Raw Flaxseeds

🌿 Raw Flaxseeds (生亚麻籽)

🌐 HS Code Classification & Tariff Guide | 2026 Updated Customs Rules | Expert Clearance Strategy
📌 One Product, Multiple HS Codes — Understand Why & How to Avoid Penalties!

📌 一、Product Definition & Classification: What Exactly Are Raw Flaxseeds?

Raw flaxseeds — also known as linseed — are the whole, unprocessed seeds of the Linum usitatissimum plant. They are rich in omega-3 fatty acids, fiber, and lignans, and are widely used in food, animal feed, and industrial applications (e.g., oil extraction, bio-based materials).

In international trade, raw flaxseeds are classified under two main categories based on their form, use, and intended purpose:

⚠️ Key Insight:
- If intended for oil extraction → classified under 1515.11.00.00 or 1515.19.00.00 (oilseed category)
- If not clearly intended for oil, or no specific use stated → classified under 1207.99.03.91 or 1207.99.03.40 (general oilseeds)

🔍 Critical Rule:
The declared purpose determines the HS code — not just the physical product.
A single shipment of raw flaxseeds can be subject to very different tariffs, depending on how it's described in the commercial invoice.

📦 二、HS Code Breakdown (2026 Updated Tariff Schedule)

✅ All five codes apply to the same physical product: Raw Flaxseeds
❗ But only one should be used per shipment — based on intended use and documentation.

💰 三、2026 Tariff & Duty Breakdown (Detailed Tax Clause Explanation)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: November 10, 2025 (and ongoing)
✅ Legal Basis: Section 301, IEEPA, and Section 122 of the Trade Act

🎯 1. 1515.11.00.00 — Crude Flaxseed Oil & Its Fractions

📌 Why This Applies:
- If the flaxseeds are intended for oil extraction and described as “crude” or “raw oil feedstock”
- This is the most favorable rate among the five codes (lowest total duty)

🎯 2. 1207.99.03.91 — Other Oilseeds (General Classification)

📌 Why This Applies:
- If the purpose is unclear or no oil extraction intent is stated
- Used when the product is not explicitly linked to oil processing
- Highest tariff among all codes — 35% total

🎯 3. 1515.19.00.00 — Flaxseeds as Oil Raw Material

📌 Why This Applies:
- Matches raw material for flaxseed oil — same as 1515.11.00.00
- Used when oil extraction is the primary purpose, even if not labeled "crude oil"

🎯 4. 1207.99.03.40 — Other Oilseeds (No Specific Use)

📌 Why This Applies:
- When no use is declared or purpose is ambiguous
- Common in bulk imports with vague descriptions
- Same rate as 1207.99.03.91 — 35% total duty

🛠️ Four Critical Clearance Tips (Avoid Costly Mistakes!)

✅ 1. Declare the Intended Use — It’s Everything!

🔥 Golden Rule:
- If you're selling to an oil refiner, declare it as “for oil extraction” → Use 1515.11.00.00 or 1515.19.00.00 → 17.5% total
- If you’re selling to a food processor or feed mill, and don’t specify oil use, you’ll be hit with 35% — even if it’s the same product!

📌 Pro Tip:
Add a line on the commercial invoice:

"Intended for industrial oil extraction — not for direct human consumption."

✅ 2. Avoid "General Oilseed" Classifications Unless Necessary

❌ Never use 1207.99.03.91 or 1207.99.03.40 unless you have no alternative
- These are high-risk codes with 35% duty
- They are not for flaxseeds per se — they’re for "other oilseeds" when purpose is unclear

✅ Use 1515.11.00.00 or 1515.19.00.00 if oil use is intended — even if the buyer is a food company

✅ 3. Document Everything — Prove the Purpose

📌 If you don’t have proof of oil use, customs will assume the worst → default to 35% duty.

✅ 4. Use the Correct Product Name in Declarations

❌ Don’t say: “Flaxseeds, raw, for food”
✅ Do say: “Raw Flaxseeds — Feedstock for Crude Flaxseed Oil Production”

🔥 Pro Tip:
Use exact terms from the HTSUS: - “Raw flaxseeds”
- “Flaxseed for oil extraction”
- “Crude flaxseed oil raw material”

✅ This triggers the correct HS code and avoids misclassification.

🌍 Global Market Comparison (2026)

📌 Insight:
- Only the US imposes 301/IEEPA tariffs on Chinese-origin flaxseeds
- Other markets are much more favorable — but only if you declare correctly

🚨 Common Mistakes & Costly Pitfalls (Real Cases)

❌ Mistake 1:

“We shipped 10 tons of raw flaxseeds to the US — no mention of oil use — got 35% duty.”
✅ Fix: Add “intended for oil extraction” in invoice → drop to 17.5%

❌ Mistake 2:

“We used 1207.99.03.91 because it’s “other oilseeds” — it’s generic!”
✅ Fix: 1207.99.03.91 is not for flaxseeds — only for unspecified oilseeds. Use 1515.11.00.00 instead.

❌ Mistake 3:

“We didn’t provide a letter from the buyer — customs delayed shipment.”
✅ Fix: Always attach a buyer’s intent letter for oil use.

🎯 Final Verdict: How to Minimize Tariffs & Ensure Smooth Clearance

🔥 Best Practice:
- Always declare intended use — “for oil extraction”
- Use 1515.11.00.00 or 1515.19.00.00 — avoid 1207.99.03.91/40
- Provide documentation — invoice, spec sheet, buyer letter
- Avoid vague terms like “raw seeds” or “oilseeds” without context

✅ Result:
- Only 6.3¢/kg + 17.5% — not 35%
- Saves thousands per shipment
- Avoids penalties, delays, or rejection

📌 Pro Tips for Exporters & Importers

📞 Apply for an Advance Ruling (Pre-Approval):
- Get official confirmation from U.S. Customs on your HS code before shipment
- Avoid disputes, audits, or retroactive duties

📦 Consider Re-Export to Non-US Markets First:
- Ship to Vietnam/Mexico → process into oil → re-export to US
- Can avoid 301/IEEPA tariffs if origin changes

📊 Track Your Duty Savings:
- 17.5% vs 35% = 17.5% savings per shipment
- For 10-ton shipment at $1.5/kg: $26,250 saved per container

🎯 Conclusion: Precision Beats Guesswork

🔹 Same product, different codes → 20% difference in tariff
🔹 One sentence in the invoice → $26,000 saved
🔹 One wrong code → 35% duty, delay, audit

✅ Remember:

“If it’s for oil — say it. If it’s not — don’t call it ‘other oilseeds.’”
