HS Code for PLA resin

Poly(lactic acid), commonly known as PLA resin, is classified under HS code 3907.70. This classification is governed by the General Rules for the Interpretation of the Harmonized System (GRI), specifically GRI 1 and 6. Chapter 39 covers plastics and articles thereof, and heading 3907 is designated for polyacetals, other polyethers, epoxide resins, polycarbonates, alkyd resins, polyallyl esters, and other polyesters in primary forms. As a thermoplastic aliphatic polyester derived from renewable resources like corn starch or sugarcane, PLA fits the chemical definition of a polyester. The specific subheading 3907.70 was created to distinguish PLA from petroleum-based polyesters for environmental and statistical tracking. According to Chapter 39 Note 6, 'primary forms' refers to liquids, pastes, dispersions, granules, flakes, and powders. Therefore, PLA in pelletized form for 3D printing filament production or injection molding is correctly placed here. The classification remains consistent regardless of whether the resin is virgin or recycled, provided it remains in a primary form and has not been worked into a specific shape.

Products Included

• PLA pellets for injection molding
• PLA granules for extrusion
• Biodegradable PLA resin beads
• PLA powder for industrial applications
• Liquid PLA dispersions

Common Misclassification

PLA resin is frequently misclassified under HS code 3913.90, which covers other natural polymers. While PLA is bio-based, it is a chemically synthesized polymer and must stay within 3907. Another common error is using 3907.99, the residual category for 'other' polyesters. Since the 2017 HS nomenclature update, 3907.70 is the mandatory specific code for PLA. Additionally, 3D printing filament is often confused with resin; however, filament is a semi-finished product and usually falls under 3916.90 or 3926.90 depending on its shape and retail packaging.

FAQ

What is the HS code for PLA resin?

The HS code for PLA resin in primary forms, such as pellets or granules, is 3907.70.

Is PLA resin classified as a natural polymer?

No, although derived from natural sources, PLA is a product of chemical synthesis and is classified as a polyester under heading 3907, not as a natural polymer under heading 3913.
