like-for-like

Ask every supplier to quote against the same written specification, the same quantity and the same Incoterm. Then compare what each quote includes: the grade claimed, the documents supplied before and with the shipment, the retest period on the batch, and the lead time. A cheaper quote that omits the documents your market requires will cost more once you have to fill the gaps.

Purity and identity: what to check on the COA

For tadalafil, the Certificate of Analysis should report identification (typically IR and HPLC retention), assay on a stated basis, related substances with the largest single and total impurities, residual solvents, water content and, where specified, particle size. Every result should sit beside its acceptance criterion and method. Red Chem Biotech supplies tadalafil at a minimum of 99.0% purity by HPLC, with the batch COA shipped with every order.

Checklist before you order

  • Confirm the grade (USP, EP) and the specification version

  • Agree quantity, packaging and Incoterm in writing
  • Confirm lead time and the retest date of the batch you will receive
  • Check import requirements for your destination before paying

Frequently asked questions

Why do tadalafil API quotes vary so much between suppliers?

Quotes differ mainly on grade (USP, EP or in-house), the documentation included (COA only versus a full dossier), batch size, packaging and delivery terms. A low price that excludes the documents your market requires is not comparable with a fully documented offer.

What is the minimum order for bulk tadalafil?

Red Chem Biotech supplies tadalafil in bulk from 1 kg, with volume pricing for larger and recurring orders. Paid evaluation samples are credited against the first bulk order.

Which documents should come with a tadalafil API order?

At minimum a batch Certificate of Analysis against the agreed specification and a Safety Data Sheet. Depending on your market you may also need residual-solvent and elemental-impurity statements and a certificate of origin.
