📌 Part I: Product Definition & Classification: Do You Really Understand "Other Square Timber"?

"Square timber" in international trade context usually refers to wood that has been sawn, chipped lengthwise, sliced, or peeled, often planed, sanded, or end-joined, with a thickness exceeding 6 mm. It is categorized based on:

1. Wood Species:
2. Coniferous (Softwood): Such as pine, spruce, fir, etc.
3. Non-coniferous (Hardwood): Such as oak, maple, walnut, etc.
4. Processing State:
5. Untreated: Naturally dried or kiln-dried, no chemical treatment.
6. Treated: Preserved, fireproofed, etc.
7. Shape/Size:
8. Square/Rectangular: With uniform cross-sections.

⚠️ Key Distinction Point:
- If it is coniferous and other (not specified as planks, beams, etc.), it may fall under 4407.19.00.93.
- If it is non-coniferous and other, it may fall under 4407.99.02.95.
- Both types must have a thickness > 6 mm to qualify for these HS codes.
