1. Introduction: Why QA Matters in the Cassia Trade

Square cut cassia is a high-demand format for food, tea, and pharmaceutical industries. But without proper QA, buyers risk importing shipments that fail lab testing, clog production lines, or get rejected at customs.

Here are the top 10 QA parameters professional buyers should monitor when sourcing square cut cassia.

2. Parameter #1: Volatile Oil Content (≥2.5%)

The aroma strength of cassia is directly tied to cinnamaldehyde oil. Buyers should request:

• COA with GC-MS or steam distillation results
• Minimum threshold of 2.5% volatile oil (VO), ideally above 3%

Why it matters: Higher VO ensures stronger scent and flavor delivery in food and beverage applications.

3. Parameter #2: Moisture Level (≤12%)

Too much moisture can trigger:

• Mold growth
• Shipment rejections at port
• Shortened shelf life

Acceptable range: 10%–12%. Confirm with lab moisture analysis.

4. Parameter #3: Cut Size Consistency

Uniform square cuts (typically 2–4 cm or 3–6 cm):

• Enhance visual appeal
• Allow better batching
• Improve blending and infusion performance

Avoid inconsistent sizing with bark shards or oversized fragments.

5. Parameter #4: Bark Cleanliness and Surface Color

Look for:

• Cinnamon-brown to dark tan color
• No grey or black discoloration
• Dust-free surfaces with visible bark grain

Color inconsistencies often indicate improper drying or poor handling.

6. Parameter #5: Bark Thickness (0.3–0.5 cm)

Ideal bark thickness ensures:

• Sturdy form for shipping and stacking
• Predictable infusion release
• Compatibility with industrial grinders

Too thin = fragile. Too thick = inefficient flavor release.

7. Parameter #6: Absence of Foreign Matter

Premium square cut cassia must be free from:

• Stones or soil
• Plastic threads
• Insect parts or rodent contamination

This is critical for F&B compliance and consumer safety.

8. Parameter #7: Aroma Intensity and Clarity

Perform a quick aroma check:

• Clean, sharp cinnamon smell
• No musty or smoky aftertones

Aroma testing can reveal issues like high humidity drying, low VO, or poor raw material sourcing.

9. Parameter #8: Packaging Quality for Export

Export-ready cassia should be packed in:

• PE-lined kraft or carton boxes (10kg or 20kg)
• Sealed with moisture-proof liners
• Clearly labeled with batch info and net weight

Proper packaging helps maintain integrity over long transit.

10. Parameter #9: Certification Support (COA, HACCP, Organic)

A verified supplier should provide:

• Full COA with oil and moisture content
• HACCP and Organic documentation if applicable
• Phytosanitary and fumigation certificates

Always request these before PO confirmation.

11. Parameter #10: Batch Traceability and Labelling

Every box of cassia should have:

• Printed batch number
• Size grade (2–4 cm, 3–6 cm)
• Origin and export info

Why it matters: Supports recall traceability, customs clearance, and warehouse tracking.

12. Final Checklist for Importers

Before confirming a cassia shipment:

• ✅ Request lab reports for VO and moisture
• ✅ Ask for real product photos and cut specs
• ✅ Confirm certifications and shipping labels
• ✅ Verify packaging format and net weight

This checklist helps reduce shipment risks and builds importer confidence.
