HS Code for Enzymes
TL;DR: Enzymes classify under **HS 3507** in the 2025 HS codes guide. Key updates include GCC 12-digit expansions, EU CN revisions, and US HTS mandates for tariff compliance.
What Is the HS Code for Enzymes in 2025?
HS codes classify goods for international trade. **The primary HS code for enzymes remains 3507** across global systems, with national extensions for 2025 tariff compliance.
- Chapter 35 covers albuminoidal substances and enzymes
- Heading 3507 specifically targets enzymes
- 6-digit standard, plus country-specific digits
- Updated annually by World Customs Organization (WCO)
- No major WCO revision until 2027
HS 3507 Breakdown: Subcodes for Enzymes
**Enzymes accelerate chemical reactions as biological catalysts.** In HS classification, HS 3507 organizes them by type and preparation.
| HS Code | Description | Examples | 2025 Notes |
|---|
| 3507.10 | Rennet and concentrates | Cheese production enzymes | Unchanged |
| 3507.90 | Other enzymes, prepared | Industrial, food-grade | Biotech focus in EU CN |
| 3507.90.90 | Not elsewhere specified | Microbial enzymes | GCC 12-digit detail |

2025 HS Code Changes Impacting Enzymes Classification
**Regional updates reshape enzymes HS code application in 2025.** National changes drive tariff compliance needs.
- GCC 12-digit HS codes 2025 start Jan 1 for precision
- US mandatory HTS from Sep 1 for all imports
- EU Combined Nomenclature 2025 refines Chapter 35
- US de minimis ends Aug 29, raising low-value scrutiny
- China and ASEAN align with WCO notes
How to Find the Correct HS Code for Enzymes: 2025 Guide
**Use this step-by-step process for accurate enzymes classification.** Ensures tariff compliance 2025.
- Determine enzyme function (e.g., hydrolases, oxidoreductases)
- Locate Chapter 35, Heading 3507 in WCO HS
- Match subheading (3507.10 or 3507.90)
- Add national digits (e.g., US 10-digit HTS)
- Verify with official tools like EU TARIC
- Consult for mixtures or novel biotech products
GCC 12-Digit HS Codes 2025 for Enzymes
**GCC nations expand to 12 digits January 1, 2025.** Affects enzymes imports into Saudi Arabia, UAE, and others.
- Enhanced specificity for biotech enzymes
- Impacts tariff rates and documentation
- Requires precise HS 3507 sub-classification
- Aligns with GCC Common Customs Tariff
- 2025 case study: Biotech firm saved 15% duties via accurate coding
US HTS Codes for Enzymes in 2025
**US enforces 10-digit HTS mandatory from September 2025.** Critical for enzyme shipments post-de minimis closure.
| US HTS | Enzyme Type | Duty Rate 2025 |
|---|
| 3507.10.5000 | Rennet | Variable |
| 3507.90.6500 | Industrial enzymes | 3.5% |
| 3507.90.9500 | Other | Check HTS |
Challenges in Enzymes HS Code Classification 2025
**Complexities arise from innovations and mixtures.** Biotech advances test HS 3507 boundaries.
- Enzyme-substance blends (principal function rules)
- New genetically engineered variants
- Regional tariff discrepancies
- Cold chain documentation ties to HS accuracy
- Penalties for misclassification up to 300% duties
