Codes by variant
| Variant | HTS code | General duty | Est. from China |
|---|---|---|---|
| PLA | 3916.90.30.00 | 6.5% | 19% |
- 3916.90.30.00: Of other plastics / Monofilament
What decides the code
3D printer filament is plastic monofilament with a cross-sectional dimension over 1 mm, classified under heading 3916, PLA under 3916.90.30.00.
- Cross-sectional dimension over 1 mm puts the filament in heading 3916 as monofilament rather than in a strip or film heading.
- Material of PLA, a plastic other than polymers of ethylene or vinyl chloride, leads to 3916.90.30.00.
- Filament left not otherwise worked stays in heading 3916, since surface working alone does not move it out.
Common mistakes
- Classifying PLA filament under 3926.90 as other articles of plastics is wrong because heading 3916 covers monofilament by name.
- Using 3916.10 or 3916.20 is wrong because those subheadings cover polymers of ethylene and of vinyl chloride, not PLA.
- Treating filament as strip or film under Chapter 39 film headings is wrong when the cross-sectional dimension exceeds 1 mm.
