HS Code for Polylactic acid

Polylactic acid (PLA) is classified under HS code 3907.70 as a polyester in primary form. Heading 3907 encompasses various polymers, including polyacetals and polyesters. PLA is a biodegradable thermoplastic aliphatic polyester derived from renewable resources like corn starch or sugarcane. Under the Harmonized System, primary forms are defined as liquids and pastes, including dispersions and solutions, or blocks of irregular shape, lumps, powders, granules, flakes, and similar bulk forms. As a specific type of polyester, PLA was granted its own subheading (3907.70) to facilitate better tracking of bio-based plastics in international trade. The classification is straightforward for the raw resin; however, once the PLA is processed into finished goods like cups, cutlery, or 3D printer filaments, the classification moves to other headings within Chapter 39 or elsewhere depending on the final product's function. The inclusion of PLA in 3907 reflects its chemical nature as a poly(lactic acid) polymer, regardless of its biodegradable properties, which are not a primary factor for heading-level classification in Chapter 39.

Common Misclassification

PLA is often misclassified under 3913.90, which covers "other" natural polymers. While PLA is bio-derived, it is a synthetic polymer produced through the polymerization of lactic acid, placing it firmly in 3907. Another common error is using 3920.99 for PLA film; while 3920 is for sheets/films, the primary resin must stay in 3907.70. Furthermore, 3D printing filaments made of PLA are frequently misclassified here, but they should actually be under 3916.90 as monofilaments with a cross-sectional dimension exceeding 1mm. Misunderstanding the difference between a natural polymer and a synthetic polymer from natural sources is the main cause of error.

FAQ

What is the HS code for Polylactic acid?

The HS code for Polylactic acid (PLA) in primary forms is 3907.70.

Is PLA considered a natural polymer for customs?

No, for customs purposes, PLA is considered a synthetic polymer because it is produced through chemical polymerization, even though the monomer is derived from natural sources.
