Import Tips
• Include detailed dimensional specs and grade certifications in entry docs; BTC couplings must be documented separately from premium threads
• Common pitfall: misdeclaring weight per foot leading to wrong OD classification
• Comply with API Monogram requirements for U.S. market acceptance
