What is HYSF’s “Import Substitution” strategy?

HYSF’s mission includes Import Substitution: successfully challenging international monopolies by providing high-performance domestic alternatives to global brands. We aim to offer products that match global standards at a more competitive cost.

Many subsea projects are constrained by the high cost and long lead times of imported brands.

  • The Goal: HYSF aims to replace these expensive imports with locally manufactured, high-quality equivalents.
  • The Method: Through independent technological innovation, we have developed connectors that feature full interface interchangeability with global brands.
  • The Benefit: This provides our clients with “Marine-grade alternatives” that reduce project budgets without compromising on 60MPa depth performance.
