--- title: My Taiwan Client Asked Me for PIF Materials, What Should I Prepare author: Pharmacist Hsiao-Chen lang: en canonical: https://www.pharmachen.com/pif/en/maker/taiwan-client-asks-pif/ published: 2026-08-25 --- # My Taiwan Client Asked Me for PIF Materials, What Should I Prepare **Bottom lineļ¼š** Under Taiwan's PIF system, legal responsibility lies with the Taiwan importer; as an overseas maker, you are the supporting data provider. The key material to prepare is one complete ingredient list with concentration ratios. ## Understand your position first From July 1, 2026, general cosmetics cannot be sold in Taiwan without a PIF. Your Taiwan importer client must comply and is therefore requesting materials from you. Crucially, legal responsibility lies with the Taiwan importer; you are the supporting party. You need not become a Taiwan regulatory expert. ## What to provide The most important is the complete ingredient list with each ingredient's concentration ratio, data you already have from manufacturing. Once provided, the Taiwan-side professional process takes over the remaining physicochemical properties, toxicological support, and safety assessment. You needn't research Taiwan formats or toxicological data. ## What happens if you don't cooperate The Taiwan importer cannot complete the PIF, and your product cannot be sold or displayed in Taiwan, meaning it may disappear from the Taiwan market. A smooth Taiwan business could halt over a single document. ## FAQ ### For Taiwan's PIF, what should I as an overseas maker do? You are the supporting data provider. Most importantly, provide the complete ingredient list with concentration ratios; you need not become a Taiwan regulatory expert. ### Does legal responsibility lie with me (the manufacturer)? No. PIF legal responsibility lies with the Taiwan importer; you are the supporting data provider. ### Besides the ingredient list, what else might be requested? Manufacturing method, quality specifications, GMP certificate, and stability testing, if available, speed up the Taiwan-side work, but the key starting material is the ingredient list and ratios. ### What happens to the business if I don't cooperate? The Taiwan importer cannot complete the PIF, and the product may not be sold in Taiwan. Continuing the business requires cooperating on data. --- https://www.pharmachen.com/pif/en/maker/taiwan-client-asks-pif/
