Importing aluminum strip for transformer winding can be profitable, but many buyers—especially new importers—face issues that cause delays, financial losses, or production problems. Here are the top five mistakes you should avoid when sourcing aluminum strip globally.

Unclear Specifications

The most common mistake is providing incomplete or vague technical specifications. Always confirm:

• Alloy grade (e.g., 1060, 1050, 1070)
• Temper (usually O, soft)
• Thickness and width range
• Edge condition (slit, rounded, or deburred)
• Core ID (150mm or 300mm)

Ignoring Certifications

Many importers forget to request essential documents like:

• Mill Test Certificate (MTC)
• Certificate of Origin (especially Form E for ASEAN)
• RoHS/REACH declarations (mandatory in Europe)

Missing these can lead to customs issues and fines.

Choosing Price Over Quality

Low prices often come with hidden risks: recycled aluminum, poor annealing, or incorrect alloy. Choose verified suppliers with factory audits and testing capabilities. Saving $50/ton is not worth a rejected batch at your factory.

Underestimating Lead Time

Transformer aluminum strip is often made-to-order. Production takes 7–15 days, plus shipping. Plan ahead to avoid project delays or air freight premiums.

Poor Packaging & Handling Instructions

Improper packaging causes coil damage during transit. Always confirm:

• Waterproof inner wrap
• Edge protection
• Steel or wooden pallet base
• Shipping marks and weight labeling

Bonus Tip: Know Your HS Code

Always declare the correct HS code: 7606.12.00 for aluminum strip, not sheet or foil. Misclassification can result in extra duty or seizure.

With proper planning, importing transformer aluminum strip can be smooth and cost-effective. Avoid these mistakes, and work with experienced exporters who understand your industry and product needs.
