Import Tips
• Include detailed chemical analysis and mechanical test certificates to substantiate alloy steel classification
• Measure and document wall thickness precisely; values ≥12.7mm shift to different statistical suffix
• Check country-of-origin rules as certain alloy casing faces additional Section 232 tariffs
