Pharma compliance in United Kingdom

Dangerous goods	IMDG by sea, IATA DGR by air

Great Britain operates UK REACH under HSE. Substances imported at 1 tonne or more per year need registration by a GB-based importer or a UK Only Representative, and labelling follows GB CLP. Northern Ireland still applies EU REACH. APIs for UK medicines must meet GMP and MHRA import requirements, including written confirmation for Indian-origin active substances. Dangerous goods travel under IMDG or IATA rules, and India–UK CETA preferences will depend on valid origin documents once the agreement is in force.

Questions

Impurity Reference Standards for United Kingdom

Do you ship impurity standards to United Kingdom?

Yes. We ship by sea to Felixstowe and Southampton, 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 United Kingdom?

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 MHRA is agreed with you at quote stage.

How long does delivery to United Kingdom take?

Allow 22–30 days for ocean transit or 3–5 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.
