Ordering and supply
What is the minimum order quantity?
Trade band orders can run from a single vial on a catalogue SKU, because the qualification step matters more than the quantity at the start. Volume and contract bands work per SKU and per total order value, and the break points are stated in every quote. For custom synthesis the MOQ is driven by synthesis economics — one vial is possible, and the quote will say so plainly.
Do you sell to individuals or only to businesses?
Only to businesses. Every enquiry is subject to drug licence verification and all trade is on a business-to-business basis. We supply to licensed distributors, manufacturers, institutional research buyers and hospital procurement.
How fast can you quote?
Normally within one business day of a complete enquiry — sequence, quantity, grade, destination and incoterm. An enquiry missing the specification will come back with a question, not a price.
Can you supply a sequence that is not in your catalogue?
Yes. Send the full sequence and the application, and we will run a feasibility review and quote. See custom peptide synthesis.
Do you sell research-use-only material for human or veterinary use?
No. All material is research-grade, for in-vitro use only. Buyers are responsible for compliance with the laws and regulations in their own jurisdiction, and we will not supply for a human therapeutic end-use without a written regulatory position from the buyer.
Quality and documentation
What does the Certificate of Analysis contain?
Product identification, batch number matching the vial, HPLC purity with the chromatogram, peptide content in mg per vial, counter-ion, water content, physical description, storage conditions with a retest date, and an authorised analyst signature. Mass spectrometry confirmation is included on every lot in the Verified and Characterised grades. Our guide to reading a peptide COA sets out the six things to check.
Will you provide raw analytical data?
Yes — the instrument printout with its run identifier and date. Every supplier who has actually run the test can produce it, because the instrument generates it.
Can I verify a lot independently before committing to a recurring order?
That is exactly what our lab-testing service is for. We publish third-party HPLC test reports for every reference standard we sell, and we will test a sample of any material against a reference standard on request.
What purity should I order?
It depends on the application. Standard grade at ≥95% suits screening. Verified at ≥98% with mass spectrometry suits binding and functional assays. Characterised adds endotoxin, residual solvents, amino acid analysis and stability data, and is what institutional and pharmaceutical buyers usually specify. We will recommend a grade if you tell us the application.
Shipping and delivery
How long does dispatch take?
Catalogue SKUs normally dispatch within 2–3 working days. Custom synthesis is 10–18 working days for a standard sequence, longer for complex modifications. Manufacturing time and analytical characterisation are sequential, not parallel.
Do you ship cold chain?
Lyophilised research peptides ship at ambient with cold packs by default. If your destination requires 2–8 °C, say so at RFQ stage — temperature-controlled logistics adds 30–50% to the freight charge and changes the packing specification.
Which incoterms do you work on?
EXW, FOB, CIF and DAP as standard; DDP by arrangement. We will quote on whichever basis you need so that competing quotes are comparable. See Incoterms and shipping terms.
How long does a shipment take once dispatched?
Typically 3–6 business days for the major destinations we ship to, plus customs clearance time in the destination country. We dispatch with the document pack pre-reviewed by your broker wherever possible, which is the single biggest factor in clearance speed.
What happens if a lot fails verification on arrival?
Send us the independent test result and the batch number. We will either replace the lot or credit it against the next order, on a timeline we agree at contract stage. That timeline is written into the agreement, not left to be negotiated after the fact.
Customs, duty and payment
What HS code do research peptides fall under in India?
Chapter 29 — 2937 19 00 for polypeptide and protein hormones, 2937 90 90 for non-hormone research peptides and blends. BCD is 7.5%, SWS is 10% of BCD, and IGST is 18% on the assessable value plus duty. Full detail, including a worked example and the legitimate routes to reduce the cost, is on our HS code and import duty page.
Do you issue a Certificate of Origin?
Yes, through Pharmexcil for pharmaceutical goods. Where a preferential rate is claimed under a trade agreement we will also supply the supporting origin evidence for the actual synthesis site. See export documentation.
What are your payment terms?
T/T with 30% on purchase order and 70% against shipping documents is standard for a first order; LC at sight on larger orders; and agreed credit terms for contract-band supply. See payment terms.
Do you supply to my country?
We ship to 40+ countries. Our country guides cover the destinations we ship to most: United States, United Kingdom, European Union, UAE, Australia, Japan and Singapore.
Still unanswered?
Send the question to the trade desk. If it is a technical question about a specific sequence, it goes to our QC lead rather than to a sales inbox — and you will get an answer about the molecule, not about our catalogue.
