Supplying impurity reference standards to Thailand

By sea, containers and LCL lots take roughly 12–18 days to Laem Chabang and Bangkok (Khlong Toei). Air cargo to Bangkok Suvarnabhumi (BKK) takes 2–4 days, which suits small and urgent packs. The relevant authority is Thai FDA. 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.

Industrial chemicals listed under the Hazardous Substance Act B.E. 2535 are regulated mainly by the Department of Industrial Works. Type 2 substances need notification and Type 3 substances an import licence held by the Thai importer. Thai FDA controls APIs, medicines and certain household and precursor chemicals, while narcotics precursors fall under ONCB. Check which category your product falls into before ordering. Dangerous goods follow IMDG or IATA rules. AITIGA or Early Harvest Scheme preference requires a proper certificate of origin.

Questions

Impurity Reference Standards for Thailand

Do you ship impurity standards to Thailand?

Yes. We ship by sea to Laem Chabang and Bangkok (Khlong Toei), 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 Thailand?

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 Thai FDA is agreed with you at quote stage.

How long does delivery to Thailand take?

Allow 12–18 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.
