Supplying impurity reference standards to Nepal
Sea freight reaches Birgunj ICD (via Raxaul, road/rail) and Kolkata/Haldia (for third-country cargo) in about 6–10 days port to port. Urgent or small lots fly to Kathmandu Tribhuvan (KTM) in 2–4 days. Import compliance for this category sits with DDA (Department of Drug Administration), and we prepare the COA, SDS and commercial documents your broker needs. Common grades for this division are Impurity reference standard with characterisation data, Secondary / working standard, Stable-isotope labelled standard and Nitrosamine (NDSRI) standard.

Pharma compliance in Nepal
| Authority | DDA (Department of Drug Administration) |
|---|---|
| Seaports | Birgunj ICD (via Raxaul, road/rail), Kolkata/Haldia (for third-country cargo) |
| Airports | Kathmandu Tribhuvan (KTM) |
| Dangerous goods | IMDG by sea, IATA DGR by air |
Imports of APIs and pharmaceutical raw materials need a recommendation from the Department of Drug Administration (DDA), and some chemicals require approval from the relevant ministry. Most cargo from India enters by road through Raxaul–Birgunj and is cleared on a customs declaration by a Nepali agent, so a road consignment note and transit papers are part of the set. The India–Nepal Treaty of Trade gives preferential access to many Indian goods, and SAFTA may also apply. Dangerous goods must be packed and labelled for road transport.
From order to delivery
- 1–2 daysQuote and document set agreed
Price, pack sizes, Incoterm and the paperwork list are confirmed in writing.
- 3–7 daysPacking for export
Stock items are packed in UN-rated drums or cartons. Made-to-order material adds its own lead time.
- 1–3 daysExport clearance at Nhava Sheva or Mundra
Shipping bill filed, dangerous goods declared under IMDG where needed.
- 6–10 daysOcean transit to Birgunj ICD (via Raxaul, road/rail)
Port-to-port time depends on the vessel schedule and any transhipment.
- 2–5 daysImport clearance
Your broker clears the goods against local rules. Chemical oversight: Department of Environment / Ministry of Industry.
Indicative total by sea: 13–27 days
By air: about 6–14 days in total.

Questions
Impurity Reference Standards for Nepal
Can Zemixal deliver impurity reference standards to Nepal?
Yes. We ship by sea to Birgunj ICD (via Raxaul, road/rail) and Kolkata/Haldia (for third-country cargo), by air cargo or by express courier depending on quantity and urgency. Every lot carries a COA and a 16-section GHS SDS.
Which documents come with a impurity standards shipment to Nepal?
Commercial invoice, packing list, certificate of analysis and SDS as standard, plus the bill of lading or air waybill and a certificate of origin. Anything specific to DDA (Department of Drug Administration) is agreed with you at quote stage.
How long does delivery to Nepal take?
Allow 6–10 days for ocean transit or 2–4 days by air, plus packing, export clearance and import clearance. The timeline on this page shows each stage.
How is the purity of an impurity standard determined?
Purity is usually assigned by HPLC area percentage, supported by structural confirmation from NMR and mass spectrometry. Where needed, water content, residual solvents or a mass balance approach are added. The methods used and the results for your lot are listed on the certificate of analysis that comes with the vial.
Can I use your impurity standards in place of official pharmacopoeial references?
Our standards are secondary or research materials, not official pharmacopoeial references. Many laboratories use them for method development, peak identification and routine testing, and keep official references for disputes or regulatory submissions where these are mandated. Your quality system and regulator decide which reference is acceptable for each test.
