Import Tips

• Provide cross-sectional diagrams and durometer hardness specs to distinguish from plastic seals in Chapter 39

• Ensure FDA compliance if for food-related HVAC; otherwise, standard rubber import rules apply

• Bundle with installation instructions to demonstrate non-specific machinery use, avoiding Chapter 84
