First Line tracking

What is First Line?

First Line, known in Chinese as 壹号专线供应链有限公司 and registered under the English corporate name Shenzhen One Line Supply Chain Co., Ltd., is a cross-border e-commerce logistics company based in Shenzhen, China. The company was founded on January 2, 2018, during a period of rapid growth in demand for affordable and trackable shipping solutions between Chinese warehouses and Western consumer markets. It operates under the brand name FIRST LINE and is indexed by the carrier identifier firstline56 across the global tracking platforms that have integrated its services.

First Line is headquartered in the Baoan District of Shenzhen, in the Huaide Cuigang Industrial Park near Fuyong Street. This location places the company within one of China's most concentrated cross-border logistics clusters, close to the Hong Kong border and the manufacturing base of the Pearl River Delta. From its founding, First Line built its operations around dedicated shipping routes, known in Chinese as 专线, zhuanxian, rather than routing all shipments through standard postal infrastructure. This model involves aggregating parcels from multiple e-commerce sellers and moving them through controlled, high-frequency corridors to destinations in North America and Europe.

The company's customers are primarily cross-border e-commerce merchants selling on platforms such as Amazon, AliExpress, eBay, Wish, VOVA, and Alibaba International Station. Pricing and service terms are negotiated directly with sellers and logistics brokers rather than published publicly, reflecting a business-to-business orientation that differs from consumer-facing postal operators. First Line processes more than 100,000 parcels per day and maintains more than 45 collection points across China to handle inbound shipments from domestic e-commerce sellers.

Since its founding, First Line has expanded its service portfolio beyond basic parcel delivery to include sea freight dedicated lines, warehousing, API-based integration for automated shipping management, and batch order processing tools. This expansion reflects an effort to serve high-volume e-commerce sellers who need to manage logistics programmatically rather than through manual booking. The company obtained an ICP license and a public security filing in China, confirming its regulatory compliance and active operational presence. Its tracking profile is recognized and integrated into more than a dozen global parcel tracking aggregators, indicating a growing footprint in the cross-border logistics market.

Which countries does First Line deliver to?

First Line's main operational routes run from China to four primary destination markets. The United States, Canada, the United Kingdom, and continental Europe are the corridors most prominently featured in the company's service offerings, each served by a combination of air and sea freight options tailored to the volume and cost requirements of e-commerce sellers. These routes represent the core of First Line's logistics infrastructure and the destinations for which the company has established direct partner agreements and dedicated customs handling arrangements.

Beyond its primary corridors, third-party tracking aggregators identify Hong Kong, Singapore, and Malaysia as transshipment or regional nodes within First Line's operational network. Some tracking platform profiles attribute a coverage area of more than 100 countries and territories to the carrier, which reflects the reach made possible by its partnerships with major international carriers. For destinations outside the main corridors, final-mile delivery is handled by partners such as DHL, FedEx, UPS, DPD, Royal Mail, and China Post, depending on the specific destination country.

• United States: Served by air and sea freight dedicated lines, with T86 customs clearance available for small packages
• Canada: Air freight route with hubs at Vancouver and Toronto, with Canada Post handling final-mile delivery to recipients
• United Kingdom: Served through the SKYNET UK service, with SKYNET responsible for final-mile distribution across the country
• Continental Europe: Covered by the Europe air freight dedicated line service
• Southeast and East Asia: Hong Kong, Singapore, and Malaysia serve as transshipment or regional operational nodes
• Global destinations: More than 100 countries and territories reachable through partnerships with DHL, FedEx, UPS, DPD, Royal Mail, and China Post

International shipments from China are routed through First Line's network until they reach the destination country, at which point the final-mile carrier takes over distribution. A parcel to Canada, for example, will be handed to Canada Post after clearing customs at the Vancouver or Toronto hub, while a shipment to the United Kingdom will be distributed by SKYNET after arriving in the country. This carrier collaboration model allows First Line to extend its reach to destinations where it does not operate its own last-mile delivery infrastructure.

What are the First Line services and delivery times?

First Line organizes its shipping products into two main categories. The first covers small package services, designed for the lightweight and compact shipments typical of e-commerce orders. The second covers dedicated line services, which operate on fixed, managed corridors between China and specific destination markets and are aimed at higher-volume or more time-sensitive shipments. Within each category, the company offers multiple specific products differentiated by transport mode, destination, and the customs handling arrangement included in the price.

• T86 clearance small package (US): Small packages to the United States processed through T86 customs clearance, a CBP entry type designed for low-value e-commerce imports
• Standard US parcel: Small package service for shipments to the United States via standard routing
• US sea freight parcel: A lower-cost, sea-based option for small packages bound for the United States
• Canada parcel: Small package service for shipments to Canada, with Canada Post handling final-mile delivery to recipients
• Standard postal parcel: Available with self-collection or transport options for general postal routing
• Express parcel: A faster small package option for more time-sensitive shipments
• SKYNET UK: Small package service for the United Kingdom, with SKYNET responsible for final delivery to recipients
• Air freight dedicated line: Dedicated corridor service by air with double-clearance and taxes included in the price
• Sea freight dedicated line: Dedicated corridor service by sea with double-clearance and taxes included, marketed as a fast sea shipping option
• US air freight: A dedicated air freight service specifically for US-bound shipments
• Europe air freight: A dedicated air freight service covering continental European destinations
• US sea freight dedicated line: A sea-based dedicated corridor for higher-volume US-bound cargo

First Line does not publish official transit time commitments for its various service products. Based on estimates reported by third-party tracking aggregators, standard international shipments from China typically arrive within 5 to 14 business days, depending on the destination and the speed of customs processing at the receiving end. Certain routes are associated with shorter estimates of 3 to 7 business days, which likely corresponds to the faster air freight dedicated line options. These figures are approximations and can vary based on shipment volume, customs hold times, and the final-mile carrier's own delivery schedule.

In addition to its shipping services, First Line offers a technology layer for e-commerce sellers who need to manage logistics at scale. This includes an online price inquiry tool, a shipment tracking portal, a data collection and batch order management system, client-side software, and full API integration capabilities. These tools allow sellers to connect First Line's shipping operations directly into their order management workflows, enabling the systematic processing of large shipment volumes without manual booking for each order.

What are the First Line rates and maximum dimensions accepted?

First Line does not publish a public rate card, which is consistent with its focus on business clients rather than individual shippers. The official website provides a price inquiry tool that allows registered clients to obtain quotes for specific shipments by submitting the relevant parameters. Pricing calculations take into account actual weight, volumetric weight, destination, and the selected service tier, including whether the shipment is a small package or a dedicated line product and whether it moves by air or by sea.

No specific maximum weight or dimension limits are publicly disclosed for any of First Line's service products. Given that the portfolio spans both small package products aligned with typical e-commerce parcel norms and sea freight options capable of accommodating larger cargo, the permissible specifications vary considerably depending on the service selected. Sellers and logistics brokers obtain the applicable limits for a given service through direct consultation with First Line's account management team or by using the price inquiry tool on the client portal.

• Pricing model: Quotes generated through the official price inquiry tool based on shipment parameters; no public rate card is available
• Weight calculation: Both actual weight and volumetric weight are used to determine the chargeable weight
• Service tier pricing: Small package and dedicated line services are each priced according to their own rate structures, with separate pricing for air and sea options within each tier
• Maximum weight and dimensions: No publicly disclosed limits; applicable specifications vary by service type and are provided upon direct inquiry

What are the First Line delivery options?

For shipments to Canada, final-mile delivery is handled by Canada Post after parcels arrive at the Canadian hubs in Vancouver or Toronto. At that stage, the shipment enters Canada Post's domestic distribution network for delivery to the recipient's address. The specific options available to recipients for rescheduling delivery, redirecting a parcel, or collecting from a designated pickup point follow Canada Post's standard procedures and are outside First Line's direct operational scope once the handover has occurred.

For shipments to the United Kingdom, First Line uses SKYNET as its final-mile delivery partner. After a parcel clears customs and enters the domestic UK network, SKYNET is responsible for distributing it to the recipient's address. The delivery options available to UK recipients at this stage, including any provisions for redelivery or collection, are governed by SKYNET's own service terms. For shipments to the United States and continental Europe, the final-mile carrier depends on the specific route and destination, with DHL, FedEx, UPS, and DPD among the partner carriers referenced in First Line's carrier documentation.

• Canada final-mile delivery: Managed by Canada Post after arrival and customs clearance at the Vancouver or Toronto hub
• United Kingdom final-mile delivery: Managed by SKYNET after customs clearance and entry into the domestic UK distribution network
• United States and Europe final-mile: Handled by carrier partners including DHL, FedEx, UPS, and DPD depending on the specific destination

Does First Line handle international shipments and customs formalities?

International shipping is the core business of First Line. All of the company's advertised services are cross-border routes running from China to destinations in North America, Europe, and beyond. The company offers double-clearance services, known in Chinese as 双清, shuang qing, on its dedicated lines. Under this arrangement, First Line or its local partners handle both export customs clearance in China and import customs clearance in the destination country on behalf of the shipper, removing a significant administrative burden from e-commerce sellers who would otherwise need to manage these processes independently.

Several of First Line's service tiers carry a tax-included designation, described in Chinese as 包税, bao shui. This corresponds to a Delivered Duty Paid arrangement, in which all applicable import duties and taxes are built into the shipping cost agreed upon with the seller at the time of booking. Under this model, the end recipient does not receive a separate bill for customs duties upon delivery. This approach makes cost estimation more predictable for sellers shipping to markets with import duties and avoids unexpected charges for the final customer.

For small packages bound for the United States, First Line applies T86 customs clearance, an entry type administered by US Customs and Border Protection that is designed specifically for low-value e-commerce imports. This pathway processes parcels faster than formal customs entry and is widely used by dedicated-line carriers operating in the China-to-US corridor. No specific list of prohibited items has been published by First Line, but all shipments are subject to Chinese export regulations and the import laws of the destination country, including restrictions maintained by US CBP, the Canada Border Services Agency, and UK Border Force.

• Double clearance (双清): Export customs in China and import customs in the destination country are both handled by First Line or its partners on behalf of the shipper
• Tax-included pricing (包税): Delivered Duty Paid model where import duties and taxes are included in the agreed shipping cost, with no additional charges billed to the recipient at delivery
• T86 clearance (United States): CBP entry type for low-value e-commerce imports, applied to small packages entering the United States
• US import customs authority: US Customs and Border Protection (CBP)
• Canada import customs authority: Canada Border Services Agency (CBSA)
• UK import customs authority: His Majesty's Revenue and Customs (HMRC) and UK Border Force

Understanding tracking statuses

When tracking a First Line shipment, different status messages appear as the parcel progresses through the shipping network. These indicators are visible through First Line's own client portal as well as through the third-party tracking platforms that have integrated the carrier. The identifier firstline56 is used by the majority of these platforms, while uses the internal registration ID 190405-first-line. The table below describes the main status messages and what each one indicates about the parcel's position in the delivery process.
