How it is structured
3917.40 is a six-digit subheading. Its first two digits, 39, are the chapter; the first four, 3917, are heading 39.17; the last two, 40, identify the subheading within the heading.
Countries add their own digits after these six for their national tariff lines.
- Chapter 39
- Plastics and articles thereof
- Heading 39.17
- Tubes, pipes and hoses, and fittings therefor (for example, joints, elbows, flanges), of plastics
- Subheading 3917.40
- Fittings
In other countries
No national tariff lines under 3917.40 are live on border.bot yet. Tariffs built on the Harmonized System (HS2022) use 3917.40 at six digits and add their own digits after it.
