🥔 Potato Starch & Derivatives: HS Code Breakdown & US Customs Clearance Guide

🌐 HS Code Reference & Clearance Strategy | 2026 Latest Tariff Analysis | Professional Import Compliance
📌 Part 1: Product Definition & Classification: What Exactly is "Potato Starch"?

"Potato Starch" in international trade covers a range of products derived from potatoes, varying by processing level and physical form. In customs classification, the distinction lies primarily in the physical state (powder vs. processed articles) and the specific processing stage.

1. Raw Starch/Powder: Unmodified potato starch or potato flour, typically fine white powders used in food processing, adhesives, or textiles.
2. Prepared Starch Articles: Products where starch has been further processed, modified, or mixed with other ingredients into a specific form (e.g., flakes, instant mixes, or specific industrial preparations).

⚠️ Key Classification Distinction:
- If the product is pure potato starch or potato flour (raw material state) → Classify under Chapter 11 (Preparations of Cereals, Flour, Starch or Milk; Pastry Products) under headings 1105 or 1108.
- If the product is a prepared article containing starch but not meeting the specific definition of pure starch/flour → Classify under Other preparations (1108.13.00.90).
- Note: Cassava starch (1108.14.00.00) is listed as a reference for similar starch categories but is a different botanical source.

📦 Part 2: HS Code Classification Matrix (2026 Latest Tariff Reference)

🔍 Critical Note:
- 1108.13.00.10 is for pure potato starch or flour.
- 1108.13.00.90 is for processed potato starch articles (not pure starch).
- 1105.10.00.00 and 1105.20.00.00 are specific subheadings for potato flour (finer grind, higher protein/ash content than starch).
- 1108.14.00.00 is for Cassava Starch (Tapioca), often used as a comparator but not potato-derived. Do not confuse the two.

📌 Part 6: Common Errors & Pitfalls (Lessons Learned)

❌ Error 1: Misclassifying Potato Starch as Cassava Starch (1108.14.00.00)
👉 Consequence: Customs audit, penalties, and back-tariff demands. Botanical source must be verified.

❌ Error 2: Failing to Declare Specific Duty
👉 Consequence: Underpayment of duties by $0.0056-$0.017/kg. Customs will issue a bill for the difference + interest.

❌ Error 3: Ignoring FDA Requirements
👉 Consequence: Shipment held at port, potential destruction or re-export if FDA compliance is not met.

❌ Error 4: Vague Description "Starch"
👉 Consequence: Customs may assign a higher default tariff rate or delay clearance for further examination.

✅ Correct Practice:

“Potato Starch (Solanum tuberosum), Pure, Fine Powder, Food Grade, HS 1108.13.00.10, Net Weight: 10,000 kg, Origin: China”

🎯 Part 7: Conclusion: Precision in Classification Saves Money!

🎯 Remember:

🔹 “Potato vs. Cassava, Starch vs. Flour – One digit change, huge cost difference!”
🔹 “35% Surcharge is Real – Budget for it!”
🔹 “FDA Prior Notice is Mandatory – Don’t Get Stuck at the Border!”

📌 Pro Tip:
If your potato starch is sourced from Peru, Canada, or the EU, you may benefit from FTAs (Free Trade Agreements) with the US, potentially reducing or eliminating the 35% surcharge. Always check the origin of production against current US trade agreements.

📞 Engage a licensed customs broker.
📄 Provide COA (Certificate of Analysis) and FDA registration numbers.
🚀 Ensure accurate HS Code declaration to avoid costly delays.
