Tin box

The most common material is tinplate (electrolytic tin-coated steel). You should specify the thickness, typically ranging from 0.21mm to 0.28mm depending on the box size and required durability. For food-grade applications, ensure the material is BPA-free and features a food-safe internal lacquer (gold or clear) to prevent corrosion from moisture or acidic contents.

Request samples that demonstrate CMYK 4-color offset printing or Pantone (PMS) matching for brand consistency. Evaluate the quality of the protective varnish (glossy, matte, or spot UV) and check for embossing or debossing precision. High-quality suppliers on Made-in-China.com should provide a print-proof to ensure alignment and color accuracy before mass production.

For the US market, products must comply with FDA 21 CFR 175.300 and CPSIA (lead and phthalate limits). For the EU, they must meet EC No. 1935/2004 and LFGB standards for food contact materials. Always ask for SGS or Intertek test reports to verify that the inks and coatings are non-toxic and heavy-metal free.

Consider the lid type (slip lid, hinged lid, or lever lid) and the seaming method (rolled-in vs. rolled-out edges). Airtightness is critical for tea or coffee, requiring a silicon or plastic gasket. Tooling costs are a major factor; choosing existing molds can save you $1,500–$3,000 in development fees if your dimensions are flexible.

Tin boxes are prone to denting and scratching. Ensure the supplier uses individual polybags for each unit and double-walled corrugated export cartons. For bulk shipments, insist on palletization with corner protectors and stretch wrapping to prevent movement and moisture ingress during sea freight.

Focus on the Total Cost of Ownership (TCO). Negotiate based on volume tiers; increasing an order from 3,000 to 10,000 units can often reduce the unit price by 15-25%. Additionally, negotiate for free spare units (usually 0.5-1%) to cover potential minor defects or transit damage, and use Made-in-China.com's Secured Trading Service to protect your payment.

Confirm the supplier's daily output capacity and whether they perform in-house printing. Outsourced printing can lead to longer lead times and quality inconsistencies. A standard lead time is 25–35 days after sample approval. Always clarify the Peak Season (e.g., pre-Lunar New Year) schedules to avoid shipping delays.

Check the HS Code (typically 731021 or 731029) for your specific country to determine import duties. Be aware of anti-dumping duties that some regions apply to Chinese steel products. Working with a Verified Supplier on Made-in-China.com ensures you receive the correct Certificate of Origin, which may help in claiming preferential tariff rates under specific trade agreements.
