Supplying impurity reference standards to Bangladesh

By sea, containers and LCL lots take roughly 14–21 days to Chattogram (Chittagong) and Mongla. Air cargo to Dhaka Hazrat Shahjalal (DAC) takes 2–4 days, which suits small and urgent packs. The relevant authority is DGDA (Directorate General of Drug Administration). Our export desk lines up the COA, GHS SDS and shipping documents to match. Common grades for this division are Impurity reference standard with characterisation data, Secondary / working standard, Stable-isotope labelled standard and Nitrosamine (NDSRI) standard.

Dangerous goods	IMDG by sea, IATA DGR by air

Importers need an Import Registration Certificate and normally open a letter of credit through their bank. APIs and pharmaceutical raw materials must be approved by the DGDA, often through an approved raw-material list. Flammable solvents need licences from the Department of Explosives, and precursor chemicals require clearance from the Department of Narcotics Control. Goods of Indian origin can claim SAFTA or APTA preferences with the right certificate of origin. Dangerous goods follow IMDG or IATA rules.

Questions

Impurity Reference Standards for Bangladesh

Do you ship impurity standards to Bangladesh?

Yes. We ship by sea to Chattogram (Chittagong) and Mongla, 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 Bangladesh?

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 DGDA (Directorate General of Drug Administration) is agreed with you at quote stage.

How long does delivery to Bangladesh take?

Allow 14–21 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.
