Import Tips
• Request STR 5L quality certificate from Thai Rubber Association or equivalent to confirm grade compliance
• Package in bales ≤100kg to match standard primary forms; oversized bales may raise questions on processing level
• Avoid mixing with synthetic rubber, as blends may fall under different primary synthetic headings like 4002
