Ensure that all personnel involved in handling the materials are trained in proper safety procedures. Provide personal protective equipment (PPE) and follow all safety guidelines. Have emergency response plans in place in case of accidents or spills.
Case Study: Building a Compliant Import Process for Electrolyte and Separator Materials
Project Background: A lithium battery cell manufacturer was expanding production and began importing electrolyte and separator materials from overseas suppliers for the first time — around 12,000 kg of electrolyte and 150,000 m² of separator per month. The initial imports were chaotic: the first electrolyte shipment was held at customs for two weeks over dangerous-goods documentation, one separator lot arrived without the required material certificates and was quarantined for a month, and the plant’s incoming inspection found the imported materials behaved differently from the domestic ones — formation results shifted, forcing rework of an entire batch. Management realized they had a process gap: they were importing materials without a plan for regulations, documentation, or incoming verification.
What Happened: We helped the plant build an end-to-end import process. First, regulatory mapping: each material was classified under its correct HS code and dangerous-goods rules — electrolyte as UN-regulated hazardous material (requiring SDS, UN packaging certificates, and a licensed broker), separator as non-hazardous but requiring certificates of analysis and material certifications from the supplier. Second, supplier documentation requirements: every shipment now ships with a standardized document package verified before dispatch, including certificates of analysis per lot. Third, incoming verification: each imported lot is now tested on arrival — electrolyte viscosity and moisture, separator thickness and porosity — against agreed acceptance limits before it’s released to production, so out-of-spec material is caught before it reaches the coating line.
Result: Within three months, customs clearance time was cut from an average of 12 days to 5, and the dangerous-goods holds and documentation quarantines were eliminated. More importantly, incoming verification caught two off-spec separator lots early — before they could shift formation results — and the acceptance limits were written into the supplier contracts. The plant’s import-to-production lead time stabilized at around 20 days from dispatch to release, inventory levels were reduced by a third, and the process — regulatory mapping, supplier documentation, and incoming testing — is now the standard template for importing every new material category as production scales.
