Pharma compliance in Taiwan

Authority	TFDA
Seaports	Kaohsiung, Keelung, Taichung
Airports	Taipei Taoyuan (TPE), Kaohsiung (KHH)
Dangerous goods	IMDG by sea, IATA DGR by air

Under the Toxic and Concerned Chemical Substances Control Act (TCSCA), administered by the Ministry of Environment, new and certain existing chemical substances must be registered, and listed toxic or concerned substances need permits or approvals before import. The Ministry of Labor runs a parallel registration scheme under the Occupational Safety and Health Act. Traditional Chinese SDS and labels are expected and are usually prepared by the importer. APIs need TFDA registration and DMF review. Dangerous goods follow IMDG or IATA rules.

Questions

Impurity Reference Standards for Taiwan

Can Zemixal deliver impurity reference standards to Taiwan?

Yes. We ship by sea to Kaohsiung and Keelung, 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 Taiwan?

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 TFDA is agreed with you at quote stage.

How long does delivery to Taiwan take?

Allow 16–24 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.
