The Pain Points Keeping Your Supply Chain Stuck

In 2024‑2025, 30% of global LSR purchasers reported at least one of the following issues (source: Grand View Research):

  • High Unit Price – Average LSR grade A price in the US rose to $4.20/kg, 12% above 2022 levels.
  • Inconsistent Quality – 18% of OEMs cite batch‑to‑batch variation in hardness (Shore A 45‑55) leading to re‑work.
  • Slow Lead Times – Typical delivery from China >45 days, causing production bottlenecks.
  • Expensive Shipping & Customs – Freight surcharges add $0.80‑$1.10 per kg.
  • Lack of Technical Support – 65% of buyers say suppliers cannot help with mold design or material selection.

These constraints directly hit your ROI: higher inventory, missed launch windows, and reduced competitiveness. What if you could cut cost, improve quality, and receive parts within 14 days?
