The Real Pain Points Holding Your LSR Projects Back
1. Sky‑rocketing material costs. 2024 data shows LSR prices up 12 % YoY, squeezing margins for OEMs.
2. Inconsistent quality. 38 % of purchasers report batch‑to‑batch variation that leads to re‑work and delayed product launches.
3. Lengthy lead times. Typical Asian suppliers quote 45‑60 days; your market demands ≤15 days to stay competitive.
4. Complex compliance landscape. CE, FDA, RoHS, ISO 9001, and regional customs rules add hidden costs.
5. Shipping & logistics headaches. Freight from China often exceeds $2,500 per container for 1 ton LSR, eroding ROI.
