8E001 “Technology” according to the General Technology Note for the “development” or “production” of equipment or materials, specified by 8A, 8B or 8C.

8E002 Other “technology” as follows:

a. “Technology” for the “development”, “production”, repair, overhaul or refurbishing (re‑machining) of propellers specially designed for underwater noise reduction;

b. “Technology” for the overhaul or refurbishing of equipment specified by 8A001, 8A002.b., 8A002.j., 8A002.o. or 8A002.p;

c. “Technology” according to the General Technology Note for the “development” or “production” of any of the following:

1. Surface‑effect vehicles (fully skirted variety) having all of the following:

a. Maximum design speed, fully loaded, exceeding 30 knots in a significant wave height of 1.25 m or more;

b. Cushion pressure exceeding 3,830 Pa; and

c. Light‑ship‑to‑full‑load displacement ratio of less than 0.70;

2. Surface‑effect vehicles (rigid sidewalls) with a maximum design speed, fully loaded, exceeding 40 knots in a significant wave height of 3.25 m or more;

3. Hydrofoil vessels with active systems for automatically controlling foil systems, with a maximum design speed, fully loaded, of 40 knots or more in a significant wave height of 3.25 m or more; or

4. 'Small waterplane area vessels' having any of the following:

a. Full load displacement exceeding 500 tonnes with a maximum design speed, fully loaded, exceeding 35 knots in a significant wave height of 3.25 m or more; or

b. Full load displacement exceeding 1,500 tonnes with a maximum design speed, fully loaded, exceeding 25 knots in a significant wave height of 4 m or more.

A 'small waterplane area vessel' is defined by the following formula: waterplane area at an operational design draft less than 2x (displaced volume at the operational design draft)2/3.
