For many Chinese consumers, all they care is whether or not the new tax policies will impact their Daigou experience.
The grey market of Daigou - a Chinese term translated as "buying on behalf" - has been a major channel for Chinese shoppers to buy luxury goods that are heavily taxed in mainland China.
Through overseas Daigou agents, products can be brought back to China in person or by mail without declaring at customs or paying import duties.
Daigou is not a risk-free business. Once caught by the customs authorities, both agents and consumers could face smuggling charges, resulting in large fines, or even jail sentences.
However, it seems to be a risk that many are willing to take.
"The demand for overseas purchases is huge," said Jan Qu, 30, a part-time Daigou agent based in New York. "Cheaper prices are just one reason. Many Chinese shoppers also have doubts in the quality of domestically-made products and that's why they are buying overseas."
Despite occasional punishments, law enforcement towards Daigou has been relatively loose, helping this grey market boom in recent years.
Daigou sales contributed by Chinese shoppers, although saw a decline since 2014 partially due to China's economy slowdown and corruption crackdown, is now estimated to be worth 43 billion yuan, or roughly 38 percent of all luxury sales in mainland China, according to a report by Bain & Company.
And China's flourishing e-commerce sites and social media, such as Alibaba-backed Taobao, China's twitter-like Weibo and the Tencent-backed Wechat, are all helping this grey industry to get bigger.
"I have clients on all Taobao, Weibo and Wechat," said Qu. "Buyers on Taobao are more suspicious because they don't trust me, but clients on Weibo and Wechat are mostly introduced by friends so they wouldn't worry too much."
While Chinese shoppers are big spenders overseas, brick and mortar stores in China have been losing profits, weakening China's efforts to boost domestic consumption and resulting in a big loss of the government's tax revenue.
In 2014, cross-border e-commerce and overseas purchases reached hundreds of billions of yuan, while the personal postal article tax generated just 1.3 billion yuan for the government.
The tougher tax rules on cross-border e-commerce purchases - even though they are now a year away - have made many Daigou agents worried about stricter airport customs checks.
