In 2026, Chinese customs authorities are enforcing labeling regulations with unprecedented rigor. From food and cosmetics to medical devices and chemical products, a growing number of imported shipments are being detained or rejected solely due to non‑compliant labels. According to GAC enforcement data, over 35% of label‑related rejections involve easily preventable errors such as missing Chinese translations, incorrect ingredient names, or outdated formatting. Understanding the top label mistakes causing customs rejection in 2026 can help importers avoid costly delays, storage fees, and returned goods. This guide analyzes the most frequent labeling failures across different product categories and provides actionable solutions.
1. Missing or Incomplete Chinese Language
The most fundamental requirement across all imported products is that the label must be in simplified Chinese. English‑only or partially translated labels are automatically rejected. Common violations include:
- No Chinese at all: The product bears only the original language label (e.g., English, Japanese, Korean).
- Partial translation: The product name and ingredient list are in Chinese, but warnings, storage instructions, or manufacturer details are left in the foreign language.
- Machine‑translated text: Customs officials can easily spot unnatural phrasing. For example, “For external use only” translated as “仅限外部使用” is correct, but “只供外面使用” is not.
- Missing importer/agent information in Chinese: For imported food, cosmetics, and medical devices, the name and address of the China agent must be in Chinese.
Solution: Engage a professional technical translator for all mandatory label content. Create a bilingual template where Chinese is equally prominent, and have a native Chinese speaker review the translation for natural phrasing.
2. Incorrect Allergen Declaration Under GB 7718-2025
For imported prepackaged foods, the new GB 7718-2025 (effective March 16, 2027, but already enforced for new production in 2026 by many importers) mandates mandatory declaration of eight major allergens. Rejections occur when:
- Allergen present but not declared: A product contains wheat flour or milk powder, but the label does not list “wheat” or “milk” in the ingredient list or separate allergen panel.
- Incorrect allergen name: Using “gluten” instead of the required “cereals containing gluten” or using “shellfish” instead of “crustaceans”.
- Allergen declared but not highlighted: The standard requires that allergens be indicated in bold, underlined, or a separate panel. Plain text without emphasis is non‑compliant.
- Missing one‑to‑one correspondence: The foreign ingredient list includes “soy lecithin”, but the Chinese list omits it. This is a common discrepancy.
Solution: Cross‑reference every ingredient from the original formulation against the eight major allergens. Use a dedicated allergen information panel adjacent to the ingredient list, formatted with bold text or a contrasting background. Ensure that the Chinese ingredient list is a complete translation of the foreign list – no omissions.
3. Font Size Violations (Cosmetics, Medical Devices, Food)
Different product categories have specific minimum font size requirements. The most frequently violated are:
- Cosmetics: Under the Cosmetic Labeling Management Measures, simplified Chinese characters must have a minimum height of 1.8 mm (1.5 mm for packaging area ≤20 cm²).
- Food (GB 7718-2025): Although GB 7718 does not specify a universal minimum, the Food Labeling Supervision Measures require that all mandatory label text be legible. Customs usually applies a 1.8 mm standard as a practical guideline.
- Medical devices: The “Measures for the Administration of Medical Device Instruction Manuals and Labels” (Order No. 6) requires that labels be clearly legible; industry practice adopts 1.8 mm for main text.
Common mistakes: using a font size of 1.2 mm to fit more text, printing on curved surfaces where the effective height is reduced, or using a light‑weight font that is difficult to read even at 1.8 mm.
Solution: Use a ruler or a digital gauge to measure actual printed character height. Choose a bold or regular weight typeface. For small packaging, consider using multiple labels or a fold‑out booklet for the ingredient list (but mandatory warnings must still be on the main label).
4. IECIC Ingredient Name Mismatches for Cosmetics
For imported cosmetics, the ingredient list must use the standardized Chinese names as listed in the Inventory of Existing Cosmetic Ingredients (IECIC). Rejections are common when:
- Using a direct translation of the INCI name instead of the IECIC entry (e.g., “生育酚乙酸酯” vs “维生素E醋酸酯”).
- Omitting the plant part for botanical extracts (e.g., “库拉索芦荟提取物” instead of “库拉索芦荟叶提取物” if the IECIC entry specifies “叶”).
- Using outdated names that were updated in the 2025-2026 IECIC standardization (e.g., older botanical taxonomy).
- Listing ingredients that are not in IECIC at all (unapproved new ingredients) without proper filing.
Solution: Download the latest IECIC database from the NMPA website. Cross‑reference every ingredient. For botanical extracts, use the exact name including the part (leaf, root, seed, etc.) as specified. If an ingredient is not listed, it must be filed as a new cosmetic ingredient before the product can be imported.
5. Missing Mandatory Warnings
Many products require specific warning statements in simplified Chinese. Omission of these warnings is a leading cause of rejection:
- Cosmetics with antibacterial or bacteriostatic claims: Must include “This product is not a drug and does not have therapeutic, nursing or health care effects” (Amendment No. 1 to GB 38598-2020, effective May 1, 2025).
- Melamine tableware: Must state “不可微波加热” (Do not microwave) and “不宜用于盛放热油” (Not suitable for hot oil).
- Foods containing allergens (even if not mandatory): Voluntary cross‑contact warnings such as “May contain traces of nuts” are strongly recommended to reduce liability.
- Medical devices: For Class I devices, the label must include “一次性使用” (single use) if applicable, and “无菌” (sterile) with sterilization method.
- Children‘s products: Toys for children under 36 months must include “Warning: Not suitable for children under 36 months due to small parts”.
Solution: Maintain a regulatory tracking system for all warning requirements relevant to your product category. Update labels immediately when new regulations or amendments take effect.
6. Inconsistent “Dual Date” Format (Food Products)
GB 7718-2025 now requires that labels display both the production date and the shelf‑life expiry date in the format YYYY-MM-DD (e.g., “2026-12-31”). Previously, some products only listed “shelf life: 24 months”. Common violations:
- Using only a production date without an expiry date.
- Using a non‑standard date format (e.g., “31/12/2026” or “December 31, 2026”).
- Printing the expiry date in a coded format that consumers cannot read (e.g., “EXP 26365”).
- Production date missing entirely.
Solution: For all food products, design the label to include a clear “生产日期” (production date) and “保质期至” (expiry date) followed by the date in YYYY-MM-DD format. Use permanent printing (laser or high‑resolution inkjet) to ensure legibility.
7. Prohibited or Unsubstantiated Claims
China’s Advertising Law and product‑specific regulations prohibit certain types of claims. Rejections occur when:
- “Zero added” or similar claims: GB 7718-2025 explicitly bans phrases like “zero added”, “no added”, “no artificial flavors” on food labels. These are considered misleading.
- Health or therapeutic claims for cosmetics: Terms such as “anti‑inflammatory”, “repairs skin barrier”, “treats acne” are not allowed unless the product is a registered special cosmetic (e.g., whitening, sunscreen) with approved claims.
- “Organic” or “natural” without certification: China does not have a legal definition for “organic cosmetics”; such claims may be rejected unless the product is certified under China’s organic certification system (which is rare for imports).
- “Recommended by dermatologists” without evidence: The claim must be supported by test reports, and the evidence must be available for customs inspection.
Solution: Review all marketing claims against the latest regulations. Remove any absolute or comparative superlatives (“best”, “most effective”) unless supported by data. For cosmetic claims, only use efficacy statements that were approved during NMPA registration or filing.
8. Real‑World Case: Cosmetic Label Rejected Due to Font Size and Ingredient Name
A South Korean skincare brand shipped 5,000 units of a serum to Shanghai. The Chinese label had the correct ingredient list and warnings, but customs inspection found that the ingredient names used were direct English translations (e.g., “透明质酸钠” instead of “玻尿酸钠” – actually both might be acceptable depending on IECIC, but the specific problem was that the IECIC entry required “透明质酸钠” and the label used “玻尿酸钠”. Also, the font size measured 1.5 mm on a 30 cm² label (minimum should be 1.8 mm). The shipment was detained for 3 weeks, and the importer had to re‑label each unit at a cost of $0.50 per unit, plus storage fees. Total loss: $8,000. Lesson: always verify IECIC names and measure font size before mass production.
