Our HY5 is approved for Europe and Asia, we are working on the approvals for North and South America.
The approval for the US is primarily for the marketing, so the sale of the HY5 in the US necessary. That is, the seat we have will be adapted for the American market because the requirements of the two approvals are quite different.
From a legal point of view, as a manufacturer we can not recommend the use of a European certified seat. Whether the European safety standard is sufficient for use in the US, parents have to decide for themselves. The use of a Top Tether is common in America, as this originally comes from the USA.
