Supplying impurity reference standards to Laos

By sea, containers and LCL lots take roughly 18–28 days to Laem Chabang (via road to Vientiane) and Bangkok (via road). Air cargo to Vientiane Wattay (VTE) takes 4–7 days, which suits small and urgent packs. The relevant authority is Food and Drug Department (FDD), Ministry of Health. 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.

Pharma compliance in Laos

Dangerous goods	IMDG by sea, IATA DGR by air

Sea cargo is normally discharged at Laem Chabang or Bangkok and moves by road under Thai transit procedures, so transit documents must be consistent with the bill of lading. Hazardous and controlled chemicals generally need import approval from the Ministry of Industry and Commerce. Medicines and APIs require registration with the Food and Drug Department. Dangerous goods must follow IMDG or IATA rules as well as road dangerous goods rules on the transit leg. AITIGA or APTA preference requires a certificate of origin.

Questions

Impurity Reference Standards for Laos

Do you ship impurity standards to Laos?

Yes. We ship by sea to Laem Chabang (via road to Vientiane) and Bangkok (via road), 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 Laos?

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 Food and Drug Department (FDD), Ministry of Health is agreed with you at quote stage.

How long does delivery to Laos take?

Allow 18–28 days for ocean transit or 4–7 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.
