A Guide to "Foreign Trade Clearance" for Winter Thermal Underwear

As a seasoned foreign trade professional with 20 years of import and export experience, I am often asked, "What kind of thermal underwear is truly a good product?" Today, let me guide you through the maze of selecting thermal underwear and offer expert advice from a foreign trade perspective.

Customs Standard: The "Clearance Documents" for Thermal Underwear

in theImport and Export TradeIn our selection process, we prioritize product standards above all else. Just as customs inspections require complete documentation, when choosing thermal underwear, the first thing to check is its "clearance paperwork" — the product label.

• 9. FZ/T73022-201910.: Thermal retention rate ≥30% to qualify
• 11. FZ/T73016-202012.: Higher requirements for wadding type, thermal retention rate ≥45%
• 13. FZ/T73036-2010: The "ID card" of moisture-absorbing and heat-generating underwear
• 15. GB/T30127-201316.: Authoritative certification for far-infrared performance

I remember last year when we exported a batch of thermal underwear to Northern Europe, we almost had them returned due to these standard differences. So when making a purchase, be sure to identify these "clearance codes"!

Fabric composition: The "certificate of origin" for thermal underwear.

In the foreign trade industry, we often say, "Ingredients determine quality." The fabric of thermal underwear is like the product's "certificate of origin," directly determining its thermal performance.

19. Based on my experience, the thermal effectiveness ranking of common fabrics is as follows:

• 20. German fleece fabric21.: Modified acrylic fiber, best thermal performance
• 22. Cashmere23.: The warmth champion among natural materials
• 24. Acrylic25.: Cost-effective choice, warmth close to wool
• 26. Modal/Cotton27.: Moisture-absorbing and breathable but average warmth

28. Interestingly, last year we imported a batch of German fleece thermal underwear that sold exceptionally well in Europe, precisely because its special fiber structure creates a thermal air layer.

Purchasing Tips: The "Inspection Process" from Foreign Trade Experts

In import and export operations, we have a rigorous inspection process. When purchasing thermal underwear, you can also refer to this "foreign trade inspection method":

1. Hand feel test

30. Like our inspection process, first knead the fabric by hand. Quality thermal underwear should:

• 31. Feel soft and non-irritating
• 32. Have fine fuzz on the surface
• 33. Resist pilling after rubbing

2. Elasticity test

34. Stretch horizontally and vertically to observe elasticity. Good thermal underwear should:

• 35. Quickly return to original shape after stretching
• 36. Not develop permanent deformation
• 37. Feel unrestrictive when worn

3. Static electricity test

38. Test static electricity with tissue paper fragments. This is our common export inspection method:

• 39. Rub fabric then approach paper fragments
• 40. Be cautious with products showing excessive static electricity
• Consider adding products blended with natural fibers

Brand Selection: Seeking Trust Like "Long-Term Foreign Trade Partners"

In the foreign trade industry, we value long-term "repeat customers" the most. When choosing thermal underwear, we should also look for such "established brands":

• Professional production history: At least 5 years of thermal underwear production experience
• Complete certifications: Passed international quality system certifications like ISO
• Export records: Brands exporting to cold climate countries are more reliable
• R&D capability: Possesses its own fabric R&D laboratory

I remember a Zhejiang company we collaborated with - their thermal underwear has been exported to Russia for 8 consecutive years due to superior quality, which is the best proof of quality.

Special Reminder: The "Trade Barrier" of Thermal Underwear

Just as there are various technical barriers in international trade, the thermal underwear market also has some "consumption barriers" that need to be wary of:

• False advertising: "Fever" and "far-infrared" functions without test reports
• Ingredient fraud: Exaggerated cashmere content labeling
• Standard confusion: Using ordinary knitting standards to impersonate thermal underwear standards
• Price traps: Extremely low-priced products often cut corners

Last year, we encountered a batch of imported thermal underwear that claimed to be "German technology," but actual testing revealed that its far-infrared performance didn't meet the standards at all. So, you must keep your eyes peeled!

6. Foreign trade experts checklist for selecting thermal underwear

Based on 20 years of foreign trade experience, Ive compiled a professional purchasing checklist:

• ? Look for FZ/T73022 or FZ/T73016 standards
• ? Choose fabrics like Modal, cashmere or high-quality acrylic
• ? Soft texture with fine fleece
• ? Good elasticity without restriction
• ? Minimal static electricity
• ? Choose brands with export experience
• ? Beware of functional claims without test reports
• ? Avoid products with unclear ingredient labeling

Remember, good thermal underwear is like a successful foreign trade order—it requires careful consideration from multiple angles to achieve the "perfect deal." May this guide help you find the most suitable "warm companion" for this winter!
