Comprehensive verification of goods, documentation, and NOM labeling compliance at origin — so your cargo clears Mexican customs without holds, fines, or delays.
China is a major sourcing destination for consumer electronics, textiles, toys, furniture, auto parts, and building materials. With manufacturing spread across Guangdong, Zhejiang, Fujian, Jiangsu, and Shandong provinces, maintaining consistent product quality requires systematic quality control at every stage. Pre-Customs Clearance Inspection (Previo en Origen) in China gives you confidence that your products meet specifications before they ship.
Previo en Origen inspection is mandatory for many product categories entering Mexico. Failing this inspection at the Mexican border results in customs holds, fines of 250–300% of the duty value, storage fees, and potential destruction of goods. Catching compliance issues at origin costs a fraction of fixing them at destination. When sourcing from China, this is especially important because common challenges include inconsistent quality between batches, specification deviations, substituted materials, and mislabeling.
During a pre-customs clearance inspection (previo en origen) in China, goods, packaging, labeling, and all accompanying documentation are verified against Mexico's Customs Law (Article 42) and applicable NOM standards before shipment. Inspectors check product classification (tariff codes), country-of-origin marking, NOM compliance labels, commercial invoices, packing lists, certificates of origin, and phytosanitary or health certificates where required.
The inspector arrives at the supplier's factory or warehouse, verifies production completion, cross-references commercial documentation against the physical goods, checks NOM labeling requirements for each product category, photographs all findings including label placement and packaging markings, confirms correct tariff classification, and delivers a detailed compliance report within 24 hours — allowing you to correct any issues before the shipment leaves the origin country.
Our inspectors in China are experienced with Consumer Electronics, Textiles & Garments, Toys & Children's Products, Furniture & Homeware and understand the specific quality expectations for products manufactured in Guangdong, Zhejiang, Fujian, Jiangsu, and Shandong provinces. They conduct inspections when goods are fully produced, labeled, and packed — typically 5–10 days before the planned shipping date, following internationally recognized AQL sampling standards.
Based on our experience inspecting products in China, the most common issues our inspectors find include: missing or incorrect NOM labels, tariff misclassification, incomplete certificates of origin, incorrect country-of-origin marking, documentation discrepancies between invoice and physical goods, missing phytosanitary certificates, and non-compliant packaging materials.
Understanding these typical defects helps you set clear quality criteria and inspection checklists tailored to China's manufacturing environment.
When importing from China, buyers must consider: China enforces the CCC (China Compulsory Certification) mark for products sold domestically, covering electronics, toys, and automotive parts. Export products must comply with destination-country standards (CE, FCC, CPSIA). The China Export Commodity Inspection Law requires certain products to pass inspection before export. Buyers should verify factory compliance with relevant ISO standards and industry-specific certifications.. Our pre-customs clearance inspection (previo en origen) process in China includes verification of applicable compliance requirements, helping you avoid customs rejections and regulatory penalties.
Book inspections at least 48 hours in advance. Factories in the Pearl River Delta typically operate on tight schedules, especially before Chinese New Year. Our local inspectors are stationed across Guangdong, Zhejiang, Fujian, Jiangsu, and Shandong provinces, allowing us to reach most factories within 24–48 hours of booking confirmation.
We review the service order, importer details, product category, and applicable NOM standards. All reference documents are analyzed: commercial invoice, packing list, certificate of origin, quality and health certificates. Potential discrepancies are identified before arriving at the factory.
We photograph and record the container number, seal number, and exterior condition, verifying they match shipping documents. The empty container interior is inspected before loading: cleanliness, absence of residues, moisture damage, pests, or contamination from previous cargo.
We perform a complete count of every box, bundle, and pallet — no estimates. Quantities are broken down by SKU and product line, then compared against the packing list. Any discrepancy is immediately documented with photographic evidence.
Randomly selected boxes from different areas of the shipment are opened. We verify that actual contents match the commercial invoice description word for word: name, model, color, size, material, and country of manufacture. Product condition and packaging integrity are assessed.
Commercial invoice, packing list, certificate of origin, and customs declaration are cross-checked field by field. We verify mandatory fields: importer RFC (tax ID), full address, HS code per product, Incoterms, unit prices and totals. All documents must be originals or certified copies.
Every product is checked for Spanish-language labels with all mandatory information. We confirm compliance with the specific applicable NOM (NOM-004, NOM-020, NOM-050, NOM-051, NOM-141, NOM-024, and others). Each label is photographed in sufficient detail to be fully legible for the validation team.
We verify that the assigned HS code matches the actual product: material composition, end use, manufacturing process, and physical form. Preferential tariff claims (USMCA/T-MEC) are reviewed against the certificate of origin. Evidence is documented to support the classification at customs.
The entire container loading is supervised without interruption. A final recount is performed, the loaded container is photographed, and the new seal number is recorded. The complete report with all photographic evidence is delivered same-day so your customs broker can begin clearance immediately.
