Seaports	Cotonou, Lomé (Togo, alternative gateway)

Dangerous goods	IMDG by sea, IATA DGR by air

Sea shipments generally need an electronic cargo tracking note (ECTN/BESC), and some imports may fall under verification programmes, so confirm current rules with the importer. APIs and pharmaceutical products fall under ABMed, the national medicines agency. Hazardous chemicals may require environmental clearance from ABE. If cargo landed at Cotonou is moving on to Niger, Burkina Faso or Nigeria, tell us at quotation stage, as transit affects the consignee, routing and documents. Dangerous goods follow IMDG or IATA rules.

Questions

Impurity Reference Standards for Benin

Can Zemixal deliver impurity reference standards to Benin?

Yes. We ship by sea to Cotonou and Lomé (Togo, alternative gateway), 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 Benin?

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 ABMed (Agence Béninoise du Médicament et des autres produits de santé) is agreed with you at quote stage.

How long does delivery to Benin take?

Allow 26–36 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.
