HS Code for Acyclic Polycarboxylic Acids

TL;DR: Discover the exact HS code for acyclic polycarboxylic acids (2917.19) in 2025, including key updates for US HTS, GCC 12-digit codes, EU CN changes, and tariff compliance tips for global shipments.

What Is the HS Code for Acyclic Polycarboxylic Acids?

The primary HS code for acyclic polycarboxylic acids is 2917.19 under the 2025 Harmonized System. This 6-digit code classifies these organic chemicals worldwide for customs and tariffs.

  • Chapter 29: Organic chemicals
  • Heading 2917: Polycarboxylic acids
  • Subheading 2917.19: Other acyclic types
  • Extended 12 digits)
  • Valid per WCO HS 2022 through 2027

Accurate use ensures smooth international trade in 2025.

Key Examples of Acyclic Polycarboxylic Acids and Their HS Codes

Acyclic polycarboxylic acids lack ring structures and have multiple carboxyl groups (-COOH). They are vital in manufacturing polymers, pharmaceuticals, and cleaners.

  • Oxalic acid (2917.11): Used in metal polishing and textiles
  • Succinic acid (2917.19): Bio-based plastics and food additives
  • Adipic acid (2917.12): Nylon production precursor
  • Malonic acid (2917.19): Pharmaceutical intermediates
  • Glutaric acid (2917.19): Resins and lubricants

Misclassification risks delays and fines.

HS Code 2917.19 Breakdown for 2025 Shipments

HS code 2917.19 covers 'other' acyclic polycarboxylic acids not specified elsewhere.

2917.11.00Oxalic acidCrystals, solutionsHazmat regulations apply
2917.12.00Adipic acidPure formsEU purity standards

WCO confirms no major changes until 2027.

2025 HS Code Updates Impacting Acyclic Polycarboxylic Acids

National HS code extensions evolve in 2025 despite stable WCO base.

  • US: 10-digit HTS mandatory for all parcels from Sep 2025
  • GCC: 12-digit HS codes rollout Jan 1, 2025 (Saudi Arabia, UAE, etc.)
  • EU: Combined Nomenclature 2025 refines chemical subheadings
  • China: Minor export adjustments for organics
  • UK: Post-Brexit alignment with global standards

These affect duty calculations for chemicals.

Regional HS Code Variations for Acyclic Polycarboxylic Acids in 2025

Countries extend the base HS code 2917.19 for precise tariffs.

RegionBase HS2025 ExtensionKey Change
USA2917.192917.19.1000HTS 10-digit required

EU2917.192917 19 80CN refinements
China2917.192917.19.9000Export stable

Always verify local customs databases.

How to Find the Correct HS Code for Acyclic Polycarboxylic Acids (Step-by-Step)

Use this 2025 guide to classify acyclic polycarboxylic acids accurately.

  1. Identify chemical structure: Confirm acyclic with 2+ -COOH groups
  2. Navigate to Chapter 29, Heading 2917
  3. Select subheading (e.g., 2917.19 for others)
  4. Add country-specific digits (e.g., US HTS)
  5. Cross-check with WCO HS tool or national portal

This prevents compliance issues.

Common Classification Challenges for HS Code 2917.19 in 2025

Mixtures and derivatives complicate HS code assignment for polycarboxylic acids.

  • Pure vs. impure forms
  • Principal ingredient rule for blends
  • Hazmat vs. tariff overlaps
  • Regional digit variations
  • De minimis threshold changes

Consult official rulings for certainty. Sources: WCO Nomenclature.
